List and describe with details at least three approaches to selecting processes from priority-based multi-level queues.

garik1379 [7]

Based on the information given, it is important to give higher priority to the queue that contains the high priority thread.

<h3></h3><h3>What is the Important Fact?</h3>

A lot of interrupts can take place at any time, and due to that, they cannot always be ignored as the part of code affected by interrupts need to be guarded from constant use.
So, the load-balancing requirements for keeping about the same number of threads would need to be taken or retained and the important case of top priority thread would also be kept.
An priority-based scheduling algorithm can handle this situation if one run queue had all high-priority threads and a second queue had all low-priority threads because if giving greater priority to the two queue that has the national priority comment section as well as, so, first method is the thread in all of the queue.
Multi-level queue scheduling algorithm is used in scenarios where the processes can be classified into groups based on property like process type, CPU time, IO access, memory size, etc. One general classification of the processes is foreground processes and background processes.

An argument is different from a parameter in that an argument

erastovalidia [21]

Answer:

C. is the data passed into a parameter.

Explanation:

From the list of given options, the answer that correctly answers the question is option C.

Literally, arguments are values passed into parameters in functions;

Take for instance, the following code snippet in python

<em>def testcode(num):</em>

<em> print(num * 2)</em>

<em>digit = 4</em>

<em>testcode(digit)</em>

In this example above;

The output is 8; and this is calculated by 4 * 2.

The parameter is <em>num</em><em> </em>and the argument is the <em>value</em> that will <em>be passed in num</em>; This value (argument) is 4

Sketch f(x) = 5x2 - 20 labelling any intercepts.

Norma-Jean [14]

Answer:

The graph of the function is attached below.

The x-intercepts will be: (2, 0), (-2, 0)

The y-intercept will be: (-20, 0)

Explanation:

Given the function

$f\left(x\right)\:=\:5x^2-\:20$

As we know that the x-intercept(s) can be obtained by setting the value y=0

$y=\:5x^2-\:20$

switching sides

$5x^2-20=0$

Add 20 to both sides

$5x^2-20+20=0+20$

$5x^2=20$

Dividing both sides by 5

$\frac{5x^2}{5}=\frac{20}{5}$

$x^2=4$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$x=\sqrt{4},\:x=-\sqrt{4}$

$x=2,\:x=-2$

so the x-intercepts will be: (2, 0), (-2, 0)

we also know that the y-intercept(s) can obtained by setting the value x=0

$y=\:5(0)^2-\:20$

$y=0-20$

$y=-20$

so the y-intercept will be: (-20, 0)

From the attached figure, all the intercepts are labeled.

If a filesystem has a block size of 4096 bytes, this means that a file comprised of only one byte will still use 4096 bytes of s

jenyasd209 [6]

Answer:

Python code given below

Explanation:

def calculate_storage(filesize):

block_size = 4096

full_blocks = filesize // block_size

partial_block = filesize % block_size

if partial_block > 0:

return (full_blocks + 1) * block_size

return filesize

print(calculate_storage(1))

print(calculate_storage(4096))

print(calculate_storage(4097))

Worksheet-I • Make a list of 10 application software and 5 utility programs installed in your computer, along with their uses. U

Andru [333]

Answer:

An antivirus is a utility software that helps to keep the computer virus-free. Moreover, it notifies when any malicious file is detected and removes such files. In addition, it scans any new device attached to the computer and discards any virus if there. Moreover, it also scans the system from time to time for any threats and disposes of them. Examples of antivirus are McAfee Antivirus, Quick heal Antivirus, Windows Defender, etc.

These utility software are used to manage files of the computer system. Since files are an important part of the system as all the data is stored in the files. Therefore, this utility software help to browse, search, arrange, find information, and quickly preview the files of the system.

An important part of a computer is storage space, it is very important to maintain this storage. Therefore, we use certain utility software to compress big files and decrease their size, these are compression tools. The format of the files changes while compressing and we cannot access or edit them directly. In addition, we can easily decompress the file and get the original file back. Examples of compression tools are WinZip, WinRAR, 7-Zip, etc.

These utility software are used to manage data on disks. Moreover, they perform functions like partitioning devices, manage drives, etc. Examples of disk management tools are Mini Tool Partition Wizard, Paragon Partition Manager, etc.

This utility software helps to free up the disk space. In addition, the files which are no longer in use are removed from the disk. Examples are Cortex, C Cleaner, etc.
