General knowledge...Refresh your mind

Computer Basic

2012-01-11T09:56:00.000-08:00

Good evening friends,
First of all i am really very sorry for not showing any new post since long time.As in this blog i want to provide you some general knowledge tips so in this post i want to share computer basic knowledge which necessary in any qualifying exam.
Friends,
Charles Babbage was the father of computer.Thare are basically five generation of computer.first computer was very big as room size which use vacuum tube.After this ic chips ,then transistors comes in existence.As development grow the size of computer reduces as efficiency increase.Now l.c.d,laptop,notebook comes in market.Computer has basically three main parts:-
1.Output unit:-It is also called visual display unit.It is used to show output to user.Monitor,printer are example of it.

2. Central processing unit:-it is also called brain of computer.It also contain memory unit,arithmetic and logical unit and control unit.

Input unit:-It takes input from your for showing output.Ex .keyboard ,mouse,joystick etc.
Now our concern is on that is computer is a hardware or software?
Friends,computer system by just seeing is a hardware like c.p.u,u.p.s,moniter ,speakers ,printer etc but set if program which helps in operate machine called software.Hardware can be touched but software can't.Hardware can be damaged or destroy but software only obslete means new advancement in technology can replace old one.If we want to set two system then for each system ti be setup require different hardware but same software can be coppied into different system.Computer understand binary language of 0,1.For understanding it four number system require:-
1.Binary number system
2.Octal number system.
3.Hexadecimal number system.
4.Decimal number system.
We will discuss number system basics in next post.

Blood .........An essential component of body.

2011-07-17T22:57:00.001-07:00

This article is about blood.As we all know blood is very essential for existence of life.So we should aware about it.

Friends,
Blood is made up of blood plasma and its cells floating in blood plasma.In blood lifeless plasma present 65% and live cells present 35%.Plasma contains 90% water and 10% other matters.
Blood Group
In 1902 a nobel price winner karl landsteiner discover blood groups.There are four type of blood groups in human body.

Blood group A

Blood group B

Blood group AB

Blood group O

A person having blood group O can donate blood to everyone,that is why it is called universal donar and having blood group AB can takes blood from every person so it is called universal recipient.

Blood group	Blood recipient group	Blood donation group
A	A,AB	A,O
B	B,AB	B,O
AB	AB	A,B,O,AB
O	O	A,B,AB,O

RH factor
It is a type of antigen which is found in red blood cells.If this factor found in a person body then he is RH⁺ and otherwise he is RH^-.In India 97% people are RH⁺.If a person having RH⁺ donate blood to a person having RH^- then that person might be dead.
Red blood cells and White blood cells
Red blood cells
These cells are red in color due to presence of red pigment called heimoglobin.Heimoglobin Supply Oxigen to every cell and extract CO₂ from body.The life span of RBC is 120 days.These are formed in bone marrow.
White blood cells.
These cells are unstructured in shape.Its life span is small as compared to RBC.Its life span is 24 to 30 hours.These are also formed in bone marrow.It main function is to separate dead components from body and transfer of blood and prevent body from infectious diseases.
Friends,
I hope you will enjoy the article by getting useful knowledge from this.
Thank you.

Oxidation and Reduction

2011-07-11T21:34:00.000-07:00

This article is about Oxidation and Reduction reaction.Before discuss about the blog we should know something about its main point .

Oxidation and Reduction

Points To Remember:

The Energy which we get in our body is a result of redox reaction.

Reduction and Oxidation reaction takes place simultaneously.Where there is oxidation then equal amount of reduction also takes place.In combine form these are called redox reaction.

Electrolysis is also redox reaction where oxidation takes place at anode and reduction takes place at cathode.

The lose of electron by an atom or molecule or ion is called oxidation and gain of electron is called reduction.

Oxidation nature of an atom is directly proportional to electro nagetivity.

Terms	Change in oxidation Numbers	change in electron
oxidation	Increases	Loss of electron
reduction	Decreases	Gain of electron
Oxidising Agent	Decrease	Accepts electron
Redusing agent	Increase	Donates electrons
substance oxidised	Increase	Loses electron
Substance redused	Decrease	Gains electron

Questions on topic
Ques 1:-Oxidation involves?Ans. Loss of electron.

Ques 2:- A redusing agent is a substance which can..?
Ans. Donate electron.

Ques 3:-The oxidation state of nitrogen varies from ..?
Ans. -3 to +5

Ques 4:- Up to which product water can be oxidised..?

2011-07-09T07:49:00.000-07:00

This article is about Maths tricks for finding square of a number.It is not tough task to find square of a number but how fast we compute its value is a major consideration.
In this article i will discuss about some tricks for easy computation.
A logo to manage squares:

Friends,

Problem 1: What is square of number 10001?
Solution: For this type of number which is start from 1 and end by 1 and zeroes in between.
step:- Write 1 at first and at end and makes double the zeroes.
Square of 10001 is=10000001

Problem 2: What is square of number 10101?
solution:
Step 1: For this type of problem count the numbers of 1's.
Step2: Write from 1 to (number of 1's) and then reverse upto again 1 occurs and placed zero in between every digit.
Ex. square of 10101=?
step 1:Count number of 1's=3
step 2:Write from 1 to 3 and zero in between and reverse upto again 1 occurs
102030201

Problem 3:How to calculate 4²+5²+(4*5)²?
solution:For this type of problem when two number are continuous and third in its multiplication then ans is square of one greater then third number.
Ex.4 is first number and 5 is second number and 4*5 is third number then we can write it as:
4²+5²+20²=21²
we can say that the ans is=21²=441

Problem 4: How to calculate integers between square of two continuous numbers?
solution: Let two continuous numbers 6 and 7
Integers between 6² and 7²=?
We can calculate it by just add these two numbers and subtract 1 i,s 6+7-1=12
36 37 38 39 40 41 42 43 44 45 46 47 48 49

Problem 5: how can we add series of type 1+3+5+7+9
solution:
STEP 1:Count numbers.
Step 2:Find mid number and calculate its square.
If number is odd it is easy to calculate mid and when number is even then find average of two mids.
Ex. Add 1+3+5+7+9
step 1: numbers are 5.
step 2: 5 is mid number so ans is 5²=25
Ex2. When add 1+3+5+7+9+11=?
step 1: Numbers are 6.
step 2: Average of 5 and 7 is (5+7)/2=6 so ans is 6²=36
