A network technician is planning to update the firmware on a router on the network. The technician has downloaded the file from the vendor's website. Before installing the firmware update, which of the following steps should the technician perform to ensure file integrity?
a. Perform antivirus and anti-malware scans of the file.
b. Perform a hash on the file for comparison with the vendor’s hash.
c. Download the file a second time and compare the version numbers.
d. Compare the hash of the file to the previous firmware update.
Answer: B. Perform a hash on the file for comparison with the vendor’s hash.
Explanation:
Before installing the firmware update, the step that the technician should perform to ensure file integrity is to perform a hash on the file for comparison with the vendor’s hash.
Hashing refers to the algorithm that is used for the calculation of a string value from a file. Hashes are helpful in the identification of a threat on a machine and when a user wants to query the network for the existence of a certain file.
Think Critically 5-1 Creating Flexible Storage.
It's been 6 months since the disk crash at CSM Tech Publishing, and the owner is breathing a little easier because you installed a fault-tolerant solution to prevent loss of time and data if a disk crashes in the future. Business is good, and the current solution is starting to get low on disk space. In addition, the owner has some other needs that might require more disk space, and he wants to keep the data on separate volumes. He wants a flexible solution in which drives and volumes aren't restricted in their configuration. He also wants to be able to add storage space to existing volumes easily without having to reconfigure existing drives. He has the budget to add a storage enclosure system that can contain up to 10 HDDs. Which Windows feature can accommodate these needs, and how does it work?
Answer:
The Storage Spaces feature in Windows
Explanation:
The Storage Spaces feature can be used here. This feature was initiated in Windows server 2012 and allows the user store his files on the cloud or virtual storage. This makes it possible to have a flexible storage as there is a storage pool which is updated with more storage capacity as it decreases. The feature also offers storage security, backing up files to other disks to protect against total loss of data on a failed disk.
(Ramanujan's Taxi) Srinivasa Ramanujan indian mathematician who became famous for his intuition for numbers. When the English mathemematician G.H. Hardy came ot visit him in the hospital one day, Hardy remarked that the number if his taxi was 1729, a rather dull number. To which Ramanujan replied, "No, Hardy! It is a very interesting number. It is the smallest number expressible as the sum of two cubes in two different ways." Verify this claim by writing a program Ramanujan.java that takes a command-line argument N and prints out all integers less than or equal to N that can be expressed as the sum of two cubes in two different ways. In other words, find distinct positive integers a, b, c, and d such that а3 + b3 = c3 - d3. Hint: Use four nested for loops, with these bounds on the loop variables: 0 < a < 3√N, a < b < 3√N - a3, a < c < 3√N and c < d < 3√N - C3; do not explicitly compute cube roots, and instead use x . x *x < y in place of х < Math.cbrt (y).
$ javac Ramanujan.java
$ java Ramanujan 40000
1729 = 1"3 + 12^3 = 9^3 + 10"3
4104 = 2^3 + 16^3 = 9^3 + 15^3
13832 = 2^3 + 24^3 = 18^3 + 20^3
39312 = 2^3 + 34^3 = 15^3 + 33^3
32832 = 4^3 + 32^3 = 18^3 + 30^3
20683 = 10^3 + 27^3 = 19^3 + 24^3
Answer:
Here the code is given as follows,
Explanation:
Code:
public class Ramanujan {
public static void main(String[] args) {
// check cmd argument
int n = Integer.parseInt(args[0]);
// checking a^3 + b^3 = c^3 + d^3
// outer loop
for (int a = 1; (a*a*a) <= n; a++) {
int a3 = a*a*a;
// no solution is possible, since upcoming a values are more
if (a3 > n)
break;
// avoid duplicate
for (int b = a; (b * b * b) <= (n - a3); b++) {
int b3 = b*b*b;
if (a3 + b3 > n)
break;
// avoid duplicates
for (int c = a + 1; (c*c*c) <= n; c++) {
int c3 = c*c*c;
if (c3 > a3 + b3)
break;
// avoid duplicates
for (int d = c; (d * d * d) <= (n - c3); d++) {
int d3 = d*d*d;
if (c3 + d3 > a3 + b3)
break;
if (c3 + d3 == a3 + b3) {
System.out.print((a3+b3) + " = ");
System.out.print(a + "^3 + " + b + "^3 = ");
System.out.print(c + "^3 + " + d + "^3");
System.out.println();
}
}

