ITE8 Chapter 1 Terms

Accelerated Graphics Port (AGP)

• A network-based file system that allows file access over the network.
• A high-speed slot for attaching an AGP video card. AGP has been superseded by PCI.
• A type of software installation in which installation files are stored on a server so that a client computer can access the files remotely to begin the installation.
• A single CPU with two cores, in which both cores can process information at the same time.

adapter

• A component that physically connects one technology to another.
• A basic cmd command for getting help on a specific command.
• A standard interface that connects peripheral devices to a computer; these devices are hot swappable, which means users can connect and disconnect the devices while the computer is powered on.
• An always-on service that uses radio signals for transmitting data and Internet access. A clear path between the transmission tower and customer is required.

adapter card

• A hardware device that takes the data processed from input and passes on the information for use.
• An ultra-small flash memory card designed for use in portable devices such as cameras, MP3 players, and laptops to provide high-capacity memory in a small form factor.
• In Windows Device Manager, an option to remove a driver.
• A device that increases the functionality of a computer by adding controllers for specific devices or by replacing malfunctioning ports.

Advanced Technology (AT) power supply

• An impact printer with print heads that strike an inked ribbon, causing characters to be imprinted on the paper.
• The original power supply for legacy computer systems; now considered obsolete.
• A Windows console that enables management of many aspects of a computer and remote computers in one tool.
• A newer Bluetooth technology geared toward devices that have limited power and that do not need high data transfer rates; has four different data rates to accommodate a variety of transmission ranges.

alternating current (AC)

• A lock that uses a combination of mechanisms.
• A remote authentication AAA server that performs authentication on behalf of network devices. Rather than the network devices storing and validating user credentials directly, they pass the request to the AAA server and forward the response to the user.
• Memory that is usually used for cache that uses little power and is much faster than dynamic RAM.
• A current that changes direction at a uniformly repetitive rate. This type of electricity typically is provided by a utility company and is accessed through wall sockets.

AT Extended (ATX)

• A computer desktop power supply form factor. It is an updated version of the AT but still considered to be obsolete.
• A security policy item that identifies how remote users can access a network and what is accessible via remote connectivity.
• A model that consists of layers that perform functions necessary to prepare data for transmission over a network.
• A communication protocol that enables two electronic devices to establish communication when they are close to each other.

ATX12V

• A network layer device that forwards data packets between networks. Routers use IP addresses to forward traffic to other networks.
• Remote Desktop Protocol, a desktop protocol developed by Microsoft to provide remote access to the graphical desktop of a remote machine.
• Technology that enables a PC to predict the future failure of hard disk drives.
• The most common power supply on the market today. It includes a second motherboard connector to provide dedicated power to the CPU.

audio

• A Linux shell interpreted language.
• A client-side scripting language that runs in a browser.
• A fiber-optic connector, sometimes referred to as square connector or standard connector, that uses a push/pull mechanism to ensure positive insertion. This connector type is used with multimode and single-mode fiber.
• The sound system that comes with or can be added to a computer. audio port A port used to connect audio devices to a computer.

augmented reality (AR)

• A Windows setting that enables you to prevent others from easily copying the content in a document by printing to an image file format, such as JPG or TIFF.
• Computer technology that creates a simulated environment as it superimposes images and audio over the real world in real time.
• A Windows utility that monitors programs on the computer and warns users when actions might present threats to the computer.
• A specialized chip installed on a motherboard and designed to secure hardware by storing encryption keys, digital certificates, passwords, and data.

barcode scanner or price scanner

• A traditional magnetic storage disk device, with speed measured in revolutions per minute (RPM).
• An army of compromised hosts.
• A scanner that reads the information contained in the barcodes affixed to most products. These scanners can be handheld, wireless devices, or a stationary device.
• A Windows console that enables management of many aspects of a computer and remote computers in one tool.
