Networks and Communications in Computer

 Computer Networks:

                                  Most computer systems are now connected together in some way to form what is known as a Network. This Ranges from basic school or home network of only a few computers to large networks such as the internet. This ranges from a basic school or home network of only a few computers to large networks such as the Internet.

What is Networks?

                     "A computer network is interconnection of two or more computer system                              located in a some room, building or at different places."                                         

Computer network enables the sharing of information, programs and hardware components. A computer network in an office, company or in a computer lab connects many computers and other devices such as printers with each other using cables.

Components of Computer Network:

     A Computer Network consist of the following four basic components;

• Sending Device
• Receiving Device
• Communication Device
• Transmission Medium

Sending Device:

                      A Device which is used to send messages, data or information to other device connected to a network is called a Sending Device. In a computer network a sending Device is usually computer.

Receiving Device:

                             In a Computer Network a receiving Device receives messages, data or information from a sending device. The receiving Device could be a computer, printer or a Storage device.

Communication Device:

                                    Communication devices are used for communication between computers and other devices. A modem is a popular communication device which is used for internet connection.

Transmission Media:

                              Transmission Media is the channel or path through which the data or information is transferred from one place to another in a computer network. Networks are connected by the wired or wireless transmission medium.
