Greetings
Hey 😊 Everyone How are you all .I wish all of you are happy and enjoy your work.
Today I will tell you about Unix Operating System.
UNIX operating system
UNIX is a Powerful Operation Program developed by Ken Thompson, Dennis Ritchie at AT&T Bell laboratories in the 1970s. It is popular among science, engineering, and educational institutions because of its highly acclaimed features such as versatility, flexibility, and much more. At UNIX, a file system is a sequence of files and directories where users can store and retrieve information using files.

UNIX operating system features:
Let's discuss the features of each UNIX OS in detail.
Features of using Unix Operating System
The UNIX operating system is a multi-tasking app that allows you to run more than one task from the same terminal so that one task can be done as a priority and another task as a background process.
Multiple users:
The UNIX application supports more than one user to access computer resources such as memory, hard disk, tape drive, etc. Many users can log into the system from different terminals and run various tasks that share command functions. Airport. It is about the principle of time sharing. Time sharing is done by a timer that divides the CPU time into several segments and is also called a fraction of the time and each component is assigned to each user on a fixed basis. This time is limited. When this time expires, we transfer control to the next user in the system. Each user performs his or her own set of instructions over a period of time.
Portability:
This feature enables UNIX to run on various machines and platforms by easily transferring code to any computer system. As a significant part of UNIX is written in language C, and only a small portion is coded in the compiling language of certain computer systems.
File Security and Protection:
As a multi-user system, UNIX specializes in file and system security considerations. UNIX has different levels of security using the allocation of a username and password for individual users to ensure authentication, at a level that gives access to the file namely. read, write and rewrite file encryption to convert the file into an unreadable format.
Command Structure:
UNIX commands are easy to understand and easy to use. Example: "cp", mv etc. While operating in the UNIX area, UNIX commands are very sensitive and written in small capital letters.
Communication:
At UNIX, communication is an excellent feature that enables the user to communicate globally. Supports various communication resources provided using writing command, postal command, speech command, etc.
Open Source:
The UNIX operating system is open source means it is free for all and a community development project.
Accounting:
UNIX maintains an account of user-created activities. This feature improves system performance by monitoring CPU and disk space monitoring. Allows you to save the disk space account used by each user, and disk space can be limited to each other. You can assign each user a different disk share. The root user can perform these calculation tasks using various commands such as quota, df, du, etc.
I would like to say special thanks to Sir
