An operating system is a
set of programs that
enable a computer or
other device to operate
and the user to interact
with it. Any computer
consists of two groups of
components: hardware
and software

The OS performs many functions:
creates a user-friendly interface; standardises
access to input and output devicescoordinates
resource allocation between running software;
fixes errors and debugs them; provides
multitasking of programs;

Components of an operating system. The operating
system is a multi-layered structure with the kernel at
its centre. Drivers and services are located on top of
it, and the user interface acts as the shell.

Windows
Windows has Availability Quantity of software.
Thousands of interesting and useful applications
and games are created for the platform every
year. Quality support for entertainment software.
Support for specific software. But Windows is
not distinguished by the security system - the OS
of this family is often affected by viruses and
spies. They work unstably, but are regularly
updated. But the graphical component here is at
the height. It is a great option for beginners.

MacOS
Tabile and secure; has an impressive
package of unique software; is part of
the Apple ecosystem; has iCloud.
In order to use macOS, you'll have to
splurge. It's an operating system aimed
primarily at work - there are critically
few games for it. Another disadvantage
is that it has little business use.

Linux
The advantages of Linux include:- community
support;- versatility;- accessibility;- speed of
operation;- level of security.It is not compatible with
Windows. And in order to use Linux, you need to
master the terminal - only in this way you will be able
to provide full control. There is a graphical interface
here, but it does not allow you to unlock the full
potential. It is also noted that most equipment
(especially old equipment) is not compatible with
Linux.
