Computers have become everyday use machinery where most people know how to operate them. The main functions of a computer are to input, store, process and output. Take this basic quiz on computer functions and see just how much you know about how it is capable of performing said functions. All the best!

• 1.

### Input refers to when a computer takes in information.

• A.

True

• B.

False

A. True
Explanation
The statement is true because input in the context of a computer refers to the process of the computer receiving or taking in information. This can be done through various input devices such as keyboards, mice, or touchscreens, where the computer collects data or commands from the user. Input is an essential part of the computer's operation as it allows users to interact with the system and provide the necessary instructions or data for processing.

### A computer takes in information through ____________________ devices.

input
Explanation
A computer takes in information through input devices. These devices allow the computer to receive data and instructions from the user or other external sources. Input devices include keyboards, mice, scanners, microphones, and touchscreens, among others. They convert physical inputs into digital signals that the computer can process and use for various tasks. Without input devices, the computer would not be able to interact with users or gather information from the outside world.

### Processing refers to when a computer sends out information

• A.

True

• B.

False

B. False
Explanation
Processing refers to the manipulation and transformation of data by a computer. It involves performing calculations, executing instructions, and managing data storage. Sending out information is just one part of the processing task, but it does not fully define what processing is. Therefore, the given statement is false.

### The abbrivation for central processing unit is:

• A.

MOG

• B.

CTP

• C.

CPU

• D.

CPA

C. CPU
Explanation
The correct answer is CPU, which stands for Central Processing Unit. The CPU is the primary component of a computer that carries out instructions and performs calculations, making it the "brain" of the computer. It processes data and coordinates the activities of all the other hardware components, including memory, storage, and input/output devices. The abbreviation CPU is widely used and recognized in the field of computing.

### ________ is the part of the computer that does most of the job of using information

CPU
Central Processing Unit
Explanation
The CPU, also known as the Central Processing Unit, is the part of the computer that performs the majority of tasks related to processing and using information. It is responsible for executing instructions, performing calculations, and managing the flow of data within the computer system. The CPU acts as the brain of the computer, coordinating and controlling the operations of other hardware components and software programs.

### The third basic computer function is ________? This refers to when a computer sends out information.

• A.

Output

• B.

Input

• C.

Processing

• D.

Devices

A. Output
Explanation
The third basic computer function is output. This refers to when a computer sends out information. Output is the process of displaying or presenting data or information in a usable format, such as through a monitor, printer, or speakers. It involves the computer transmitting or presenting the results of its processing to the user or another device.

Rate this question:

• 7.

### A computer sends out information through ________________ devices.

output
Explanation
A computer sends out information through output devices. Output devices are hardware components that display or transmit data from a computer to the user or other devices. Examples of output devices include monitors, printers, speakers, and projectors. These devices allow the computer to communicate and share information with the user or other external devices.

Rate this question:

• 8.

### Hardware is the physical equiptment of a computer. It includes:

• A.

Input Devices

• B.

Memory and CPU

• C.

Output Devices

• D.

All of the Above

D. All of the Above
Explanation
The correct answer is "All of the Above" because hardware refers to the physical components of a computer system. This includes input devices such as keyboards and mice, memory and CPU (central processing unit), and output devices such as monitors and printers. Therefore, all the options listed in the question are part of the hardware of a computer.

Rate this question:

• 9.

### Storage refers to when information is saved in a computer.

• A.

True

• B.

False

A. True
Explanation
The statement accurately defines what storage means in the context of computers. Storage refers to the process of saving information in a computer, whether it be in the form of files, documents, or other data. This can be done using various types of storage devices such as hard drives, solid-state drives, or cloud storage services. Therefore, the given statement is true.

Rate this question:

• 10.

### _______________ is the instructions that tell a computer what to do.

software
Explanation
Software refers to the set of instructions or programs that are designed to perform specific tasks on a computer. These instructions provide the necessary guidance to the computer on how to execute different operations and tasks. Software can be categorized into different types such as operating systems, applications, and utilities, each serving a specific purpose in instructing the computer on what actions to take. Therefore, software is the correct answer as it accurately describes the instructions that guide a computer's actions.

Rate this question:

• 11.

### A computer saves information in:

• A.

RAM

• B.

Long-Term Memory

• C.

All Of the Above

• D.

None of the Items Above

C. All Of the Above
Explanation
A computer saves information in both RAM (Random Access Memory) and long-term memory. RAM is a type of volatile memory that is used for temporary storage of data while the computer is running. Long-term memory refers to permanent storage devices such as hard drives, solid-state drives, and optical discs, where data is stored even when the computer is turned off. Therefore, the correct answer is "All Of the Above" as both RAM and long-term memory are used for saving information in a computer.

Rate this question:

• 12.

### Another type of storage is read only memory, or ROM.

• A.

True

• B.

False

A. True
Explanation
Read only memory, or ROM, is a type of storage that permanently stores data and instructions that cannot be modified or erased. It is non-volatile, meaning that the data remains intact even when the power is turned off. Unlike random access memory (RAM), which is volatile and can be written and rewritten, ROM is used for storing firmware, boot loaders, and other essential system software. Therefore, the statement "Another type of storage is read only memory, or ROM" is true.
