The main difference between Linux and Unix is Linux is a clone of Unix; When we compare Unix to Linux, Linux default shell is BASH while the Unix shell is Bourne Shell. UNIX (and Linux by extension) systems offer the following features: Fully protected multitasking: This means that UNIX can easily switch between tasks without the operating system crashing, because all UNIX processes are separate from those of the operating system. By operating system, we mean the suite of programs which make the computer work. It consists of three parts: Kernal, Shell and Programs. The main focus that was brought by the developers in this operating system was the Kernel. Shell: The shell is the utility that processes your requests. Unix is a copyrighted name and IBM AIX, HP-UX and Sun Solaris are only Unix operating system remained till date. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops. Introduction to Linux UNIX Unix is a multi-user, multi-tasking operating system. Kernel is a set of routines mostly written in C language. Here, we will work with these commands interactively from a Unix terminal. Unix and the C were found by AT&T and distributed to government and academic institutions, which led to both being ported to a wider variety of machine families than any other operating system. This tutorial gives an initial push to start you with UNIX. Most of the Unix and Linux commands are similar in nature. This tutorial has been designed for everyone interested in learning the data exchange features of Unix Sockets. Kernel Shell In simple words you can say – Kernal – interacts with the machine’s hardware Shell – interacts with the user The Kernel: The kernel of UNIX is the hub (or core) of the UNIX operating system. UNIX is an operating system which was first developed in the 1960s, and has been under constant development ever since. It is an commercial OS. There are two important divisions in UNIX operating system architecture. Unix was originated around in 1969 at AT&T Bell Labs by Ken Thompson and Dennis Ritchie. You can have many users logged into a system simultaneously, each running many programs. Multiuser: A multi-user Operating system allows more than one user to share the same computer system at the same time. In this tutorial, you will be able to understand the basic concepts of operating systems, features of Unix, along with its Architecture. Linux is the clone of Unix. Unix is also an operating system like Linux. Linux. Prerequisites Learning Sockets is not at all a difficult task. Unix ppt 1. Multi-Tasking: More than one program can be run at a time. Tutorials Point, Simply Easy Learning 2 | P a g e The main concept that unites all versions of UNIX is the following four basics: Kernel: The kernel is the heart of the operating system. Difference between Linux and Unix Tutorials Point, Simply Easy Learning 1 | P a g e UML Tutorial Tutorialspoint.com UNIX is a computer Operating System which is capable of handling activities from multiple users at the same time. Our Linux tutorial includes all topics of Linux OS such as Linux commands, Directories, Files, Man Pages, File Contents, File Permissions, shells, VI editor etc. UNIX OS was created in the late 1960s at AT&T Bell Labs whereas Linux is an operating system built by Linus Torvalds at the University of Helsinki in 1991. UNIX Introduction What is UNIX? Open System: The UNIX is open source code i.e Any user can modify Unix open-source code according to there ideas and requirements Introduction to Unix Operating System: Let’s start with Tutorial #1: ‘What is Unix’ in this series. The main concept of multitasking is maximum utilizing CPU resources. Before Linux and Windows, computer world was dominated by Unix. It interacts with hardware and most of the tasks like memory management, tash scheduling and file management. We assume that you are well versed with the basic concepts of C programming. Unix was considered to be the heart of the operating System. A Unix terminal is a graphical program that provides a command-line interface using a shell program. Unix commands are inbuilt programs that can be invoked in multiple ways. It has several features similar to Unix, still have some key differences. In this tutorial, you will learn different basic and advanced Unix Commands.
