Aliased Nameservers An aliased nameserver is a nameserver that has been labeled as yours (the reseller's) despite the fact it actually belongs to your Web hosting provider. This ensures that domains located on your server are listed as "ns.yourservername.com" instead of "ns.yourprovidersname.com". Also see NAMESERVER below.

Apache One of the world's most popular Web server programs, Apache was built by a group of open-source programmers and is often used because of its outstanding performance, strong security features and the fact that it is free. The first version of Apache, based on the NCSA httpd Web server, was developed in 1995. Because it was developed from existing NCSA code plus various patches, it was called a patchy server - hence the name Apache Server.

As a result of its sophisticated features, excellent performance, and low price (it's free), Apache has became the world's most popular Web server. By some estimates, it is used to host more than 50% of all Web sites in the world. Core development of the Apache Web server is performed by a group of about 20 volunteer programmers called the Apache Group. However, because the source code is freely available, anyone can adapt the server for specific needs, and there is a large public library of Apache add-ons. In many respects, development of Apache is similar to development of the Linux operating system. The original version of Apache was written for UNIX, but there are now versions that run under OS/2, Windows and other platforms.

ASP
Active Server Pages (ASP). ASP files, which provide Web developers with an easier, faster and more powerful way to build Web applications, are regular HTML pages with embedded scripts. These scripts can be written in any language and processed by the server when the file's URL is requested. The specification for a dynamically created Web page with an ASP extension contains either Visual Basic or Jscript code. When a browser requests an ASP page, the Web server generates a page with HTML code and sends it back to the browser. So ASP pages are similar to CGI scripts, but they enable Visual Basic programmers to work with familiar tools.

Audio Streaming - The process of providing audio content on a web site. This takes up a large amount of bandwidth, especially if you get a lot of visitors at your site. Some hosts do not allow audio or video streaming because of this.
top

Availability - Refers to the amount of time within a 24 hour period a system is active or available for servicing requests. For example, if a hosting company says it is available 99.9% of the time, they are claiming that your web site will up all the time except for about 8 seconds each day. Over the course of a year, in this example, the hosting company is claiming that your site will only be unavailable (couldn't surf to it) for 48 hours.
top

Backbone - A high-speed line or series of connections that forms a major pathway within a network. The term is relative as a backbone in a small network and will likely be much smaller than many non-backbone lines in a large network. In general, the better the backbone of the hosting company, the better the availability of the web sites that run on their computers.
top

Bandwidth The amount of data that can be transmitted at a given moment to a server. The higher your bandwidth, the larger amount of traffic your site can handle at one time.
top

CGI Short for Common Gateway Interface, A set of rules that describe how a Web Server communicates with another piece of software on the same machine and how the other piece of software (the 'CGI program') talks to the web server. Any piece of software can be a CGI program if it handles input and output according to the CGI standard.

Usually a CGI program is a small program that takes data from a web server and does something with it, like putting the content of a form into an e-mail message or turning the data into a database query.

CGI "scripts" are just scripts which use CGI. CGI is often confused with Perl, a programming language. CGI is an interface to the server from a particular program. Perl is an application of CGI, as well as MIVA, Python, PHP3 and other scripting languages.
top

Cgi-bin The directory on a Web server where CGI scripts are stored.
top

ColdFusion - An application which simplifies database queries by allowing for a simpler programming language to handle functions between the user's browser, the server and the database. After you have developed your web site, you will know whether ColdFusion is a requirement. If you have not used ColdFusion to develop your site, you should ignore this feature.

Co-located hosting This hosting option gives webmasters complete control over their server. You are responsible for providing the physical hardware and network administration; the hosting company will provide you with the rack space, power, security, a defined level of technical support and Internet connection.
top

Control Panel - Control panel refers to a popular graphical user interface for webmasters to manage their website functions such as creation of POP3 email accounts, viewing of web stats, creation of mySQL database, etc.
top

Cookie A text file sent to a user's Web browser from a Web server. Cookies are typically exchanged back and forth between the two in order to prepare custom content for users and to exchange data like registration information.
top

Data Transfer This is the amount of data that is transferred from an account as visitors view the pages of the web site. If you have a web site with lots of video, audio, and images that gets many visitors per day, you would have to make sure that you choose a host that will allow large amounts of data to be transferred. If you choose a host that only allows 200 MB of data transfer per month, and your site transferred 500 MB per month, then the host may stop half of your visitors from viewing your site and you could lose potential customers. Your best bet is to try to find a host that offers unlimited data transfer or at least a Gig of transfer. A gig is more than enough for most web sites. As a general rule, 500 MB of data transfer is equivalent to 20,000 page views.
top

Dedicated hosting A hosting feature that allows a Web site to have its own server. This is more flexible than shared hosting (see below), as webmasters typically have full control over the back end of the server, including choice of OS. Administration, however, is still handled by the hosting company.
top

Diesel Generator A diesel-powered generator used by hosting companies as a back-up source to generate electricity in the event of a power outage.
top

Disk Space Indicates the amount of space on the hard drive that will be available to you on the hosts server to hold your Web site files. Normally because HTML files are small, a Web site (unless it has extensive graphics or database functionality) will be small, as low as 1 or 2 MB in most cases.
A good rule of thumb is to assume approx. 50 KB per page (1 MB = 1000 KB, 1 GB = 1000 MB). 50 KB per page is on the high side so it's a conservative estimate for the average size of a web page.
top

