A Record Forms part of a Zone File. The Address (A) record associates a hostname with an IP address.
Anonymous FTP A method for allowing people to up/download files using FTP (File Transfer Protocol) whereby they do not have to identify themselves. Usually the username “anonymous” is used, and either the Password is provided by the FTP server, or anything may be used.
Anonymous FTP is generally avoided by many administrators as it may pose security issues by allowing unidentified users access to a server. We do not support this type of FTP connection on our hosting accounts.

Apache A popular Web server (HTTP server), providing a full range of Web server features, including CGI, SSL, and virtual domains. Apache also supports plug-in modules for extensibility.
Applet A small Java program which is embedded in a webpage. Javavirtual machines are normally installed into Web browsers so they can then run the applets to perform interactive graphics, games etc. An applet is also a more general term for a small program designed to do a very specific task.
ASCII American Standard Code for Information Interchange. A code for information exchange formed by a string of 7 binary digits, each representing a character.
ASP Active Server Page (ASP) is a server-side scripting technology that can be used to create dynamic/interactive Web applications. An ASP page is a HTML page that contains server-side scripts that are processed by a Web server before being sent to the user’s browser. Please note that we do not support this type of script.
Attachment File sent encoded as part of an e-mail, but intended to be viewed separately. These are typically binary rather than text files, examples being audio or video clips, word processor documents or spreadsheets. The total size of the encoded e-mail including any attachment is usually limited by the sending and/or receiving mailservers.
Audio Streaming Some audio and video file formats allow the file to be streamed such that it will start playing before the entire file has downloaded. This usually requires a separate helper application alongside the browser on the client computer. Examples of these formats include Quicktime for video and Real Audio for audio.
Autoresponder Means of setting a standard e-mail to be automatically sent back to a someone who sends an e-mail to a given address. This might be to acknowledge receipt and/or thank the sender for their interest, could provide details on a particular product or service, or could advise of absence from an office over a certain period.
AVI Acronym for Audio Video Interleave. High quality format for video files. Not compressed so files can be quite large. Filenames normally end in .avi. Does not allow streaming.
Backbone A backbone is a larger transmission line that carries data gathered from smaller lines that interconnect with it. The connection points are known as network nodes or telecommunication data switching exchanges (DSEs).
Backup Facility to regularly copy files in an account’s website space to a DailyDrive server, allowing the user to restore lost files.
Bandwidth The amount of data passing through a connection over a given time. It is usually measured in bps (bits-per-second) or Mbps.
Banner Graphic image on a web page. This may be part of the internal site design or for external advertising. iWebServices offers a CGI script which will allow insertion of banner advertisements into a web page.
Bit Binary digit. A bit is an electronic signal which is either .on. (1) or .off. (0). It is the smallest unit of information the computer uses. There are 8 bits in 1 byte.
Blog The name for a web based log (an online journal or diary). Often the term ‘blog’ is used to avoid confusion with actual server logs (i.e. error logs or similar).
BMP Short for bitmap (an image format). BMP files are usually not compressed so they are typically much larger than compressed image file formats such as JPEG or PNG. Filenames end in .bmp
Body tag HTML tag used to denote body text and other elements within a web page.
Bps Bits per second (abbreviated bps or bit/sec). A common measure of data speed for computer and network carriers. As the term implies, the speed in bps is equal to the number of bits transmitted or received each second. Please note a ‘bit’ is always expressed in lowercase (bps) whereas a ‘byte’ is expressed as Bps.
Broadband A type of data transmission in which a single medium (wire) can carry several channels, as opposed to Baseband (e.g. dial-up Internet access) where only one channel can be carried. Broadband offers Internet users much faster speeds and often a permanent Internet connection.
Browser A program such as Microsoft’s Internet Explorer or Mozilla’s Firefox that reads HTML and other code to allow users to view web pages.
Bulletin Board A topic based online notice/discussion board, where users can post messages and/or reply to existing messages. Information is stored in a database and usually there are administrators or moderators who maintain the board.
Byte A unit of data that is eight binary digits (bits) long. A byte is the unit most computers use to represent a character such as a letter, number, or typographic symbol.

Cache A place to temporarily store data. For example, when a user visits a webpage then that page may be cached on the user’s local machine. When the user revisits the page, the browser loads the page from the cache rather than from the actual website. This saves time and reduces strain on both the local machine and the web server the page is hosted upon. However this can mean the user may not see recent changes and will need to refresh/reload the page or empty their cache. Please note that ISP’s can also cache pages.
Camino Web browser created by Mozilla for Apple Macs, which is designed to integrate well with the Mac interface.
Campaign Term used within the e-mail marketing feature available from the control panel for many account types. This refers to a newsletter or ‘mailshot’ which can be configured to have a specific format to be sent out at a certain time.

Command Prompt Interface to enter text commands on a computer using a keyboard. Even though many computers emphasise graphical interfaces and applications in everyday use, almost all will still include some text command functionality. This can take different forms, there being multiple versions or ‘shells’ on UNIX -like systems such as Linux. On Linux servers, text commands are the main method of operation.

On typical Windows computers, this is sometimes referred to as a DOS prompt. A command prompt box is available as a ‘command prompt’ option within the start menus accessories, or by entering ‘cmd’ within the start menus ‘run’ box.

Cookie A small piece of information that is automatically stored on a client computer by a web browser and referenced to identify repeat visitors to a web site and to tailor information in anticipation of the visitor’s interests (e.g. usernames, passwords, display settings). Cookies have been objected to by some of the Internet community if used without a user’s prior consent.

Footer Section at the bottom of a web page, which can in various ways be set to be the same for different pages to ensure a consistent look and feel. Among others, this may be done in the web design program as a template, or using an SSI link to a separate HTML file, or using a frame.
Form A part of a web page which allows someone to enter (typically by checkboxes, Radio Buttons, drop-down boxes, single-line text boxes or text area boxes) and then have it submitted to a separate script to be processed. Typically this would submit to formmail which would create an e-mail containing the entered details and send to a recipient (often the site administrator).
Formmail Script which can be installed to process the results of a form submission and send an e-mail containing the results to an e-mail address.

Forum Script(s) on website which form a discussion area for multiple readers browsing the site. These allow reading, creating and editing discussion ‘threads’ or ‘topics’. In some cases submitting some personal contact details is necessary to access some or all features, to discourage misuse of the forum.
Frame HTML layout tags can be used to divide up a page into separate areas or frames which will not be moved out of site when the user scrolls around the page. This can be useful for headers, footer or sidebars with menus or information which is intended to always be on display. Frames are now used less than in the past since they can cause confusion over links and there are other more flexible ways to achieve similar effects.
Frontpage Website design and publishing program by Microsoft which for full functionality uses special files (‘extensions’) on the web server. Please note that we do not support these extensions. It is still possible to use Frontpage to design a site and then publish (upload) by FTP protocol to our web servers.

GUI Graphical User Interface. A user-friendly display for controlling/manipulating data or executing commands. Most common examples are control panels with simple buttons for creating >e-mail addresses or users, thus meaning the user does not have to run commands manually on a server. Hardware The physical components of a computer are termed hardware, as opposed the programs that run on it which are considered to be software. A common rule is that if something on a computer can be touched it is hardware. For instance an installation CD is hardware but the programs it contains are software.

With IMAP, you can view just the heading and the sender of the e-mail and then decide whether to download the mail. IMAP is used for web-based e-mail readers. The main feature of IMAP is that folders are stored on the server and you can select more than just the inbox folder. POP3 only allows access to the inbox.
Index Page First page to be displayed when browsing to a domain name or a subdirectory of a domain name. The web server (apache) will be configured to look for valid index page filenames in a given order, so if index.html is present it might be used in preference to default.html or index.cgi, for example.
