How much RAM do your android phones/PC’s actually need?What is the difference between static and dynamic RAM?

While buying or comparing phones/PC we often find the term RAM that often confuse us. We all know that RAM is one of the most important components of a device but what actually is RAM?
What is the work of RAM? How much RAM do our PC or smart phone need?
Which generation of RAM is better?

This article will provide you all information related to RAM.
Click on the below topics to get more knowledge on that topic.

1.What is RAM?

2.Know more about RAM.

How does RAM work?

Types of RAM.

Difference between DRAM and SRAM.

What are the different generations of RAM?

How much RAM does your phones/PC actually need?

First of all What is RAM?

RAM stands for Random Access Memory.

Now let us learn about RAM, from real life situations.

Suppose you are working in an office. You have been provided a table for work. And all the files and important things are kept in another room i.e. file room.

So to complete your work, you have to go the file room and bring the all important files. Suppose your table is small so, you will be able to keep only few important files at a time. And you have to go to the file room to bring the next needed file again and again.

Because of small table you have to work harder and it will also consume more energy and time. But, if you have a big table then you can keep all the files and you will able to finish the work faster, with less energy consumption.

So, if we compare this situation with smart phone, PC, or any other device. Then the file room can be compared with device’s internal storage. Table can be compared with device’s RAM and you can be compared with the device’s processor.

Now, if the RAM has higher storage capacity then the processor does not have to work more and processor can finish the work in less time with less power usage.

Know more about RAM.

It is named Random Access Memory(RAM) because CPU or SOC can access any memory location of the RAM.

RAM is a volatile memory – it means that RAM can store the information in it, until there is continuous power supply. Whenever there is power cut, RAM looses it’s all data. So it is called short term memory.

It stores that data only which currently needs to be processed. Example: When you open a photo editing software then all the information of the photo editing software will get transferred to RAM from device internal storage.

RAM is the fastest and the costliest part of a computer.

It is the read-write memory of the computer – It means that CPU or SOC can read instructions from RAM and after the processing the instructions, CPU can write results on the RAM.

How does RAM work?

Suppose you have installed an application in your device, that application will be stored in your device’s internal storage.

Whenever you run the application, then application will be transferred to the RAM from internal storage, so that RAM can send information to CPU or SOC faster.

In order to run a program, it needs to be loaded into RAM first. If RAM's memory is less, the RAM may not hold all the data & information the processor requires to run the program.

In that case ROM is used as RAM but, ROM has slow read-write speed so it affects the processing speed and makes our computer slow.

So for better performance and multitasking our device needs more RAM.

Types of RAM.

You must be wandering What are the different types of RAM?

Here is the detailed information.

There are 2 types of RAM.

1. DRAM(Dynamic Random Access Memory):

DRAM is manufactured by capacitors.

Capacitors are like small buckets that store electricity.
Capacitor holds the data i.e. 1 or 0.
Capacitors of DRAM have to be refreshed with electricity because capacitors do not hold the charge for long time.
They continuously loose charge.

From this, it got the name of Dynamic RAM.

The capacitors have to be dynamically refreshed oftenly, otherwise RAM will forget(erase) the holding information.
DRAM stores 1 bit of data in 1 transistor.

2. SRAM(Static Random Access Memory):

Static RAM requires the constant flow of the power to retain the data in it.

Any power cut may lead to loss of all data in the RAM.
It is a very costly RAM.
SRAM stores 1 bit of data in 6 transistors.

Difference between DRAM and SRAM

Here is a table that provides the difference between DRAM and SRAM.

Dynamic RAM and Static RAM

What are the Different generations of RAM?

Before knowing about RAM generations, let’s understand some basic terms which will help us to understand about the RAM generations.

Power consumption – lesser the power consumption, better the RAM will be.

RAM frequency – more will be the RAM frequency, better the RAM will be.

RAM CAS Latency – While running an application, CPU or SOC continuously requires data about the application. So, CPU requests the memory controller to provide the data and memory controller will request the RAM to provide the data. The time taken by the RAM to provide the data to memory controller is known as latency.

Lesser will be the latency better will be the RAM.

Size of the transistors – lesser the size of transistors, better will be the process because, it will consume less power and because of the small size we can use more transistors that will increase the storage capacity of RAM.

RAM generations are:

1. DDR1

It has 188 pins.

The power consumption of DDR1 RAM is 2.5 V (volt).

Latency of DDR1 RAM is 3 ns (nano second).

Frequency of DDR1 RAM is 200-400 MHz

2. DDR2

It has 240 pins.

The power consumption of DDR2 RAM is 1.8 V (volt).

Latency of DDR1 RAM is 5-6 ns (nano second).

Frequency of DDR1 RAM is 400-800 MHz

3. DDR3

It has 240 pins.

The power consumption of DDR3 RAM is 1.5 V (volt).

Latency of DDR1 RAM is 9 ns (nano second).

Frequency of DDR1 RAM is 1066-2133 MHz

4. DDR4

It has 288 pins.

The power consumption of DDR4 RAM is 1.2 V (volt).

Latency of DDR1 RAM is 15 ns (nano second).

Frequency of DDR1 RAM is 2133-4133 MHz

To select the best RAM, go on the number. Greater will be the number, better will be the RAM.

i.e. DDR4 RAM is better RAM than DDR3.

How much RAM does your android phones/PC actually need?

It depends upon the usage types, whether you are a normal user, professional user or a high performance gamer, etc.

For phone:

Normal user – if you are a normal user, i.e. the one who plays small games, plays music, watch YouTube videos, and use social media, then 4 GB RAM is sufficient for your smart phone.

Moderate user – If you are professional gamer, you play games like PUBG, etc, do lots of multitasking, then 6 GB RAM is enough for your smart phone.

Very advanced user – If you are a very advanced user then, 8 GB RAM is required for your smart phone.

For PC:

For a normal user – if you are a normal user i.e. the one who browses net, watch YouTube videos, do simple excel or official work. Your PC requires 8 GB of RAM.

If you are a professional gamer- you play high performance game with online streaming then, your PC needs 16 GB RAM.

Heavy User- If you are a professional video editor, you do animation work, you are a 3 D model designer, or you do heavy multitasking, then your PC requires 32 GB RAM.

It is always better to buy smart phone or a PC having more RAM than your requirement as upcoming high performance softwares requires more RAM.

Now I hope you got sufficient knowledge about, what is RAM? Types of RAM? and much more.

15 smartphone sensors Explained !

2020-08-22T15:20:00.001+05:30

The smart phone, also called a mini computer can perform so many tasks & make our life easier.

But, have you ever wondered, how our smart phone works so smartly. Do you know there are so many sensors present in our smart phone which makes it smarter?

Let us now see, how many sensors are present in our smart phone and what their uses are.

1. Accelerometer

Accelerometer detects the motion of the smart phone. Auto rotate feature is also handled by the accelerometer.

Accelerometer senses the position your smart phone. It can also sense whether your phone is on the ground or it is in your hand.

2. Magnetometer

Magnetometer plays very important role in navigation.

It works as a compass. It detects the magnetic field and through that it detects the north, south, east and west direction.

Navigation software uses the data of accelerometer, gyroscope, magnetometer and GPS and then it shows the correct position, correct direction and distance.

3. GPS(Global positioning system)

This sensor tells the position of your smart phone on the earth.

It will tell you your phone’s exact position on the Earth without using internet but to see the further details like street name, place name, etc you need the access of internet.

4. Proximity sensor

In 90% of the smart phone you will find this sensor near the front camera.

When you are on a call, and bring your phone near your ear then you may have noticed that your smart phone screen gets automatically off. This is done by the help of proximity sensor.

Proximity sensor send infrared rays to detect any object in front of the phone(our ears).

With this process, sensor will understand that there is an object near the smart phone and it will turn off the screen.

With its help we can get rid of unwanted touch on the phone’s screen by our cheeks .Turning off the screen also helps to save battery.

5. Ambient light sensor

This is found near the smart phone’s front camera mainly.

This sensor judges the intensity of surrounding light.

The auto brightness feature performs very well because of ambient light sensor.

If there is more light in the surrounding (for ex, in a bright sunny day) then the brightness becomes automatically high. And if, in the surrounding there is less light (like a dark room) then the brightness becomes low.

Because of this sensor we get good viewing experience.

6. Gyroscope

It is the advanced version of accelerometer.

It calculates the angle or degree at which your phone is kept. It calculates finer details of the angular motion. It can sense the angle to which the phone is rotated or the direction to which it is moved.

While playing racing games, you may have noticed that by the movement of your phone you can control the movement of car in the game. When you tilt your phone downwards from left side, then the car turns towards the left direction and vice versa.

