BGCSE Computer Studies 0597 Practice Questions - Botswana General Certificate of Secondary Education - Computer Studies (Syllabus 0597) Exam - BGCSE Computer Studies 0597 Practice Questions - Botswana General Certificate of Secondary Education

Question 1

Which component of the von Neumann CPU architecture is responsible for performing arithmetic operations (such as addition and subtraction) and logical evaluations?

Arithmetic Logic Unit (ALU) Control Unit (CU) Program Counter (PC) Memory Data Register (MDR)

Correct Answer:

Arithmetic Logic Unit (ALU)

Question 2

During the CPU fetch-decode-execute cycle, what is the primary role of the Program Counter (PC)?

To store the result of the most recent ALU computation To hold the memory address of the next instruction to be executed To store the current instruction while it is being decoded To hold the data value fetched directly from secondary storage

Correct Answer:

To hold the memory address of the next instruction to be executed

Question 3

Why is cache memory positioned between the CPU cores and main RAM in modern computer architecture?

Cache memory provides larger storage capacity than secondary magnetic storage at lower cost Cache memory is non-volatile, protecting critical OS files during sudden power losses Cache memory provides extremely fast access times for frequently used instructions, reducing CPU idle time Cache memory converts analog input signals into digital signals for processing

Correct Answer:

Cache memory provides extremely fast access times for frequently used instructions, reducing CPU idle time

Question 4

Which statement accurately describes a fundamental difference between RAM and ROM?

RAM is read-only memory, whereas ROM can be written to and modified continuously RAM is non-volatile primary memory, whereas ROM loses its data when the computer is turned off RAM holds temporary data and running software, whereas ROM contains permanent startup code (BIOS/UEFI) RAM is secondary magnetic storage, whereas ROM is primary optical storage

Correct Answer:

RAM holds temporary data and running software, whereas ROM contains permanent startup code (BIOS/UEFI)

Question 5

What technology allows Electrically Erasable Programmable Read-Only Memory (EEPROM) to be updated without physically removing the chip from the circuit board?

Exposure to high-intensity ultraviolet (UV) light bulbs through a glass window Application of electric voltage signals to erase and rewrite data blocks electronically Magnetic realignment of iron oxide particles on the surface of the chip Manual mechanical switching of micro-diodes using physical pin tools

Correct Answer:

Application of electric voltage signals to erase and rewrite data blocks electronically
