Glossary D-8
RJ-45 A connector/socket for four pairs (either wires) of twisted pair cable that is 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 the 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 It sets the RTS threshold. Any packet size above this value, requires RTS. For
packets smaller than this threshold value, RTS is not sent and the packet is
transmitted directly to the wireless LAN.
Service Set Identifier
(SSID) 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 the
other part is 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, that is 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.
