GLOSSARY 3
IEEE | Institute of Electrical and Electronics Engineers. Committees that |
| develop and propose computer standards, such as the 802 protocols, |
| which define the physical and data link protocols of communication |
| networks. Members represent an international cross section of users, |
| vendors, and engineering professionals. |
incoming | The ability of a device to receive pause frames. See symmetric |
flow control | flow control. |
LAN | Local area network. An assembly of computing resources such as PCs, |
| printers, minicomputers, and mainframe computers linked by a |
| common transmission medium, such as UTP. |
LED | |
| commonly used in digital displays. |
MAC | Media Access Control. The data link sublayer that is responsible for |
| transferring data to and from the physical layer. |
Mbps | Megabits per second. |
outgoing | The ability of a device to send pause frames. See Asymmetric |
flow control | flow control. |
partition | A repeater function that isolates a particular port from the network |
| because of an excessive number of collisions. Once the problem |
| causing the collisions is corrected, the port is reactivated. |
pause frame | A set of bits that tells a transmitting device to stop the transmission of |
| data frames for a specified period or to resume the transmission of |
| data frames. |
power workgroup | A small number of servers or a small number of sophisticated users |
| on |
| performance to run applications that move and process massive |
| amounts of data in real time (for example, medical imaging, video |
| editing, film postproduction, CAD/CAM, or digital prepress). |
repeater | A device that extends the length, topology, or interconnectivity of |
| the physical medium beyond that imposed by a single segment, up |
| to the maximum allowable |
| Repeaters perform the basic actions of restoring signal amplitude, |
| waveform, and timing applied to normal data and collision signals. |
