this is a complex of interconnected system
programs that are loaded when the computer is
turned on and are constantly stored in the
computer's memory. They conduct a dialogue
with the user, manage the computer, its resources
(RAM, disk space, etc.), run other (application)
programs for execution. The operating system
provides the user and application programs with a
convenient way to communicate (interface) with
computer devices.

3. OPERATING SYSTEM FUNCTIONS :

• Data exchange between the computer and
various peripheral devices (terminals, printers,
floppy disks, hard disks, etc.). This data
exchange is called "data input/output".
• Providing a system for organizing and storing
files.
• Loading programs into memory and ensuring
their execution. organization of a dialogue with
the user.

4. OPERATING SYSTEM STRUCTURE

• BASE module (OS kernel) — manages the program
and the file system, provides access to it and file
exchange between peripheral devices;
• Processor command — decrypts and executes user
commands, which mostly come from the keyboard
• Drivers of peripheral devices — the software ensures
the operation of these devices with the processor
• Additional utilities — will make the process of
communicating with the computer convenient and
universal.

5. KERNEL -

part of the operating system:
• permanently located in RAM;
• managing the entire operating system;
• containing:
• device drivers, memory management routines,
task scheduler; implementing system calls,
etc.

6. DRIVER –

• a computer program by which the
operating system gets access to the
hardware of some device.
• In general, a driver is required to use
any device (both external and internal).

7. Interface–

INTERFACE–
• hardware and software tools that provide
graphical display and exchange of
information between a person and a
computer.

these systems for their high flexibility and reliability.
Mac OS X is the best option for people who want to
work on a computer without delving into the specifics
of the system.
