Answer:
1. Processor communication -- this involves the following tasks:
<em>a. exchange of data between processor and I/O module</em>
<em>b. command decoding - I/O module accepts commands sent from the processor. E.g., the I/O module for a disk drive may accept the following commands from the processor: READ SECTOR, WRITE SECTOR, SEEK track, etc. </em>
<em>c. status reporting – The device must be able to report its status to the processor, e.g., disk drive busy, ready etc. Status reporting may also involve reporting various errors. </em>
<em>d. Address recognition – Each I/O device has a unique address and the I/O module must recognize this address. </em>

2. Device communication – The I/O module must be able to perform device communication such as status reporting.
3. Control & timing – The I/O module must be able to co-ordinate the flow of data between the internal resources (such as processor, memory) and external devices.
4. Data buffering – This is necessary as there is a speed mismatch between speed of data transfer between processor and memory and external devices. Data coming from the main memory are sent to an I/O module in a rapid burst. The data is buffered in the I/O module and then sent to the peripheral device at its rate.
5. Error detection – The I/O module must also be able to detect errors and report them to the processor. These errors may be mechanical errors (such as paper jam in a printer), or changes in the bit pattern of transmitted data. A common way of detecting such errors is by using parity bits.
Answer:
Her performance over the course of a season.
Explanation:
An athlete is signed for a season. These days each aspect of an athlete is noted through the effective use of the best technology. However, for detailed study, one or several plays, and certainly not the second half of a game is enough. It's required to collect the details for a complete season. And that is possible, as an athlete is hired for a season. And through such a detailed data set of a complete season, we can now train a machine as well, and it will let the athlete know where she is going wrong. And thus she can improve and remove those faults from her game, and become a better athlete. And even for a coach, one complete season is required, though when he has not seen her playing before that season. It's assumed that this is her first season. All the options mentioned are good, but the best is certainly the one with complete details, and that is a complete season. The rest is good but not the best.
