Which of the following is not a common input device?

Keyboard
Mouse
Printer

Correct Answer

A. Printer

Explanation

A printer is not considered a common input device because it is primarily used for outputting information onto paper or other media. Input devices are used to input data or commands into a computer system, whereas a printer is used to produce physical copies of digital information. The keyboard and mouse, on the other hand, are common input devices as they allow users to input data and commands into the computer.

The physical components of the computer are known as:

Hardware
Software
CPU

Correct Answer

A. Hardware

Explanation

Hardware refers to the physical components of a computer system, including the central processing unit (CPU), memory, storage devices, input/output devices, and other peripheral devices. Unlike software, which consists of programs and data that can be stored and executed on the hardware, hardware refers to the tangible parts of the computer that can be seen and touched. Therefore, hardware is the correct answer to the question.

What is multitasking?

When more than one user is accessing a network at the same time
When a computer is running multiple applications at one time
When a computer application is performing multiple tasks automatically

Correct Answer

A. When a computer is running multiple applications at one time

Explanation

Multitasking refers to the ability of a computer to run multiple applications simultaneously. This means that the computer can handle multiple tasks or processes at the same time, allowing users to switch between different applications without any noticeable delay. Multitasking enhances productivity and efficiency by allowing users to perform multiple tasks concurrently, such as browsing the internet while listening to music or working on a document while running a virus scan in the background.

Commercially-produced software written by programmers to perform a specific task.

Operating System
Windows
Applications Software

Correct Answer

A. Applications Software

Explanation

Applications software refers to commercially-produced software that is designed to perform specific tasks. Unlike an operating system, which manages the computer's hardware and provides a platform for other software to run on, applications software is focused on providing functionality to users. This can include a wide range of software, such as word processors, spreadsheets, graphic design programs, and video editing software. Applications software is typically created by programmers to meet the needs of specific tasks or industries, and it is often sold or licensed to users for their personal or professional use.

The "brain" of the computer, through which information to and from all applications and harware runs

Hard Drive
Finder
CPU

Correct Answer

A. CPU

Explanation

The CPU, or Central Processing Unit, is often referred to as the "brain" of the computer because it is responsible for executing instructions and performing calculations. It acts as the control unit, coordinating and managing the flow of data between all applications and hardware components. The CPU processes and interprets instructions from the computer's memory, performs arithmetic and logical operations, and controls the timing and execution of instructions. It is a crucial component that plays a vital role in the overall functioning and performance of the computer system.
