Definition
A LAN or other small network, especially one with wireless or temporary
plug-in connections, in which some of the network devices are part of
the network only for the duration of a communications session or, in the
case of mobile or portable devices, while in some close proximity to the
rest of the network.
A specified range of frequencies of electromagnetic radiation.
The Dynamic Host Configuration Protocol (DHCP) is an auto-
configuration protocol used on IP networks. Computers or any network
peripherals that are connected to IP networks must be configured,
before they can communicate with other computers on the network.
DHCP allows a computer to be configured automatically, eliminating the
need for a network administrator. DHCP also provides a central
database to keep track of computers connected to the network. This
database helps in preventing any two computers from being configured
with the same IP address.
A Domain Name System (DNS) server functions as a phonebook for the
Internet and Internet users. It converts human readable computer
hostnames into IP addresses and vice-versa.
A DNS server stores several records for a domain name such as an
address 'A' record, name server (NS), and mail exchanger (MX) records.
The Address 'A' record is the most important record that is stored in a
DNS server, because it provides the required IP address for a network
peripheral or element.
Daylight saving time (DST), also known as summer time, is the practice
of advancing clocks, so that evenings have more daylight and mornings
have less. Typically clocks are adjusted forward one hour near the start
of spring and are adjusted backward in autumn.
Extensible authentication protocol (EAP) refers to the authentication
protocol in wireless networks that expands on methods used by the
point-to-point protocol (PPP), a protocol often used when connecting a
computer to the Internet. EAP can support multiple authentication
mechanisms, such as token cards, smart cards, certificates, one-time
passwords, and public key encryption authentication.
Wireless devices or systems in fixed locations such as homes and
offices. Fixed wireless devices usually derive their electrical power from
the utility mains, unlike mobile wireless or portable wireless which tend
to be battery-powered. Although mobile and portable systems can be
used in fixed locations, efficiency and bandwidth are compromised
compared with fixed systems.
Use of radio frequency spectrum regulated by governments.
Part of the electromagnetic spectrum.
