SINF6 Computer Studies Practice Questions - Solomon Islands National Form Six Examination - Computer Studies Exam - SINF6 Computer Studies Practice Questions - Solomon Islands National Form Six Examination

Question 1

Which internal component of the Central Processing Unit (CPU) is directly responsible for decoding instruction opcodes and generating the timing and control signals needed to coordinate data transfer across the system?

Control Unit (CU) Arithmetic Logic Unit (ALU) Memory Address Register (MAR) Program Counter (PC)

Correct Answer:

Control Unit (CU)

Question 2

How does Random Access Memory (RAM) differ fundamentally from Read-Only Memory (ROM) in a personal computer?

RAM is volatile and allows read/write operations during execution, whereas ROM is non-volatile and permanently stores firmware instructions like BIOS. RAM retains its content when power is disconnected, whereas ROM loses all stored data instantly. RAM is used exclusively for long-term storage of user files, whereas ROM functions as temporary cache memory. RAM operates at significantly slower speeds than ROM because it relies on mechanical magnetic platters.

Correct Answer:

RAM is volatile and allows read/write operations during execution, whereas ROM is non-volatile and permanently stores firmware instructions like BIOS.

Question 3

Cache memory is organized into levels (L1, L2, and L3). Which statement correctly describes the performance and capacity trade-offs across these cache levels?

L1 cache has the fastest access time and smallest capacity, while L3 cache has larger capacity but higher latency. L1 cache has the largest storage capacity and slowest clock speed, while L3 cache is integrated directly into processor registers. L3 cache is located off the motherboard on optical drives, while L1 cache stores non-volatile startup firmware. L1, L2, and L3 caches have identical capacities and speeds, differing only in their power consumption.

Correct Answer:

L1 cache has the fastest access time and smallest capacity, while L3 cache has larger capacity but higher latency.

Question 4

A system bus consists of three distinct functional signal lines: Data Bus, Address Bus, and Control Bus. What is the specific function of the Address Bus?

It carries memory address signals unidirectionally from the CPU to identify specific physical RAM locations. It transfers bidirectional binary data words between the CPU, RAM, and storage controllers. It transmits timing pulses and read/write signal commands from external peripheral devices to CPU registers. It converts parallel optical signals into serial electrical streams for monitor displays.

Correct Answer:

It carries memory address signals unidirectionally from the CPU to identify specific physical RAM locations.

Question 5

What is the 'Von Neumann Bottleneck' in computer architecture?

The throughput limitation caused by sharing a single physical bus between the CPU and memory for both instruction fetches and data transfers. The delay caused by magnetic hard drive platters spinning up to full operational speed during boot. The inability of 32-bit operating systems to run 64-bit application binaries natively. The thermal throttling triggered when a graphics processing unit exceeds safe operating temperatures.

Correct Answer:

The throughput limitation caused by sharing a single physical bus between the CPU and memory for both instruction fetches and data transfers.
