Word Description
A record A DNS record that points a domain name or hostname (such as mail.example.com) to an IP address (such as 192.0.43.10). An example A record might look like this: www.example.com. 86373 IN A 192.0.43.10 This would indicate that the hostname www.example.com points to the IP address 192.0.43.10.
AAAA record The IPv6 equivalent of an A record. An AAAA record points a domain name or hostname (such as mail.example.com) to an IPv6 address (such as 2001:500:88:200::10). An example AAAA record might look like this: example.com. 86400 IN AAAA 2001:500:88:200::10

HTML HyperText Markup Language. A common coding language used to create Web pages.
HTTP HyperText Transfer Protocol. The protocol for moving hypertext files across the World Wide Web. When you enter a URL in your browser to visit a Web page, an HTTP command is sent to the Web server. This command tells the server to fetch and transmit the requested Web page.
IP Address The unique number assigned to each and every device connected to the Internet (e.g., 10.141.202.111). When you connect to the Internet, your ISP assigns you an IP address for the duration of your connection. DNS converts domain names into IP addresses.
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. For example, to view the man pages for the ls command, you would type the following at a UNIX or Linux command prompt: man ls This would display information on how to use the ls command, including flags and options. Note that the above command, like all commands and file names in UNIX and Linux, is case-sensitive.
MIME Multipurpose Internet Mail Extensions. The standard for attaching non-text files (such as graphics, spreadsheets, word processor documents, sound files, etc.) to email messages.
MPS Managed Private Server. A completely private physical server on which the hosting provider manages operating system and preinstalled software updates and monitors performance, stability and security. An MPS has only one customer per physical server, and MPS customers have root access to their accounts.
MX Record An entry in a domain name system database that directs the routing of mail transfer agents. The MX record is used, for instance, to set which mail server will handle the processing of your e-mail.
Name Server A program that stores and tracks DNS information. Also see: DNS.
Overage When an account exceeds its allotted monthly data transfer limit. For example, if your account allows a maximum of 10 GB of data transfer per month but, at the end of the month, your account transferred 11 GB of data, your account is in overage status.
Parked Domain A domain name that does not have a web page to display.
PGP Pretty Good Privacy. A high-security encryption program for sending encrypted emails.

POP Post Office Protocol. An Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server.
Port A connection point for different protocols to communicate on different machines.
Propagation The process of updating a domain across the world's Internet servers. Propagation can take between three to five days.
Protocol A standard for the exchange of information. There are several different types of protocols (e.g., FTP, TCP/IP) used by various computers and software.
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.
Root The System Administrator or "super user" account on a UNIX or Linux system.
Router A special network system for directing network traffic.
Script A list of commands that can run without user interaction.
Second level domain In the Domain Name System (DNS), the next lower level of the hierarchy beneath the top level domains. For example, the "example" in example.com. 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. It acts as a virtual shopping cart, keeping track of the items visitors have ordered and allowing them to add or remove items. When a visitor decides to "check out" (purchase the items online) the software sends all order information to the merchant.

SQL Structured Query Language. A specialized programming language for sending queries to databases. Many database applications can be addressed using SQL. 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.
TCP/IP Transmission Control Protocol/Internet Protocol. This is the suite of protocols that defines the Internet. Originally designed for the UNIX operating system, TCP/IP software is now available for every major computer operating system. Your computer must have TCP/IP software to be connected to the Internet.
Telnet A program for connecting to shells on remote computers.
Third level domain In the Domain Name System (DNS), the next highest level of the hierarchy below the second level domains. In a domain name, that part of the domain name that appears two segments to the left of the top-level (or first level) domain. For example, the "maps" in maps.google.com.
Top level domain In the Domain Name System (DNS), the highest level of the hierarchy after the root. In a domain name, the top level domain is that part of the domain name that is furthest to the right. For example, the "com" in google.com.
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.
URL Uniform Resource Locator. The standard way to display an address on the World Wide Web (WWW). A URL is accessed through a Web browser and looks like this: http://www.google.com
