Answer: applications software

Explanation:

When installing applications software, the user typically needs to copy and decompress program files from a CD-ROM or other medium to the hard disk. This is done so that the program can be run from the hard disk, rather than requiring the CD-ROM or other installation media to be inserted each time the program is used. The installation process may also involve setting up shortcuts and creating registry entries on the user's system.

Answer: microprocessor

Explanation:

The CPU, also called the microprocessor when talking about PCs, does the vast majority of the processing for a computer. The CPU is the brain of the computer and is responsible for executing instructions, performing calculations, and managing data flow between different components of the computer system. The CPU is typically located on the motherboard and communicates with other components through a system bus. It is often referred to as the "heart" of the computer because it performs all of the essential functions that allow the computer to operate.

Answer: speed

Explanation:

A computer's type, processor, and operating system define its platform. The platform refers to the underlying hardware and software architecture of a computer system, which determines how software programs are run and how devices interact with the system. The platform includes the type of computer (desktop, laptop, tablet, etc.), the processor (Intel, AMD, ARM, etc.), and the operating system (Windows, macOS, Linux, etc.). Different platforms may have different capabilities, performance characteristics, and software compatibility, which can affect the user experience and the types of applications that can be run on the system.

Answer: Sound Card

Explanation:

Sound Card. To hear music on a computer, a sound card is required. The sound card is a component of the computer that processes audio signals, converting them into digital signals that can be played through the computer's speakers or headphones. Without a sound card, a computer would not be able to produce any sound. While a video card is responsible for processing visual images and a mouse and joystick are input devices used to control a computer, they are not required to hear music on a computer. A tape recorder is also not needed to hear music on a computer.

Answer: Disk

Explanation:

Disk. A disk is a secondary memory device because it is a non-volatile storage device that can be used to store data and programs over a long period of time, even when the power is turned off. Keyboard, ALU (Arithmetic Logic Unit), mouse, and printer are not secondary memory devices. Keyboard and mouse are input devices used to enter data into a computer, ALU is a processing unit, and printer is an output device used to produce hard copies of digital documents.

Answer: Power-On-Self-Test

Explanation:

Power-On-Self-Test (POST). When a computer is switched on, the booting process performs a Power-On-Self-Test (POST), which is a diagnostic test that checks the hardware components of the computer to ensure that they are functioning properly. Integrity Test, Correct Functioning Test, and Reliability Test are not specific tests that are performed during the booting process. Shut-down is the process of turning off the computer.

Answer: any device that is attached to a computer system

Explanation:

any device that is attached to a computer system. The general term "peripheral equipment" is used for any device that is attached to a computer system, but is not part of the core computer architecture, which includes the CPU, memory, motherboard, and other essential components. Examples of peripheral equipment include printers, scanners, external hard drives, mice, keyboards, and monitors. These devices are connected to the computer through ports, such as USB, HDMI, or Ethernet, and are used to expand the functionality of the computer system.

Answer: Slots

Explanation:

The hardware components that provide expansion capability for a computer system are (b) slots. Slots are connectors on the motherboard that allow for the addition of expansion cards or peripheral devices to the computer system. Expansion cards can include things like graphics cards, sound cards, network cards, and other components that enhance the functionality of the computer system. Sockets are connections on the motherboard for installing processors or memory modules, bytes are units of digital information, and bays are the spaces in a computer case where storage drives can be installed.

Answer: An MP3 file

Explanation:

The item that is not a hardware component is (a) An MP3 file. It is a type of digital audio file that can be stored on a hardware device such as a computer or a smartphone.

Answer: Buses

Explanation:

The sets of parallel electrical conducting lines that link different components on the motherboard of a PC unit are called buses. Therefore, option (b) is the correct answer.
