Receiving address: The MAC address of the access point that should receive the frame
Symmetric Digital Subscriber Line (SDSL): A device that establishes data connections across phone lines and has upload and download speeds that are the same
Sequence control field: A field that is 16 bits long and mainly contains a sequence number used to keep track of ordering the frames
Short-range wireless network: It is what mobile devices uses to connect to their peripherals
T-Carrier technologies:Technologies Invented to transmit multiple phone calls over a single link. Eventually, they also became common transmission systems to transfer data much faster than any dial-up connection could handle
Transmitter address: The MAC address of whatever has just transmitted the frame
Wi-Fi Protected Access (WPA): A security program that uses a 128-bit key to protect wireless computer networks, which makes it more difficult to crack than WEP
Wide area network:Acts like a single network but spans across multiple physical locations. WAN technologies usually require that you contract a link across the Internet with your ISP
Wired Equivalence Privacy (WEP): An encryption technology that provides a very low level of privacy. WEP should really only be seen as being as safe as sending unencrypted data over a wired connection
Wireless access point: A device that bridges the wireless and wired portions of a network
Wireless LANS (WLANS): One or more access points act as a bridge between a wireless and a wired network
Wireless networking: Networks you connect to through radios and antennas
A
A record: The most common resource record, used to point a certain domain name at a certain IPv4 IP address
ACK flag: One of the TCP control flags. ACK is short for acknowledge. A value of one in this field means that the acknowledgment number field should be examined
