Personal Computer basics

Personal Computer how it works?

Personal computer is one of the greatest invention man ever made. Do you know how a computer works? How about its internal parts? All of these are discussed in my very first blog.

Personal Computer

Desktop computer or laptop computer are digital in nature. Computer process  bits of information by interpreting our action into one’s and zero’s.   When we use a word processor like Microsoft Office our character or letters has a corresponding 1′s and 0′s. These numbers are what we call binary numbers.  We as human communicate in a different language. To be exact we use the decimal number system.
Here is an example of binary number system and its equivalent to decimal number system.

Decimal         Binary

          0                0

          1                1

          2               10

          3               11

          4              100

          5              101

          6              110

          7              111

          8             1000

          9             1001

From the table above 0 to human language means 0 also to the

personal computer system.  Next is 1, which is equivalent to 

one also the binary system, then number two to human language

is different to personal  computer number system.   It is 

now equivalent to 10, then number  three is  equivalent to 11

and so on and so forth. So much for that I will tackle a more

deeper understanding in my future blogs.

What will happen now to the numbers and letters we type to

computer is processed inside the computer.  The motherboard 

has a processor which manipulate data and convert it to 

streams of 1's and 0's that is Understood by our personal

computer.   When we are using a word

processor,  these data are temporarily stored in the memories

and finally save it to our hard drive. If we have 60 gigabytes 

of hard disk, it means we can store 60gb of 1's and 0's into our

personal computer.

What we need to learn about personal computers as a 

Technician or a user is it has four basic functions. 

These are input, processing,  output, storage. When we

say input, we talk about ways we can encode the data to 

our personal computer.  Basically they are keyboard, mouse,

touch screen, microphone, etc.  When data is encoded to

the computer it is time to process it by the microprocessor

in the Motherboard.   Once we are through we can now output

the data by means of printing it to a paper, monitor, or

speaker as sound, finally for safe keeping of

data we can store it to the hard drive, CD ROM, flash disk,

diskette, etc.

That is for now have a great day.
