Glossary E-8
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.
RTS (Request to
Send) Threshold This threshold refers to when your device 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.
SSID (Service Set
Identity) A group name shared by all members of an IEEE 802.11 standard wireless
network. Only wireless devices with the same SSID are allowed to establish
connections.
Static IP address A permanent IP address assigned to a computer (host) connected on a specific
network.
Subnet or
Subnetwork Any network that is a part of a larger IP network and is identified by a subnet
address.
Subnet Mask A 32-bit string of a TCP/IP address — a part of which is the network address and
another part the host address. A Subnet Mask is usually represented in dotted-
decimal notation, for example, 255.255.255.0.
Switch A device used for connecting nodes in a star topology. In a star topology, all nodes
are connected to a central switch. By monitoring packets, a switch learns which
devices are connected to its ports and then sends a packet to the appropriate port
only.
