Browsing/searching: Browsing involves following links on a page to shop around and explore what's there, a bit like window-shopping. Searching is when you find a search box on a particular web page, enter terms, and find all occurrences of the terms throughout the site. When you browse, you have to guess which words on the page pertain to your interests. Searching is usually more efficient, but sometimes you find things by browsing that you might not otherwise find.
Chain-letter worms: Computer viruses characterised by their ability to link to the recipients email address book and forward themselves to the list, thus forcing the recipient to unwittingly pass on the virus to others in a series of chain-letter style attacks. The virus therefore has potential to spread exponentially across the globe.
Client/Server: A client/server system is one where the user�s computer (the client) works with another computer (the Server) in order to achieve the desired results. The World Wide Web is a Client/Server system whereby the browser on the client computer requests Web pages from the Web Server machine.
Co-located/co-location: Most often used to refer to having a server that belongs to one person or group physically located on an Internet-connected network that belongs to another person/group or company. Usually this is done because the server owner wants their machine to be on a network provider�s high-speed Internet connection and/or they do not want the security risks of having the server on their own network. Typically co-location services offer fully managed options.
Coldfusion: A database tool for the World Wide Web (WWW). Coldfusion allows databases to have a WWW interface, so a database can be queried and updated using a web browser.
Connection speeds: The speed at which electronic data travels between computers and networks, measured in kilobits and Megabits per second (kb/s and Mb/s). The cost of access increases with the connection speed selected, up to a maximum (with second generation SDSL and leased lines) of 2Mb/s.
Core network: A set of gateways (routers) to a network system, which forms a central part of Internet routing. The Trinit� core network is a mature high-speed international network with independent connections to Telehouse London, Telehouse New York and Newark, resilient 1Gb/s connectivity to LINX and 100Mb/s connectivity to the LoNAP peering points. Usage is constantly monitored and the network is maintained at a maximum of 50% capacity to ensure it develops in tandem with customer growth and technological development.
Cracker: An individual who attempts to access computer systems without authorization. These individuals often have malicious intentions or commercial sabotage in mind.
Data: A stream of binary bits representing particular information produced by a computer, workstation or other electronic sources.
Data Centre: An area or location designated for the storage of data, often including servers and computers, their databases, software applications and programs. Nildram�s Data Centre, for example, houses its own and its clients� servers as well as a host of software application servers and services which clients may access via the network. Data from resulting communications is then stored and backed up in the Data Centre.
