Service Set Identifier (SSID) is more generic and is a 32-character name that uniquely identifies all the computers and equipments
that make up a wireless network. A type of SSID is ESSID. Another type of SSID is Basic Service Set Identifier (BSSID). The
BSSID is the MAC address of a wireless adapter or Access Point.
Port
A port is a connector on a networking device used to attach the network cable. Hubs and switches have numerous ports that
connect to computers on the network.
Protocol
Protocol refers to a set of rules for sending and receiving information on a network. The rules determine the format of the data that
is transmitted and other aspects of networking, such as how errors are detected and corrected. The protocol driver in each
computer is software that adheres to these rules when sending and receiving information. These drivers are also often called
protocols.
Transmission Control Protocol/Internet Protocol (TCP/IP)
TCP/IP refers to the protocol that computers use to communicate over the Internet. TCP determines how a computer breaks up
data into small units, called "packets," to be sent to another computer and how the receiving computer reassembles the packets
into a single file. IP determines how the packets are routed across the Internet. See Internet Protocol.
Virtual Local Area Network (VLAN)
A VLAN is a network of computers that behave as if they are connected to the same wire, even though they may be physically
located on different segments of a LAN. VLANs are configured through software rather than hardware, which makes them
extremely flexible. When a computer on a VLAN is physically moved to another location, it can stay on the same VLAN without any
hardware reconfigurations.
Virtual Server
A virtual server is a device that performs Internet protocol (IP) mapping. IP mapping allows remote client access to your network
via the Internet.
Wide Area Network (WAN)
A WAN is a communications network that uses devices such as telephone lines, satellite dishes, or radio waves to span a larger
geographic area than can be covered by a LAN.
Wireless Local Area Network (WLAN)
A WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to communicate and
transmit data among the network clients and devices. It is a flexible data communication system implemented as an extension to,
or as an alternative for, a wired LAN. Just like a LAN, the network lets users at that location share files, printers and other services.
