DNS
DNS stands for Domain Name System. DNS converts machine names to the IP addresses that all
machines on the net have. It translates from name to address and from address to name.
DOMAIN NAME
The domain name typically refers to an Internet site address.
DTIM
DTIM (Delivery Traffic Indication Message) provides client stations with information on the next
opportunity to monitor for broadcast or multicast messages.
FILTER
Filters are schemes which only allow specified data to be transmitted. For example, the router can filter
specific IP addresses so that users cannot connect to those addresses.
FIREWALL
Firewalls are methods used to keep networks secure from malicious intruders and unauthorized access.
Firewalls use filters to prevent unwanted packets from being transmitted. Firewalls are typically used to
provide secure access to the Internet while keeping an organization's public Web server separate from
the internal LAN.
FIRMWARE
Firmware refers to memory chips that retain their content without electrical power (for example, BIOS
ROM). The router firmware stores settings made in the interface.
FRAGMENTATION
Refers to the breaking up of data packets during transmission.
FTP
FTP (File Transfer Protocol) is used to transfer files over a TCP/IP network, and is typically used for
transferring large files or uploading the HTML pages for a Web site to the Web server.
GATEWAY
Gateways are computers that convert protocols enabling different networks, applications, and operating
systems to exchange information.
HOST NAME
The name given to a computer or client station that acts as a source for information on the network.
HTTP
HTTP (HyperText Transport Protocol) is the communications protocol used to connect to servers on the
World Wide Web. HTTP establishes a connection with a Web server and transmits HTML pages to client
browser (for example Windows IE). HTTP addresses all begin with the prefix 'http://' prefix (for example,
http://www.yahoo.com).
ICMP
ICMP (Internet Control Message Protocol) is a TCP/IP protocol used to send error and control messages
over the LAN (for example, it is used by the router to notify a message sender that the destination node is
not available).
