also Reverse ARP (RARP) which can be used by a host to discover its IP address. In this case, the host

will accommodate either type of cable to make the right

connection.

CA

A Certificate Authority is a trusted third-party organization or company that issues digital certificates used
to create digital signatures and public-private key pairs.

Cat 5

Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second
(10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be
rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA).
This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four
twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum
cable length for both 10 and 100 Mbits/second networks.

Certificate Authority

A Certificate Authority is a trusted third-party organization or company that issues digital certificates used
to create digital signatures and public-private key pairs.
The role of the CA in this process is to guarantee that the individual granted the unique certificate is, in fact,
who he or she claims to be. Usually, this means that the CA has an arrangement with a financial institution,
such as a credit card company, which provides it with information to confirm an individual's claimed
identity. CAs are a critical component in data security and electronic commerce because they guarantee that
the two parties exchanging information are really who they claim to be.

DHCP

An Ethernet protocol specifying how a centralized DHCP server can assign network configuration
information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and
gateway (router) addresses.

DMZ

Specifying a Default DMZ Server allows you to set up a computer or server that is available to anyone on
the Internet for services that you haven't defined. There are security issues with doing this, so only do this if
you'll willing to risk open access.

DNS

Short for Domain Name System (or Service), an Internet service that translates domain names into IP
addresses.
