Packet Internet Groper (PING)
An Internet program used to determine whether a specific IP address is
accessible. It works by sending a packet to the specified address and waiting for
a reply. PING is used primarily to troubleshoot network connections.
Preamble
A preamble is a signal, in the form of series of pulses, used in network
communication to synchronize the transmission timing between two or more
systems. There are two options, Short and Long. The Short option improves
throughput performance.
Protocol
A set of agreed-upon rules for transmitting data between two devices. A user's
laptop must support the right protocols for the laptop to communicate with other
computers.
Reboot
When a computer is shut down and restarted, it is rebooting.
RJ-11
A connector/socket for two pairs (four wires) of twisted pair cables that are used
primarily to connect telephone equipment in the United States.
RJ-45
A connector/socket for four pairs of twisted pair cables that are used commonly to
connect computers onto a local-area network, especially to the Ethernet. The
only difference between an RJ-45 and RJ-11 connector is that an RJ-45
connector is slightly wider.
Router
A hardware device that connects two separately functional networks using the
same or different protocols. Routers look at the destination addresses on the
packets passing through them and then decide which route to send them on.
Request to Send (RTS) Threshold
This threshold refers to when your PCMCIA card sends out RTS frames to
reserve bandwidth for maximum data transmission. If a transmitted data frame is
larger than the threshold value, the RTS frame sent out will request for more
bandwidth.
