- D.
A device that collects dust and viruses.
Correct Answer
C. An electronic device that manipulates information and data.Explanation
This definition best describes a computer because it highlights the main function of a computer, which is to manipulate information and data. Computers are electronic devices that can process, store, and retrieve data, and they are widely used for various purposes such as calculations, communication, and data analysis. The other options mentioned in the question, such as a solar calculating machine or a machine used to surf the web, are not comprehensive enough to encompass the full capabilities and functionalities of a computer.Rate this question:

Which of the following is true about the function of the Central Processing Unit (CPU) in a computer?
- A.
The CPU is responsible for storing data and files.
- B.
The CPU executes instructions from software applications, performing calculations and managing data flow.
- C.
The CPU is primarily used for displaying graphics and images on the screen.
- D.
The CPU handles the physical connection of peripherals like keyboards and printers.
Correct Answer
B. The CPU executes instructions from software applications, performing calculations and managing data flow.Explanation
The Central Processing Unit (CPU) is often referred to as the "brain" of the computer because it executes instructions from software, performs calculations, and manages the flow of data between the computer's memory, storage, and other components. While it plays a critical role in overall computer operation, it does not store data or handle the display of graphics directly (tasks performed by storage devices and the GPU, respectively).Rate this question:

The First Computer, created in 1946, was called...
- A.
The Retro-boot
- B.
The atomic calculator
- C.
The web-bot
- D.
The ENIAC
Correct Answer
D. The ENIACExplanation
The correct answer is "The ENIAC." The ENIAC, which stands for Electronic Numerical Integrator and Computer, was the first general-purpose electronic computer. It was created in 1946 and was a significant milestone in the development of computing technology. The ENIAC was a massive machine that used vacuum tubes to perform calculations and was primarily used for scientific and military purposes. It paved the way for future advancements in computer technology and set the foundation for the modern computers we use today.Rate this question:

In todays society, there are many forms of technology that function similarly to a computer. Which is NOT an example of another type of computer system?
- A.
XBOX
- B.
IPOD
- C.
CELL PHONE
- D.
RADIO
Correct Answer
D. RADIOExplanation
The XBOX, iPod, and cell phone are all examples of technology that function similarly to a computer. They have processors, memory, and can perform various tasks like browsing the internet, playing games, and running applications. However, a radio does not have the same capabilities as a computer. It is a device used for receiving and transmitting radio waves, and does not have the ability to process information or perform complex tasks like a computer system.Rate this question:

Choose the part below that is known as the "brain" of the computer.
- A.
CPU
- B.
RAM
- C.
Motherboard
- D.
Monitor
Correct Answer
A. CPUExplanation
The CPU, or Central Processing Unit, is often referred to as the "brain" of the computer because it is responsible for executing instructions and performing calculations. It is the main component that carries out the majority of the computer's processing tasks. The CPU interprets and executes instructions from the computer's memory, performs arithmetic and logical operations, and coordinates the activities of all the other hardware components. Without the CPU, a computer would not be able to function as it is responsible for all the essential operations required for computing.Rate this question:
