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).
Fast Ethernet is a type of LAN that runs up to 10 times
faster than standard Ethernet. It operates at 100Mbps.
10BASE-T and 100BASE-TX are the names given to the
Ethernet protocol that runs over Twisted Pair (TP) cable.
10BASE-T runs at 10Mbps whilst 100BASE-TX operates at
100Mbps. The OfficeConnect Hubs and Switches Use RJ-45
type connectors to connect your TP network.
A network loop occurs when two pieces of network
equipment are connected to each other by two seperate
connections.
A segment is the length of cable connected to a port.
Packets are the units of information your workstations and
other equipment send to each other over the network. A
frame is the data part of the packet and can be unicast
(sent to a single device), multicast (sent to multiple
devices), or broadcast (sent to all devices).
Bandwidth refers to the amount of network traffic the
network can hold at any one time (information capacity)
measured in bits per second (bps). Workstations or
applications that use the network heavily are referred to as
using high bandwidth. Fast Ethernet has a higher
bandwidth than Ethernet, so it can cope with larger
amounts of traffic, which results in faster operation.
Full duplex operation allows information to be transmitted
and received simultaneously and, in effect, doubles the
potential throughput of a link.
