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]
The quicksort is an example of a divide and conquer algorithm in that it divides the sorting problem into smaller problems by dividing the list of items to be sorted into smaller subsets. The pivot is the mechanism that is used to segment the list. Describe how the quicksort works including a discussion of the pivot, how it is selected, and why the pivot is important to the quicksort.
Answer:
The quicksort pivot is an arbitrary element within the collection that is being sorted. Using the pivot point, the collection of elements is partitioned into two smaller lists of elements. Using some logic, the smaller elements are placed left of the pivot point, and larger elements are placed to the right of the pivot point. Ideally, you would prefer you pivot point to be a median of your dataset to optimize the creation of the two sublists into a balanced state.
Cheers.
The pivot of a quicksort algorithm ought to always be the element in the middle. Some algorithms will choose the item in the center as the pivot, while others will choose the first or last element.
What is quicksort algorithm?Quicksort is a sorting method that operates in-place. It was created by British computer scientist Tony Hoare and is still a widely used sorting algorithm.
When properly implemented, it can be slightly faster than merge sort and two or three times faster than heapsort.
The quicksort pivot can be any element in the collection being sorted. The collection of elements is divided into two smaller lists of elements using the pivot point.
Smaller elements are placed to the left of the pivot point, while larger elements are placed to the right of the pivot point.
To optimize the creation of the two sub-lists into a balanced state, you would prefer your pivot point to be the median of your dataset.
Thus, this way quicksort works.

Mark is the network administrator in his building and is responsible for training all the new technicians on various troubleshooting techniques. He is instructing them on documenting their actions at the end of the troubleshooting process. What should he NOT encourage them to document at that time
Answer:
See answer below
Explanation:
He should not encourage his new technicians to document theories that were followed at the end of the troubleshooting process. This because the theory might not add to their knowledge about troubleshooting. What is paramount and needed to be documented for future references are their findings, actions taken by them and the outcome achieved through the whole troubleshooting process.
In trouble shooting, a technician aims at solving problems on computer system by following a set of steps such as establishing theory of probable cause, testing the theory to determine the cause, establishing a plan of action and implementing the solutions; in order to determine and solve the problem.
The theories here are the steps that were followed in determining and solving the observed issues hence should not be documented except the findings, actions taken and the final outcomes that were achieved.

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? The film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. There were only a few people who could afford the technology to produce color motion pictures back then. Color films had to be hand-colored, frame by frame. Audiences did not want color motion pictures until later.
Answer:
Color films had to be hand-colored, frame by frame.
Explanation:
Colored films were a rarity during the late 18th and early 19th centuries. Most movies were produced in black and white as the production of colored films was a difficult task as the films have to be hand-colored, frame by frame.
However, things began to change with the development of art and technology. While the dye is used to tint the color of certain scenes before, the new development in the films allows the capture of all scenes in color. But this does not mean that all films are shot in color. Most films continued to be shot in black and white even after the development of colored films.

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.

Question 55 :You use a computer named Wkst1 on a TCP/IP network, which is installed with an application that uses UDP to send a file from your computer to a computer named Wkst2. Data collisions occur, and several data packets are lost during transmission. What will most likely occur as a result of losing the packets during transmission?
Answer:
The protocol will drop the packets
The application will automatically re-transmit the packets
Explanation:
Based on design, the routers will drop the packets as allowed by the Internet Protocol, due to the collision that resulted from the router being busy and the network is congested or that the packet is corrupt as indicated by the check sequence of the Ethernet frame or the IPv4 header checksum
Given that the application uses User Datagram Protocol (UDP) which does not allow recovery of lost packets, but have their defined methods of overseeing lost packets, as such the application will re-transmit the packet.

With a C program (memory map), data in _____ is initialized by the kernel to arithmetic 0 or null pointers before the program starts executing. The C declaration (for example, "long sum[1000];") appearing outside any function causes this variable to be stored in _____.
Answer:
The answer is " Uninitialized data segment ".
Explanation:
It (memory map) field whenever a C program is locked to run, the kernels must allocate information into 0 or null pointer in this section until the process runs. This variable, that is outside of any function, has been stored in uninitialized data item by the C statement (like, "long amount[1000];").
If we did not declare the data segment, it also called bss, in which all block which begins with the symbol and is called for an old assembly language operator.
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. It also helps you to build a DHCP-type IPv6 network, that's why we can say that the above-given standard is widely used to create a 64-bit host ID on IPv6 servers.
