Computer Network

A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices pass data to each other along network links (data connections). Data is transferred in the form of packets. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones, servers as well as

Computer Maintenance and troubleshooting

For the smooth functioning of computer system it is frequently required to upkeep, maintain,  repair, troubleshoot and take up preventive maintenance of the system and its peripheral devices. Therefore it is essential for the students to acquire skills in the area of computer maintenance and troubleshooting and its preventive maintenance. 

Identify basic components of a personal computer

A peripheral is any computer device that is not part of the essential computer but is relatively close by. Peripherals are often called input/ output (I/O) devices. Some peripherals are in the same case as the main part of the computer, such as the hard drive or CD-ROM drive. Other peripherals, such as the printer, monitor, or scanner, are outside the computer case and are attached by a wired or wireless connection.

Computer Network : Updates in Lab Manual, Presentation, Ebook

Computers and computer networks are the sole of the present telecommunication system. Advanced digital communication system is based on the computer networks. Now a days every organisation, industry or the service sector own their private computer networks. Therefore in every organisation, the maintenance of the computer networks becomes one of the essential jobs of a diploma electronics engineer too. This course is therefore designed to help the Electronics and Communication diploma holders to develop this competency.

Computer Networking : Principles, Protocols and Practice by Olivier Bonaventure in Ebook

This textbook came from a frustration of its main author. Many authors chose to write a textbook because thereare no textbooks in their field or because they are not satisfied with the existing textbooks. This frustrationhas produced several excellent textbooks in the networking community. At a time when networking textbooks were mainly theoretical, Douglas Comer chose to write a textbook entirely focused on the TCP/IP protocol suite [Comer1988], a difficult choice at that time. He later extended his textbook by

Introducing Basic Network Concepts : Notes

Networks are everywhere or so it seems. You can hardly do anything with data that does not involve a network. Like the human networks that we are all part of, computer networks let us share information and resources. In business, the reliance on networks is even more pervasive than in homes or schools. Networks help individuals and businesses alike save money, but they also help create income. Without a doubt,

Mobile Communication Notes

In Notes:

There are a variety of wireless communication systems for transmitting voice, video, and data in local or wide areas. There are point-to-point wireless bridges, wireless local area networks, multidirectional wireless cellular systems, and satellite communication systems.This topic discusses "mobile" wireless technologies that provide voice and data communication services to mobile users who use cell phones, PDAs, Internet terminals, and related computing devices. Refer to "Wireless Communications" for a list of related wireless
