Defregmentation and compressed folders .

Defragmentation

The disk defregmentor (defrag) rearranges the files and free space on your disk so that you can open files more quickly , because they are stored in adjacent units and so free space will be consolidated .
To start Defrag you just go on start , programs , accessories , system tools and disk defragmentor .
You choose the drive you want to defrag and apply the defrag on . If you change your mind you can stop the defrag or pause it and even show more details if you would like .

Compressed Folders

Folders are compressed using the zipped folders feature . They use less space and can be transferred to other computers more quickly . Once you have created the compressed folder you can compress files by just dragging what you want directly to the folder .
You can create a zipped folder by opening my computer , double click on the drive , on the file menu press new and click compressed folder . You name it then press enter

Main components of a computer

The Computer On The Inside

The central processing unit (CPU) and the main memory are chips that can be found clipped to the mother board in the system unit .

The CPU is the processor of the computer , it is the brain where all the system combines together . The CPU measures also the speed of your computer mostly in Mhz or Ghz .

The main memory is the primary storage of the computer . It stores the data and instructions that are held  there for use of the CPU .

The backing storage is where you store amounts of data outside of the main storage .You must have at least one form of backing storage.

What is a bus ?

A set of parallel connecting to two or more units forms what we call a bus . A bus is a data roadway along which data and commands travel .The greater the capacity of the bus is the more speed the computer will have .

In a computer we have three types of buses :
    -The address bus
    -The data bus
    -The control bus .

The Computer System

When we talk to our friends , families and also strangers , we just refer to the words 'data' and 'information' as the same thing . But it's not , in fact it really is this :

                       Data + Structure = Information

The computer will process data , add the structure and give us information .

What is a computer ?

A computer is a machine which can be programmed to accept the data we put in and gives out information .

                       Input - Process - Output 

We put our data in the computer (input) , then the machine will process it ,finally information comes out
(output).

So we can just say that a compute is a device that accepts input , processes data ,stores data and produces output .

Input is the process of entering data in the computer .Some examples used for inputting data are the keyboard , mouse and the modem.

Output is getting processed data out of the computer . Either the computer will display the data on the monitor screen which we call soft copy  or either sends the data to a printer and we call that hard copy.
