Local Area Network
A Local Area Network (LAN) is a regional, local PC network. The PCs are all equipped with a network interface
card and work with one another via data exchange. The LAN requires an operating system on each PC and
standardized data transport software. The operating systems can be different, as can the data transport soft-
ware, but both must support a common transmission protocol (= TCP/IP protocols), so that all PCs can
exchange data with one another.
