For example, if four computers run the same program and any computer has a hardware error, then other computers can override it. Security through redundancy: Multiple computers running the same program at the same time can provide the security through redundancy.

Faster problem solving: Multiple computers can solve the problem faster than a single machine working alone.For example, a bank allows the users to access their own accounts through an ATM without allowing them to access the bank's entire database. Security: It provides limited interaction that a user can have with the entire system.As both the number and types of students. Annotation As one of the fastest growing technologies in our culture today, data communications and networking presents a unique challenge for instructors. Following are the advantages of Distributed processing: Huga Media, 2007 - Asynchronous transfer mode - 1134 pages. Instead, a single computer handles an entire task, each separate computer handles a subset. The links connecting the nodes are known as communication channels.Ĭomputer Network uses distributed processing in which task is divided among several computers. It was standardized in IEEE 802.3 in 1980. As one of the fastest growing technologies in our culture today, data communications and networking presents a unique challenge. This technology was invented by Bob Metcalfe and D.R. A node can be computer, printer, or any other device capable of sending or receiving the data. Data Communication and Computer Network 8 Let us go through various LAN technologies in brief: Ethernet Ethernet is a widely deployed LAN technology. What is Computer Network?Ī computer network is a set of devices connected through links. One goal is to give some insight into the rationale of why networks are. Our Computer Network tutorial includes all topics of Computer Network such as introduction, features, types of computer network, architecture, hardware, software, internet, intranet, website, LAN, WAN, etc. 6.263J / 16.37J focuses on the fundamentals of data communication networks. Our Computer Networking Tutorial is designed for beginners and professionals. defines what is communicated, how it is communicated, and when it is. A protocol is a set of rules that govern data communications. An entity is anything capable of sending or receiving information. Computer Network tutorial provides basic and advanced concepts of Data Communication & Networks (DCN). I.Protocols: In computer networks, communication occurs between entities in different.
