Operating Systems-Page 4
This lab complements the operating systems course. With this course Students are able to: COB 1.Implement practical experience with designing and implementing concepts of operating systems COB 2: write the code to implement and modify various concepts in Operating Systems using Linux environment.
operating system is responsible for providing access to these system resources. The abstract view of the components of a computer system and the positioning of OS is shown in the Figure 1.2. Task “Operating system is a hardware or software”. Discuss. 1.2 History of Computer Operating Systems Early computers lacked any form of operating system.
The oldest of all Microsoft's operating systems is MS-DOS (Microsoft Disk Operating System). MS-DOS is a text-based operating system. Users have to type commands rather than use the more friendly graphical user interfaces (GUI's) available today. Despite its very basic appearance, MS-DOS is a very powerful operating system. There are many .
OPERATING SYSTEMS It is not enough to have a good mind; the important thing is to use it well. 7 Clustered Systems These systems consist of two or more systems coupled together (Figure 1.7). These systems share storage & closely linked via LAN. Advantage: 1. Used to provide high-availability service.

The operating system uses CPU scheduling and multiprogramming to provide each user with a small portion of a time. Computer systems that were designed primarily as batch systems have been modified to time-sharing systems. Advantages of Timesharing operating systems are as follows: Provides the advantage of quick response

Computer Systems: Software Operating Systems Operating systems can also be categorized as single user or multi-user. - A single user operating system allows only one user to operate the computer at a time. - Multi-user systems allow several users to run programs and operate the computer at once.

In brief, UNIX provides a buffer pool whose size is set when Communications of the ACM the operating system is compiled.
