What are the Characteristics of the UNIX Operating System?

UNIX is an operating system created in the 1960s and has constantly improved. The operating system is a set of programs that allows the computer to function properly. UNIX is a stable, multitasking server operating system that works on any platform, including desktop and laptop computers. In this section, we will look at What are the Characteristics of the UNIX Operating System.

What is the UNIX Operating System?

UNIX is a modular operating system composed of several essential components, such as the kernel, file system, shell, and a core set of utilities or programmes. The kernel is a master control programme that provides services to start and stop programmes and is at the heart of the UNIX operating system.

Characteristics of the UNIX Operating System

Here are some of the main characteristics of the UNIX Operating System,

• Multitasking

The UNIX operating system enables you to run multiple tasks from the same terminal, with one task running in the foreground and the other in the background.

• Multitask

The UNIX operating system allows multiple users to access computer resources such as main memory, hard discs, tape drives, etc. Multiple users can access the system from different terminals and run various tasks that share the resources of a command terminal. It is concerned with the time-sharing principle. A scheduler divides the CPU time into several segments, also known as time slices, and assigns each segment to each user on a scheduled basis.

• Portability

This feature allows UNIX to run on various machines and platforms, allowing for the easy transfer of code to any computer system. Because a large portion of UNIX is written in C, and only a tiny portion is coded in assembly language for specific hardware.

• File Security and Protection

As a multi-user system, UNIX places a premium on file and system security. UNIX security levels include assigning usernames and passwords to individual users to ensure authentication, providing access permissions such as read, write, and execute, and finally, file encryption to convert the file into an unreadable format.

• Command Structure

UNIX commands are simple to learn and use. In the UNIX operating system, commands are case-sensitive and are typically written in lowercase. Eg: mv, cp etc.

• Accounting

UNIX keeps track of the tasks that the user creates. This feature improves system performance by monitoring CPU usage and checking disc space. It allows you to keep track of how much disc space each user uses, and the disc space can be limited by each other. You can set a different disc quota for each user. The root user can perform these accounting tasks using various commands such as quota, df, du, and so on.
