Explain the difference between RAM and ROM.

• RAM is volatile and used for temporary storage; ROM is non-volatile and used for permanent storage.

• RAM is used for permanent storage; ROM is volatile and used for temporary storage.

• RAM and ROM are both non-volatile memory types used for the same purpose.

• RAM is slower than ROM and used for long-term data retention; ROM is faster and used for temporary tasks.

What is the purpose of a motherboard in a computer?

• The purpose of a motherboard in a computer is to connect and allow communication between all hardware components.

• To store data permanently in the computer.

• To manage the software applications directly.

• To provide power to the CPU only.

How does a solid-state drive (SSD) differ from a hard disk drive (HDD)?

• SSDs are faster, more durable, and use flash memory, while HDDs are slower, use spinning disks, and are more prone to failure.

• SSDs are less expensive and have larger storage capacities than HDDs.

• HDDs are more durable and use flash memory.

• SSDs use spinning disks and are slower than HDDs.

What is the role of a graphics processing unit (GPU)?

• To store and manage system memory efficiently.

• To enhance audio processing capabilities.

• To control the main CPU and manage system tasks.

• The role of a GPU is to accelerate graphics rendering and perform parallel processing tasks.

Define the term 'IoT' and give an example.

• Internet of Things (IoT); example: smart thermostat.

• Interconnected Objects; example: manual thermostat.

• Internet of Things (IoT); example: traditional thermostat.

• Internet of Technology; example: smart fridge.

What are the advantages of using LED over traditional light bulbs?

• More fragile and prone to breakage

• Advantages of using LED over traditional light bulbs include energy efficiency, longer lifespan, lower heat production, durability, better light quality, and ease of dimming.

• Higher cost compared to traditional bulbs

• Limited color options available

What is the function of a power supply unit (PSU) in a computer?

• The function of a power supply unit (PSU) in a computer is to convert and supply electrical power to the computer's components.

• To store data for the computer's operating system.
