A backup can be installed that costs​ $100. What is the minimum allowable reliability for the backup that would make installing it​ worthwhile? The minimum allowable reliabilit​ = nothing​%
Answer:
0.95
Explanation:
Reliability is a assurance that a machine would have an efficiency of one or close to one.
The minimum allowable reliability R;
(1 - R) x 2000 = 100
Make R the subject of the formula;
R = 1 - (100/ 2000)
R = 1 - 0.05
= 0.95

g 'write a function that takes as input a list and outs a new list containing all elements from the input
Answer:
def mylist(*args):
return args
new_list = mylist(2,3,4,5)
Explanation:
The simple python code above defines a function called mylist that receives multiple length of element as a list and returns the list a new list. The "*args" allows the function to receive any number of item and converts them to a list that is returned in the next statement.
The can also be achieved by simply assigning a squared bracket enclosed list to the variable or with the list() constructor.
1) Write a command line that recursively copy the directories and files inside /etc to your home directory. g
Answer:
cp -R /etc /home
Explanation:
The command statement above is a Linux command line statement used to copy the directories and subdirectories of the /etc folder.
The 'cp' command is used to conventionally copy files and folders but with the '-R' flag, the specified folder is copied recursively. To copy a folder to another recursively, use the syntax;
cp -R <source folder> <destination folder>
Write a loop to print all elements in hourly_temperature. Separate elements with a -> surrounded by spaces. Sample output for the given program: (must be in python)
90 -> 92 -> 94 -> 95
Note: There is a space after 95.
------------------------------------------------------------------------------------------------------------------------
hourly_temperature = [90, 92, 94, 95]
for temp in hourly_temperature:
for index,temp in enumerate(str(temp)):
if index != len(temp)-1:
print(temp,'->',end=' ')
else:
print(temp, end='')
print('') # print newline
------------------------------------------------------------------------------------------------------------------------
My expected out is:
90 -> 92 -> 94 -> 95
I keep getting:
90 -> 92 -> 94 -> 95 ->
NOTE: I can't edit the last line "print('') #print newline"
Answer:
Following are the code to this question:
hourly_temperature = [90, 92, 94, 95]#defining a list that holds values
c= 0#defining a variable c
for temp in hourly_temperature:#defining a for loop to count list values
c+= 1#defining c variable to increment the value of c
for index,temp1 in enumerate(str(temp)):#defining for loop for spacing the list value
if index == len(str(temp))-1 and c!= len(hourly_temperature):#defining if block that checks the length of list
print(temp1,'->',end=' ')#print value
elif c == len(hourly_temperature) and index == len(str(temp)) - 1:#defining elif block that checks the length of list
print(temp1, end=' ')#print value
else:#defining else block
print(temp1, end='')#print value
Output:
90 -> 92 -> 94 -> 95
Explanation:
In the above-given code, a list "hourly_temperature" is declared, in which an integer variable c is declared, that holds an integer value that is equal to 0, and two for loop is declared, and in the first loop is used for count list value, and inside the for loop is uses enumerate method to assigns an index for each item and use the conditional statement to check each list value and provide space in each element value.

Write a test program that prompts the user to enter a two dimensional array and displays the location of the smallest element in the array.
Answer:
def element_loc():
is_end = 'n'
dimen2 = []
while is_end == 'n':
par1 = input("Enter rows and columns: ").split(",")
part = [int(i) for i in par1]
dimen2. append(part)
is_end = input("Do you want to add more rows? y/n: ")
mini = list()
for i in dimen2:
mini. append(min(i))
result = min(mini)
row_index = mini. index(result)
col_index = dimen2[row_index]. index(result)
print("Row: ", row_index, "Col_index: ", col_index)
element_loc()
Explanation:
The python program solution above prompts users for the two-dimensional array and then the rows of the array are compared with the minimum value stored in another list or array. The row index and the column index are gotten from the mini and dimen2 arrays respectively and are displayed as the position of the minimum value in the two-dimensional array.

What are the advantages and disadvantages of using steganography versus symmetric or asymmetric encryption
Explanation:
Steganography is a technique used in securing or hiding sensitive information by encrypting the information in a non-hidden file like a JPEG format. A major advantage of this method is that it reduces the risk of attack or break-in since the data is enclosed in a non-secure file; thereby reducing threats of any hack. One main disadvantage of this method is that the hidden message may become difficult to recover if the source file (non-secure file) used, is edited or deleted.
In symmetric or asymmetric encryption they both employ cryptographic encryption method. While symmetric encryption uses one key to encrypt and decrypt data, asymmetric encryption uses two keys (one for encryption, the other for decryption) of the data. A major advantage of using these methods is that they provide more security. Although while symmetric encryption is faster, asymmetric encryption is slower (eg using separate keys to gain access), a disadvantage.
Advantage:
Because the content is contained throughout a non-secure file, the above strategy decreases the chance of an assault on classified info.Disadvantage:
This approach has the disadvantage that concealed information might be able to retrieve if somehow the documents have been changed or deleted as of a non-secure file.Once again to encrypt as well as decode information, symmetric encryption employs a unique key, but asymmetric encryption utilizes two different keys, something for encryption as well as someone else for decryption.
Advantage:
One such approach is superior to steganography throughout the level of protection.Disadvantage:
Because distinct keys have been needed to get access, such techniques of asymmetric encryption are considerably slower.Thus the approach above is correct.

Sales Company:
W.D. Widgets is a small company that sells widgets. They're mostly made up of salespeople who work with lots of clients.
You've taken over as the sole IT person for this company of 80-100 people.
R teils you to provision a machine for a new employee, you order the hardware directly from a business vendor.
You keep one or two machines in stock, in case of emergency. The users receive a username that you generate for them.
You then give them an orientation on how to login when they start. You currently manage all of your machines using
Windows Active Directory. The company uses only Windows computers. When a new computer is provisioned, you have
to nistallots of sales-specific applications manually onto every machine. This takes a few hours of your time for each
15
machine. When someone has an IT-related request, they email you directly to help them.
Almost all software is kept in-house, meaning that you're responsible for the email server, local machine software, and
instant messenger. None of the company's services are kept on the cloud.
Customer data is stored on a single file server. When a new salesperson starts, you also map this file server onto their
local machine, so that they can access it like a directory. Whoever creates a folder on this server owns that folder and
everything in it. There are no backups to this critical customer data. If a user deletes something, it may be lost for
everyone.

Explanation:
Write a method that reverses the sequence of elements in an array. For example, if you call the method with the array 1, 4, 9, 16, 9, 7, 4, 9, 11, then the array is changed to 11, 9, 4, 7, 9, 16, 9, 4, 1. Use one or more loops in your solution (do not use the Array Reverse method).
Answer:
The method written in Java is as follows:
public static void ArrayReverse(int myarray[]){
for(int index = myarray.length-1; index>=0;index--)
System.out.print(myarray[index]+" ");
}
Explanation:
This line defines the method
public static void ArrayReverse(int myarray[]){
This line iterates through the array from highest to least index
for(int index = myarray.length-1; index>=0;index--)
This prints the array elements in reverse
System.out.print(myarray[index]+" ");
}
To call the method from the main, use the following:
ArrayReverse(myarr);
However, myarr must be declared and populated as an integer array before the method is called
See attachment for illustration of the complete program (the main and the array reverse method)
Using direct mapping, consider a 16-bit memory addresses, and a cache with 64 blocks, where each block is 8 bytes. What is the size of offset, block, and tag
Answer:
Tag Block Offset
7 6 3
Explanation:
Using direct mapping hashing:
Memory address size = 16 bits
Number of cache blocks = 64
Size of each block = 8 bytes
Thus;
Offest field = size of each block = 2^{3} = 3 bits
Number of blocks = 64 = 2
Thus, the index field is = 2^{6} = 6 bits of block
Tag filed is of size = 16 - (3+6) = 7 bits of tag

