The following terms are relevant to the Sun WebServer product.
Domain Name
A name that identifies a logical group of computers. It is a text string composed of letters (a-z and A-Z), digits (0-9) and hyphens (-) (for example, eng). A fully-qualified domain name is composed of the local domain and all of its ancestor domains leading to the root domain, separated by periods and ending in a period (for example, eng.sun.com.). A partially-qualified domain name is the local domain name and some number of ancestor domains separated by periods (for example, eng.sun). When a partial domain name is used, it is assumed to be within the current domain or within one of the ancestor domains of the current domain.
DNS
Domain Name System. A network information service that provides information about hosts within the domain name system. It is mainly used for name resolution, that is, to provide host addresses that correspond to host names. It can also be used to provide other information about hosts such as aliases or mail servers.
E-mail Address
Electronic Mail Address. An e-mail address is composed of three parts: the user name (the name of the person who receives the mail), the host name (the system on which that user has an account) and the domain name (the domain in which the system resides). The user name is separated from the host name by an at sign (@). The host name and domain name are separated by a period (for example, user@host.domain.com).
Ethernet
A network protocol that broadcasts information to all the hosts on the network. The information is accepted by the intended recipients and discarded by the other hosts.
FTP
File Transfer Protocol. A protocol that allows files to be copied between systems connected to a TCP/IP network independent of the operating systems or architectures of the hosts involved in the file transfer.
Gateway
A communications device or program that passes data between networks having similar functions but dissimilar implementations.
Host Address
An assigned number that uniquely identifies each computer connected to a TCP/IP network. The address consists of two parts: a network number and a host number. The network number identifies the network to which the computer is connected and the host number identifies the computer on that network. The host address is composed of four integers separated by periods. The first integer must be in the range 0-223, the second and third integers in the range 0-255 and the fourth integer in the range 1-254 (for example, 129.144.0.1).
Host Name
The name of a computer within the local domain. It is a text string of up to 24 characters composed of letters (a-z and A-Z), digits (0-9) and hyphens (-). The last character may not be a hyphen.
HTML
Hypertext Markup Language. It is used to format hypertext documents. Hypertext documents have text that contains links to other documents or to images, sound, graphics, or video files.
HTTP
Hypertext Transport Protocol. It is used to transmit and display hypertext documents. HTTP capitalizes on the fact that navigation information can be embedded directly in the documents. Thus, the protocol itself does not have to support full navigation features like the FTP protocols do. Because HTTP has low overhead, HTTP servers are commonly used for serving hypertext documents.
HTTPD
Hypertext Transport Protocol Daemon. It is the software component of a Web server. Using the HTTPD, the SWS server makes its administration tools available to clients on the LAN.
Internet
A global collection of networks connecting a wide range of computers using a common protocol to communicate and shared services.
Internet Service Provider
A company that provides an Internet connection by using its own computer system as a conduit to the Internet. The service provider generally has a direct Internet connection; the client typically connects to the service provider with a dial-up connection.
IP Address
Internet Protocol Address. An assigned number that uniquely identifies each computer connected to a TCP/IP network. The address consists of components that identify the individual computer as well as the network and subnetwork to which it belongs.
Netmask
A mask used to determine the network address from a host address. A netmask is composed of four integers in the range 0-255 separated by periods. When a netmask is expressed in binary notation, it must be a contiguous sequence of "ones" followed by a contiguous sequence of "zeroes" (for example 255.255.128.0).
Router
Network hardware which connects two or more networks and routes data among them.
Service provider
A technical expert who is proficient in hardware and/or software service, including installation, configuration, troubleshooting, and repair. The service provider may be part of the customer staff, or affiliated with an authorized reseller, or an independent contractor.
Software Package
A collection of files and directories required for a software product. A complete software product can be made up of several packages.
URL
Uniform Resource Locator. The addressing system used by clients to request web documents from servers. The format of a URL is [protocol:][//system[:port]]/[document] (for example, http://www.sun.com/).
User Name
The name that the computer uses to identify a particular user. It is a text string of up to eight characters composed of letters (a-z and A-Z), digits (0-9), hyphens (-), and underscores (_). The first character must be a letter.
WWW
This stands for World Wide Web. It is a collection of systems on the Internet that contain hypertext documents that are accessible using HTTP and are displayed as "Web pages" by "Web servers."
