Show answer & explanation
Correct answer: C
Statement 1
English:
“Unit of transfer = number of bytes read/written at a time” → ❌ False
In main memory, data is transferred in words (word size), not arbitrary bytes.
Example: If word size = 32 bits → transfer = 4 bytes at once
Statement 2
English:
“Unit of transfer need not equal word or addressable unit” → ✅ True
Transfer unit can differ depending on architecture.
Example: Cache/memory may transfer blocks, not just single words.