Basically, each blocks that makes up the cache stores additional block and sometimes a bit.
Suppose that you have the following declaration:
stack Type stack(50); double num; and the input is
25 64-3 6.25 36-4.5 86 14 -129
Write a C++ code that processes this input as follows: If the number is non-negative, it pushes the square root of the number onto the stack; otherwise it pushes the square of the number onto the stack. After processing these numbers write a C++ code that outputs the elements of the stack.
Answer:
Explanation:
The code is written in C++:
#include <iostream>
#include <stack>
#include <math.h>
#include <iomanip>
using namespace std;
/*
* Supporting method to print contents of a stack.
*/
void print(stack<double> &s)
{
if(s.empty())
{
cout << endl;
return;
}
double x= s.top();
s.pop();
print(s);
s.push(x);
cout << x << " ";
}
int main(){
// Declaration of the stack variable
stack<double> stack;
//rray with input values
double inputs[] = {25,64,-3,6.25,36,-4.5,86,14,-12,9};
/*
* For each element in the input, if it is positive push the square root into stack
* otherwise push the square into the stack
*/
for(int i=0;i<10;i++){
if(inputs[i]>=0){
stack.push(sqrt(inputs[i]));
}else{
stack.push(pow(inputs[i],2));
}
}

While your hands are on home row, both of your thumbs are on Space-barI know this will definitely help✍️✍️✍️There are many different LAN technologies (Wifi, Ethernet, etc) that can be incompatible with each other in terms of how they exchange data. How is it possible then, that any source host can still send information to any destination host when connected in an internet? Explain the two important components of this process.
Answer:
Explanation:
The two most important parts of this process are simply sending and receiving the data. When a network sends data, the system breaks the data into smaller pieces called Packets. The system then checks if the network that the packets are being sent to exists, if so the packets are sent to that network. When the receiving network's router receives these packets it reconstructs all of the packets received into the final data in the format that the final LAN system can read and sends it to the appropriate device.
You are configuring a firewall to use NAT. In the configuration, you map a private IP address directly to a persistent public IP address. What form of NAT is being used?
A. Registered NAT.B. Static NAT.C. Dynamic NAT.D. Advanced NAT.
Answer:
Option B (Static NAT) would be the correct choice.
Explanation:
Static NAT seems to be a method of NAT methodology used to navigate as well as monitor internet usage from some kind of specific public IP address to something like a private IP address. Everything always allows the provision of web access to technology, repositories including network equipment inside a protected LAN with an unauthorized IP address.Some other decisions made aren't relevant to the situation in question. So the above alternative is indeed the right one.
Insert the missing code in the following code fragment. This fragment is intended to implement a method to set the value stored in an instance variable.
Public class Employee
{
Private String empID;
Private boolean hourly;

{
Hourly = isHourly;
}
}
A) public void setHourly(String isHourly)
B) public void getHourly()
C) public boolean getHourly()
D) public boolean setHourly(boolean isHourly)
Answer:
A)
Explanation:
In this code example the missing piece of code would be...
public void setHourly(String isHourly)
This piece of code is creating a function called setHourly which takes in one String variable as it's parameter. Based on the rest of the code, the function takes that parameter variable and places it into an instance variable called Hourly which can be used when the function is called.
What single awk command can be used to display all the login names and their associated numerical user IDs
Answer:
Used the command syntax; awk -F":" '{ print "username: " $<number location> "\t\tuid:" $<number location> }' <target folder>
Explanation:
Linux operating system is a fast open-source computer platform for programmers and network administrators. Its system is arranged in a hierarchical tree structure with the root represented as "/" (for absolute path).
The passwd is a folder in the Linux OS that holds the login details of all users in the system network. The 'awk' is one of the commands used to get information from a file in a folder. It prints out the result by specifying the location of the values (like the username and user id) as a variable (with prefix '$') and then the target folder.
To prevent long page load times for pages containing images, it is best to use a compressed file format such as JPG, as well as appropriate image dimensions and
resolution.
magnification.
orientation.
colors.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given options to this question are:
resolution. magnification. orientation. colors.The correct option to this question is 1. i.e.
Resolution.
The resolution of an image determines how many pixels per inch an image contains. Image having a higher resolution takes long page load times for a page and lower resolution takes less page load time. So, to prevent long page load times for pages containing images, it is best to use compressed file formation as well as appropriate image dimension and resolution.
While other options are not correct because:
Magnification, orientation, and color does not affect the page load time. Page load time for images only affected by the dimension and resolution of the images.
