IPv6 The most recent version of the Internet Protocol (IP) in common use today. IPv6 is gradually replacing IPv4, which is the most widely used version of IP today. The Internet Assigned Numbers Authority, which is responsible for the worldwide allocation of IP addresses, announced that it had assigned the last block of IPv4 addresses to a Regional Internet Registry on January 31, 2011. This has led to an increased push for adoption of IPv6. IPv6 addresses consist of 128 bits, so the theoretical maximum number of IPv6 addresses is 2128, or about 3.4x1038 addresses.
ISP Internet Service Provider. A company that provides access to the Internet.
Man Pages Help files for UNIX and Linux commands, which can be found by typing "man" (short for "manual") followed by the name of a UNIX or Linux command.

RAID Redundant Array of Independent Devices. A system for ensuring data integrity by storing data on multiple disk drives.
RAM Random Access Memory. This is reusable computer memory, available to all programs on a computer. A computer with 32M of RAM has about 32 million bytes of memory that programs can use. RAM is read/write memory, as opposed to ROM which is read-only memory.
Redirect The process of automatically sending a site visitor to another Internet location. The location can be a subdirectory on another site or even a particular web page.

For example, the "example" in Second level domain names are often descriptive and have come to be used increasingly to represent businesses and other commercial interests on the Internet.
Sendmail The BSD Unix Message Transfer Agent supporting mail transport via TCP/IP using SMTP. Sendmail is normally invoked in the background via a Mail User Agent such as the mail command.
Server A computer or device that manages network resources. The term can refer to a piece of software, or to the machine on which the software is running. A single server machine could be running several different server software packages, thus providing many different services to users on the network.
Shell A UNIX command processing envoronment.
Shopping cart Software used to create an online "storefront," or E-Commerce Web site.

Each specific application will have its own version of SQL implementing features unique to that application, but all SQL-capable databases support a common subset of SQL.
SSL Secure Sockets Layer: A protocol for encrypted communications across the Internet. It provides privacy, authentication, and message integrity. SSL is often used in communications between browsers and servers. A URL that begins with "https" is a clue that an SSL connection will be used on the Web site. During an SSL connection, each side sends a Security Certificate to the other. Both sides then encrypt what they send, ensuring that only the intended recipient can decode it.
Subhost A domain or web site that shares a server with another domain or website.

Traceroute A TCP/IP utility that allows a user to determine if two computers are communicating successfully with each other.
TTL Time To Live. This value determines the length of time, in seconds, that a non-authoritative name server will keep a cached (stored) copy of a zone file. In other words, this is how long a DNS change will take to spread across the Internet. While lower values allow changes to take effect more quickly, they also increase the probability that a server will be unavailable in the event of a name server failure, as well as increase vulnerability to a type of attack known as DNS cache poisoning.
