Unix Tutorial Part 9,Features of Unix Operating System, In this video you will learn different features of Unix operating system. UNIX served as the inspiration for free open-source operating systems such as Linux and FreeBSD, and it is the basis for Apple Inc.’s Mac OS X. Microsoft made this declare at its January event in Redmond. The architecture of Unix operating system is divided by into four layers. Manipulation of the file system 7. Measure the time spent in context switch? Device drivers are the kernel modules that control the operator of peripheral devices. The set of system calls into those that interact with the file subsystem and some system calls interact with the process control subsystem. Features of the UNIX Operating System in Hindi. UNIX was quickly adapted for another computer, and the team ported (modified) it to the PDP-11 by late 1970. Unix, in its initial days, created a significant impact … Advantages and disadvantages of Unix . The first version of SunOS was published in 1982. An operating system is the program that controls all the other parts of a computer system, both the hardware and the software. Assembly language programs may invoke system calls directly without a system call library. In 1969 a team led by computer scientists Ken Thompson and Dennis Ritchie created the first version of UNIX on a PDP-7 minicomputer, which was chosen mainly because of Thompson’s familiarity with the system from his hobby work on it.

After all it is a computer dinosaur with decades of history behind it. By including the development environment, libraries, documents and the portable, modifiable source code for all of these components, in addition to the kernel of an operating system, Unix was a self-contained software system. The Unix operating system is a set of programs that act as a link between the computer and the user. Resource allocation 9.

By operating system, we mean the suite of programs which make the computer work. Handling I/O operations 6. UNIX was developed by AT&T Corporation’s Bell Laboratories in the late 1960s as a result of efforts to create a time-sharing computer system. Multitasking: More than one function can be performed simultaneously by dividing the CPU time intelligently. 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. Full multitasking with protected memory. Different version of Linux are Ubuntu, Linux Mint, RedHot, Solaries, etc. What is Unix ? Unix was considered to be the heart of the operating System.
