1- Computer Components
All computers consist of Tow parts:
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.
Which is any set of machine-readable instructions that
directs a computer's processor to perform specific
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
2- Computer Operating System
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,
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.
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
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
• Running too many applications at the
same time leads to consuming hardware
resources, and we should close the
• Add more or Replace your old RAM to
Increase its capacity.
• If the HDD free space is small try to buy a
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.
• Again we should close All finished
applications, to reduces the CPU
• Use Virus & spyware protection software
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.
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.
• 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
• Using cleaner applications which clean
your HDD from Application Leftovers,
Trashes, Cache Files, Logs, History files
to speed up your computer.