When you click 360⁰ image(panorama) that is also possible through gyroscope.it calculates every angle of the movement of smart phone so that we can get pictures of every angle.

Watching VR (virtual reality) video is also possible through this sensor. It calculates the every movement of the phone and changes the viewing angle of the video.

Gyroscope

7. Audio sensor/microphone

Common user knows the audio sensor through the name of microphone.

Audio sensor senses the audio. When you take a call, give voice command to the smart phone or recording any audio it gets activated. It also measures the intensity of the voice.

8. Fingerprint sensor

It stores our fingerprint information. When we try to open our smart phone using fingerprint, it matches the fingerprint info and unlocks the smart phone.

9. Pedometer

It counts the footsteps.

By the help of accelerometer, gyroscope it takes the input and then it calculates the number of footsteps you have walked.

10. Barometer

It measures the altitude. It measures your altitude from the sea level. It also measures the atmospheric pressure.

It helps the GPS (Global positioning system) to provide more accurate data.

Some applications that measure the distance, you have climbed or came down is done by the help of barometer.

11. Thermometer

Generally there is one internal thermometer but in some smart phones, there is an external thermometer sensor also present.

Internal thermometer sensor – it measures the temperature of the smart phone. If the temperature of the phone becomes very high, then by the help of certain software present, smart phone gets automatically switched off.

If there will be no internal thermometer in the phone, then due to overheat components of the smart phone may burn.

External thermometer sensor – it measures the temperature of the atmosphere.

12. IR (Infrared) sensor

By the help of infrared sensor, we can use our smart phone as a remote to control various devices such as our TV, speaker, AC, etc.

13. NFC(Near field communication)

It helps to communicate and share files between two devices having less separation (not more and 3-4 cm).

With one tap you can send or receive any type of data but with slow speed.

14. TOF (time of flight)

It is the camera’s sensor which measures the distance between subject and the background by the help of infrared rays.
It helps in producing good bokeh mode picture. In the camera application we get an option of portrait mode to click pictures in portrait mode, that is only possible because of TOF sensor.

We get a picture in which, the main focus remains on the subject and rest of things remains out of focus (blur).

15. Air humidity and heart rate sensor

Air humidity sensor: It measures the humidity in the atmosphere and tells whether the humidity is suitable for you or not.

Heart rate sensor: It uses led flash and optical sensor to measure our heart rate.

Now I hope that, we have made you understand the different sensors present in our smart phone and what are their uses.

Please tell us, how useful you found this article and if you find any missing points or mistakes in our article, then please let us know in the comment section below.

That will help us to improve ourselves.

Smartphone- Camera terms explained !

2020-08-10T16:13:00.003+05:30

Whenever you compare your smart phone’s camera with other smart phone’s camera you often find some terms whose meanings you don’t know.

In this article I will explain each and every term related to smart phone’s camera.

To become a smart phone camera expert, continue reading this article.

1. BOKEH

Bokeh is a Japanese word which means out of focus.

When you click a picture of any subject, then the main focus remains on the subject and rest of things remain out of focus.

For example:

When you click a picture of your friend, then the main focus remains on your friend and rest of the things like background trees and walls, remains out of focus or we can say blur.

In cameras like DSLR, bokeh mode is done through hardware and in smart phones, bokeh mode is done through software.

2. ISO

ISO tells us that, how much the camera’s sensor is sensitive towards the light.

If ISO is 100 that means camera’s sensor is less sensitive towards the light.

It means, to get a good picture, your smart phone’s camera requires good amount of light. And that camera is capable of clicking good picture in bright light.

If your smart phone’s camera has an ISO between 2400-3200, then your camera will able to click good picture in low light.

When you click picture in high ISO, there will be noise in the picture i.e. picture will be not clear and the pixels will be visible in the picture.

Whereas, when you click picture in low ISO, you get clear and good picture but it requires good amount of light.

Camera terms explained

3. RESOLUTION

Image is made up of pixels.

Different color pixels combine together to form a picture. In a picture millions of pixels are present.

If your phone has a 13 MP (mega pixel) camera, it means that, it clicks pictures having 13 million pixels in it.

If your smart phone has 48 MP camera, then it means, it will click pictures having 48 million pixels in it.

So, resolution means how many pixels are present in a picture. If a picture has more resolution, then that picture will be clearer.

4. APERTURE

Whenever you open your camera and try to click a picture, then the camera’s lens opens to gather information about the view/surrounding image.

