A Network is a collection of workstations (for example,

IBM-compatible PCs) and other equipment (for example,

printers), connected for the purpose of exchanging

information or sharing resources. Networks vary in size,

some are within a single room, others span continents.

A Local Area Network (LAN) is a network, usually in an office,

that spans no more than a single site.

Ethernet is a type of LAN, referring to the technology used to

pass information around the network. It operates at

10Mbps (megabits per second).

10BASE-T is the name given to the Ethernet protocol that runs

over Twisted Pair (TP) cable.

10BASE-2 is the name given to the Ethernet protocol that runs

over Coaxial cable.

A Network Loop occurs when two pieces of network equipment

are connected by more than one path. Your hub detects

this and Partitions (isolates) one of its ports to break the

loop.

A Segment is the length of c able connected to a port, whether

this cable is 10BASE-T, 10BASE-2 (Coax), or another type .

When you daisy-chain equipment together with

10BASE-2 (Coax) cable, all of the cable forms a single

segment.

Packets are the units of information your workstations and other

equipment send to each other over the network.

Collisions are a part of normal Ethernet operation and occur if

two or more devices (pieces of network equipment)

attempt to transmit at the same time. A sudden

sustained increase in the number of collisions can

indicate a problem with a device, particularly if it is not

accompanied by a general increase in traffic. On coaxial

segments an increase in collisions can also indicate faulty

cabling.
