Controlling Broadcast Frames with Virtual LANs (934 words) |
 | A virtual LAN consists of two or more Token Ring segments that are joined by Catalyst 1600 devices, where stations can only make connections to other stations or servers that are part of the same virtual LAN. |
| Although the virtual LANs share the ring on which the servers are located, broadcast frames are not forwarded from either virtual LAN onto rings that only belong to the other. |
| In a permeable virtual LAN, any ring that is connected directly to a ring that belongs to the virtual LAN can forward broadcast frames onto the virtual LAN, and receive broadcast frames from inside the virtual LAN. |
| What is local-area network? - A Word Definition From the Webopedia Computer Dictionary (595 words) |
| Each node (individual computer) in a LAN has its own CPU with which it executes programs, but it also is able to access data and devices anywhere on the LAN. |
| Users can also use the LAN to communicate with each other, by sending e-mail or engaging in chat sessions. |
| LANs are capable of transmitting data at very fast rates, much faster than data can be transmitted over a telephone line; but the distances are limited, and there is also a limit on the number of computers that can be attached to a single LAN. |
