In this curriculum area, students learn the fundamentals of computer networking, from ISPs and WIFI to cellular networks, all considered the foundation for the modern information economy. A computer network, or data network, allows computers to exchange data. Its application is fully realized via the best-known format: The Internet. Students learn computer networking issues and design strategy, from sending bits over wires to running distributed applications. Courses help students develop an understanding the inner workings of the Internet and how it supports the Web and other networking applications.
Network computer devices that exchange or terminate data are called network nodes, which include hosts such as personal computers, phones, servers as well as networking hardware. Computer networks differ in the transmission medium used to carry their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent.
Students will learn how to support an enormous number of applications, such as access to the World Wide Web, video, digital audio, shared use of application and storage servers, printers, and fax machines, use of email and instant messaging applications, as well as many others.
Computer networking enables such companies as Google, Facebook and Amazon.