After gathering the information, the camera’s lens closes.

In simple language, camera's lens is like a door.

Door opens to gather information. If door opens more then, more information can enter and if, doors opens less then, very less information can come inside.

Similar things happen in the camera’s lens.

When it opens more, it can gather more light and more information about the picture. Therefore we will get an excellent output i.e. a very good pic.

If the aperture of the camera is of F1.7 or F1.8 that means, the size of opening of lens is more.

If the aperture of camera is F2.3 or F2.8 then the opening size of camera’s lens is less.

Camera's Aperture

So, it is recommended for users to buy smart phone whose camera has a small aperture than F1.8.

It will produce a brighter and clear picture.

Especially the cameras having small apertures perform excellent in low light.

5. RAW files

Any picture’s RAW file (original picture) occupies more space, so RAW file is compressed and stored in jpg format, so that it occupies less space.

RAW files stores more information about picture like information about light, colours, etc that’s why RAW files occupy more space.

Experts who require high quality images or videos, they store them in RAW file. Normal user should store the file in jpg format only.

6. Night Mode

Night mode is based on the software, by the help of certain algorithm, it brings light in the picture.

Night mode checks the darker pixel and makes the entire dark pixels brighter.

7. MACRO LENS

For small objects, we use macro lens.

When you try to capture an image of small objects like insects or fine particles of sand etc, then you will find that normal camera is not able to focus on the insect and we are not getting a clear image.

Here we use macro lens, to get clear image of such small objects.

8. Ultra wide lens

Ultra wide lens are in oval shape, so that it can capture picture in wider angle.

9. TOF (Time Of Flight) lens

TOF measures the distance between the main subject (cat, dog, human, etc) and the background (wall, etc) by the help of infrared rays.

Because of this lens, we get good bokeh mode picture.

TOF sensor tells the camera to keep a focus on the main subject and rest of the things out of focus (blur).

10. Artificial Intelligence (AI) mode –

By the help of certain algorithms, camera detects the picture weather it is of a flower, food, person or anything.

After detecting the picture, it does some settings and improves the picture and make the picture pleasing to the eyes and catchy.

11. HDR (High Dynamic range)

This feature comes in use, when you take a picture of anything in which, both- a dark side as well as a bright side is present.

For example:

When you take the picture of a tree in a bright sunny day then, if you try to focus on the bright sunny side, then the tree and its shadow both will become completely dark.

And when you try to focus on the darker side, then, the bright sun will become completely white and the sun will be not visible in the picture.

So to get a good picture in this condition we take the help of HDR.

When we click a picture using HDR, then our camera clicks two images.

One focusing on the brighter side and another focusing on the darker side.

After that, our camera combines both the pictures and we get a well balanced picture as our output.

12.Slow Motion –

This feature can be used to record videos in slow motion. Here is how it works.

When you shoot a normal video, it is recorded at 30 fps (Frames Per Second).

It means that, camera will click 30 frames (picture) per second and then it will combine the frames to form 1 second video.

But when you record a video in slow motion, then the camera clicks 240 frames per second.

It means camera will shoot the video in 240 fps and then that video is converted into 30 fps i.e. 30 frames per second. So, when you shoot a 1 second slow motion video, it is converted to an 8 seconds video.

13. Time Laps –

This feature can be used to record videos in faster speed.

Time laps is just the opposite of slow motion.

When you shoot a normal video, then the camera clicks 30 frames per second. And when you use time lapse, time laps camera will click only 1 frame per second. So when you shoot a video of 30 seconds, the video you will get will be of 1 second.

In slow motion, camera clicks more frames per second and in time laps, camera clicks fewer frames per second.

14. EIS (Electronic image stabilization) and OIS (optical image stabilization)

While recording a video, we often find that our hand shake and because of that we get a shaky and an unstable video. To make a video stable, EIS and OIS are helpful.

1. OIS (optical image stabilization)

OIS makes a video stable by hardware. It means that the camera moves up and down, left and right to compensate the movement of hand.

For example: if the phone moves downwards, then to compensate the phone’s movement, the camera will move upwards. Similar things happens for all types of movements. And the output we get is a stable video.

2. EIS (Electronic image stabilization)

It makes the video stable by the help of software and certain algorithms.

It crops the video from all side by the help of software and adjusts the video and in the output we get a stable video.

15. Optical zoom, Hybrid zoom and Digital zoom.

1. Optical zoom -

When you zoom from a DSLR camera, then it is done through hardware. Actual movement i.e. forward and backward of lens zooming takes place. This is known as optical zoom.

In some flagship smart phones, we find optical zoom. The lens move forward and backward to adjust the zoom.

In optical zoom there is no loss of picture quality.

2. Digital zoom –

Digital zoom is done through software. It is same like, we zoom picture manually.

In digital zoom there is loss of picture quality.

3. Hybrid zoom –

It is the mixture of optical and digital zoom.

If we assume that a phone has 5X hybrid zoom then, it means that up-to 3X it has optical zoom and further remaining 2X is digital zoom.

In Hybrid zoom there is no loss of picture quality until zooming takes place under optical zoom.

Conclusion

we hope that we have clearly explained the various terms used in camera application, in easy language.

Smartphone battery care - tips,tricks and myths.

2020-08-10T15:35:00.001+05:30

Smartphone battery care- tips and tricks. Smartphone battery myths.

You brought a new phone and you want to use it for long lasting period, say 3-4 years, but smart phone battery power, becomes low after one year of usage.

If you want your smart phone battery to last very long, then continue reading this article, you will get to know about smart phone battery care tips and tricks, smart phone battery myths and many more things to know.

Today almost all smart phones have non removable battery, which means for a normal user, it is not possible to replace the battery by their own.

So to replace your battery, you have to go to service center which costs you a lot. That's why, it is very important to take care of your smart phone’s battery.

Battery is the only component in our smart phone which has the least life.

1. Smartphone’s battery care tips and tricks.

Good charging habits – never drain your phone's battery percentage to 0% and then charge up to 100 %.
Try to charge your phone three to four times in a day with a time interval of 30-40 min a time.
Don't bring the Smartphone’s battery percentage less than 20% and more than 80%.
Don't use the charger which has the output rating, less or more than the prescribed output rating of the Smartphone.

Example: If your Smartphone supports 15W (watt) of charging, then don’t charge with a charger having output rating of 10W or 28W.

If you find that your Smartphone is overheating while charging then, remove your phone from charging.
Do not charge your Smartphone in warm or extremely cold conditions.
In every 25-30 days, drain your battery percentage to 0% and then charge it again to 100%, in a single interval of charge. This will help the Smartphone’s battery to regain its original power.
Use thicker cable in charger because, thinner cable offer more resistance which lead to slow charging and produce more heat. All these will decrease your Smartphone’s battery life.

Smartphone battery care- tips, tricks and myths
Remove your phone's protective case while charging, so that phone doesn’t over heat.
Never keep your phone switch offer more than 20 days, it will degrade battery performance.
If your Smartphone has AMOLED screen, then use overall dark mode. It will boost your battery's performance by 40-50%.
In other type of screens, this will boost battery's performance by 20%.
Keep auto brightness off, whenever it is possible for you and keep the brightness low, as much as possible for you.
If your Smartphone receives any update, then do not update for one week because in some updates there are some bugs which may degrade your battery's performance.
Go and check, which all apps are using more battery percentage, and if possible try to uninstall them.

Use Facebook lite instead of Facebook because Facebook use lots of battery's percentage.
Try to keep your screen off time, less than 1 min.
Keep battery saver mode ON, because it will keep NFC, GPS, and Bluetooth etc off, whenever it is not in use.
Keep the notifications off of those applications which send useless notifications or unwanted notifications.
Don’t use live wallpaper.
Keep your system and apps updated, because updated applications have better features and updated application use less battery power as compared to not updated applications.
Keep the sync on for only important applications because, in the background syncing always take place and it uses little bit of battery percentage.
Never charge your Smartphone during lightning and thunder. Any voltage fluctuation my damage your phone and battery both.

2. Smartphone battery myths.

People often hear various myths, about phone's battery. Below table will provide all the realities and facts of those myths.

Smartphone battery myths and reality

3. More about Smartphone's battery.

Every Smartphone's battery has 1000 recharge cycle life. It means that you can charge your phone up to 100% and discharge it to 0%, thousand times.

After that, the original power of battery will be almost gone. 1000 recharge life cycle is equal to 2.5 years.

Battery manufacturers say that if you complete 400 recharge cycles, then the battery's performance will decrease and reach to 80% of the original power capacity of the battery.

Charging of battery from 0% to 100% is known as 1 recharge cycle.

If we assume that battery is a human then,

Battery will be happiest at 50%.

