How computer communicate???????

How Computers Communicate . Data communication is the most important branch of the information technology. Today no business can be successful with the proper implementations of the communication systems. Computers can talk to each other to send and receive the voice, video and data signals. For two computers to communicate each other it is important that both the computers should understand a common language known as protocols.

OSI There are seven layers in the OSI layers model. Application Presentation Session Transport Network Data Link Physical

A Hub or switch is required. A DSL router is required. A wireless router.
