Glossary Here is a glossary of words that are relevant to Haxial, with definitions generally from a Haxial perspective. If the word you are looking for is not here, you can contact Haxial and ask for it to be added. Client A computer program that requests a service from another computer which is running the corresponding server program. Servers and clients are paired, meaning that if a client is to successfully communicate with a server, it must be the same type of client (for example, KDX), or at least compatible. See also Server. Clipboard Also known as copy & paste. The clipboard is a place in your computer system where you can copy things to, such as text, pictures, etc. Once you have copied something to the clipboard, you can then "paste" it somewhere, and the copied material appears where you pasted it. The clipboard is very useful for transferring information from one program to another, or from one document to another. Connect To establish a connection between 2 computers on the Internet or other network. The connection is then used for sending and receiving data. See also Disconnect. Disconnect To break/terminate a connection between 2 computers on the Internet or other network, which was being used for sending and receiving data. See also Connect. DNS Domain Name System. The Internet uses numeric addresses (see definition for IP Address), but these are difficult for humans to remember. The DNS allows us to use human-friendly text addresses known as DNS Addresses or domain names, such as "www.haxial.com". Behind the scenes, when you use a DNS Address, it is translated by the Domain Name System to a numeric IP Address. Download If you download a file, it means that you are copying/transfering that file from a computer on the Internet (or other network) to your computer. Download also means receiving data. See also Upload, which is the reverse operation. Dynamic IP Address The Internet address of either a client or server that is changed by the Internet Service Provider (ISP) each time that the computer establishes a connection to the Internet. Internet An international worldwide computer network. Formed from the words "International Network." Intranet A privately owned network where access is usually restricted to members or employees of the organization that owns it. IP Address An IP Address is an... address. Yes, I really do mean an address, just like a street address: 12 Main Street, Paris. The difference is that while a street address identifies a location in real life, an IP Address identifies a location in the virtual world on the Internet. Indeed, IP Address means "Internet Protocol Address". An IP Address looks something like "200.123.62.280". You can also think of it as similar to a phone number. ISP Internet Service Providers are the companies providing our connections to the Internet, whether it is via dialup connection, cable, DSL or satellite. LAN Local Area Network. A type of network (see definition for Network) which is geographically limited to a small area (for example, to within a one kilometer radius, or within a home, office, or building). A LAN may also be connected to a bigger network, such as the Internet. Network A system that links together multiple computers (and perhaps other devices) so that they can communicate with each other (send and receive information). Port Number If you see an address like 66.33.209.103:10200 or haxial.com:500, then the port number is the number after the colon ':'. So in those examples, the port numbers are 10200 and 500 respectively. Port numbers are generally used to distinguish between the different services/programs that may be running on a computer. You can think of this like a block of apartments/units which all have the same street address, so in order to distinguish between the different apartments, you write an address like: Apartment 5, 12 Main Street. Protocol A procedure for controlling the communication between two programs on different computers on a network. In some ways, it is similar to a language. For example, if two programs do not "speak" the same protocol, then they cannot communicate with each other. Server A "Server" is a computer program which provides some service to other programs which are known as clients. Servers usually run continuously 24 hours a day, 7 days a week. The service is provided via a network such as the Internet or an Ethernet LAN, using a special network protocol that is tailored to the specific services being provided. Servers are often passive entities, doing little or nothing until a client connects and requests service. "Server" is also used to refer to the computer which is running the server program. See also Client. Static IP Address The Internet Protocol address of either a client or server that is always the same, and not changed by the Internet Service Provider (ISP) each time that the computer establishes a connection to the Internet. Usually cable connections are static, as they maintain a connection all the time. Upload If you upload a file, it means that you are copying/transfering a file on your computer to another computer on the Internet (or other network). Upload also means sending data. See also Download, which is the reverse operation. URL Uniform Resource Locator. A standard way of specifying the location of an object, typically a web page, on the Internet. Example:   http://www.haxial.com/faq/   It is in this format:   protocol://address/path/ User A "User" is a person who is using a computer or a program (as opposed to a programmer, who actually creates the program in the first place). A user may also be a person who has an account at a server, but is not an administrator. Copyright 2003 Haxial Software.
