NETWORKING

What is NETWORKING?

Computer Networking

imply put, computer networking is the study of how computers can be linked to share data. The concept of connecting computers dates back to the 1960s, when the Department of Defense led the first attempt to create a computer network that painstakingly linked a handful of computers around the U.S. Since then, wireless networking has taken off and networking is now considered an essential part of computing. A computer without a network, arguably, has little use in daily life.

Computer networking involves many things coming together, and there are many challenges and important problems to solve in the field of networking

Studying computer networks

A solid math background is valuable, like all the other computer science and engineering fields. In addition to Calculus, important tools in computer networking and communications include the following:

  • Linear algebra
  • Probability and statistics
  • Differential equations
  • Numerical analysis

Good programming skills are also very important. Although a good programming background may not be necessary for some of the topics under networking (e.g., low-level communications, hardware issues), networking protocols and software require a solid programming background.

Most of the time, students have to develop skills in a new paradigm of programming: distributed programming. In distributed programming, replicas of the same of code run on different machines but work collectively to do a common task. This may sound like parallel programming, but it’s not quite the same. Most of the time, code replicated over the network treats each other as peers and exchanges messages to proceed on a common task, e.g., transferring data from one machine to another.
