We know that routers & modems in the field of networking play an essential role. The cost of guided media is very low (inexpensive) and easily available. Security procedures, such as a firewall, cannot stop every problem that might occur when individuals use several different access points simultaneously for their collaboration efforts. The simplicity of joining makes it possible for even young children to begin taking advantage of the information access that computers provide. What is LAN? Distributed Computing is a model in which components of a software system are shared among multiple computers to improve performance and efficiency.. All the computers are tied together in a network either a Local Area Network (LAN) or Wide Area Network . One computer can create problems for the entire network. As for disadvantages, bus topology makes it difficult to determine a network problem if the entire system goes down. Disadvantages of Networks. 9. Downtime. When the data transmission can be done in between two or more computers using a communication medium like cables or wires, then it is called as a computer network. There are several ways that we use them without thinking about their presence in our lives. Organizations use the computer in different fields for different purposes and in different departments.
