Information about operating system
An operating system ( OS ) is system software that manages computer hardware , software resources, and provides common services for computer programs . Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time , mass storage , printing, and other resources. For hardware functions such as input and output and memory allocation , the operating system acts as an intermediary between programs and the computer hardware, [1] [2] although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it.

Basic information of Ethernet
Ethernet is a way of connecting computers together in a local area network or LAN. It has been the most widely used method of linking computers together in LANs since the 1990s . The basic idea of its design is that multiple computers have access to it and can send data at any time. This is comparatively easy to engineer. If two computers send data at the same time, a collision will occur. When this happens, the data sent is not usable. In general, both computers will stop sending, and wait a random amount of time, before they try again. A special protocol was developed to deal with such problems. It is called Carrier sense multiple access with collision detection or CSMA/CD. L.A.N. Local Area Network
Information of about computer
A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming . Modern computers have the ability to follow generalized sets of operations, called programs . These programs enable computers to perform an extremely wide range of tasks. A "complete" computer including the hardware , the operating system (main software ), and peripheral equipment required and used for "full" operation can be referred to as a computer system . This term may as well be used for a group of computers that are connected and work together, in particular a computer network or computer cluster . Computer Computers and computing devices from different eras Computers are used as control systems for a wide variety of industrial and consumer devices . This includes simple special pur...
