Auto Sensing Network Switch: A piece
of network hardware that acts as a central connection point in a residential
or business LAN. It is preferable to use a switch versus a hub, because
it increases capacity and decreases network loading by dividing a LAN into
different segments, which don't compete with each other for network transmission
capacity. A switch acts as a selective bridge that automatically forwards
traffic from one segment to another, without interference. In other words,
a switch works better than a HUB.
10BaseT: 10 megabits per second of
data transmitted over an unshielded, twisted pair of cable.
100BaseT: 100 megabits per second
of data transmitted over an unshielded, twisted pair of cable.
Category 5 Cable (Cat 5): A cable
that uses, solid core telephone wires, versus stranded, and includes 4 pairs
(8 wires) of unshielded twisted wire. This is currently the most popular
cable used in a 10/100 Ethernet based network. RJ45 connectors and Jack
Modules are used on this cable.
Category 5e Cable (Cat 5e): Similar
to Cat 5 cable, but is enhanced to support speeds of up to 1000 megabits
per second.
Client: Any computer on a LAN, other
than the Host Computer or a Server. A Client is the remote computer that
shares the satellite connection with the Host computer.
Crossover Cable: This is also called
a "Crossed Cable." A Cat 5 or 5e cable that is used to connect
one Personal Computer (PC) to another PC or one switch to another switch.
Ethernet: A method used to access
a Local Area Network (LAN). Token Ring is another method, but not widely
used. Ethernet can be used on a shared network, where all clients share
the bandwidth or on a switched network where each sender and receiver pair
have the full bandwidth. Ethernet uses a technology that broadcasts each
frame onto a medium such as wire or fiber. All computers, on the network,
are listening. The computer with the matching destination address, accepts
the frame and checks for errors. Ethernet was invented in 1973 by Robert
Metcalfe and David Boggs of Xerox. It ran at 2.93 megabits per second (Mbps).
Ethernet Cable: Any cable used to
connect computers, hubs, switches, routers, etc. The most popular, for home
use, is Cat 5 or Cat 5e.
10/100 Ethernet Card: A card that
is installed in a computer to facilitate the connection to an Ethernet based
LAN. It will support up to 100 megabits per second of data transmitted over
a UTP cable. This is also called a Network Interface Card (NIC).
10/100 Ethernet Network: An Ethernet
based network that supports both 10BaseT and 100BaseT speeds.
Fast Ethernet: An Ethernet Network
that will support up to 100 megabits per second of data transfer.
Host Computer: The computer that is
connected directly to your satellite ITU and IRU modems (also called adapters).
Local Area Network (LAN): Two or more
computers, tied together in a network, usually confined to one building
or a group of associated buildings.
Network Interface Card (NIC): A card
that is installed in a computer that enables a computer to be connected
to a LAN and communicate with other computers on that LAN. The 10/100 are
currently the most popular.
110 Punch-Down Impact Tool: The proper
tool used to install wires on the back of the RJ45 Jack Module. They are
available from many sources on the Internet with prices as low as $15.00.
110 is the type of blade used for the RJ45 Jack Module which is a 110 type
connecting block. (see figure 1)
