Question 1: Computer network: A computer network is a group of computer systems and other computing hardware apparatus that are connected together through communication channels to facilitate connection and resource-sharing among a broad range of users. Systems are routinely categorized founded on their characteristics. One example for a computer network was a network of communicating computers that functioned as part of the U.S. military's Semi-Automatic Ground natural environment (SAGE) radar

TCP/ IP is the basic communication language for the internet. It can be used in private networks such as the intranet and extranet. Any computer that you send a message to gets a copy of the TCP/IP. TCP/IP is a two layer protocol consisting of transmission control protocol(TCP) and the lower layer Which is Internet protocol which handles addressing so that each packet gets to its destination. TCP will be in control of managing the assembling of a message that Is being sent. IP is responsible for

Voice and Data Communication Elisha Myles NTC/360 February 21, 2011 In many households can have various setups of a network from basic Internet connections to electronic devices. Here we will explain how one home network system can be achieved with the proper hardware and devices to make it work. In this home network consist of one desktop computer hard wired with Arris Telephone Telephony cable modem and CATV coaxial cable wiring provided by the cable company. The computer is connected

The reason behind TCP/IP’s dominance over OSI can be summarized as a result of technical, political and economic reasons: The reasons for the popularity of TCP/ IP over the OSI are : * TCP/IP answers an immediate, almost desperate need - data communications in heterogeneous networks - very well. * It is relatively simple and robust compared to other alternatives. * TCP/IP is bundled into the Berkeley Software Distribution (BSD) Unix. Hence, TCP/IP became the minimum networking capability
