DNS - The Domain Name System (DNS) is the way that Internet domain names are located and translated into Internet Protocol (IP) addresses. A domain name is a meaningful and easy-to-remember “handle” for an Internet address. DSSS - Also known as “Direct Sequence Spread Spectrum,” this is a variety of radio transmission methods that continuously change frequencies or signal pat- terns.

LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). MAC Address - The MAC (Media Access Control) address is a unique num- ber assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level.
UDP (User Datagram Protocol) - A communications method (protocol) that offers a limited amount of service when messages are exchanged between com- puters in a network that uses the Internet Protocol (IP).
