What is the primary function of the Central Processing Unit (CPU) in a computer?

• To store data permanently

• To perform arithmetic and logical operations

• To display graphics on the screen

• To provide power to the computer

Answer explanation

The primary function of the CPU is to perform arithmetic and logical operations, which are essential for executing instructions and processing data in a computer. Other options do not accurately describe the CPU's main role.

Which component of a computer is responsible for connecting the CPU to other components?

• Hard-disk drive

• Solid-state drive

• Motherboard

• Power supply

Answer explanation

The motherboard is the main circuit board that connects the CPU to other components like RAM, storage, and peripherals, allowing communication between them. Other options do not serve this purpose.

What is the main advantage of a solid-state drive (SSD) over a hard-disk drive (HDD)?

• Lower cost per gigabyte

• Faster data access speed

• Larger storage capacity

• More durable in physical shocks

Answer explanation

The main advantage of an SSD over an HDD is its faster data access speed. SSDs use flash memory, allowing for quicker read and write times compared to the mechanical parts of HDDs, resulting in improved overall performance.

Which of the following is considered secondary storage in a computer?

• RAM

• CPU

• SSD

• Graphics card

Answer explanation

An SSD (Solid State Drive) is a type of secondary storage used to store data persistently, unlike RAM, which is volatile memory. The CPU and graphics card are not storage devices, making SSD the correct choice.

What does the motherboard primarily consist of?

• A series of fans and cooling systems

• A printed circuit board with spaces for components

• A collection of software applications

• A set of external ports and connectors

Answer explanation

The motherboard is primarily a printed circuit board that provides the foundation for connecting various components, such as the CPU, RAM, and expansion cards, making it essential for a computer's functionality.

Which of the following is NOT a function of the CPU?

• Controlling the flow of data between the CPU and memory

• Handling communication with peripherals

• Storing data permanently

• Performing logical operations

Answer explanation

The CPU does not store data permanently; that function is handled by storage devices like hard drives or SSDs. The CPU controls data flow, communicates with peripherals, and performs logical operations.

What is the main disadvantage of hard-disk drives (HDDs) compared to solid-state drives (SSDs)?

• Higher cost

• Slower data access speed

• Less storage capacity

• More complex installation process

Answer explanation

The main disadvantage of HDDs compared to SSDs is their slower data access speed. HDDs use spinning disks, which makes them significantly slower in reading and writing data compared to the flash memory used in SSDs.

Which component is directly responsible for executing instructions in a computer?

• Motherboard

• CPU

• RAM

• SSD

Answer explanation

The CPU (Central Processing Unit) is the primary component responsible for executing instructions in a computer. It processes data and performs calculations, making it essential for running programs.

What type of memory is used for long-term data storage in a computer?

• RAM

• Cache

• Secondary storage

• Virtual memory

Answer explanation

Secondary storage is used for long-term data storage in a computer, unlike RAM and cache, which are temporary. Virtual memory is a technique that uses disk space to extend RAM but is not a primary storage type.

Which of the following is a characteristic of a motherboard?

• It is a type of secondary storage

• It is a software application

• It allows components to communicate with each other

• It performs arithmetic operations

Answer explanation

The correct choice is that the motherboard allows components to communicate with each other. It serves as the main circuit board, connecting the CPU, memory, and other hardware, enabling data transfer and coordination among them.
