Which one of these isn't an input device?
- A.
Mouse
- B.
Keyboard
- C.
Speakers
- D.
Microphone
Correct Answer
C. SpeakersExplanation
Speakers are not considered an input device because they are used to output sound, rather than inputting data or commands into a computer system. Input devices are typically used to provide input or instructions to a computer, such as a mouse or keyboard. While speakers are an important component of a computer system, they are classified as output devices because they produce sound output rather than accepting input.Rate this question:

An operating system is a piece of software that communicates with the hardware and allows other programs to run.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
An operating system is a software that acts as an intermediary between the hardware and other software programs. It manages the computer's resources, such as memory and processor, and provides a platform for programs to run on. By handling tasks like device drivers, memory allocation, and scheduling, the operating system ensures that different programs can run efficiently and interact with the hardware effectively. Therefore, the statement "An operating system is a piece of software that communicates with the hardware and allows other programs to run" is true.Rate this question:

Which of these would a microprocessor be found in?
- A.
Mobile Phone
- B.
Washing Machine
- C.
Calculator
- D.
Microphone
Correct Answer(s)
A. Mobile Phone
B. Washing MachineExplanation
A microprocessor is a small electronic chip that functions as the central processing unit (CPU) of a computer. It is responsible for executing instructions and performing calculations. In the context of the given options, both mobile phones and washing machines can have microprocessors. Mobile phones are essentially mini-computers, while modern washing machines often have advanced features that require a microprocessor to control various functions. On the other hand, calculators typically use simpler integrated circuits rather than microprocessors, and microphones do not require a microprocessor for their basic functionality.Rate this question:

A microprocessor is a component that needs instructions to work.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A microprocessor is a central processing unit (CPU) that is responsible for executing instructions and performing calculations in a computer system. It relies on instructions to carry out its tasks, which are typically provided by the computer's operating system or software programs. Without instructions, a microprocessor would not be able to perform any meaningful operations and would essentially be idle. Therefore, it is true that a microprocessor needs instructions to work.Rate this question:

A cooker needs a ______________ to work?
Correct Answer
MicroprocessorExplanation
A cooker needs a microprocessor to work because a microprocessor is a small computer chip that acts as the brain of the cooker. It controls and manages various functions of the cooker, such as temperature control, timing, and programming. The microprocessor receives input from the user, processes the information, and sends commands to different components of the cooker to perform specific tasks. Without a microprocessor, the cooker would not be able to function properly and perform its intended tasks.Rate this question:

You should never download a untrusted file from the internet because...
- A.
It may contain a virus
- B.
You will get an electric shock
- C.
It may contain explicit/inappropriate files.
- D.
It will make your screen brake
Correct Answer(s)
A. It may contain a virus
C. It may contain explicit/inappropriate files.Explanation
Downloading untrusted files from the internet can be risky because they may contain viruses that can harm your computer or steal your personal information. Additionally, these files may also contain explicit or inappropriate content that could be offensive or illegal. Therefore, it is important to exercise caution and only download files from trusted sources to ensure the safety and security of your device and personal data.Rate this question:

A solid-state drive is an input device.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A solid-state drive (SSD) is not an input device. It is a storage device that uses integrated circuit assemblies to store data persistently. SSDs are commonly used to store and retrieve data in computers and other electronic devices, but they do not directly input data into the device. Input devices are typically devices that allow users to input data or commands into a computer, such as keyboards, mice, or touchscreens. Therefore, the statement that a solid-state drive is an input device is false.Rate this question:

A CPU (Central Processing Unit) is described as what part of the body?
- A.
Liver
- B.
Arm
- C.
Brain
- D.
Intestine
Correct Answer
C. BrainExplanation
A CPU (Central Processing Unit) is the main component of a computer that carries out instructions and performs calculations. It is often referred to as the "brain" of the computer because it controls and coordinates all the activities of the computer system, just like the brain controls and coordinates the activities of the human body. Therefore, the correct answer is "Brain".Rate this question:
