Local Area Networks (LAN) is widely used to share resources and exchange information by connecting personal computers and workstations in the company offices and factories. A LAN is a network that is limited to an area such as a building or school. In a LAN, computers, and hardware such as printers can be connected by cable (copper wiring), fiber optic cabling (glass fibers), or using a wireless (radio waves) connection.Embedded System It is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system.At the core is an integrated circuit designed to carry out computation for real-time operations.Router It is the piece of network hardware that allows communication between your local home network”like your personal computers and other connected devices”and the internet.The router used in home and small networks is more accurately called a residential gateway.It is a combination of hardware and software which links two parts of the same LAN by directing messages to the correct node.A hybrid computerIt is a computing system that combines both digital and analog components. Traditionally, the analog components of the computer handle complex mathematical computations.The digital components take care of logical and numerical operations, in addition to serving as the controller for the system.A microprocessorIt is an integrated circuit (IC) that incorporates core functions of a computers central processing unit (CPU). It is a programmable multipurpose silicon chip, clock-driven, register-based, accepts binary data as input, and provides output after processing it as per the instructions stored in the memory.Hence, it is clear from the above points that a combination of hardware and software which links two parts of the same LAN or two compatible LANs by directing messages to the correct node is called Router.
