How Computer works?

1- Computer Components

All computers consist of Tow parts:

1. Hardware.

Which is the physical parts or components of a

computer, such as the monitor, mouse, keyboard,

computer data storage, hard disk drive (HDD), graphic

cards, sound cards, memory, motherboard, and so on,

all of which are physical objects that are tangible.

2. Software.

Which is any set of machine-readable instructions that

directs a computer's processor to perform specific



How Computer works?

2- Computer Operating System

• Computer Hardware and software need

an operating system. Such as Windows,

Linux, MAC OS.

• An operating system (OS) is system

software that manages computer

hardware and software resources and

provides common services for computer



How Computer works?

2- Computer Operating System


How Computer works?

3- Running Applications

• All Application software stored in hard

disk drive (HDD).

• When user request to run any application

the central processing unit (CPU) reads

all stored data from HDD and put them

into random access memory (RAM) then

start process them.


How Computer works?

4- Using RAM

CPU prefer to use RAM because it is much

more faster than HDD.

But RAM is a small temporary storage capacity,

for example

RAM is 8G but HDD more than 1000G.

Because the limit storage of RAM, OS always

free RAM from the finished closed application to

reuse this space with new applications.


How Computer works?

5- Insufficient RAM space !

But what if you want to run more applications at

the same time and there is not enough space

left in RAM to hold the new data.

OS will solve the insufficient RAM space to run

more application by reserving some free space

found in HDD as a virtual memory and start

using it beside the real RAM.


How Computer works?

6- Using virtual memory on hard disk drive HDD

But HDD is slower than RAM, so using virtual

memory from HDD will slow the processing of



How Computer works?

6- Insufficient RAM and HDD space !

• But what if your HDD is almost full and

there is not enough space for virtual


• Then your computer will suffer and

become so slow waiting to finish some

jobs to free some small space to the next



Fix the RAM and HDD problem

• Running too many applications at the

same time leads to consuming hardware

resources, and we should close the

finished applications.

• Add more or Replace your old RAM to

Increase its capacity.

• If the HDD free space is small try to buy a

big one.


How Computer works?

7- CPU always busy.

What if there is some hidden programs always

run in our computer, spying on us or stealing

our sensitive data, sure these programs will not

finish and will make the CPU always busy.


Fix the busy CPU

• Again we should close All finished

applications, to reduces the CPU


• Use Virus & spyware protection software

and cleaner.


Why computer becomes slow

by the time?

Every new computer start works fine and fast, there is

no problem, but by time they become slow, Why?

By time all new applications require more hardware

resources such as fast processor more HDD storage

space and RAM space, and that will make our current

computer to be slow.

When we using our computers most of our application

stores settings, history logs, temporary files, update

their files with new versions, add more packages from

internet and so on, so they always become bigger.


Why computer becomes slow

by the time?

Every application we install adding more files to

the OS and store additional setting to the


So when we startup our computer it needs more

time to load the new files and new setting

added to the system.

Even when we uninstall them, some of their

settings and temporary log files stay in HDD.


Fix the File Increasing

• Install only the needed applications.

• Clean and delete all unnecessary files

including old files from your HDD or move

old files to external drives and delete the



Fix the File Increasing

• Using cleaner applications which clean

your HDD from Application Leftovers,

Trashes, Cache Files, Logs, History files

to speed up your computer.
