LANS

LANS are valuable in an eBusiness solution because they connect workstations and personal computers, enabling the sharing of IP network access.

Each node (individual computer) in a LAN has its own CPU with which it can execute software programs.

LANs enable computers to access data software on other computers on the LAN. This means that many users can share expensive devices, such as laser printers, as well as data.

Users can also use the LAN to communicate with each other, by sending email or engaging in chat sessions, as well as to share connections to the internet.

There are many different types of LANs. Ethernets are the most common for PCs, while most Apple Macintosh networks are based on the AppleTalk network system

You can differentiate among LANS by the following 3 characteristics: 1) topology, the geometric arrangement of devices on the network 2) Protocols, the rules for sending data that determine whether the network uses a peer-to-peer or client/server system 3) Media connection, the means by which a LAN's devices are connected
