XMS memory

To create or change a program information file (PIF)

Prior to creating or making changes to the PIF, please review the MS-DOS-based program documentation. Changing the PIF affects how the program interacts with Windows. The program might only work

XON/XOFF flow control

Flow control

There are six different links involved in a connection: transmitting computer to transmitting modem, transmitting modem to receiving modem, receiving modem to computer, and the reverse of all three links. They can all have different data transmission rates. When the receiving modem is temporarily unable to

Define Key?

In Registry Editor, a folder that appears in the left pane of the Registry Editor window. A key can contain subkeys and value entries. For example, Environment is a key of HKEY_CURRENT_USER.
In IP security (IPSec), a value used in combination with an algorithm to encrypt or decrypt data. Key settings for IP security are configurable to provide greater security.

International Telecommunication Union - Telecommunication [Standardization Sector] (ITU-T)

The sector of the International Telecommunication Union (ITU) responsible for telecommunication standards.
ITU-T replaces the Comite Consultatif International Telegraphique et Telephonique (CCITT). Its responsibilities include standardizing modem design and operations, and standardizing protocols for networks and facsimile transmission. ITU is an international organization within which governments and the private sector coordinate global telecom networks and services.

Infrared Port

An optical port on a computer that enables communication with other computers or devices by using infrared light, without cables. Infrared ports can be found on some portable computers, printers, and cameras.

Infrared Network Connection

A direct or incoming network connection to a remote access server using an infrared port.

Infrared File Transfer

Wireless file transfer between a computer and another computer or device using infrared light.

IEEE 1394 connector

A type of connector that enables you to connect and disconnect high-speed serial devices. An IEEE 1394 connector is usually on the back of your computer near the serial port or the parallel port.

If a device is IEEE 1394 compatible, you can connect the device to the IEEE 1394 connector while the computer is running and Windows will detect the device and inform you when it is ready for use. Similarly, you can unplug the device while the computer is running, but you should use the Add Hardware Wizard to inform Windows that you are unplugging the device. Windows will then inform you when the device can be unplugged from the computer.

The IEEE 1394 bus is used primarily to connect high-end digital video and digital audio devices to your computer; however, some hard disks, printers, scanners, and DVD drives can also be connected to your computer using the IEEE 1394 connector.

Hypertext Markup Language (HTML)

A simple markup language used to create hypertext documents that are portable from one platform to another. HTML files are simple ASCII text files with codes embedded (indicated by markup tags) to denote formatting and hypertext links.

Define Hyperlink?

Colored and underlined text or a graphic that you click to go to a file, a location in a file, an HTML page on the World Wide Web, or an HTML page on an intranet. Hyperlinks can also go to newsgroups and to Gopher, Telnet, and FTP sites.

In Windows folders, hyperlinks are text links that appear in the folder's left pane. You can click these links to perform tasks, such as moving or copying a file, or to go to other places on your computer, such as the My Documents folder or Control Panel.

What is Hub?

The position of a color along the color spectrum. For example, green is between yellow and blue. This attribute can be set using Display in Control Panel.

DVD Dual-layer recording

Dual-layer recording (sometimes also known as double-layer recording) allows DVD-R and DVD+R discs to store significantly more data—up to 8.5 gigabytes per disc, compared with 4.7 gigabytes for single-layer discs.[22] Along with this, DVD-DLs have slower write speeds as compared to ordinary DVDs. When played, a slight transition can sometimes be seen in the playback when the player changes layers. DVD-R DL was developed for the DVD Forum by Pioneer Corporation; DVD+R DL was developed for the DVD+RW Alliance by Philips and Mitsubishi Kagaku Media (MKM).[23]

A dual-layer disc differs from its usual DVD counterpart by employing a second physical layer within the disc itself. The drive with dual-layer capability accesses the second layer by shining the laser through the first semitransparent layer. In some DVD players, the layer change can exhibit a noticeable pause, up to several seconds.[24] This caused some viewers to worry that their dual-layer discs were damaged or defective, with the end result that studios began listing a standard message explaining the dual-layer pausing effect on all dual-layer disc packaging.

DVD recordable discs supporting this technology are backward-compatible with some existing DVD players and DVD-ROM drives.[23] Many current DVD recorders support dual-layer technology, and the price is now comparable to that of single-layer drives, although the blank media remain more expensive. The recording speeds reached by dual-layer media are still well below those of single-layer media.

Dual layer DVDs are recorded using Opposite Track Path (OTP).[25] DVD-ROM discs mastered for computer use are produced with track 0 starting at the inside diameter (as is the case with a single layer). Track 1 then starts at the outside diameter. DVD video discs are mastered slightly differently. The video is divided between the layers such that layer 1 can be made to start at the same diameter that layer 0 finishes. This speeds up the transition as the layer changes because although the laser does have to refocus on layer 1, it does not have to skip across the disc to find it.

Host Name

The DNS name of a device on a network. These names are used to locate computers on the network. To find another computer, its host name must either appear in the Hosts file or be known by a DNS server. For most Windows computers, the host name and the computer name are the same.

Host Definition

A Windows computer that runs a server program or service used by network or remote clients. For Network Load Balancing, a cluster consists of multiple hosts connected over a local area network (LAN).

Define Hive

A section of the registry that appears as a file on your hard disk. The registry subtree is divided into hives (named for their resemblance to the cellular structure of a beehive). A hive is a discrete body of keys, subkeys, and values that is rooted at the top of the registry hierarchy. A hive is backed by a single file and a .log file, which are in the systemroot\System32\Config or the systemroot\Profiles\username folders.
By default, most hive files (Default, SAM, Security, and System) are stored in the systemroot\System32\Config folder. The systemroot\Profiles folder contains the user profile for each user of the computer. Because a hive is a file, it can be moved from one system to another. However, you must use the Registry Editor to edit the file.

A chart consisting of horizontal or vertical bars, the widths or heights of which represent the values of certain data.

High Contrast

A display feature that instructs programs to change the color scheme to a high-contrast scheme and to increase legibility whenever possible.

Hibernation

A state in which your computer shuts down after saving everything in memory on your hard disk. When you bring your computer out of hibernation, all programs and documents that were open are restored to your desktop.

Hexadecimal

A base-16 number system represented by the digits 0 through 9 and the uppercase or lowercase letters A (equivalent to decimal 10) through F (equivalent to decimal 15).
