An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...

Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
All courses are free to enrol and learn from. The certification exam is optional and comes at a fee of Rs 1000 per course exam. Course credits can also be transferred to other higher education institutions student or the Academic Bank of Credits under the UGC guidelines. NPTEL courses aim for equitable access.
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).
Wi-Fi provides wireless access to the Internet via local computer networks. Hotspots providing such access include Wi-Fi cafés, where users need to bring their own wireless devices, such as a laptop or PDA. These services may be free to all, free to customers only, or fee-based. Grassroots efforts have led to wireless community networks.
Flooding is used in computer network routing algorithms in which every incoming packet is sent through every outgoing link except the one it arrived on. [ 1 ] Flooding is used in bridging and in systems such as Usenet and peer-to-peer file sharing and as part of some routing protocols , including OSPF , DVMRP , and those used in ad-hoc wireless ...
The physical layer is responsible for physical transmission of the data, link encapsulation allows local area networking, IP provides global addressing of individual computers, and TCP selects the process or application (i.e., the TCP or UDP port) that specifies the service such as a Web or TFTP server.
