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 .
The history of the Internet originated in the efforts of scientists and engineers to build and interconnect computer networks.The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.

Computer networking may be considered a branch of computer science, computer engineering, and telecommunications, since it relies on the theoretical and practical application of the related disciplines. Computer networking was influenced by a wide array of technological developments and historical milestones.
The history of computing is longer than the history of computing hardware and modern computing technology and includes the history of methods intended for pen and paper or for chalk and slate, with or without the aid of tables.
For a long period of time, the network engineering community was polarized over the implementation of competing protocol suites, a debate commonly called the Protocol Wars. It was unclear which type of protocol would result in the best and most robust computer networks. [47]
Donald Davies independently invents packet switching used in modern computer networking. [21] [17] Davies conceived of and named the concept for data communication in 1965 and 1966. [22] [23] Many packet-switched networks built in the 1970s, including the ARPANET, were similar "in nearly all respects" to his original 1965 design. [24] 1965: US
Computer networks engineering is the field dedicated to the design, development and management of interconnected computer systems that facilitate data communication and resource sharing. It encompasses protocols, hardware, and software to ensure reliable and secure connectivity.
