1. Introduction: An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs usually require an operating system to function. For any computer to function‚ it must have an operating system (OS). A powered computer with no operating system will only display coded text messages only understandable to the computer

Operating system virtualization is a method of altering a standard operating system so it may handle multiple users all at the same time. These individual users would not have any interaction with one another. Their information would also remain separate‚ even though they are using the same system. While this technology has several uses‚ the most common uses are in hosting situations and server consoladation. With operating system virtualazation‚ a single system is set up to operate like several

1. In a multiprogramming and time sharing environment‚ several users share the system simultaneously. This situation can results in various security problems. a. What are the two such problems? Ans: The two problems in Multiprogramming and time sharing environment are Stealing or copying a user’s files; Writing over another program’s (belonging to another user or to the OS) area in memory; Using system resources (CPU‚ disk space) without proper accounting; Causing the printer to mix output by

A History of Operating Systems To understand and to be prepared for the future of computer support it helps to know the history of operating systems. The operating system is the software that links the user to the computer’s hardware. Early mainframes (the predecessor of the personal computer) did not use an operating system. Programs were loaded onto the mainframe by paper punch cards‚ magnetic or paper tape. The user would start the program and wait for the program to complete‚ or crash

History of Operating Systems Early computers lacked any form of operating system. The user had sole use of the machine; he would arrive at the machine armed with his program and data‚ often on punched paper tape. The program would be loaded into the machine‚ and the machine set to work‚ until the program stopped‚ or maybe more likely‚ crashed. Programs could generally be debugged via a front panel using switches and lights; it is said that Alan Turing was a master of this on the early Manchester

Networking in Operating Systems Week 6 Check Point Networking in an operating system can be a daunting task is the User doesn’t know what they are doing. There are many advantages to networking. Sharing of data and resources can help to make a company run smoothly and more efficiently. How this happens is the connection of a workstation to a network. While a network is a group of computers attached to a wire‚ it has become much more complicated. The wire or connection is there for

Can traps be generated intentionally by a user program? If so‚ for what purpose? (Chapter 1) Interrupt is that causes a computer processor to temporarily stop executing its current program and execute another program instead‚ finally returning control to the original program. So it prevent that more important task
