In a general-purpose computer system, the CPU, the main memory and the cache may be interconnected via one or more shared system bus(es). However, input/output devices (eg. Hard disk, network interfaces) may only be connected to the system bus through an I/O controller. The following are four statements regarding the requirement for an I/O controller.
1. The capacities of I/O devices are magnitude order larger than that of main memory and hence direct interfacing is impossible.
2. The response times of I/O devices are magnitude order slower than that of CPU and hence direct interfacing is impossible.
3. It is always better to offload the I/O processing to a secondary processor on the I/O controller board than to depend on the primary CPU for I/O processing.
4. The variety of I/O devices in the market requires that a separate I/O controller exists for each device.
What statement(s) best explain the requirement for an I/O controller?
