The I/O methods in which memory addresses and I/O addresses are distinct is called:
A. Isolated I/O
B. Memory-Mapped I/O
C. Strobe Control
D. Handshaking
E. Interrupt
🎥 Video solution / Text Solution of this question is given below:
Isolated I/O (Port-mapped I/O) → Memory and I/O address spaces are separate.
• Memory-Mapped I/O → I/O devices share the same address space as memory.
The question asks where memory and I/O addresses are distinct, which corresponds to Isolated I/O.
Among the given combinations, the most appropriate option containing this concept is A.
