Operating systems provide common services and applications to users by managing key computer components and processes. They organize the processor's computing tasks by priority, manage memory allocation to running programs using virtual memory, and allow user interaction through file storage, window switching, pointers, and command line interfaces. Operating systems also facilitate the transfer of power, communication between the motherboard and components, and file management using file allocation tables to track fragmented files across storage. They further secure access to files by controlling permissions for users and limiting actions like transferring or modifying file properties without authorization.

2. What Operating System is?
Operating system is a set of operations and
programs design for a specific purpose. It is
design to provide a user with a common
services and application. Operating system is
a vital component of the system software in
a computer system.

3. Processor management
Processor management is the system by which
the processor’s computing processes are
organised within the operating system. It is
important to divide the tasks up in order of
importance. This is so that things that need doing
straight away will be given the first priority. An
example would be if the computer need to be re-
booted this task would be given priority over
tasks such as playing on a computer game.

4. Memory management
It’s a process in which computer search for a memory to a
programs that are run in the same time.
Virtual memory- it’s a data storage that keeps and separate
the memory addresses accessed before by the user, this
process increase amount of used RAM and transfer data to
the secondary storage.
Virtual memory can have an impact on how well computer
will work because of its amount on the computer storage.

5. USER INTERACTION
To save file on the computer we need to have a storage which
would be a hard drive. After installing an operating system on
the computer we will be able to save and create files easily
there are few ways to save file:
First we click right button on the mouse and press save file
as or we go on open document and we looking for a save as
link.
Also We are able to switch between windows by clicking on
them with the mouse and selecting theme from the source
which would be a start panel. Also we can use pointers, icons
and links to go to the different windows.
Command line interface is a panel in which we write a
commands and the operating system fallow them and make
sure that does commands are done.

6. Components communication
Transferring power- power is needed to run the computer
and its transferred from one location to the other
BIOS- its check if any computer system(hardware, software)
is connected to the computer if not it gives an information
about it and the user is able to fix that problem.
Connection between motherboard and the computer- that
connection allow the mother board to track down all the
computer interfaces and computer actions also its works like
a brain of the computer.

7. File Management
File Allocation Table- It’s a table that locates any data on
a computer, if computer went through fragmentation files
may be divided and allocate all around computer FAT
keep a track of them.

8. Securing files
Access to the file- the people who are allow to access this
file are:
Me, College stuff and teachers.
We can I do with this file?
There are many things I am able to do with this file for
example:
I can scan this file, I can locate and open it in different
programs also I can make a copy of it and save it on my
hard drive and I can delete this file from my computer.
Things I can’t do with the file
are I can’t transfer it on to a
cd, I can’t change its
properties.
