What is the function of I/O interface? Differentiate between Isolated I/O and memory mapped I/O. [5]
An I/O Interface acts as a bridge between the CPU/memory system and the peripheral (I/O) devices. Its main functions are: 1. Data Buffering - Temporarily holds data to compensate for the speed difference between the fast CPU and slow I/O devices. 2. Signal Conversion - Converts signals between th...