Below 10% battery feels weak and above 90% battery feels distressed.

At extreme high and extreme low battery percentage battery do not feels well. So use partial charging that means try to maintain battery percentage between 20% to 80%.

4. Does the fast charger affect the phone's battery life?

Yes. Fast charger affects the phone.

It puts more stress on the phone’s battery.

Fast charger produces more heat, and one thing that you should know is, "Heat is the biggest enemy of the battery!".

5. What are the types of batteries in different Smart phones?

There are two types of batteries used in Smart phones.

Lithium-ion batteries
Lithium-polymer batteries

6. Difference between lithium-ion batteries and lithium-polymer batteries.

Lithium-ion batteries are based on old technology, where as lithium-polymer batteries are based on new technology.
Lithium-ion batteries can be manufactured in only fixed shape where as we can make flexible lithium-polymer batteries.
Lithium-ions can store more energy density as compared to lithium-polymer batteries.
Lithium-ion batteries have less output energy level, which means it gets discharged at low speed, where as lithium-polymer batteries have high output energy level.
In lithium-ion, polymers have the problem of getting over charged, where as lithium-polymer batteries have no problem of getting over charged.
Lithium-ion batteries cost less to manufacture but lithium-polymer batteries cost more in manufacturing.

7. How much safe lithium-ion and lithium-polymer batteries are?

If you have noticed earlier there were batteries having capacity of 1000-1500 mili ampere, but today's batteries have higher capacity i.e. 5000-6000 mili ampere.

Since the sizes of the batteries are not increasing, battery manufacturers are packing batteries more dense.

Due to dense manufacturing of batteries, it can easily blast on small amount of pressure/stress too.

We all know that, hundreds of Samsung galaxy note 7, have exploded.

This is all due to the wrong manufacturing process of its battery.

But it's rare. One out of million Smartphone's, batteries explodes.

In every Smartphone battery, there is an electrode which is very useful. It gets very easily charged and discharged.

But as it is present in liquid state, any mistake can lead to short circuit and battery can explode.

8. Why do Smartphone batteries explode?

Pressure on the batteries - when any pressure is applied to the battery, then, short circuit takes place inside the battery because of which, batteries explode.
Over heating of batteries – when battery gets heated above 80 degree Celsius, then it explodes. But in today’s Smart phones, there is an inbuilt circuit which monitors the temperature of the Smartphone. When the temperature becomes very high, the phone gets automatically switched off.
Dendrite formation – during charging and discharging ions move from negative terminal to positive terminal and vice versa. During the movement of ions, dendrite formation takes place. When it becomes hard, then it pierces the separator leading to short circuit and eventually blasting.

9. Why does the company uses user non removable batteries?

Non removal batteries are safe because of different layers of protection it is coated with. When they fall, these layers do not separate and due to hard back cover, batteries are not damaged.
Non removable batteries can be made in any shape, to maximize the capacity of battery. For example; iPhone X has a ‘L’ shaped battery.

It shows that company can utilize the free space in the phone easily.
It also maximizes the capacity of the phone.

3. It is not possible to make thinner phones with metal or glass back with user-removable battery.

4.As we know that, the Smartphone's batteries start degrading very fast. After 2 to 2.5 years, the phone's batteries get worst.

It also affects the performance of the phone and all these things irritate the users.
This results in quitting the old phone and buying a new one.

Conclusion

This article gives all necessary information on tips and tricks to charge and maintain a good and healthy battery for your smart device. we have provided other additional information too. Hope readers are satisfied with the above information.

Near Field Communication (NFC)

Introduction.

Many of us may not be knowing about a wireless sharing feature available in our devices.

Yes, I am talking about NFC.

In this article you can get all your doubts and questions cleared about NFC.

What is NFC? How it works? What are NFC tags and NFC mode? Difference between Bluetooth and NFC. How to use NFC? How to be safe from NFC hacking? and lots more!

Near Field Communication(NFC)

What is NFC and its full form ?

NFC is a wireless service. NFC stands for Near field communication.

As it is by name, we can understand that, it creates a communication field around the device.

With the help of that, we can send or receive any kind of data. It works in very small distance between two devices, nearly 3-4 cm maximum.

During the communication, very less battery percentage is used and electromagnetic radio waves are used for communication.

What are the different NFC modes?

There are three NFC modes,which we can use for different purposes.

