Networking Terminology
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.
