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 ...
The word Internet was used in 1945 by the United States War Department in a radio operator's manual, [14] and in 1974 as the shorthand form of Internetwork. [15] Today, the term Internet most commonly refers to the global system of interconnected computer networks, though it may also refer to any group of smaller networks. [16]
TCP/IP's pragmatic approach to computer networking and to independent implementations of simplified protocols made it a practical methodology. [ 48 ] [ page needed ] Some protocols and specifications in the OSI stack remain in use, one example being IS-IS , which was specified for OSI as ISO/IEC 10589:2002 and adapted for Internet use with TCP ...

Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications [1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and ...
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite.
Wi-Fi (/ ˈ w aɪ f aɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.
Computer network engineering is a technology discipline within engineering that deals with the design, implementation, and management of computer networks. These systems contain both physical components, such as routers , switches, cables, and some logical elements, such as protocols and network services .