Often hosting companies will charge an extra fee if disk space exceeds the plan limits. If you think this could happen then either go with a higher MB limit from the start or check with the hosting provider to understand their policies on Disk Space. Remember, the addition of a database can significantly increase your requirements for disk space.
top

Domain names Domain names are the word sequences users enter in their URL bar to visit your site. They are attached to a DNS, short for Domain Naming System, which is used to translate numeric addresses (known as IP, or Internet Protocol, addresses) into words. Each site you visit on the net has a numeric IP address behind its name.
top

Firewall A piece of security software designed to protect Web servers. They are typically used to protect sites from hacker attacks/unauthorized access.
top

Flash A popular piece of animation software developed by Macromedia. Flash is widely used on the Web because it requires little bandwidth, therefore making it friendly to users with low or high-speed connections.
top

FrontPage A site design and management tool developed by Microsoft. FrontPage extensions can be thought of as "mini programs" that allow features of a web site created with MS Front Page to operate smoothly. It is possible to use MS Front Page to create a web site and host that site on a server that doesn't offer FP extensions; however some of the powerful features of the program cannot be used in these web sites. See Microsoft's Front Page site for more information. After you design your web site, you will know whether FrontPage extensions will be a requirement.

FTP Short for File Transfer Protocol, A very common method of moving files between two Internet sites. FTP is a special way to login to another Internet site for the purposes of retrieving and/or sending files. There are many Internet sites that have established publicly accessible repositories of material that can be obtained using FTP. By logging in using the account name anonymous, these sites are called anonymous ftp servers.

Gateway
The technical meaning is a hardware or software set-up that translates between two dissimilar protocols. For example Prodigy has a gateway that translates between its internal, proprietary e-mail format and Internet e-mail format. Another, sloppier meaning of gateway is to describe any mechanism for providing access to another system, e.g. AOL might be called a gateway to the Internet.

You can use it to create forms for user interaction or Web pages which require access to the mySQL database backend.
PHP files usually end with the .php extension and can be stored anywhere within the public directory of the web hosting account.
Most web hosting companies provide use of PHP with their accounts. If a company you're looking at does not provide PHP, then you should re-consider the buy as you'll miss out on the ability to run PHP scripts.
top

POP Short for Post Office Protocol. An e-mail protocol that mail software such as Eudora use to communicate with mail servers.
top

Propagation The process whereby the nameservers throughout the Internet have updated their records for a specific domain. For example, if you move your domain from one host to another, it will take around 24 hours or so for the new address to broadcast everywhere. During that 24 hour period, the traffic is decreasing at the old location and increasing at the new location.
top

RAID Short for Redundant Array of Independent Disks, a method of data protection/backup. Data is stored over a number of servers so that information will still be accessible if a piece of hardware/software crashes.
top

Register (Domain Name)
Since every domain is unique, registries have been set up to assign domains to individuals and organizations. When a domain is registered with the appropriate registry, that domain is assigned and becomes no longer available for anyone else to use. Typically, there are registration and renewal fees (local registry fees) associated with the right to use a domain. However, there are some TLDs that are provided at no charge.
top

Registrant (Domain Name)
The entity, organization or individual that will be using the domain name.

top

Registry (Domain Name)
An organization responsible for assigning domain names for the TLD that they manage. Furthermore, it is their responsibility to update the global DNS tables that all nameservers use to resolve domain names. For example, InterNIC is the registry for .COM, .NET and .ORG domain names.
top

Renewal (Domain Name)
Most TLDs need to be renewed at some scheduled yearly interval. This is an opportunity for both the registrant and the registry to update their records as well as collect any applicable renewal fees.
top

Reseller A reseller operates components of a Web hosting operation using services, infrastructure and equipment provided by another Web hosting service.

Shared hosting The most basic of Web hosting types. With shared hosting, numerous Web sites are shared on one server. While an economic solution, they typically cannot handle large amounts of storage or traffic.
top

Shopping cart A program designed to handle the e-commerce section of a Web site. Shopping cart software lets users browse for and purchase products online.
top

SLA SLA refers to Service Level Agreement. Credible web hosting companies have an SLA stating their uptime and downtime policies.
For example, a good SLA should specify that the host will ensure an uptime of above 99.0%. In addition, it should also clearly state the compensation available to clients if the service level falls below the SLA figures.
top

SMTP Short for Simple Mail Transfer Protocol, a protocol used by mail servers to exchange messages with each other. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP. In addition, SMTP is generally used to send messages from a mail client to a mail server. This is why you need to specify both the POP or IMAP server and the SMTP server when you configure your e-mail application.
top

SQL Short for Standard Query Language. A standard protocol used to request information from databases. Servers which can handle SQL are known as SQL servers.
top

SSL Short for Secure Sockets Layer, a protocol developed by Netscape to handle and protect confidential/sensitive information required for e-commerce transactions (like credit card numbers). SSL addresses usually begin with 'https'.

Typically are downloadable movies (video files) that are transmitted over the Internet just like any other kind of static text, graphic or sound file. These downloaded movies arrive at the desktop, are stored and then available to be played. This is the simplest form of video on the Internet and requires no special Internet tools to either server or view. Files of this sort are often Quicktime or MPEG, and have been the most popular form of video on the Internet in recent history.
top

Subdomain Typically known as a "domain within a domain", subdomains are individual Web addresses built upon a pre-existing domain name (such as clientname.yourhostingcompany.com). As a reseller, you will have the option of assigning subdomains to clients if they do not choose to have a domain name.
