Memory, particularly RAM, temporarily holds data and instructions that the CPU needs for immediate processing, enabling quick access and operation.

Keyboard, Mouse, and Card reader are all common input devices that allow users to send data and commands into a computer system.

The correct answer is A computer used for one specific purpose.

In computer architecture and operational design, a dedicated computer refers to a system engineered, optimized, and allocated to execute a single, predefined task or system function. Unlike general-purpose personal computers that dynamically switch between word processing, gaming, and web browsing, dedicated systems feature hardwired or highly specialized software configurations tailored for maximum efficiency in one domain. Classic examples include embedded computing systems found inside modern medical equipment, automated teller machines (ATMs), industrial robotic controllers, and automotive engine control units (ECUs).

The remaining distractor options confuse operational dedication with user access, software limitations, or network topology. For instance, a system used by a single individual is classified as a personal computer (PC) or single-user workstation, not a dedicated computer. Similarly, running a singular application profile or connecting to an isolated, high-bandwidth dedicated network describes software ecosystem restrictions and networking infrastructure, rather than the intrinsic architectural purpose of the machine. Therefore, option one is the only definition that captures the true engineering essence of a dedicated computing system.

Optical Character Recognition (OCR) is a technology specifically designed to directly convert scanned images of printed text into machine-encoded text data.

Tape, Hard Disk, and Floppy Disk are all examples of storage devices used to permanently save and retrieve digital data in a computer system.

Employee address is an example of non-numeric data because it consists of characters and symbols, not solely numerical values used for calculations.

A standard 3.5-inch floppy disk commonly had a storage capacity of 1.44 megabytes, which was widely used for data transfer.

The user interface provides the means for users to interact with the operating system, controlling how commands are given and information is displayed.

A hybrid computer combines features of both analog and digital computers, processing both continuous analog signals and discrete digital data efficiently.

A scanner is a light-sensitive input device that converts physical documents, drawings, or images into digital data for computer processing and storage.

Routers primarily operate at Layer 3, the Network Layer, of the OSI model, handling logical addressing and routing data packets between different networks.

"Narrow" is a specific preset option for page margins, defining the amount of white space around the content on a document page.

The kernel is the fundamental core of an operating system, responsible for managing system resources and facilitating communication between hardware and software.

The "Edit" option is not typically associated with a spelling dialogue box, which primarily offers ignore, change, or add options for corrections.

Mbps (Megabits per second) is the standard unit of measurement used to quantify the speed of an internet connection, representing data transfer rate.

The correct answer is AVI.

In computer science and multimedia analytics, evaluating streaming technologies requires analyzing data types and container properties. The question asks for a format capable of transmitting streaming video data. Among the choices provided, AVI (Audio Video Interleave) is the only multimedia container format engineered to store both video and audio streams simultaneously. Developed by Microsoft, AVI structures files so that audio and video data segments alternate sequentially, allowing media players to decode and sync multimedia components dynamically during web playback or progressive downloads.

The alternative distractor options fail to satisfy the core requirement because they are strictly limited to audio architectures. For example, MP3 (MPEG-1 Audio Layer III) is a lossy compression format designed exclusively for acoustic data. Similarly, WMA (Windows Media Audio) and WAV (Waveform Audio File Format) are dedicated digital audio formats developed for sound reproduction and storage. None of these three options possess the technical capacity to encapsulate or transmit structural video frames. Therefore, AVI is the only logically viable option that satisfies the criteria of the prompt.

User-developed instructions or automated sequences of commands in Excel are specifically known as Macros, simplifying repetitive tasks.

CTRL+F10 is the keyboard shortcut commonly used in Windows to maximize or restore a selected window to its previous size.

In spreadsheet applications, a cell range from A3 through G3 is correctly represented using a colon, specifically keyed in as A3:G3.

Shift + Delete is the shortcut key combination used to permanently delete files or data, bypassing the Recycle Bin or Trash.

The first page of a website that users typically see when they navigate to a web address is universally termed the Homepage.

Mail Merge is the specific function used to personalize letters by adding unique names and addresses for different recipients efficiently.

An embedded organization chart object can be edited by right-clicking it and selecting "Edit Object" or by simply double-clicking the object.

Alt+Ctrl+S is the correct shortcut key in MS Word used to either split a window or remove an existing split view.
