Comments
In the name 10Base-T, the "10" refers to 10 Mbps
transmission speed, the "Base" refers to Baseband,
which means that no frequency multiplexing is
applied, and the "-T" refers to Twisted Pair
conductors in the cable.
Precedes IP communication between two stations.
Deduces Layer 2 MAC address information from
IP address information.
(See MAU, MDI)
A binary bit has two values: 1 or 0.
Units of transmission speed
Bridges operate at data link level (or MAC layer)
of the OSI model
Bridges are transparent to protocols and to higher-
level devices like routers.
Several networks can coexist on a single cable
without interference with each other.
A Brouter routes specific protocols such as TCP/IP
and bridges others.
A data transmission from any node is received by
all other nodes on the Bus.
10Base-T can use Cat-3 or Cat-5 cable. Cat-3
includes 4 wires (2 twisted pairs). Cat-5 includes
8 wires (4 twisted pairs). 100Base-T can only use
Cat-5 cable.
(Note: Cat-5 cabling and connectors are more
reliable than those for Cat-3. Cat-5E refers to the
Enhanced version of Cat-5.)
Both Cat-3 and Cat-5 cables are limited to 100
meters (328 feet) per segment, and both use RJ-45
connectors.)
A programming standard that connects databases
and web browsers.
Examples are Thin Ethernet (RG-58/AU or
RG48/CU) and Thick Ethernet (RG-8) with BNC
connectors. Coaxial cable was commonly used for
earlier networks; Twisted-Pair is popular in current
use.