Isaac Newton devised a clever method to casily approximate the square root of a number without having
to use a calculator that has the square root function. Describe this method with illustration
Answer:
The illustration in Java is as follows:
import java.util.*;
import java.lang.Math.*;
class Main{
public static void main (String[] args){
Scanner input = new Scanner(System.in);
double num, root, temp;
num = input.nextDouble();
temp = num;
while (true){
root = 0.5 * ( (num / temp)+temp);
if (Math.abs(root - temp) < 0.00001){
break; }
temp = root; }
System.out.println("Root: "+root);
}}
Explanation:
This declares all necessary variables
double num, root, temp;
This gets input for num (i.e the number whose square root is to be calculated)
num = input.nextDouble();
This saves the input number to temp
temp = num;
This loop is repeated until it is exited from within the loop
while (true){
Calculate temporary square root
root = 0.5 * ( (num / temp)+temp);
The loop is exited, if the absolute difference between the root and temp is less than 0.00001
if (Math.abs(root - temp) < 0.00001){
break; }
Save the calculated root to temp
temp = root; }
This prints the calculated root
System.out.println("Root: "+root);
which of the following indicates that the loop should stop when the value in the quantity variable is less than the number 50
Answer:
while (quantity >= 50)
Explanation:
Required
Stop when quantity is less than 50
To do this, we make use of a while statement and the syntax is:
while (condition){ }
If the loop should stop when quantity is less than 50; then it means the loop would continue when quantity is greater or equal to 50
So, we have:
while (quantity >= 50)

Which of the following statements describes a limitation of using a computer simulation to model a real-world object or system?
a. Computer simulations can only be built after the real-world object or system has been created.
b. Computer simulations only run on very powerful computers that are not available to the general public.
c. Computer simulations usually make some simplifying assumptions about the real-world object or system being modeled.
Answer:
The answer is "Option c".
Explanation:
Computer simulation, use of a machine to simulate a system's vibration signals by another modeled system's behaviors. A simulator employs a computer program to generate a mathematical model or representation of a true system. It usually gives a lot of simplifications concerning the physical image or system that is modeled, so this statement describes the limitation of using a computer simulation in modeling a real-world object or process.
What intangible benefits might an organization obtain from the development of an
information system?
Answer:
The immaterial benefits stem from the development of an information system and cannot easily be measured in dollars or with confidence. Potential intangible advantages include a competitive need, timely information, improved planning and increased flexibility in organisation.
Explanation:
Intangible advantages
Take faster decisionsCompetitive needMore information timelyNew, better or more information availability.Lower productivity and the lack of 'think outside' employees and managers as well as greater sales include the intangible costs of such an operational environment. All these factors improve when employees spend less of their time in addressing current methods of operation and are concerned about whether they will have a job or an employer in six months or a year. The automation level envisaged in this new system should enhance the overall efficiency of management. The operative controls and design functions should be simplified by tight system integrations with accessible automated database sources. However, it is difficult to describe the exact form of these simplifications.
Tangible costs of the new system include costs of analysis, design and construction of the system, such as the recruitment of contractors or new employees, and the assignment of existing staff. Also consideration shall be given to hardware, software purchased and operating costs. Intangible costs include disturbances to the current activities caused by development and deployment and potential adverse effects on the morals of employees.
While the new system may feel good in the long term, short-term stress and other negative consequences will still be present. In the way that Reliable does virtually everything, the system is the focus of a major change. An organisation's monumental change has widespread negative effects on operations and employees.
Q. 2. What will be the output of the following code?
//printf("Hello\n");
printf("Girls");

Telecommunications and software development are examples of information technology careers.
True
False
Answer:
True
Explanation:
Information technology may be described as the use of systems to aid application designs capable of sending and receiving information and building a communication pathway for individuals and companies. It also involves retrieving, storing large chunks of information and organizational data usually in databases to fast track the seamless functioning of the organization's system. The information technology ecosystem is very broad from those charged with ensuring effective communication such as telecommunications platforms and those who build and develop technologies for effective communication and data storage. Hence, both Telecommunications and software development are examples of information technology careers.
Create a list of lists, named hamsplits, such that hamsplits[i] is a list of all the words in the i-th sentence of the text. The sentences should be stored in the order that they appear, and so should the words within each sentence. Regarding how to break up the text into sentences and how to store the words, the guidelines are as follows: Sentences end with '.', '?', and '!'. You should convert all letters to lowercase. For each word, strip out any punctuation. For instance, in the text above, the first and last sentences would be: hamsplits[0] == ['and', 'can', 'you', 'by', ..., 'dangerous', 'lunacy'] hamsplits[-1] == ['madness', 'in', 'great', ..., 'not', 'unwatchd', 'go']
Answer:
Explanation:
The following code is written in Python. It takes in a story as a parameter and splits it into sentences. Then it adds those sentences into the list of lists called hamsplits, cleaned up and in lowercase. A test case is used in the picture below and called so that it shows an output of the sentence in the second element of the hamsplits list.
def Brainly(story):
story_split = re.split('[.?!]', story.lower())
hamsplits = []
for sentence in story_split:
hamsplits.append(sentence.split(' '))
for list in hamsplits:
for word in list:
if word == '':

