Answer:
The answer to this question can be defined as follows:
In option 1, the answer is "18.75%".
In option 2, the answer is "33%".
Explanation:
Given:
JOB 1-Time of the CPU = 3ms, rest = 18ms, sum = 21
JOB 2-Time of the CPU = 5ms, rest = 24ms, sum = 29
JOB 3 -Time of the CPU =4ms, rest = 10ms, sum = 14
In option 1:
whenever the job has also been allocating the system, in the uni-programs system, which looks at the CPU until it is complete.
Formula:
[tex]\text{Utilization of CPU} =\frac{ \text{total time of CPU} }{ \text{full real time}}[/tex]
[tex]=\frac{(3+5+4)}{(21+29+14)}[/tex]
[tex]=\frac{12}{64}\\\\= 0.1875\\\\=18.75%[/tex]
In option 2:
However, if any software is interested in other operations like I / o, it can assign to the CPU Processor to others Systems and other software may be carrying out I / o operations there while the processor is with any other application.
Formula:
[tex]\text{Utilization of CPU} =\frac{ \text{total time of CPU} }{ \text{full real time}}[/tex]
[tex]=\frac{12}{36}\\\\=\frac{1}{3}\\\\=.33\\\\= 33 \%[/tex]

IPv6 can use a DHCPv6 server for the allocation of IPv6 addressing to hosts. Another IPv6 addressing option utilizes the IPv6 Neighbor Discovery Protocol (NDP) to discover the first portion of the IPv6 address (network prefix) from local routers, and the host can create its own host ID. What standard is commonly used by an IPv6 host to generate its own 64-bit host ID
Answer:
Following are the answer to this question.
Explanation:
It is a mechanism, that is also known as EUI-64, which enables you an automatic generation of its specific host ID. It using the device on the 48-bit MAC address, which helps to construct the special 64-bit host ID.

Assume that strike Counter has already been declared to be a "pointer to int". Assume further that strike Counter has been initialized -- its value is the address of some int variable. Write a statement that adds 22 to the value of the variable that strikeCounter is pointing to.
Answer:
The statement to this question can be defined as follows:
*strike_Counter =*strike_Counter +22;//adds value 22 in *strike_Counter
Explanation:
In the given question, it is already defined, that "strike_Counter" is an integer pointer variable, which means, it only holds the integer value in its address memory.
In the next step, it is defined, that it adds the value "22" in its variable, and for this, we declare the statement in the answer section, which adds the value.
for example, if in the "strike_Counter" variable holds the integer value, that is 5 and after adding the 22 it will become 27.

Your computer science teacher asks you to sample a black and white image that is 4" x 6". How would you sample the image to provide a good digital approximation using the pixelation widget? What sample size would you use? How would your decision affect the digital representation?
Answer:
The largest dimensions we can make of an image with the pixelation widget is 255*255.
When an image is resized, the number of pixels in the image may be reduced or increased, which causes the image to be resampled. Resampling changes the file size.
Explanation: This is all I could find. I hope its helps Sorry.
The sample size that would provide a good digital approx. will be 255 x 255
When resizing images using the pixelation widget, the pixels of the image will either reduce or increase and the reduction/increase in the pixels will have an effect ( blurry effect ) on the image when viewed by the user. also
when an image is resized the size of original size is either larger or smaller than the resampled image.
Hence to provide a good digital approx. using the pixelation widget from an image 4" x 6" is by using a sample size of 255 x 255
Note : A picture showing the effect of pixelation is attached below

3. POP.
4. IMAP.
5. POP.
6. POP.
7. 110.
8. IMAP-capable server.
Explanation:
The application layer process that sends mail uses Simple Mail Transfer Protocol (SMTP). When a client sends email, the client process connects with a server process on well-known port 25. A client retrieves email, however, using one of two application layer protocols: Post Office Protocol (POP) or Internet Message Access Protocol (IMAP). With POP, mail is downloaded from the server to the client and then deleted on the server. The server starts the POP service by passively listening on TCP port 110 for client connection requests. However, when a client connects to a server running IMAP, copies of the messages are downloaded to the client applications. The original messages are kept on the server until they are manually deleted.
