Active Server
Pages |
A Web server technology from Microsoft that allows for
the creation of dynamic, interactive sessions with the user. An ASP is a Web
page that contains HTML and embedded programming code written in VBScript or
Jscript. It was introduced with Version 3.0 of Microsoft's Internet
Information Server (IIS). When IIS encounters an ASP page requested by the
browser, it executes the embedded program. ASPs are Microsoft's alternative
to CGI scripts and JavaServer Pages (JSPs), which allow Web pages to interact
with databases and other programs. Third party products add ASP capability to
non-Microsoft Web servers. The Active Server Page technology is an ISAPI
program and ASP documents use an .ASP extension. ASP.NET is an enhanced version
of ASP for the .NET platform. See CGI
script, JSP
and ISAPI. |

Anonymous
Connections (FTP) |
An FTP site on the Internet that contains files that can
be downloaded by anyone. The anonymous FTP directory is isolated from the
rest of the system and will generally not accept uploads from users. |
|
Default page |
The web page a web server automatically serves when a
user accesses a web site. This page
may also be referred to as a home page. |
|
DNS |
Name resolution software that lets users locate
computers on the Internet (TCP/IP network) by domain name. The DNS server
maintains a database of domain names (host names) and their corresponding IP
addresses. In this hypothetical example, if www.mycompany.com were presented
to a DNS server, the IP address 204.0.8.51 would be returned. DNS has replaced
the manual task of updating HOSTS files in an in-house UNIX network, and of
course, it would be impossible to do this manually on the global Internet,
given its size. |
|
Formatting |
DOS and
Windows use a file system known as the File Allocation Table (FAT) to keep
track of data on a disk. All floppy disks and hard disks must be initialized
with the FAT before use. This is known as a high-level format. Windows NT can
optionally use its own native format (see NTFS). |
|
FrontPage Server
Extension |
|
|
FTP |
A
protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.).
For example, after developing the HTML pages for a Web site on a local
machine, they are typically uploaded to the Web server using FTP. |
|
Host Headers |
Host name resolution means successfully mapping a host name to an IP address. A host name is an alias that is assigned to an IP node to identify it as a TCP/IP host. The host name can be up to 255 characters long and can contain alphabetic and numeric characters, hyphens, and periods. You can assign multiple host names to the same host. |
|
Internet
Protocol |
Refers
to all the standards that keep the Internet running. The foundation protocol
is TCP/IP, which provides the basic communications mechanism as well as ways
to copy files (FTP) and send e-mail (SMTP). The Web added the HTTP protocol
for downloading Web pages and HTML, XML and XHTML for formatting them. There
are many others and many more are expected, as the Internet has become
"the" arena for global standards. |
|
Network |
A
system that transmits any combination of voice, video and/or data between
users. It includes the cables and all supporting hardware such as bridges,
routers and switches. In wireless systems, antennas and towers are also part
of the network. |
|
Parent Web site |
Webs
site that is one level up from the current web site. These are generally
separated by the /. Example: www.mydomain.com/cars |
|
Partitions |
A
subdivision of a hard disk. The maximum size of a disk partition depends on
the operating system used. |
|
Permissions |
A rule associated with an object (usually a directory,
file, or printer) to regulate which users can have across to the object and
in what manner. |
|
Port |
In
a TCP/IP-based network such as the Internet, it is a number assigned to an
application program running in the computer. The number is used to link the
incoming data to the correct service. Well-known ports are standard port
numbers used by everyone; for example, port 80 is used for HTTP traffic (Web
traffic). |
|
Production Web Server |
A
computer system used to process an organization's daily work. Contrast with a
system used only for development and testing or for ad hoc inquiries and
analysis. |
|
RAID hard drive
Array |
(Redundant
Array of Independent Disks) A disk subsystem that increases performance
and/or provides fault tolerance. RAID is a set of two or more hard disks and
a specialized disk controller that contains the RAID functionality. Developed
initially for servers and stand-alone disk storage systems, RAID is
increasingly becoming available in desktop PCs primarily for fault tolerance.
RAID can also be implemented via software only, but with less performance,
especially when rebuilding data after a failure. |
|
Redundant Power
Supplies |
The installation of
duplicate power supplies that are designed to come into use to keep equipment
working if their counterparts fail. |
|
SMTP Mail |
(Simple
Mail Transfer Protocol) The standard e-mail protocol on the Internet. It is a
TCP/IP protocol that defines the message format and the message transfer
agent (MTA), which stores and forwards the mail. SMTP was originally designed
for only ASCII text, but MIME and other encoding methods enable program and
multimedia files to be attached to e-mail messages. |
|
TCP/IP |
(Transmission
Control Protocol/Internet Protocol) A communications protocol
developed under contract from the U.S. Department of Defense to internetwork
dissimilar systems. Invented by Vinton Cerf and Bob Kahn, this de facto UNIX
standard is the protocol of the Internet and has become the global standard
for communications. |
|
Virtual Server |
With Internet Information Server (IIS), you can create virtual
servers that enable a single server to appear as several servers. By
convention, each domain name (for example, www.company.com) represents an
individual computer. However, it is possible to use a single computer and
make it appear to be not only a primary server (for example, named
www.company.com), but also servers for different departments of your company
(for example, marketing.company.com, sales.company.com, etc.). You can create
virtual servers for these departments with Microsoft Internet Information Server.
You do not need a different computer for each domain name. |
|
Web Folder |
A shortcut to a Web server. When you save a file to a
Web folder, the file is saved on a Web server, not on your computer's hard
disk. You create Web folders by using the Add Web Folder Wizard, which is
located at the root directory of Web Folders in Windows Explorer. You can
also create a Web folder from the Open or Save As dialog box in any Microsoft
Office program. The Web server that you save files to must have Microsoft
FrontPage server extensions installed. |
