Technology Basics Re-Test Test

Which of the following is an example of input hardware?

• Monitor

• Keyboard

• Printer

• Speaker

Answer explanation

The keyboard is an example of input hardware as it allows users to input data into a computer. In contrast, a monitor, printer, and speaker are output devices that display or produce information.

What is the primary function of an operating system?

• To perform calculations

• To manage computer hardware and software resources

• To create documents

• To design graphics

Answer explanation

The primary function of an operating system is to manage computer hardware and software resources, ensuring efficient operation and coordination between applications and hardware.

Identify the component that is considered the "brain" of the computer.

• Hard Drive

• RAM

• CPU

• GPU

Answer explanation

The CPU, or Central Processing Unit, is often referred to as the "brain" of the computer because it performs the majority of processing tasks, executing instructions and managing operations, unlike the Hard Drive, RAM, or GPU.

Which of the following is a function of system software?

• Word processing

• Managing files on the computer

• Editing photos

• Browsing the internet

Answer explanation

System software manages hardware and system resources. Among the options, managing files on the computer is a core function of system software, while word processing, photo editing, and browsing are functions of application software.

Differentiate between system software and application software with an example.

• System software is used for browsing the internet, while application software is used for managing hardware.

• System software includes operating systems like Windows, while application software includes programs like Microsoft Word.

• System software is used for creating documents, while application software is used for managing files.

• System software is used for editing photos, while application software is used for calculations.

Answer explanation

The correct choice highlights that system software, like operating systems (e.g., Windows), manages hardware resources, while application software, such as Microsoft Word, is designed for specific tasks like document creation.

Explain how a printer functions as an output device.

• It receives data from the computer and prints it on paper.

• It inputs data into the computer for processing.

• It stores data for future use.

• It processes data and sends it to the CPU.

Answer explanation

A printer functions as an output device by receiving data from the computer and converting it into a physical format, typically by printing it on paper. This makes the first answer choice correct.

Which of the following is NOT a basic component of a computer?

• Monitor

• Mouse

• Operating System

• Scanner

Answer explanation

A scanner is not a basic component of a computer. Basic components typically include the monitor, mouse, and operating system, which are essential for operation and user interaction.

Describe the role of RAM in a computer system.

• It permanently stores data and files.

• It processes graphics and images.

• It temporarily stores data for quick access by the CPU.

• It manages network connections.

Answer explanation

RAM (Random Access Memory) temporarily stores data for quick access by the CPU, allowing for faster processing and multitasking. This is crucial for the performance of applications and overall system efficiency.

What is the difference between input and output devices?

• Input devices send data to the computer, while output devices receive data from the computer.

• Input devices receive data from the computer, while output devices send data to the computer.

• Input devices store data, while output devices process data.

• Input devices process data, while output devices store data.

Answer explanation

Input devices, like keyboards and mice, send data to the computer, allowing user interaction. Output devices, such as monitors and printers, receive data from the computer to display or produce results. Thus, the correct choice is the first one.

Which of the following is an example of application software?

• Linux

• Microsoft Excel

• BIOS

• Android

Answer explanation

Microsoft Excel is application software used for creating spreadsheets, while Linux and Android are operating systems, and BIOS is firmware. Therefore, Excel is the correct example of application software.
