Peripherals

1. Which of the following is NOT a computer peripheral?

Central processing unit

Keyboard

Printer

Microphone

Scanner

The central processing unit (CPU) is not a computer peripheral because it is the main component of a computer that carries out instructions and performs calculations. It is the "brain" of the computer and is responsible for executing tasks and processing data. In contrast, peripherals are devices that connect to the computer and provide additional functionality, such as input (keyboard, microphone, scanner) or output (printer). The CPU is an integral part of the computer system and is not considered a peripheral.

2. You can remove all peripherals from a computer and it will continue to function properly.

True

False

The statement is true because peripherals such as monitors, printers, keyboards, and mice are not essential for the basic functioning of a computer. The computer can still operate and perform tasks without these peripherals. However, it may not be able to perform certain specific functions that require the use of peripherals.

3. What are the three general types of peripheral devices?

Internal, wired external and wireless external

Audio, video and print output

Input, output and storage

Mouse, keyboard and monitor

The three general types of peripheral devices are input, output, and storage. Input devices are used to input data or commands into a computer, such as a keyboard or mouse. Output devices display or present information from a computer, such as a monitor or printer. Storage devices are used to store and retrieve data, such as hard drives or USB flash drives. These three types cover the main functions of peripheral devices in a computer system.

4. External wireless peripherals can be connected to a computer in the following ways:

A Bluetooth connection

A cable using a USB or other connection

A WiFi connection

None of the answers are correct

All answers are correct

The correct answer is all answers are correct. This is because external wireless peripherals can indeed be connected to a computer through a Bluetooth connection, a cable using a USB or other connection, or a WiFi connection. All of these methods are valid ways to connect wireless peripherals to a computer.

5. Technically speaking, what is the most accurate description of a peripheral device?

A device connected to a computer using a cable

A device that plugs into a computer using a USB connection

A device that provides input and output functions for a computer system

A device that is connected to a computer but is not part of the core computer architecture

A peripheral device is a device that is connected to a computer but is not part of the core computer architecture. This means that it is an external device that can be attached to a computer system to provide additional functionality or perform specific tasks. Peripheral devices can include input devices such as keyboards and mice, output devices such as monitors and printers, as well as storage devices, network devices, and other accessories. These devices are connected to the computer through various means such as cables, USB connections, or wireless connections.
