Which of the following is true about the function of the Central Processing Unit (CPU) in a computer?

The CPU is responsible for storing data and files.
The CPU executes instructions from software applications, performing calculations and managing data flow.
The CPU is primarily used for displaying graphics and images on the screen.
The CPU handles the physical connection of peripherals like keyboards and printers.

Correct Answer

A. 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).

The First Computer, created in 1946, was called...

The Retro-boot
The atomic calculator
The web-bot
The ENIAC

Correct Answer

A. The ENIAC

Explanation

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.

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?

XBOX
IPOD
CELL PHONE
RADIO

Correct Answer

A. RADIO

Explanation

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.

Choose the input device from the list below.

Speaker
Mouse
Printer
Monitor

Correct Answer

A. Mouse

Explanation

The mouse is the correct answer because it is an input device. Input devices are used to input data or commands into a computer system, and the mouse allows the user to move the cursor and interact with the computer by clicking on icons, buttons, and menus. The other options listed (speaker, printer, and monitor) are output devices, which are used to display or output information from the computer.

Choose the output device from the list below.

Keyboard
Scanner
Mouse
Printer

Correct Answer

A. Printer

Explanation

The printer is the correct answer because it is an output device that produces a physical copy of documents or images. The keyboard, scanner, and mouse are all input devices used to provide information to the computer.

Choose the part below that is known as the "brain" of the computer.

CPU
RAM
Motherboard
Monitor

Correct Answer

A. CPU

Explanation

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.

Which of the following is known as the main circuit board, located inside the tower?

Power cord
Motherboard
Keyboard
Surfboard

Correct Answer

A. Motherboard

Explanation

The main circuit board, known as the motherboard, is located inside the tower. It is responsible for connecting and allowing communication between various hardware components such as the processor, memory, and storage devices. The motherboard also provides power to these components and facilitates data transfer. The power cord is responsible for supplying power to the entire system, while the keyboard is an input device used for typing. The surfboard is not related to computer hardware and is an incorrect option.
