COMPUTER SYSTEMS AND ARCHITECTURE REVISION
UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
Question:
1. FDE Cycle
Answer:
Stands for Fetch, Decode, and Execute; the core operational cycle performed by the CPU.
Question:
2. Program Counter (PC)
Answer:
Holds the memory address of the next instruction to be fetched from primary memory.
Question:
3. Memory Address Register (MAR)
Answer:
Holds the memory address of the current instruction to be fetched or transferred.
Question:
4. Memory Data Register (MDR)
Answer:
Holds the contents found at the MAR address, or data to be transferred.
Question:
5. Accumulator (ACC)
Answer:
Holds the results of calculations performed by the ALU.
Question:
6. Clock Speed
Answer:
Measured in Hertz; sends pulses in fixed intervals to determine FDE cycles per second.
Question:
7. Cache Memory
Answer:
Fast CPU memory storing frequently used instructions to reduce RAM retrieval wait times.
Question:
8. Control Unit (CU)
Answer:
Sends control signals around the CPU to coordinate and control hardware.
, Question:
9. ALU (Arithmetic Logic Unit)
Answer:
CPU component that performs mathematical calculations and logic checks.
Question:
10. Embedded System
Answer:
A computer system built inside a larger device to perform a specific dedicated task.
Question:
11. Open Source Software
Answer:
Software with publicly available source code that users can freely view, edit, and share.
Question:
12. Proprietary Software
Answer:
Copyrighted software with hidden source code requiring a paid license to use.
Question:
13. ROM (Read-Only Memory)
Answer:
Non-volatile primary storage that permanently stores the BIOS and boot-up sequence.
Question:
14. RAM (Random Access Memory)
Answer:
Volatile primary storage that temporarily holds data and programs currently in use.
Question:
15. Secondary Storage
Answer:
Non-volatile, long-term storage used for data and programs when not immediately needed.
Question:
16. Magnetic Storage
Answer:
High capacity and low cost storage with moving parts, such as hard disk drives (HDDs).
Question:
17. Solid State Storage
Answer:
Very fast, durable, and portable storage with no moving parts, such as SSDs.