Peer to peer mode – In this mode, both device should have NFC active, then only, they can transfer or receive data from one device to another device.
Read/ write mode – In this mode, one way of data transfer takes place, for example- Through NFC tags.
Card emulator mode – In this mode, you can use your NFC device as a card, like debit card, credit card etc.

What are NFC tags?

There is a micro chip in our device, that stores data or commands, that is called NFC tag. It stores very less data.

In a NFC tag, you can give command through your smart phone by using different applications.

After storing command in your NFC tag, if you tap that NFC tag with other NFC device, then that command will be executed in that device.

Read more: Smartphone battery care, tips, tricks and myths.

What are the uses of NFC and why should we use it?

we should use it because it provides various features such as:-

Data transfer with easy steps.
Mobile payment – in your smart phone you can store your card details and when you need to pay ,select your card ⏩ turn on the NFC ⏩ and tap the paying machine with your device.
NFC business card – you can store your information in NFC card ,which you can use to give to your client.
NFC in camera – today in every camera like DSLR, there is an in built NFC feature. It can be used by just taping on the camera with your NFC device like smart phone, you will get all photos and videos in your NFC device(smart phone).

Read more: Smart phone Rooting! Know it all.

How to turn on NFC in your smart phone?

Go to settings of your smartphone.
Then go to connection/connection and sharing.
Then you will find an option NFC and payment, turn it ON.

How to use NFC in your device?

Turn on NFC in your smart phone.
Then open the image/ application/video/file, that you want to share.
Then bring the both device in contact.
Then, an option will appear "touch to the beam" click on that and that file/image/video/etc, will be shared.

Should we keep NFC on or off ?

If you are not using NFC regularly, then you must keep it OFF.

You should keep your NFC off in your device, because, if anybody finds your device with NFC on, then they can easily send or receive data from your smart phone.

They can also send some malware in your device.

Difference between Bluetooth and NFC.

Bluetooth pairing takes place at a range of 33 feet maximum and NFC pairing can take place at range of 3-4 cm maximum.
Bluetooth can share file at speed of 1-3 mbits/second where as NFC can share file at speed at speed of 424 kbits/second.
One Bluetooth device can connect maximum 7 device for communication at time where as one NFC device can connect only one device at a time.

How to be safe from NFC hacking?

Keep your NFC OFF when you are not using!

NFC was made for convenience in sharing files, but it became an easy tool for hackers to hack your device.

Since no authentication is required to connect any NFC device. Just one tap to your NFC device and BOOM! Hacker can access all your information easily or can send any malware to your device.

So, don't let anyone access you phone's settings.

Don't keep NFC unnecessarily ON.

How to use Samsung pay?

In any Samsung device ,you will find one application named Samsung pay.

With the help of that, you can use your smart phone as physical card.We will be able to pay without any internet access too.

When you will open the application Samsung pay, then you have to add your card details.
To add your card details, you can use two methods.
First method- you can take image of your card and by the help OCR technology, you can add your card number.
Second method- manually you can add your card number.
Then you have to add your CVV and validity of the card i.e. month and year. Then after verification your virtual card will get activated.
During paying you just have to open Samsung pay application and you have to select your card and then just tap on the paying machine with your smartphone.
Then it will ask your card's PIN and after providing the PIN, your payment will be successful.

Conclusion

So readers, we have discussed the topics related to NFC. We hope that you have got sufficient information and all your doubts are cleared.

Thanks for reading :)

What is SOC (System on a chip)? What is a Mobile processor?

2020-07-31T20:22:00.000+05:30

What is SOC (System on a chip)? What is a Mobile processor?

Introduction

In this article we would be discussing about a processor and SOC. Both play a very important role in our smartphone. If your smartphone does not have a good SOC or a good processor, then your phone is almost useless.

What is SOC (system on chip)?
What are the components inside SOC?

System on Chip (SOC)

What is SOC (system on chip)?

On a chip, there are various components which are responsible for different tasks. We will now be discussing about those components inside SOC in detail.

1. CPU (Central Processing Unit) --

CPU is also know as processor. It is the brain of SOC.

In the apps, the android code runs by the CPU. CPU is divided into number of cores. That core helps to improve the performance and battery management.

2. GPU (Graphics processing unit) –

It manages all the graphics works, for example:whether you play 2D games or 3D games, all the graphics of the game is managed by GPU.

If you want to play high intensive games with no graphics lag, then, you need a good GPU in your smartphone's SOC.

3. ISP (Image signal processing unit) –

It means when you click a picture, then image sensor gives digital information to the ISP.

