Nowadays, instead of one big computer doing all the computing, a lot of small computers that are connected do it. These systems are called computer networks. Computer networks are considered as important and practical courses in the field of electrical and computer engineering due to the great use of networks in work environments. The purpose of this course is to learn specialized topics in the field of networking for students in the field of electricity and telecommunications. 

In addition, this course is an introduction to more advanced courses in telecommunications in the field of wireless telecommunications networks.

The advent of computers and computer networks

One of the most important technologies of the twentieth century was the collection, processing and distribution of information. Extensive and international telephone networks, the invention of radio and television, the birth and dramatic expansion of computers, the launch of telecommunications satellites are important symbols of technology of this century.

With the advent of computers and telecommunications, giant computers gave way to computer networks. Now, instead of one big computer doing all the computing, a lot of small computers that are connected do it. These systems are called computer networks.

The importance of computer networking lessons

Computer networking course is one of the most important and practical courses in the field of electrical and computer engineering due to the great use of networks in work environments. 

Another importance of this course is due to its presence in the main courses of the senior IT entrance exam, with a high coefficient. Therefore, learning this course is very important for electrical engineering, computer science and IT senior entrance exam candidates.

This course can also be useful for students of electricity and telecommunications and for those who want to learn more specialized topics in the field of networking. 

In addition, this key course can be an introduction to more advanced courses in senior telecommunications in the field of wireless telecommunications networks, such as cellular cell networks or contingency networks.

One of the important references of computer networking lessons

The Computer Networks book by Andrew S. Tanenbaum is a reference and one of the best books on the web. This book is the reference of this course in many important universities of the world as well as Iran.

General Topics in Computer Networking Lesson 1:

In the first lesson, the basics and general topics related to computer networks are presented. In the second lesson, after a brief introduction to the principles of data communication, the physical layer is discussed. Lesson 3 deals with the data link layer. 

These concepts are time independent and are useful as basic topics at any time. In the fourth lesson, the topics under the layer of control of access to transmission media are discussed.
