Download Computer Networking Textbook – Computer Networking : Principles, Protocols and Practice is an open-source ebook that explains the main principles of Computer Networking and the key protocols that are used on the Internet. The ebook is intended to be used for an upper-level undergraduate networking course.

The first part describes the theoretical foundations of this domain as well and the main algorithms and protocols. The second part contains a detailed explanation of the main Internet protocols including HTTP, DNS, TCP, UDP, IPv6, BGP, RIP, OSPF, Ethernet and WiFi. The last partcontains exercises and practical labs to allow the students to test their knowledge

computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections (data links) between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as WiFi.

Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computersphonesservers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other more general communications protocols. This formidable collection of information technology requires skilled network management to keep it all running reliably.

Computer networks support an enormous number of applications and services such as access to the World Wide Webdigital videodigital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messagingapplications as well as many others. Computer networks differ in the transmission medium used to carry their signals, communications protocols to organize network traffic, the network’s size, topologytraffic control mechanism and organizational intent. The best-known computer network is the Internet.
