1. What is the main function of the CPU in a computer?

   1. To store data
   2. To process instructions
   3. To display images
   4. To manage user input
   Show answer

   Answer: B. To process instructions

   The CPU (Central Processing Unit) is responsible for processing instructions and carrying out operations in a computer.

2. What fundamental role does the motherboard play in a computer system?

   1. Processes graphics
   2. Connects all computer components
   3. Stores data
   4. Runs software applications
   Show answer

   Answer: B. Connects all computer components

3. How does an SSD differ from an HDD in terms of data storage?

   1. SSDs use moving parts
   2. SSDs use flash memory
   3. HDDs do not store data
   4. HDDs are typically faster
   Show answer

   Answer: B. SSDs use flash memory

   SSDs (Solid State Drives) store data using flash memory, which has no moving parts, unlike HDDs (Hard Disk Drives) which use spinning disks.

4. Why is the northbridge crucial on motherboards, especially in older PCs?

   1. It connects low-speed components
   2. It integrates the CPU with high-speed components
   3. It powers the peripheral devices
   4. It manages the input/output ports
   Show answer

   Answer: B. It integrates the CPU with high-speed components

   Northbridge connects the CPU to high-speed components like RAM and graphics controllers, playing a crucial role in performance management.

5. What is the significance of L1 and L2 cache in a CPU?

   1. They store long-term data
   2. They are used for direct I/O operations
   3. They speed up data access
   4. They manage power usage
   Show answer

   Answer: C. They speed up data access

   L1 and L2 caches are small, faster memory units that store frequently accessed data to reduce access time and improve CPU efficiency.