Find the basic period and basic frequency of the function g(t)=8cos(10πt)+sin(15πt)
Answer:
The period is
[tex]\frac{2\pi}{5} [/tex]
The frequency is
[tex] \frac{5}{2\pi} [/tex]
Explanation:
The period of both functions will be LCM of both period.
The period of cos is
[tex] \frac{\pi}{5} [/tex]
The period of sin is
[tex] \frac{2\pi}{15} [/tex]
Let convert each into degrees.
[tex] \frac{\pi}{5} = 36[/tex]
[tex] \frac{2\pi}{15} = 24[/tex]
Find the least common multiple between 36 and 24, which is 72.
Convert 72 into radians
[tex]72 = \frac{2\pi}{5} [/tex]
The period is 2pi/5.
The frequency is equal to
1/period.
so the frequency is
[tex] \frac{1}{ \frac{2\pi}{5} } = \frac{5}{2\pi} [/tex]

Clocks (also called timers) are essential to the operation of any multiprogrammed system. They maintain the time of day, and prevent one process from monopolizing the CPU. How are clocks implemented
Answer:
The answer is below
Explanation:
The clock in the CPU is made of three elements including the following:
1. Crystal oscillator
2. A counter
3. A holding register
All these clock elements combined and generate interrupts at known periods or duration.
However, the clock has a powered battery back up which is implemented with a form of low-power circuitry similar to that of digital watches.
The purpose is to prohibit the current time from being failed when the computer is powered off or shut down.

Solve the following linear program graphically (each line represents one unit). The feasible region is indicated by the shading and the corner points have been listed for you. Determine the objective function value at the corner points and indicate the optimal solution (if any). Minimize: Z
Answer:
(a): The value of the objective function at the corner points
[tex]Z = 10[/tex]
[tex]Z = 19[/tex]
[tex]Z = 15[/tex]
(b) The optimal solution is [tex](6,2)[/tex]
Explanation:
Given
[tex]Min\ Z = X_1 + 2X_2[/tex]
Subject to:
[tex]-2X_1 + 5X_2 \ge -2[/tex] ---- 1
[tex]X_1 + 4X_2 \le 27[/tex] ---- 2
[tex]8X_1 + 5X_2 \ge 58[/tex] --- 3
Solving (a): The value of the at the corner points
From the graph, the corner points are:
[tex](6,2)\ \ \ \ \ \ (11,4)\ \ \ \ \ \ \ \ (3,6)[/tex]
So, we have:
[tex](6,2)[/tex] ------- Corner point 1
[tex]Min\ Z = X_1 + 2X_2[/tex]
[tex]Z = 6 + 2 * 2[/tex]
[tex]Z = 6 + 4[/tex]
[tex]Z = 10[/tex]
[tex](11,4)[/tex] ------ Corner point 2
[tex]Min\ Z = X_1 + 2X_2[/tex]
[tex]Z = 11 + 2 * 4[/tex]
[tex]Z = 11 + 8[/tex]
[tex]Z = 19[/tex]
[tex](3,6)[/tex] --- Corner point 3
[tex]Min\ Z = X_1 + 2X_2[/tex]
[tex]Z = 3 + 2 * 6[/tex]
[tex]Z = 3 + 12[/tex]
[tex]Z = 15[/tex]
Solving (b): The optimal solution
Since we are to minimize Z, the optimal solution is at the corner point that gives the least value
In (a), the least value of Z is: [tex]Z = 10[/tex]
So, the optimal solution is at: corner point 1
[tex](6,2)[/tex]

A python code only runs the except block when _____. Group of answer choices all the statements in the try block are executed an error occurs in the preceding try block the programmer manually calls the except block an error occurs anywhere in the code
Answer:
Python only running exception block when try block fails
Explanation:
i do cyber security and i was learning this in high school
In Python, try and except statements are used to catch and manage exceptions. Statements that can generate exceptions were placed within the try clause, while statements that handle the exception are put within the except clause.
An exception should be caught by except block, which is used to test code for errors that are specified in the "try" block. The content of the "except" block is executed if such a fault/error appears.In Python, the exception block only runs when an error occurs in the try block.Therefore, the answer is "try block fails ".

What is the function of hard disk Which Computer was the first Computer to be developed
Answer:
The hard disk is a storage device designed to permanently store data, being secondary to the software in the computer. The ENIAC was the first modern computer to be developed and built, completing construction in 1946 and taking three years to build, but if ancient computers (people who computed by hand) are factored in, then the first computer would be way back in time, perhaps even extending to the B.C. years.
