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

In a batch operating system, three jobs JOBI, JOB2, JOB3 are submitted for ex- ecution. Each job involves an I/O activity, a CPU time, and another 1/0 activity. JOB1 requires a total of 21 ms, with 3 ms CPC time. JOB2 requires 29 ms total time with 5 ms CPU time. 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
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]

Answer:
A reverse proxy.
Explanation:
A service that might appear to be a single server to external clients, but actually represents many servers living behind it, is known as a reverse proxy.
In Computer Networking, a single server can be configured to appear as the endpoint for many other servers acting behind it through the use of a reverse proxy.
Hence, a reverse proxy is a type of server that is placed right in front of other servers such as a web server and forwards or routes the user's (client) requests to those servers sitting behind it. When properly configured, reverse proxy helps to ensure security, reliability and performance of a network.

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.
Therefore, Through a link or communication channel, nodes are connected. A computer network may use cable, fiber, or both of these.

The IT manager has tasked you with installing new physical machines. These computer systems are barebone systems that simply establish a remote connection to the data center to run the user's virtualized desktop. Which type of deployment model is being used
The type of deployment model that is used is referred to as Thin client.
A thin client is also referred to as lean client. It is a model that runs on the resources that are stored on a central server rather than in the resources if the computer.
A thin client is useful for shared services, and desktop virtualization. The work carried out by the server include storage of data, performing if calculation, launching software programs etc.
On conclusion, since the information given in the question explains that there's a remote connection to the data center to run the user's virtualized desktop, then the deployment model is a thin client.

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.
