Which of the following storage technologies support random (direct) access to arbitrary memory locations?
Which of the following storage technologies support random (direct) access to arbitrary memory locations?
Multiple Choice Options
- A
Magnetic disk storage
- B
Semiconductor RAM
- C✓ Correct Option
Both Magnetic Disk and Semiconductor RAM
- D
Magnetic tape only
Detailed Technical Solution & Explanation
Both Magnetic Disks (HDDs) and Semiconductor RAM support direct access (random access) where the system can navigate directly to any desired track/sector or memory address without reading through all preceding linear records sequentially (unlike sequential magnetic tape).
Option Analysis:
•
Option A (Disk): Supports direct block addressing via cylinder/head/sector.
•
Option B (RAM): Supports direct random byte addressing.
•
Option C (Both Disk and RAM): Correct; both support direct access mechanisms.
•
Option D (Magnetic tape): Strictly sequential access medium.
