It addresses all four major architectural layers of modern computer networks (application layer, transport layer, network layer and link layer), as well as selected topics from multimedia networking, wireless networking and network security. 1 – Introduction to Computer Networks & Internet 7 Prof. Maulik Trivedi, CE Department | 2140709 – Computer Networks (CN) The concept of clients and servers is essential in the network design. Server takes and processes request on behalf of Clients. These are preferred as they are easy to design and troubleshoot. By Chaitanya Singh | Filed Under: Computer Network. Introduction to computer network 1. Personal computers and workstations are generally preferred to have a LAN network. Not only that. Sometimes, there are problems when computers on the internet or on these business networks try to communicate with each other and often, it's up to an IT support specialist to fix these problems. Client-server networks feature centralized server computers that store email, web pages, files, and applications accessed by client computers and other client devices. Introduction to computer networks and TCP/IP Protocols, The TCP/IP protocol suit and the TCP/IP model The concept of layering, The job of each layer, Connectionless vs. Examples of other shared resources can include a printer or a file server. What is a Computer Network? Computer Network is a group of computers connected with each other through wires, optical fibres or optical links so that various devices can interact with each other through a network. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. A computer network can be defined as a set of computers connected together for the purpose of sharing resources. Computer networks can be discriminated into various types such as Client-Server, peer-to-peer or hybrid, depending upon its architecture. Chap. The Internet drives tremendous change in the world while continuously changing and evolving itself. As I wrote earlier, you will learn the most important concepts of Computer Networks. Anyone who is studying on their Computer Network exam. Comments & Suggestions Search for: Reading: Computer Network. Missed the LibreFest?
