10Base-Tx

Specification for 10mbps

In the name 10Base-T, the “10” refers to 10 Mbps

 

 

 

carried over twisted-pair

transmission speed, the “Base” refers to Baseband,

 

 

 

cable.

which means that no frequency multiplexing is

 

 

 

 

applied, and the “-T” refers to Twisted Pair

 

 

 

 

conductors in the cable.

 

 

ARP

Address Resolution

Precedes IP communication between two stations.

 

 

 

Protocol

Deduces Layer 2 MAC address information from

 

 

 

 

IP address information.

 

 

AUI

Attachment Unit Interface

(See MAU, MDI)

 

 

Bit

A unit of binary data.

A binary bit has two values: 1 or 0.

 

 

bps

Bits Per Second

Units of transmission speed

 

 

Bridge

A networking device that

Bridges operate at data link level (or MAC layer)

 

 

 

connects two LANs and

of the OSI model

 

 

 

forwards or filters data

Bridges are transparent to protocols and to higher-

 

 

 

packets between them,

level devices like routers.

 

 

 

based on their destination

 

 

 

 

addresses.

 

 

 

Broadband

A network that uses

Several networks can coexist on a single cable

 

 

Network

multiple carrier frequencies

without interference with each other.

 

 

 

to transmit multiplexed

 

 

 

 

signals on a single cable.

 

 

 

Brouter

A hybrid networking device

A Brouter routes specific protocols such as TCP/IP

 

 

 

that includes functions of a

and bridges others.

 

 

 

router and of a bridge.

 

 

 

Bus

A LAN topology in which

A data transmission from any node is received by

 

 

 

all nodes are connected to a

all other nodes on the Bus.

 

 

 

single cable.

 

 

 

Byte

A data unit of eight bits

 

 

 

Cat-3, Cat-5, Cat-

Category -3, -5 Ethernet

10Base-T can use Cat-3 or Cat-5 cable. Cat-3

 

 

5E

twisted-pair cable, available

includes 4 wires (2 twisted pairs). Cat-5 includes

 

 

 

as Unshielded Twisted Pair

8 wires (4 twisted pairs). 100Base-T can only use

 

 

 

(UTP) or Shielded Twisted

Cat-5 cable.

 

 

 

Pair (STP)

(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.)

 

 

CGI

Common Gateway Interface

A programming standard that connects databases

 

 

 

 

and web browsers.

 

 

Channel

Path through network

insulated from and

earlier networks; Twisted-Pair is popular in current

 

 

 

surrounded by tubular outer

use.

 

 

 

metal conductor.
