-
Software
-
RAM
-
Input Devices
-
Hardware
Correct Answer
A. SoftwareExplanation
Software refers to the collection of instructions, data, or programs used to operate computers and execute specific tasks. It is a vital component of a computer system, distinct from the physical hardware, and serves as the guiding framework that tells the hardware how to perform tasks. Software includes everything from the operating system (which manages the computer's core functionality and user interface) to application programs (like word processors, web browsers, and games) that perform specific user-directed tasks. The term encapsulates various types of software, including system software, application software, and utility software, each serving different functions but collectively enabling a computer to operate effectively and efficiently.Rate this question:

What is the name of the computer's short-term memory that is lost when the computer is turned off?
-
CPU
-
Hardware
-
RAM
-
Processor
Correct Answer
A. RAMExplanation
RAM stands for Random Access Memory, which is the computer's short-term memory that is lost when the computer is turned off. It is a volatile memory that stores data that is actively being used by the computer's operating system and applications. When the computer is powered off, the data stored in RAM is erased, which is why it is considered as short-term memory. CPU, hardware, and processor are not the correct answers as they refer to different components and functionalities of a computer.Rate this question:

What are the parts of a computer called that allow the user to see or hear information produced by the computer?
-
Software
-
Input Device
-
Output Device
-
Operating System
Correct Answer
A. Output DeviceExplanation
Output devices are components of a computer system that convert the information processed by the computer into a form perceptible to users. Common examples include monitors, which display visual information, and speakers, which produce audio. These devices are essential for conveying the results of computer processes to users, enabling them to interact with and utilize the data. Unlike input devices that send data to the computer for processing, output devices receive data from the computer after it has been processed, making it accessible and understandable to human users. This function is vital for completing the communication loop in human-computer interaction.Rate this question:

What is the primary function of the BIOS in a computer system?
-
It acts as an interface between the hardware and operating system.
-
It controls external peripherals like printers and USB devices.
-
It provides internet access to the system.
-
It enhances the graphics performance of a computer.
Correct Answer
A. It acts as an interface between the hardware and operating system.Explanation
The BIOS (Basic Input/Output System) is essential firmware stored on a chip in the motherboard. It initializes hardware during the boot process and provides a communication bridge between the system's hardware and operating system. Without BIOS, the computer cannot start or recognize connected devices. Additionally, the BIOS also manages the power-on self-test (POST) and allows users to configure system settings such as boot order and date/time. Overall, the BIOS plays a crucial role in ensuring the proper functioning of a computer system. It is a fundamental component that facilitates the interaction between hardware and software, ultimately enabling the system to operate efficiently.Rate this question:

What is the computer part called that stores programs and information on two or more disks within the computer?
-
Motherboard
-
Hard Drive
-
CPU
-
Operating System
Correct Answer
A. Hard DriveExplanation
A hard drive, or hard disk drive (HDD), is a data storage device found inside computers that uses one or more rotating disks coated with magnetic material to store and retrieve digital information. It is responsible for permanently storing all forms of data and programs even when the computer is turned off, making it essential for the long-term retention of data. Unlike RAM, which is volatile and loses data upon power loss, a hard drive keeps data until it is erased or overwritten. Hard drives come in various sizes and capacities, accommodating everything from basic documents to large video files, and are fundamental for the overall functionality and memory capacity of a computer system.Rate this question:

What is the name of the computer part that reads information from a disk?
-
Operating System
-
Motherboard
-
Hard Drive
-
Disk Drive
Correct Answer
A. Disk DriveExplanation
A disk drive is a device within a computer that reads data from physical disk media, such as hard disks, floppy disks, or optical disks (CDs, DVDs). This component is essential for accessing, retrieving, and processing the information stored on these disks. Disk drives can be built into the computer (as with hard drives) or can be external devices (like external DVD drives or portable hard drives). They play a crucial role in the functionality of a computer by enabling the user to load software, access files, and perform data backups. The disk drive’s ability to read and sometimes write information to a disk makes it indispensable for everyday computing tasks and long-term data storage.Rate this question:

What is the name of the program that controls a computer's basic functions?
-
Hard Drive
-
Motherboard
-
Operating System
-
CPU
Correct Answer
A. Operating SystemExplanation
An operating system (OS) is the software that manages the computer hardware and software resources and provides common services for computer programs. It acts as the foundation on which application programs can be run. The OS performs basic tasks such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system has even greater responsibilities and powers, ensuring that different programs and users running at the same time do not interfere with each other. The operating system is thus a crucial component that allows the user to interact with the computer without needing to understand the language of binary code.Rate this question:

-
Operating system
-
Motherboard
-
Computer
-
CPU
Correct Answer
A. ComputerExplanation
A computer is an electronic tool that allows information to be input, processed, and output. It consists of various components such as the motherboard, CPU, and operating system, which work together to perform these functions. The motherboard is the main circuit board that connects all the components, while the CPU is the central processing unit responsible for executing instructions. The operating system is the software that manages the computer's resources and provides a user interface. However, the computer as a whole encompasses all these components and functions.Rate this question:

In computing, what does the term ‘booting’ refer to?
-
Installing a new software application.
-
Restarting a computer to refresh its performance.
-
The process of starting a computer and loading the operating system.
-
Removing viruses from the system.
Correct Answer
A. The process of starting a computer and loading the operating system.Explanation
Booting is the sequence of events that occur when a computer is powered on. The system runs the BIOS/UEFI, checks hardware components, and loads the operating system into RAM. This process allows the user to interact with the computer. Booting can be ‘cold’ (powering on) or ‘warm’ (restarting). Cold booting involves a full system initialization, while warm booting skips certain checks and processes. Both methods are essential for the proper functioning of a computer and ensure that the operating system is loaded correctly for user interaction.Rate this question:
