How Computer works?
1- Computer Components

• All computers consist of Tow parts
• 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.
• Software.Which is any set of machine-readable
  instructions that directs a computer's processor
  to perform specific operations.

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
  programs.

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.

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 exampleRAM 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.

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.

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
  applications.

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 memory.
• Then your computer will suffer and become so slow
  waiting to finish some jobs to free some small
  space to the next job.

11
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.

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.

13
Fix the busy CPU

• Again we should close All finished applications,
  to reduces the CPU consumption .
• Use Virus spyware protection software and
  cleaner.

14
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.

15
Why computer becomes slow by the time?

• Every application we install adding more files to
  the OS and store additional setting to the
  system.
• 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.

16
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 originals.

17
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.
