Perl (Practical Extraction and Report Language)
Perl is an interpreted language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. It's also a good language for many system management tasks.
PHP
PHP is another scripting language. Like ASP, it's commands are embedded within the HTML of a web page. The commands are executed on the web server, making it browser independent. The web browser only sees the resulting HTML output of the PHP code.

Post Office Protocol (POP)
This is a method of retrieving e-mail from an e-mail server. Most e-mail applications (sometimes called an e-mail client) use the POP protocol, although some can use the newer IMAP (Internet Message Access Protocol). There are two versions of POP. The first, called POP2, became a standard in the mid-80's and requires SMTP to send messages. The newer version, POP3, can be used with or without SMTP. The newest and most widely used version of POP email is POP3 email. You will see the term POP3 in most of the web hosting plans available today.

Price
The monthly amount that you will have to pay a hosting company to provide the hosting services requested. Paying monthly is normally perfectly acceptable, but discounts may be available by paying quarterly or annually.

Reseller Plans
Many hosting providers allow you to be a reseller of hosting space earning a commission off of each sale. If you intend to be a provider of hosting services, you should investigate this option as you decide where to host your web site. Many hosting companies offer discounts (in addition to revenue opportunities) to companies that wish to remarket their web hosting services.

Root Server
A machine that has the software and data needed to locate name servers that contain authoritative data for the top-level domains.

Setup Fee
Some hosting companies charge a one time setup fee to set up your hosting account. It is worth to also take this into account when looking at the monthly fee.

Server
A computer, or software package, that provides a specific kind of service to client software running on other computers. The term can refer to a particular piece of software, such as a WWW or HTTP server, or to the machine on which the software is running. A single server machine could have several different server software packages running on it, thus providing many different servers to clients on the network. More specifically, a server is a computer that manages and shares network resources.

Shell Account
Something experienced computer users often request. Permits you to edit your files online in real-time, rather than making changes to your site offline and then uploading the changes. Unless you intend to manage the web server your site runs on, a shell account should not be needed.

Simple Mail Transfer Protocol (SMTP)
The main protocol used to send electronic mail on the Internet. Most Internet email is sent and received using SMTP. SMTP consists of a set of rules for how a program sending mail and a program receiving mail should interact.

Server Side Includes (SSI)
Commands that can be included in web pages that are processed by the web server when a user requests a file. The command takes the form <!--#include virtual="/path/to/file"-->. A common use for SSI commands is to insert a universal menu into all of the pages of the web site so that the menu only has to be changed once and inserted with SSI instead of changing the menu on every page.

Secure Socket Layer (SSL)
A protocol designed by Netscape Communications to enable encrypted, authenticated communications across the Internet. It is used mostly (but not exclusively) in communications between web browsers and web servers. URL's that begin with "https" indicate that an SSL connection will be used. SSL provides 3 important things: Privacy, Authentication, and Message Integrity. In an SSL connection each side of the connection must have a Security Certificate, which each side's software sends to the other. Each side then encrypts what it sends using information from both its own and the other side's Certificate, ensuring that only the intended recipient can decrypt it, and that the other side can be sure the data came from the place it claims to have come from, and that the message has not been tampered with.

Shopping Cart Software
A software program which acts as a "virtual store front". Such software typically allows a web site user to create and manage a virtual shopping cart to which items can be added or removed. Once a customer is ready to "check out", this same Shopping Cart Software typically includes interfaces to allow customers to pay with their credit card directly on the site. Shopping Cart Software is critical for those web sites that intend to sell products and services directly over the Internet without human intervention.

Statistics
Many hosting companies run software on their web servers that collect usage information about your web site and compile it in a user-friendly, easy-to-read format for you to analyze trends about your web site. Having access to statistics is critical if you need to know how many visitors are coming to your site, which web pages receive the most attention, and how much time people actually spend browsing your site.

Support
Telephone or e-mail technical support provided to a web hosting company's customers. When there's a problem with your site or your e-mail, you want to be able to get an answer promptly by e-mail or on the phone. Some hosting companies offer email only support, telephone support, or a combination of both. Some hosting companies provide 24hr 7 days a week support (24/7). This is important if your site is an e-commerce site with a lot of daily visitors.

TCP/IP
This is a set of communications protocols to connect hosts on the Internet.

Unix
A computer operating system designed to be used by many people at the same time (it is multi-user) and has TCP/IP built-in. It is the most common operating system for servers on the Internet.

Uniform Resource Locator (URL)
The standard way to give the address of any resource on the Internet that is part of the World Wide Web (WWW). www.adult-hosting-companies.com is an example URL.

Unique IP Address
In many hosting plans, you share an IP address and you will be able to view your site through your domain name only. Obtaining a unique IP address (see IP Address) provides a one-to-one relationship between your domain name (www.yourname.com) and an IP address.

Video Streaming
The process of providing video data or content via a web page.

Virtual Server
A web server which shares its resources with multiple users. It's another way of saying that multiple web sites share the resources of one server. If you do not need your own web server (i.e. your own server class computer), you will use a virtual server to host your web site.
