Lesson 1.2 Quiz

Which of the following BEST represents the order of the computing cycle?

• Input, process, storage, and output

• Output, input, process, and storage

• Process, storage, input, and output

• Process, input, output, and storage

Answer explanation

The computing cycle consists of four main stages: first, data is inputted, then processed, stored if necessary, and finally outputted. Thus, the correct order is Input, process, storage, and output.

Tom is writing a report on his computer about the solar system. He describes each planet, inserts images, and saves his document. Later, he opens the file to make some edits before printing it out. In this scenario, which step of the computing cycle makes it possible for Tom to be able to reopen and edit his report?

• Input

• Output

• Process

• Storage

Answer explanation

The step of the computing cycle that allows Tom to reopen and edit his report is 'Storage'. This is where the document is saved, enabling him to access it later for modifications.

Which of the following is considered an input device?

• Monitor

• Speaker

• Keyboard

• Printer

Answer explanation

A keyboard is an input device used to enter data into a computer. In contrast, a monitor and printer are output devices, while a speaker outputs sound. Therefore, the correct answer is the keyboard.

What hardware component processes data?

• Hard drive

• Central Processing Unit

• Input device

• System memory

Answer explanation

The Central Processing Unit (CPU) is the primary hardware component responsible for processing data. It executes instructions and performs calculations, making it essential for the operation of a computer.

Which of the following is a short-term storage device?

• Compact disc

• Flash drive

• Hard disk

• RAM

Answer explanation

RAM (Random Access Memory) is a short-term storage device used for temporary data storage while a computer is running, making it the correct choice. Other options like hard disks and flash drives are long-term storage devices.

Which of the following are optical storage devices? (Select two.)

• Blu-ray disc

• DVD

• HDD

• SSD

• USB flash drive

Answer explanation

Blu-ray discs and DVDs are optical storage devices that use lasers to read and write data. In contrast, HDDs, SSDs, and USB flash drives use magnetic or electronic methods for data storage.

Why is RAM an example of a volatile storage device?

• RAM is not enclosed in a protective case, and is more easily damaged than a hard drive.

• Data stored in RAM is only stored as long as there is a power source sending constant power to the chip.

• RAM chips can easily be removed from the motherboard.

• RAM can easily be upgraded and replaced in most sizes and brands of computer systems.

Answer explanation

RAM is considered volatile because it loses all stored data when the power is turned off. This means data in RAM is only retained while there is a constant power supply, making the correct choice the one that highlights this characteristic.

Which of the following is an output device?

• Touchpad

• Monitor

• Microphone

• Scanner

Answer explanation

A monitor is an output device that displays visual information from a computer. In contrast, a touchpad is an input device, a microphone captures audio input, and a scanner digitizes images, making them input devices.

What term is used to describe devices like printers, screens, and speakers in relation to a computer?

• Peripherals

• Connections

• Components

• Internals

Answer explanation

The term 'Peripherals' refers to external devices like printers, screens, and speakers that connect to a computer, enhancing its functionality. Other options like 'Connections' and 'Internals' do not accurately describe these devices.

What is the primary function of output devices connected to a computer?

• To facilitate user interaction with the computer's operating system

• To display or produce the results of a computer's processes to the user

• To increase the computer's processing power

• To provide the computer with external data to process

Answer explanation

The primary function of output devices is to display or produce the results of a computer's processes to the user, such as showing images on a monitor or printing documents, making this the correct choice.
