What's this?

• Motherboard

• Hard drive

• Random Access Memory (RAM)

• Fan

Answer explanation

The motherboard is the main circuit board in a computer, connecting all components like the CPU, RAM, and storage. It serves as the backbone of the system, unlike the other options which are individual components.

What does this do?

• Backbone of the computer. All other components are installed into it.

• Stores data

• Projects Wi-Fi signals

• Supplies power to all other components.

Answer explanation

The correct choice describes the motherboard, which is the backbone of a computer. It connects all components, allowing them to communicate and function together, making it essential for the system's operation.

What's this?

• Power supply

• Hard drive

• Random Access Memory (RAM)

• Central Processing Unit (CPU)

Answer explanation

The power supply is responsible for providing electrical power to the computer's components. Unlike the hard drive, RAM, or CPU, which perform specific functions, the power supply is essential for the overall operation of the system.

What's this do?

• Supplies power to all components in the computer

• Stores data

• Makes the computer faster

• Keeps all computer components clean

Answer explanation

The correct answer is 'Supplies power to all components in computer' because the power supply unit (PSU) is responsible for providing electrical power to the computer's hardware, enabling all components to function.

What's this?

• Hard drive

• Soft drive

• Central Processing Unit (CPU)

• Mouse

Answer explanation

The correct answer is 'Hard drive' because it is a storage device used to store data permanently, unlike the other options which serve different functions in a computer system.

What's this do?

• Stores all computer files and data

• Makes the computer faster

• Supplies power to other computer components

• Turns the computer on and off

Answer explanation

The correct answer is 'Stores all computer files and data' because this describes the primary function of a computer's storage system, which retains all files and data necessary for operation.

What's this?

• Central Processing Unit (CPU)

• Hard drive

• Motherboard

• CD/DVD drive

Answer explanation

The Central Processing Unit (CPU) is the primary component of a computer that performs most of the processing inside. It executes instructions from programs, making it essential for the computer's operation.

What's this do?

• Brains of the computer. Processes everything going on in the motherboard.

• Stores all computer files and data.

• Cools down the computer.

• Broadcasts Wi-Fi signals.

Answer explanation

The correct choice describes the CPU, which is the brain of the computer. It processes all instructions and manages operations on the motherboard, unlike the other options that refer to storage, cooling, or networking functions.

What's this?

• Random Access Memory (RAM)

• Hard drive

• Motherboard

• CD/DVD drive

Answer explanation

Random Access Memory (RAM) is a type of computer memory that is used for temporary storage while a computer is running. It allows for quick access to data, making it essential for system performance.

What's this do?

• Short-term memory that helps the computer multitask and process information faster.

• Stores all computer files and data.

• Cools down the computer.

• Supplies power to computer components.

Answer explanation

The correct choice describes short-term memory, known as RAM, which allows a computer to multitask and process information quickly. The other options refer to storage, cooling, and power supply, which are different functions.
