and web usage. Without both networking hardware and software total security cannot exist. A Land Are Network (LAN) is a network that connects a group of computers that are within distance of each other to the same network. LAN’s are very useful when it comes to printer sharing and sending and receiving files between all the systems within the facility that share that one network. A LAN is connected by using Ethernet cables‚ adapters‚ and hubs. Its counterpart is the WAN or Wide Area Network a WAN
