1.
Which of the following is an operating system you would be using on a computer?
Correct Answer
B. Microsoft Windows XP
Explanation
An operating system (OS) is an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of the computer that acts as a host for computing applications run on the machine. Microsoft Windows XP is an example of an operating system used on personal computers.
2.
What does RAM stand for?
Correct Answer
D. Random Access Memory
Explanation
Random Access Memory (usually known by its acronym, RAM) is a form of computer data storage. It allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory. It is a type of volatile memory that stores data temporarily while the computer is on.
3.
Physical components that make up your computer are known as
Correct Answer
B. Hardware
Explanation
Hardware encompasses all physical components integral to a computer's operation or connected to it. These components include the fundamental building blocks like the motherboard, CPU, RAM, and hard disk, which form the core infrastructure. Additionally, hardware extends to peripherals such as input devices like keyboards and mice, output devices like monitors and printers, and expansion cards like graphics cards, network adapters, and sound cards. This comprehensive range of physical elements collectively enables a computer system to function effectively.
4.
What is 3?
Correct Answer
A. CPU
Explanation
The Central Processing Unit (CPU) performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer. It executes instructions, performs calculations, and manages data movement within the computer system.
5.
What is 2?
Correct Answer
B. Motherboard
Explanation
The motherboard is the main component inside the case. It is a large rectangular board with integrated circuitry that connects the rest of the parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots.
6.
Which of the following is required to hear music on your computer?
Correct Answer
D. Sound Card
Explanation
A sound card (also known as an audio card) is a computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. It is essential for producing sound output from a computer, including music, speech, and other audio signals.
7.
What is Virtual Memory?
Correct Answer
A. As primary memory fills the system moves the least-used chunks to secondary storage devices, retrieving when they are needed.
Explanation
Virtual memory is a memory management capability of an operating system (OS) that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to disk storage. As primary memory fills up, the system moves the least-used chunks to secondary storage devices, retrieving them when they are needed again.
8.
Which of the following is not an input device?
Correct Answer
B. Optical Plotter
Explanation
An input device is any peripheral used to provide data and control signals to a computer. Optical plotters, unlike traditional input devices, are primarily output devices employed to produce high-resolution graphical outputs on paper or other media based on digital data input. They are commonly used in engineering and design for large-format printing and drawing.
9.
Which of the following is not an output device?
Correct Answer
A. Web Cam
Explanation
An output device is any peripheral device that communicates information or data from a computer system to the user or to other devices. Common output devices include laser printers, speakers, inkjet printers, and monitors. However, a webcam is primarily used for inputting video and audio data into a computer system, making it an input device rather than an output device. It captures video and audio signals for transmission over networks or recording for playback, rather than presenting information to the user.
10.
Which one of these is not an Application Program?
Correct Answer
E. Turbo Pascal
Explanation
Application software, commonly known as applications or apps, is computer software designed to perform specific tasks or functions for end-users. Turbo Pascal, however, is an integrated development environment (IDE) and a programming language primarily used for software development, particularly in the realm of procedural and object-oriented programming.
11.
What is a Peripheral?
Correct Answer
D. A device that is connected to a computer
Explanation
A peripheral device is any external hardware device connected to a computer that expands its capabilities or serves as an interface for interaction. These devices include input peripherals like keyboards, mice, scanners, and joysticks, as well as output peripherals like monitors, printers, speakers, and projectors. Peripherals enhance the functionality and usability of a computer system.
12.
What does BIOS stand for?
Correct Answer
D. Basic Input Output System
Explanation
The BIOS, or Basic Input Output System, is a fundamental firmware embedded in the motherboard of a computer. It provides essential low-level functionality to initialize and control hardware components during the boot process. The BIOS also facilitates communication between the operating system and hardware, manages system configuration settings, and performs power-on self-tests (POST) to ensure hardware integrity.
13.
Which of the following is not found on the Motherboard?
Correct Answer
B. Power Supply
Explanation
The motherboard, also referred to as the mainboard or logic board, is a crucial circuit board in modern computers that houses essential components and facilitates their communication. While the power supply unit (PSU) is a critical component of a computer system, providing electrical power to the motherboard and other hardware components, it is typically located external to the motherboard within the computer case.
14.
Which of the following is not one of the four main steps of a CPU?
Correct Answer
D. Organise
Explanation
The central processing unit (CPU) of a computer executes instructions through a series of steps known as the fetch-decode-execute cycle, also called the instruction cycle. These steps include fetching the instruction from memory, decoding it into a set of commands, executing the commands, and storing the result if necessary. "Organize" is not a distinct step in this process but rather an overarching concept encompassing the CPU's coordination and control of operations.
15.
Which of the following is not connected to Computer Storage?
Correct Answer
C. DVD Flash Drive
Explanation
DVD flash drives are not a common form of computer storage medium. However, CD-ROMs, USB flash drives, DVD discs, Blu-ray writers (BD-Writers), and hard disks are widely used for storing and retrieving digital data. These storage devices vary in capacity, speed, and durability, catering to diverse storage needs ranging from data backup and file transfer to multimedia content distribution and archival storage.
