Table - A set of data elements that has a horizontal dimension (rows) and a vertical dimension (columns) in a relational database system. A table has a specified number of columns but can have any number of rows. A table is often called a relation. Rows stored in a table are structurally equivalent to records from flat files in that they must not contain repeating fields. In webpage’s it can be as simple as a spreadsheet of rows and columns, or as complex as a set of data within a database.

Tape backup - a recording system using electronic tape to store a copy of data for preservation purposes. If data should need to be restored, then the data can be found on the tape backup. Lunarpages backup data every day on every server.

tcp - (Transmission Control Protocol) one of the main protocols in TCP /IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

Telnet - A terminal emulation program for TCP /IP networks such as the Internet. The Telnet program runs on your computer and connects your PC to a server on the network. You can then enter commands through the Telnet program and they will be executed as if you were entering them directly on the server console. This enables you to control the server and communicate with other servers on the network. To start a Telnet session, you must log in to a server by entering a valid username and password. Telnet is a common way to remotely control Web servers.

Template - A set of pre-designed formats for text and graphics on which new pages and webs can be based. After a page or web is created using a template, you can customize the page or web.

Temporary URL - Lunarpages will create a temporary url for a customer if they request it while their own domain name is being registered and propagated. This is typically done when advanced web hosting functions such as php, jsp, asp, etc are needed immediately or for a testing purpose. The temp url is made into the form of subdomain.lunarpages.net where the customer can choose their subdomain name.

Thunderbird - A remote email client made by Mozilla.

Title - The title bar - the very top of the browser - displays the title of the page. The title of a web page is also displayed in search engine result pages; in minimized window titles at the bottom of the screen; and in lists of bookmarks or favorites.

tracert - a TCP /IP utility which allows the user to determine the route packets take to reach a particular host. Trace route works by increasing the "time to live" value of each successive packet sent. The first packet has a TTL value of one, the second two, and so on. When a packet passes through a host, the host decrements the TTL value by one and forwards the packet to the next host. When a packet with a TTL of one reaches a host, the host discards the packet and sends an ICMP time exceeded. Customers are sometimes asked to perform this function to determine if there is a break in communications between themselves and a remote server such as Lunarpages' servers.

Traffic - the amount of activity over a communication system during a given period of time; "heavy traffic overloaded the trunk lines"; "traffic on the internet is lightest during the night"

Trojan (Trojan horse) - An apparently useful and innocent program containing additional hidden code which allows the unauthorized collection, exploitation, falsification, or destruction of data. Most commonly associated with viruses.

Upload - Transferring a file or files from the user's computer to a remote computer.

Uptime - strangely enough, the opposite of downtime. It is defined as being the time that an item of equipment is in service and operating.

URI - Uniform Resource Identifier - URIs have been known by many names: WWW addresses, Universal Document Identifiers, Universal Resource Identifiers, and finally the combination of Uniform Resource Locators (URL) and Names (URN). As far as HTTP is concerned, Uniform Resource Identifiers are simply formatted strings that identify - via name, location, or any other characteristic - a resource.

URL - Uniform Resource Locator; an address that specifies the location of a file on the Internet (eg, http://www.fsu.edu/library).
Usability - Usability is the measure of how easy it is to use a website. A site would be considered usable if it meets certain criteria, which can include: having logical navigation, adherence to established conventions for the web, and providing an easy to use help section. Many other factors can come into play.

User agent

validation/validator - An automated tool to check that coding used to create web pages is valid. It is important that coding is valid as this can impact on the accessibility of pages. Assistive technology used by disabled users such as screen readers may have problems if coding is invalid. Search engines may also have difficulty indexing pages. Most web editing packages include HTML validators or checkers, alongside spell checkers. Online validators are also available, eg W3C HTML validator and Style Sheet Validator.

Virtual host - A computer which can be forced to respond to multiple IP addresses and provide various services (typically different Web services) on each. Each of these IP addresess (which usually each have their own hostname) operate as if they were separate hosts on separate machines, although they are really all the same host. Therefore, they are called "virtual" hosts. An example of virtual hosting is when an Internet Service Provider "hosts" World-Wide Web and other services for several customers on the same computer but gives the appearence that each of these services use separate servers.

Virus - A virus is a type of program that can replicate itself by making (possibly modified) copies of itself. The main criterion for classifying a piece of executable code as a virus is that it spreads itself by means of 'hosts'. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable disk. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with worms. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms.

Viruses can infect different types of hosts. The most common targets are executable files that contain application software or parts of the operating system. Viruses have also infected the executable boot sectors of floppy disks, script files of application programs, and documents that can contain macro scripts. Additionally, viruses can infect files in other ways than simply inserting a copy of their code into the code of the host program. For example, a virus can overwrite its host with the virus code, or it can use a trick to ensure that the virus program is executed when the user wants to execute the (unmodified) host program. Viruses have existed for many different operating systems, including MS-DOS, AmigaOS, and Mac OS; today, the majority of viruses run on Microsoft Windows.A legitimate application program that can copy itself as a side-effect of its normal function (e.g. backup software) is not considered a virus. Some programs that were apparently intended as viruses cannot reliably self-replicate, because the infection routine contain bugs. For example, a buggy virus can insert copies of itself into host programs, but these copies never get executed and are thus unable to spread the virus. Self-replicating programs that have very limited spreading capabilities because of bugs should not be considered legitimate viruses.

Visits - a complete session of accesses to a certain web server conducted by one person. A visit is concluded when the customer hasn't viewed any page for a certain period of time (60 seconds in most cases).

VOIP - (Voice over Internet Protocol) The technology used to transmit voice conversations over a data network using the Internet Protocol. Such data network may be the Internet or a corporate Intranet.

VPN - (virtual private network) A private network constructed across a public network such as the Internet. A VPN can be made secure, even though it is using existing Internet connections to carry data communication. Security measures involve encrypting data before sending it across the Internet and decrypting the data at the other end. An additional level of security can be added by encrypting the originating and receiving network address.
W3C - The W3C (short for World Wide Web Consortium) is the body that defines standards for many web related languages and technologies. They oversee development of standards for languages such as HTML and CSS . Their site can be found here: http://www.w3.org/
