Domain
A subnetwork comprised of a group of clients and servers under the control of one
security database.

DoS (Denial of Service) Attack
An attempt to make a machine or network resources unavailable to its intended users.
DNS (Domain Name System)
An Internet service that locates and translates domain names into IP addresses. Because
domain names are alphabetic, they are easier to remember. However, the Internet is
based on IP addresses. Every time you use a domain name, a DNS service translates the
name into the corresponding IP address. The DNS system is actually its own network. If
one DNS server does not know how to translate a particular domain name, it asks another
one, and so on, until the correct IP address is returned.
Downstream

DTIM (Delivery Traffic Indication Message)
Informs clients about the presence of buffered broadcast data on the access point.

common transmission medium. It forms the underlying transport vehicle used by several
upper-level protocols, including TCP/IP, HTTP, and FTP.
Firewall
A highly effective method to block unsolicited traffic from outside the connected
computers in your gateway and local network.
FTP (File Transfer Protocol)
