LAN Computer Platform - Essay Example

Computer Platform Abstract The paper discusses the computer platform “LAN” in detail. It explains how a LAN computer network can be organized and execute. The paper analyzes the various aspects of the LAN and it compares various operating systems that can be implemented on the LAN. It suggests best hardware for the proposed network.
