Think about what computers can and can't do. Can they understand a poem?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Computers cannot understand a poem because understanding requires human-like cognitive abilities such as emotions, subjective experiences, and contextual knowledge. While computers can analyze the structure, patterns, and language of a poem, they lack the capacity to interpret its deeper meaning, appreciate its aesthetic qualities, or empathize with the emotions conveyed. Therefore, the statement that computers can understand a poem is false.Rate this question:

Which of these devices are input devices?
- A.
Screen
- B.
Mouse
- C.
Barcode reader
- D.
Printer
Correct Answer(s)
B. Mouse
C. Barcode readerExplanation
The mouse and barcode reader are both input devices because they allow the user to input data into the computer system. The mouse allows the user to move the cursor on the screen and click on various objects, while the barcode reader scans barcodes and inputs the corresponding information into the computer. The screen and printer, on the other hand, are output devices as they display or produce information from the computer system.Rate this question:

A computer can sense the outside world. Which of these can be detected by sensors?
- A.
The level of light
- B.
The volume of noise
- C.
The anger of people
- D.
The temperature of the room
Correct Answer(s)
A. The level of light
B. The volume of noise
D. The temperature of the roomExplanation
Sensors are devices that can detect and measure physical properties or phenomena. The level of light can be detected by light sensors or photodiodes, which convert light energy into electrical signals. The volume of noise can be detected by microphones or sound sensors, which convert sound waves into electrical signals. The temperature of the room can be detected by temperature sensors, such as thermocouples or thermistors, which measure changes in temperature and convert them into electrical signals. However, sensors cannot directly detect or measure emotions like anger, as emotions are subjective experiences that cannot be quantified by physical properties.Rate this question:

Computers are made up of hardware and software running on the hardware. Which of these are considered to be hardware?
- A.
The CPU
- B.
The fetch-execute process
- C.
The power supply unit
- D.
Windows
Correct Answer(s)
A. The CPU
C. The power supply unitExplanation
The CPU and the power supply unit are considered to be hardware components of a computer. The CPU (Central Processing Unit) is the main component responsible for executing instructions and performing calculations. The power supply unit is responsible for providing electrical power to the computer components. On the other hand, the fetch-execute process and Windows are software components that run on the hardware.Rate this question:

All computers have an operating system. This runs to enable them to carry out tasks. Which of these are part of the operating system?
- A.
Memory allocation
- B.
Dealing with inputs
- C.
Searching the web
- D.
Displaying windows
Correct Answer(s)
A. Memory allocation
B. Dealing with inputs
D. Displaying windowsExplanation
The operating system is responsible for managing various aspects of a computer's functionality. Memory allocation is a crucial part of this, as the operating system determines how and where to allocate memory resources to different programs and processes. Dealing with inputs refers to the operating system's ability to handle user input, such as keyboard and mouse interactions. Displaying windows is another key function of the operating system, as it manages the graphical user interface and allows users to interact with different applications and programs. Searching the web, however, is not typically a part of the operating system's responsibilities.Rate this question:

There are three types of network connection, those connected through a cable, those connected through a wireless system, and those connected via the mobile telephone system. Check the ones where wireless would be the best or only service available for each of these devices.
- A.
A tablet computer
- B.
An office desktop PC
- C.
A mobile phone at home
- D.
A remote printer OR scanner device
Correct Answer(s)
A. A tablet computer
C. A mobile pHone at homeExplanation
For a tablet computer, wireless would be the best or only service available because it allows for mobility and convenience without the need for a physical cable connection. Similarly, for a mobile phone at home, wireless would be the best or only service available as it allows for flexibility and mobility within the home environment.Rate this question:

A is the CPU where the processing takes place?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement "A is the CPU where the processing takes place" is true. The CPU, or Central Processing Unit, is the primary component of a computer where most of the processing occurs. It is responsible for executing instructions, performing calculations, and managing data flow between different parts of the computer system. Therefore, the CPU is indeed where the processing takes place.Rate this question:

B is the CD drive secondary storage?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given answer, False, is correct because a CD drive is not considered secondary storage. Secondary storage refers to devices like hard drives, solid-state drives, and external storage devices that are used to store data for a longer period of time. A CD drive, on the other hand, is considered an optical drive and is primarily used for reading and writing data from CDs or DVDs, making it a type of input/output device rather than secondary storage.Rate this question:

In the fetch-execute cycle, Some instructions require data.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In the fetch-execute cycle, instructions are fetched from memory and executed by the processor. Some instructions, such as arithmetic or logical operations, require data to perform the desired operation. This data is typically fetched from memory or registers and used in the execution phase of the cycle. Therefore, it is true that some instructions in the fetch-execute cycle require data.Rate this question:
-
- 14.
The fetch-execute cycle takes place in the CPU.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The fetch-execute cycle is a fundamental process in a CPU where it fetches instructions from memory, decodes them, executes them, and then stores the results. This cycle is responsible for executing instructions and performing calculations in a computer. Therefore, it is true that the fetch-execute cycle takes place in the CPU.Rate this question:

The fetch-execute cycle is a continuous process while the computer is running.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The fetch-execute cycle is a continuous process that occurs while the computer is running. This cycle involves fetching instructions from memory, decoding them, executing the instructions, and then repeating the cycle. It is an essential process for the computer to carry out tasks and perform computations. Therefore, the statement "The fetch-execute cycle is a continuous process while the computer is running" is true.Rate this question:
-

The execute instruction ends the fetch-execute process
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The execute instruction does not end the fetch-execute process. In fact, it is a crucial part of the process. After the fetch instruction retrieves the next instruction from memory, the execute instruction carries out the operation specified by that instruction. It is followed by the fetch instruction again to retrieve the next instruction, and the process continues until the program is complete. Therefore, the statement that the execute instruction ends the fetch-execute process is false.Rate this question:
