Document Summary
Then there was a direct connection using a cord: the first computer would only recognize the other computer as another external hard drive. Connecting computers direct connection: 8 bits/byte is a standard but in early computer days, different computers had a different bit count/byte. Time-sharing: multiple users having access to one computer, long-distance use is applicable. Hubs: sends data to all computers on the lan, everyone one get the data but no one would know who from, not complex or expensive. Switches: send data only to the computers on the lan it is intended for, identifies source and destination, specifically to a specific place and no where else, complex and expensive. Routers: directs data to all computers on the lan, can send data from one computer to another and one lan to another. Network interface card (nic: gives a computer a unique address making it apart of the network. Media access controller address: address assigned to the nic card.
