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.

Explanation:
Interntors present an interesting kind of people who think in peculiar ways sometimes. This ability allows them to view certain situations in ways in which other people cannot. Because of this, they can think of new ways of how such situations can be tackled. This is how inventions are born. A person with an inventive mind sees a new situation where he thinks of a new solution how he could improve this situation with his invention.
This process is continued continuously with new generations of inventors seeing and coming back to old situations over and over again, inventing new things along the way.
Answer:
C. can boost server utilization rates to 70% or higher.
Explanation:
Virtualization -
It is the process of running virtual instance of the computer in the abstracted layer from the very actual hardware , is known as virtualization .
In this process multiple operating system can be operated on the single computer setup , it is useful for increasing the speed of the program.
Hence, from the question,
The correct statement with respect to virtualization is C. can boost server utilization rates to 70% or higher .
False because if you edit the ownership of file it will give permissions only with the permissions you can edit file,rename,or delete file.