The remaining tasks like, noise reduction, sharpening of the image, looking good of a picture, beauty mode, night mode to bright the picture, etc, all these post processing works are done by ISP.

For good looking photos good ISP is very important.

4. DSP (Digital Signal Processor)-

It is like CPU only, but it works at that time when more mathematical calculation work is to be done like calculating gyroscope data. To calculate gyroscope data, more calculation work is need to be done.

Read more: Smart phone battery care tips, tricks and myths.

5. NPU (Neural processing unit)-

AI (Artificial Intelligence) works, are performed by NPU.

Let us take an example:

When you take a picture of a flower, then through AI, smartphones get to know that, it is the picture of a flower.

In some of the camera applications, there is feature of 'age calculator' that is done by NPU.

6. Video E/D( video encoder/decoder) –

The video files are stored in digital format and when we watch a video video E/D converts the digital file to video format.

It helps in converting format. And also helps in decoding of video file.

7. Modem –

The wireless signal which is received by our smartphone is converted into data by the help of modem.

It convert signal to data and vice versa.

There are many types of modems, like 4G, 5G, Wi-Fi, Bluetooth, etc.

The rate at which smartphone sends or receives the signals, depends upon the modem. 5G modem is faster than 4G modem.

What is a mobile processor(CPU)?

In simple language,we can understand it, by its name.

Processor means a device that helps to process the tasks.

The task you perform in your smartphone like, playing games, clicking pictures, watching videos, installing different types of applications, multitasking, all works are handled by the mobile processor.

Let me explain this through an example.

If you compare your smartphone with a car, then, phone’s processor can be compared with the car's engine.

We all know that a car’s engine is the most important part of the car. And we also know that if a car’s engine is excellent, then the car will run smoothly, without any problem.

Similarly, if mobile's processor is new, with good architecture, and latest features, then the phone will run smoothly and fast.

What is a core in a processor?

In simple language, core is a unit of the processor, which works similar as a processor.

Processor's Core

What is the work of cores in a processor?

Let's learn with an example.

A task takes 8 hours to complete. Now you have called one of your friend to help you. Then, I am sure you both will be able to finish the work in 4 hours.

Now imagine, you have called 6 more friends. Then together you all can finish the work in 1 hour.

So, you can compare cores, with you and your friends. More the number of people are present,faster will be the task completed.

Similarly if there are more number of cores in a processor, it will be able to perform the task faster.

Any given task is distributed in the different cores which helps to perform the task faster and in less time.

If there are more numbers of cores in a processor then, less heat is produced.

What is fabrication technology in a processor?

Snapdragon 845 is based on 10 nm (nano-meter) fabrication technology.

Snapdragon 660 is based on 14 nm fabrication technology and Apple Bionic A12 is based on 7 nm fabrication technology.

Before making the processor, its architecture is designed first.

In a processor millions of transistors are used and the size of transistor is measured in nm (nano-meter).

If any processor is based on 10 nm fabrication technology, then it means that the transistor that is used in that processor is of the size 10 nm.

Smaller sized transistors are more powerful. It will use less battery power to perform the task. And it will be considered as a better processor.

What is the Architecture of the processor?

In 95% mobile processors there is architecture of ARM.

ARM processors are sold with license and they allow modification in there terms of service.

Mobile manufacturing companies design the modification of processor's architecture in their own ways.

Some of the designs are-

cortex A5, cortex A11, cortex A53, cortex A59 etc.

Many more designs will launch in the future.

These things may be confusing to you, but in simple language, greater the number better will be the processor.

For example: cortex A53 is a better processor than cortex A11 and cortex A59 is better processor than cortex A53.

What is clock speed or frequency?

Clock speed is measured in GHZ

There is a clock attached with the processor which counts that, how many tasks are performed by the processor in a single second.

If the processor is of 1 GHZ, which means it works 10 crore times in a second.

Higher speed processors are considered as the best processors.

List of popular mobile processors are as follows:-

Snapdragon by Qualcomm
Apple Bionic by Apple
Hisilicon Kirin by Huawei
Mediatek helio
Samsung Exynos by Samsung
Tegra by NVIDIA
Atom by Intel

Conclusion

In the above article, I have tried to explain about SOC and processor in as much simple language as I could. I hope you like it. And I think it will help you next time in buying a new smartphone.

It will also help you to compare the SOCs and select the best SOC and processor for your new phone.
