Answer:
B. blocking I/O
Explanation:
Most of the input and output request placed to the computer considers the blocking request. It means that the controls given cannot be returned to the given application until and unless the input/output is complete.
Thus, blocking the input/output does not return till the input and output is complete.
With a blocking I/O, the process is moved to a wait queue when the I/O request is made, and it moved backs to the ready queue as soon as the request is complete, thereby allowing the other processes to run in the meantime.
Thus (B) blocking I/O is the answer.

The answer is the last option
Answer:
Answer explained below
Explanation:
Following are the arguments that can be used to persuade our colleagues in Des Moines to switch there network to IPv6 or to enable dual use of IPv6 and IPv4 :
- IPv6 provides an increased capacity of address space as resources are efficiently allocated to provide coverage to additional web addresses.
- IPv6 provides efficient routing by conveniently aggregating the prefixes that have been assigned to IP networks.
- IPv6 conserves bandwidth by enabling large data packets. it uses less bandwidth than IPv4 for the same data.
- IPv6 is more secure than IPv4 due to multiple security layers built in the firewall. It also provides authentication layers and integrity of data.
- IPv6 supports multicast rather than broadcast.
- IPv6 has more efficient packet processing and error detection through checksum as compared to IPv4.
- Address and network configuration is fully simplified and automatic in IPv6 but the same is not true for IPv4.
- IPv4 supports 32 bit IP address whereas IPv6 supports 128 bit. Therefore more number of IP addresses availability makes IPv6 future oriented.
This is an incomplete question. The complete question is given below:
Mike has never used slide presentation software before but he needs to create a presentation by the end of the week what resource would be most helpful to mike
a. The 350-page printed manual from the slide presentation software publisher
b. A free tutorial the slide presentation software publisher has posted on the company website
c. A trouble-shooting website created by a third party
d. The 350-page online manual from the slide presentation software publisher
Answer:
b - A free tutorial the slide presentation software publisher has posted on the company website
Explanation:
As Mike has a short time and no prior experience with a slide software, then in this scenario, the best, simplest and fastest way to learn and create a presentation a free tutorial which the slide presentation software publisher has posted on the company website as this is the same company that has created this particular software so he can be rest-assured that the resource he is relying on is authentic and up-to-date with information on latest features.
Moreover, it's efficient and quick way to learn from a free tutorial rather than from 350-page printed or online manual especially for a beginner.
Besides, his purpose is to create the presentation using the software and not trouble-shooting so trouble-shooting website created by a third party is not useful for him and it also might not be authentic or updated as well.
Machine language.
Hope this helps
