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?
Answers
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

1. Here is a program segment to find the quantity base . Both base and exp are entered at the keyboard. System.out.println("Enter base and exponent: "); double base = IO.readDouble();// read user input double exp = IO.readDouble(); // read user input /* code to find power, which equals baseexp */ System.out.print(base + " raised to the power " + exp); System.out.println(" equals " + power); Which code is a correct replacement for /* code to find power, which equals baseexp */ ?
Answers
Answer:
The correct code to this question can be de4fined as follows:
double power;
power = Math.pow(base, exp);
Explanation:
In the given question the choices were missing, that's why we defined the correct code only.
In the given code a two double variable "base and exp" is declared, that input the value from the user-side, and store its value into there respective variables. In the next step, "power", that is a double variable is declared, which uses the "Math.pow" function that calculates given values power and prints its value.please find the attachment of the full code.

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
Answers
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.

Complete Question:
You administer your company's 100BaseTX Ethernet network. TCP/IP is the networking protocol used on the network. You want the routers on the network to send you notices when they have exceeded specified performance thresholds. Which protocol should you use to enable the routers to send the notices?
Group of answer choices
A. ARP
B. SMTP
C. SNMP
D. Telnet
Answer:
C. SNMP.
Explanation:
In this scenario, you administer your company's 100BaseTX Ethernet network. TCP/IP is the networking protocol used on the network. Also, you want the routers on the network to send you notices when they have exceeded specified performance thresholds. Hence, you should use the SNMP to enable the routers to send the notices.
SNMP is an acronym for simple network management protocol, which is a standardized application-layer protocol that is used for monitoring and organizing management information about network devices on either a wide area network (WAN) or local area network (LAN).
Basically, the SNMP helps to provide a common language for network devices such as switches, routers, printers, servers etc to share information with a network management system.
A simple network management protocol (SNMP) is part of the Transmission Control Protocol and Internet Protocol (TCP⁄IP) suite.

JOB3 requires 14 ms total time with 4 is CPU time. 3.1 What will be the CPU utilisation for uniprogramming? Write down all interme diate steps. 3.2 What will be the CPU utilisation for multiprogramming? Write down all inter- mediate steps
Answers
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]

How do a router and switch differ when handling a message? Both a router and a switch use the message’s destination address to select the line to route the incoming message to. The switch will purposefully drop messages if message traffic exceeds its capacity. The router will purposefully drop messages if message traffic exceeds its capacity. There is no difference in how a router and a switch handle messages.
Answers
Answer:
The router will purposefully drop messages if message traffic exceeds its capacity.
Explanation:
As we know that the router and the switch are the connecting devices. The router works at the network layer and used for determining the shortest path
On the other hand the switch work is to connected many devices that are available in the network.
Therefore the correct option is second as the router also depicts when there is the purpose of the messaged drop[ed if the traffic of message exceeds than its capacity

Note that a group of two or more interconnected nodes makes up a node network. Once a connection has been established between two or more nodes, all searches return lists of configured users and resources from both nearby and distant nodes. Every computer in the node network keeps track of this fundamental data.
