Ethernet Systems communicating over Ethernet divide a stream of data into shorter pieces called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. The Ethernet provides services up to and including the data link layer. Since its commercial release‚ Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols

TYPES OF NETWORKING A computer network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. Network devices that originate‚ route and terminate the data are called network nodes.[1] Nodes can include hosts such as servers and personal computers‚ as well as networking hardware. Two devices are said to be networked

3ab is a standard for gigabit Ethernet over copper wiring using mostly CAT 5 or CAT6 type network cabling. Each segment of the network has a maximum cable length of about 328 feet or 100 meters. 1000 Base-T standard uses automatic MDI/MDI-X configuration which means straight through cables will often work between gigabit-capable interfaces that can eliminate the needs of a crossover cable (Switch Cabling And Auto-MDIX‚
