Input Devices

An input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing.

The devices that are used to enter data and instructions into the computer are called input devices.
There are many types of input devices such as:

Mouse

Mouse is an input device that looks a little bit a mouse. It has a ball on its underside that is rolled on a flat surface or mouse pad. It also has button on its top which communicates certain commands to the computer while pressed.

Mouse Events:

Mouse events refers to the activity that can be performed by using the mouse, a typically mouse can perform the followings events.

Right Click:

It is used to view properties of an object such as file, folder, desktop etc.

Drag:

When you keep on pressing the left mouse button while moving the mouse this event to move to select more than one item at a time.

Keyboard

The keyboard looks like a typewriter keypad to which some special keys has been added. The keys normally available on the keyboards are Numeric, Alphabetic Functions and additional Special-Purpose keys. This standard keyboard is also called “QWERTY”.

Function Keys:

The function keys are an easy way to give certain commands to the computer. The particular software we use defines what each function key does.

Main Keyboard:

The main keyboard includes the familiar keys found on a typewriter keypad, as well as some special command keys.

Numeric Keys:

The numeric keys serve one of the two purposes depending on the status of the Num lock key. When the computer is in the Num lock mode these keys can be used to enter numeric data and mathematical symbols (/ for “divided” by”, * for “multiplied by”, - for “subtraction” and + for “addition”)

Keyboard has divided four parts

Track Ball

A track ball is also a pointing input device it performs functions like a mouse but it is a stationary device. it has a moveable ball on its top. The ball is rotated or rolled with fingers to control the moment of pointer on the screen. Like mouse, a track ball also has button used to send the commands to computer.

Joy Stick

Joy stick is also pointing device it consist of a vertical handle like a gearshift lever mounted on a base. The vertical handle is used to control the moment of pointer on the screen. It also consists of one or buttons. The buttons of the joy stick is pressed to activate certain events or actions. Joy stick is basically used to play video games. It is also used in some computer aided design (CAD) system.

Light Pen

The light pen is a handle pointing input device. It is a light sensitive styles or pen like device. It is connected with the computer by a wire. When the front and of the pen is touched with the monitor screen, the photo cell detects or sense a position on display screen. This device also has a button. The user points the objects to be selected on the display screen and then presses a button on the light pen.

A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with the computer's CRT TV set or monitor. It allows the user to point to displayed objects, or draw on the screen, in a similar way to a touch screen but with greater positional accuracy. A light pen can work with any CRT-based display, but not with LCD screens, projectors and other display devices.

Digital Camera

A digital camera is an input device because it captures information and stores it on the device via the memory card (which is a storage device).

A digital camera is an input device. It is used to take pictures in digital forms. It does not use traditional camera film. It uses a light sensitive processor chip to capture photographer image in digital form. These images are stored on a small diskette inserted in the camera or on flash memory chip.

Touch Pad

Touch pad is a pressure sensitive pointing input device. Touch pad is also known as track pad. It is also stationary device like track ball but it has no moving parts. It is a small, flat surface over which we slide our finger tip to move the pointer on screen for pointing desired icons. As we slide our finger tip on the flat surface of touch pad the pointer moves on the screen. Touch pad have one or more button.

Windows 7 vs Windows Vista

2011-07-29T17:18:00.014+05:00

here it is. The October 22 will be launched officially Windows 7 , the new operating system Microsoft , the supposed panacea of the American giant in front of his unfortunate

(Mis-managed) Windows Vista.

Well, let’s go by parts.

Vista, also known as the antichrist of the computer or the wrong horse (it will be so slow went it in full capacity), provoked a barrage of criticism pointed to two basic form of touch noses to the user

1. Slowdown of applications and the operating system

2. Compatibility issues with certain drivers and program

asically both of these operating system is very easy and user friendly. Windows Vista is an older version of Microsoft windows as compare to Windows 7. Windows 7 is very fast, reliable and secure as compare to Vista. Its provide lots of functions and utility programs. No required any Antivirus because it has a powerful defender. This is the main reason that window 7 is popular then Vista.

First of all you have to need a power full computer system if you want and interested to use any one of this operating system. Then your pc has an ability to store and run this OS (Operating System) easily. Because every operating system have some own requirements.

Power full computer mean power full accessories like Processor, RAM, Cash, Storage Media...etc

SOLUTION in WINDOWS 7

perating System: You can tell a lot about a computer by checking the version of Windows 7 that’s installed on it. First, check whether the PC has a 32- or 64-bit version of Windows 7. The 32-bit version is fine for most needs and may be best if you have older 32-bit hardware or software you want to use. If you’re looking for a performance boost or starting from scratch, lean toward a PC that runs the 64-bit version of Windows. The 64-bit PCs and software handle larger amounts of memory (4GB and higher).

All computers that have the Windows 7 Compatible logo can run either the 32- or 64-bit version.

AM: 1GB will get you by. I recommend at least 2GB for most users and 4GB for serious media, entertainment, and gaming junkies. If the PC comes with the 32-bit version of Windows, don’t bother with more than 4GB.

Type and speed: Look for DDR2 or DDR3 SD RAM and compare speeds, measured in gigabytes. DDR stands for “double data rate,” and SD RAM stands for “synchronous dynamic random access memory.” Just remember that DDR2 is good, DDR3 is better, and higher speed translates into better performance and higher cost.

ard Drive: The computer’s hard drive is a disk inside the computer that stores data permanently; When comparing hard drives in different PCs, consider the following factors:

Storage capacity: Size or storage capacity is measured in gigabytes. 250GB is usually more than enough. Photographers, video graphics, serious gamers, and game designers require more space—at least 500GB.

Note:

his is the sign of Genuine windows if your window does not appear this sign its mean your windows is not genuine. You can’t use the programs and functions properly, you can use all functions and utilities when your windows is genuine otherwise your window will not working properly whether your windows is 7 or Vista.

So before the installation conform it that your windows is genuine which you’re installing in your PC and rechecked after the installation that your windows is genuine or not.

This sign is appeared in the properties of My Computer.

1. Right click on My Computer

2. Select the properties
