1. Briefly, what is an operating system? An operating system serves as a hardware/software interface, acts as a repository for common, shared routines and defines a platform for constructing and executing application software. 2. An operating system presents an application programmer with a relatively "friendly" hardware/software interface. What does this mean? Why is it important? The user interface, sometimes called the shell, provides a mechanism for the user and application programs to...

An operating system is the program that manages all the application programs in a computer system. This also includes managing the input and output devices, and assigning system resources.

Operating systems evolved as the solution to the problems that were evident in early computer systems, and coincide with the changing computer systems. Three cycles are clear in the evolution of computers, the mainframe computers, minicomputers and microcomputers, and each of these stages influenced...

1.5 Modern OS are interrupt driven. Events are almost signaled by the occurrence of an interrupt or a trap, which caused either by an error or by a specific request from a user program that an OS service be performed .Dual-mode Operation allows OS to protect itself and other system components whereas Multimode Operation increasingly CPUs support multi-mode operations. System call provides the means for a user program to ask OS to perform OS tasks on the user program’s behalf. When a system...

1 INTRODUCTION The hard disk is a magnetic disk used typically to record and store information, whenever we save data or install a program on a computer. The information stored in the hard disk does not get deleted when the computer is turned off. Disk partitioning is the process of dividing the hard disk data storage space into separate areas called partitions. Disk partitions will usually take place or get created the first time the hard disk is prepared for usage. After the disk has...

Operating Systems Task 1 An operating system (OS) is a part of software which manages the operation of a computer. It controls the hardware and software of a computer, without it a computer would be useless. DOS Disk operating system (DOS) was released in 1981. It will load from a floppy disk each time a computer starts. DOS uses a command line interface. Command line interface can be difficult to use if you aren’t trained or experienced in using it. DOS is the predecessor to windows. DOS...

File Systems The file system provides the environment for working with files and folders. Windows uses FAT12, FAT16, FAT32 and/or NTFS with NTFS almost always being the best choice. Linux also has a number of its own native file systems. The default file system for Linux used to be ext2, now it is typically ext3. MS-DOS used to be and Microsoft Windows continues to be the most popular operating system for 80386, 80486, and Pentium PCs. Because Linux started on 80386/80486 PCs, a...

Memory management in multiple operating systems An operating system is responsible for assigning memory to processes so that processes can be executed. Broadly, this responsibility is defined as memory management, and operating systems handle memory management differently. Any operating system must do two things in order to handle memory effectively. First, an operating system must be able to allocate and free physical memory. Second, an operating system must have techniques in place to...

Types of Operating Systems Within the broad family of operating systems, there are generally four types, categorized based on the types of computers they control and the sort of applications they support. The categories are: * Real-time operating system (RTOS) - Real-time operating systems are used to control machinery, scientific instruments and industrial systems. An RTOS typically has very little user-interface capability, and no end-user utilities, since the system will be a "sealed...

Installing/Upgrading an Operating System Installing/upgrading an operating system or OS, is a rather simple procedure; however, any mistakes can have a profound effect on the computer’s ability to operate. Typically, most users do not have to deal with their computer’s OS as pre-built computers will have the OS already installed and rarely find the need or opportunity to upgrade it. There are a few circumstances that require a fresh install or upgrade for the OS such as installing...

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...

Network Operating Systems vs. MUOS (Multi-User) Characteristics Different methods of Multi-tasking Multi tasking is when the operating system seems to be performing two or more tasks at the same time, i.e. MS Word and MS Access, however these tasks are not actually running simultaneously as they are actually resident in memory processor is actually switching between tasks at a very high speed, therefore each user sees their own task as having priority. One disadvantage can be that the more...

Components of an Operating System In order to perform the actions requested by the computer’s users, an operating system must be able to communicate with those users. The portion of an operating system that handles this communication is often called the user interface. Older user interfaces, called shells, communicated with users through textual messages using a keyboard and monitor screen. More modern systems perform this task by means of a graphical user interface (GUI) in which objects to...

The Purpose and Functions of an Operating System An operating system (OS) is a program that is typically loaded onto the computer’s primary hard drive for the purpose of tying together the hardware with a base platform where a user can input commands and achieve output to a device that is controlled by the OS, such as a screen or printer. Additional programs (applications) are loaded into the operating system to enhance the abilities of the OS for the user or add functions to the OS. Besides...

 Operating System Security Security is the most important part of an operating system when it comes to keeping the system and its information safe. There are various aspects to the security piece in an operating system; which are protocols, kernel and encryption.

Operating Systems Analysis Paper There are many operating systems that are common on the Internet today. Back when computers could only handle one command at a time, in the 1950's, was very time consuming. Now, about sixty years later, a computer's operating system can handle many applications at one time while delivering speed and is user friendly. Although there are many Operating Systems that are available, there are onle a few of them that are well knon and is commonly used. Some of the...

HISTORY OF OPERATIMG SYSTEMS Operating systems (OS) provide a set of functions needed and used by most application programs on a computer, and the linkages needed to control and synchronize computer hardware.

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...
