Suppose that a queue is implemented using a circular array of size 12. What is the value of last after the following operations?
10 enqueue operations
5 dequeue operations
6 enqueue operations
10 dequeue operations
8 enqueue operations
2 dequeue operations
3 enqueue operations
Last = 10

Answers

Answer 1

Answer:

10

Explanation:

An enqueue operation is a function that adds an element(value) to a queue array. A dequeue operations removes an element from a queue array. Queue arrays follow a first-in-first-out approach, so elements that are first stored in the queue are removed/accessed first(enqueue operations add elements at the rear of the queue array).

The following operations leave 10 elements in the queue of array size 12 after its done:

10 enqueue operations= adds 10 elements

5 dequeue operations= removes 5 elements( 5 elements left in queue)

6 enqueue operations= adds 6 elements(11 elements in queue)

10 dequeue operations= removes 10 elements(1 element left in queue)

8 enqueue operations= adds 8 elements(9 elements in queue)

2 dequeue operations= removes 2 elements(7 elements left in queue)

3 enqueue operations= adds 3 elements(10 elements in queue)

Therefore there are 10 elements in the queue after enqueue and dequeue operations.

3. When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested?

A. Series

B. Parallel

C. Control

D. Line

Answers

Answer:

B. Parallel

Explanation:

When using the ohmmeter function of a digital multimeter, the leads are placed parallel to the component being tested. The digital multimeter is placed parallel to the component because, current has to flow into the component so as to be able to measure its resistance. Without the flow of current in the component, the resistance could not be measured.

If the component were placed in series, there would be no way to close the circuit because, we need a closed circuit so as to measure the resistance and use the ohmmeter function of the digital multimeter.

Only a parallel connection would close the circuit.

So, B is the answer.

Answers

Answer:

4

Explanation:

Given

The attached code segment

Required

The output

The first and second lines initialize num2 to 32 and num1 to 12, respectively.

Next, the remainder is calculated on line 3

[tex]rem = 32\%12[/tex]

[tex]rem = 8[/tex]

Then the while loop is repeated as long as rem > 0.

At first, we have:

[tex]num2 = 32[/tex]

[tex]num1 = 12[/tex]

[tex]rem = 8[/tex]

The first iteration gives:

[tex]num2 = 12[/tex]

[tex]num1 = 8[/tex]

[tex]rem = 12\%8 = 4[/tex]

Is 4 > 0? Yes; The loop is executed again.

This gives:

[tex]num2 = 8[/tex]

[tex]num1 = 4[/tex]

[tex]rem = 8\%4=0[/tex]

Is 0 > 0? No; The loop is executed

The last statement prints the last value of num1;

In the last loop, we have:

[tex]num1 = 4[/tex]

Hence, the output is 4

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one.Ex: If the input is:5 2 4 6 8 10the output is:10,8,6,4,2,To achieve the above, first read the integers into a vector. Then output the vector in reverse.

Answers

Answer:

The program in C++ is as follows:

#include <iostream>

#include <vector>

using namespace std;

int main(){

   vector<int> intVect;

   int n;

   cin>>n;

int intInp;

for (int i = 0; i < n; i++) {

 cin >> intInp;

 intVect.push_back(intInp); }

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

 return 0;

}

Explanation:

This declares the vector

   vector<int> intVect;

This declares n as integer; which represents the number of inputs

   int n;

This gets input for n

   cin>>n;

This declares intInp as integer; it is used to get input to the vector

int intInp;

This iterates from 0 to n-1

for (int i = 0; i < n; i++) {

This gets each input

 cin >> intInp;

This passes the input to the vector

 intVect.push_back(intInp); }

This iterates from n - 1 to 0; i.e. in reverse and printe the vector elements in reverse

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

Switched Ethernet, similar to shared Ethernet, must incorporate CSMA/CD to handle data collisions. True False

False

Explanation:

The Carrier-sense multiple access with collision detection (CSMA/CD) technology was used in pioneer Ethernet to allow for local area networking.  Carrier-sensing aids transmission while the collision detection feature recognizes interfering transmissions from other stations and signals a jam. This means that transmission of the frame must temporarily stop until the interfering signal is abated.

The advent of Ethernet Switches resulted in a displacement of the CSMA/CD functionality.

Briefly explain what an array is. As part of your answer make use of a labelled example to show the declaration and components of an array

Answers

Answer:

Explanation:

In programming an array is simply a grouping of various pieces of data. Various data elements are grouped together into a single set and saved into a variable. This variable can be called which would return the entire set which includes all of the elements. The variable can also be used to access individual elements within the set. In Java an example would be the following...

int[] myArray = {33, 64, 73, 11, 13};

In Java, int[] indicates that the variable will hold an array of integers. myArray is the name of the variable which can be called to access the array elements. The elements themselves (various pieces of data) are located within the brackets {}

Given an array of n distinct integers sorted in ascending order, write a function that returns a Fixed Point in the array, if there is any Fixed Point present in array, else returns -1. Fixed Point in an array is an index i such that arr[i] is equal to i. Note that integers in array can be negative. Examples: #include using namespace std; void removeDivByFive(int *arr,int& size) { int index=0; for(int i=0;i

Answers

Answer:

The function is as follows:

int returnsFixed(int arr [],int n){

   int retVal = -1;

   for(int i = 0; i<n;i++){

       if(i == arr[i]){

           retVal = i;

           break;

       }

   }

   return retVal;

}

Explanation:

This defines the functionl it receives the array and the length of the array

int returnsFixed(int arr [],int n){

This initializes the return value to -1

   int retVal = -1;

This iterates through the array

   for(int i = 0; i<n;i++){

This checks if i equals arr[i]

       if(i == arr[i]){

If yes, the return value (i.e. the fixed point) is set to i

           retVal = i;

And the code is exited

           break;

       } This ends the if condition

   } This ends the iteration

This returns the calculated fixed point

   return retVal;

}

Which of the following restricts the ability for individuals to reveal information present in some part of the database?

a. Access Control
b. Inference Control
c. Flow Control
d. Encyption

Answers

Answer:

it would have to be flow control which would be C.

Explanation:

Flow Control is restricts the ability for individuals to reveal information present in some part of the database. Hence, option C is correct.

What is Flow Control?

The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.

A design concern at the data link layer is flow control. It is a method that typically monitors the correct data flow from sender to recipient. It is very important because it allows the transmitter to convey data or information at a very quick rate, which allows the receiver to receive it and process it.

The amount of data transmitted to the receiver side without any acknowledgement is dealt with by flow control.

Thus, option C is correct.
