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. On the first computers‚ with no operating system‚ every program needed the full hardware specification to run correctly and perform standard tasks‚ and its own drivers for peripheral devices like printers and punched paper card readers. The growing complexity of hardware and application programs

changing an operating system......... 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

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

EVOLUTION OF THE OPERATING SYSTEM Operating systems as they are known today trace their lineage to the first distinctions between hardware and software. The first digital computers of the 1940s had no concept of abstraction; their operators inputted machine code directly to the machines they were working on. As computers evolved in the 1950s and 1960s however‚ the distinction between hardware such as the CPU and memory (or Core as it was called then) and the software that was written on top of it
