B.Tech Computer Network Notes
Computer Networks are a set of interconnected computers and other devices that communicate with each other to share resources, data, and information. These networks can be used for various purposes, such as sharing files and printers, accessing the internet, communicating via email and messaging, and providing remote access to devices and systems.
Computer networks can be classified into different types based on their size, geographical scope, and the technologies used. Some common types of computer networks include local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs), wireless networks, and the internet.
Below is the syllabus for Computer Networks:-
