A Communication is the process of transferring messages from one point to another. It is a very vital process in a network. When two networks are connected with each others they have to share data to each others so this process of communication system has three basic elements which are as follows - 1. A sender (source), which creates the message to be transmitted. 2. A medium, which carries the message, 3. A receiver (sink), which receives the message. Data communication is the function of transmitting data from one point to another. In this case, the sender and receiver are normally machines, in particular, computer devices (computers, terminals, peripheral devices like printers, plotters, disks, etc), and the transmission medium may be telephone lines, microwave links, satellite links, etc. However, the messages that are transmitted are only in data form, but not in voice conversations form. Hence, the electronic systems, which transfer data from one point to another, are called dat

Operating System (OS): An Operating system consists of a set of programs which controls, co-ordinates and supervises the activities of the various components of a computer system. Its function is to link between the computer hardware and the user. An operating system is a software or a series of programmes, which performs various types of functions in order to manage and organize file so". Objectives:  There are lot of objectives of an operating system, actually it covers the birth of a perfect operating system. A user is just like a wanting animal they just want everything. But as a developer we are just tying to make our software more & more better as per user requests. These are some main objectives ------ To describe the basic organization of computer systems. To provide a grand tour of the major components of operating systems. Provide more convenient environment for users. Provide maximum utilized performance to users as per hardware existance.
