Answer:
keylogger.
Explanation:
A keylogger can be defined as a software program or hardware device designed for monitoring and recording the keystrokes entered by an end user through the keyboard of a computer system or mobile device.
Basically, a keylogger can be installed as a software application or plugged into the USB port of a computer system, so as to illegally keep a record of all the inputs or keys pressed on a keyboard by an end user.
In order to prevent cyber hackers from gaining access to your keystrokes, you should install an anti-malware software application such as Avira, McAfee, Avast, Bitdefender, Kaspersky, etc.
An antivirus utility is a software application or program that's used to scan, detect, remove and prevent computer viruses such as Malware, Trojan horses, keyloggers, botnets, adwares etc.
In conclusion, a bot can use a keylogger to capture keystrokes on the infected machine to retrieve sensitive information.

(True/False). In an "ID" column with the data type INTEGER PRIMARY KEY, each value entered for the ID must be unique.
Answer:
The answer is "True".
Explanation:
The key to a relational database that is unique for each data record is a primary key, also called a primary keyword.This unique identifier, including a driver's license name, telephone number, or vehicle identification number. This is an identifier (VIN).There must always be the only primary key in such a relational database.This is a specific relational database field (or column combination) that identifies each table entry in a unique way.It utilized it to swiftly analyze the data within the table as a unique identifier.Calculate the total time required to transfer a 500KB file in the following cases. Assume an RTT of 50ms, a packet size of 2KB, and an initial 2xRTT of handshaking before data is sent. A. If the bandwidth is 2Mbps, what is the Bandwidth-Delay Product (BDP)
Answer:
i) Total time = 2457.73 secs
ii) BDP = 0.01 Mbyte
Explanation:
Packet size : 2 Kb = ( 2 * 8192 ) bits = 16384 bits
Bandwidth : 2Mbps = 2,000,000 bits/sec
RTT = 50 ms = 0.050 secs
i) Determine total time required to transfer 500 kB
= Initial handshake + Time for transmission of all files + propagation delay
= 2 x RTT + Time for transmission + RTT /2
Total time = ( 2 * 0.05 ) + (1500 * 1.6384 )+ ( 0.050 / 2 ) = 2457.73 secs
ii) Determine the Bandwidth-delay product
= data link capacity * RTT
= 2 Mbps * 50 ms = 100,000 = 0.01 MByte

A company is deploying NAFDs in its office to improve employee productivity when dealing with paperwork. Which of the following concerns is MOST likely to be raised as a possible security issue in relation to these devices?
A. Sensitive scanned materials being saved on the local hard drive
B. Faulty printer drivers causing PC performance degradation
C. Improperly configured NIC settings interfering with network security
D. Excessive disk space consumption due to storing large documents
Answer:
D. Excessive disk space consumption due to storing large documents.
Explanation:
When a company is planning to use NAFDs in its office rather than paper work, the efficiency of employees will increase as unnecessary paper work takes time in handling and printing. When data is stored on disks there is a risk that employees store large or irrelevant files in the disk which will create storage issues.
Peter is a new business owner. Because Peter is on a strict budget, he uses an older Novell NetWare server. The NetWare server still relies on the legacy IPX/SPX network protocol suite. Peter needs to connect his server to the Internet. He decides to use a gateway instead of a router. What is the likely motive behind Peter's decision
The most likely motive of Peter's decision to use a gateway for connecting his serve to the internet is to get a wireless connection for the internet.
A gateway server is used to communicate to the internet service provider. It is used to receives the data. It helps to sends the data to the router in order to translate as well as distribute the wireless devices.
In the context, Peter who is on a strict budget uses gateway system to connect to the internet and he uses the older version of Novell NetWare server.

write a programmimg code in c++ for school based grading system, the program should accept the subject in the number of students from a user and store their details in the array of type student(class) the student class you have:
1. number student name, index number remarks as variables of type string, marks as integer and grade as char.
2. avoid function called getData which is used to get student details
3. avoid function called calculate which will work on the marks and give the corresponding great and remarks as given below on
Marks 70-100 grade A remarks excellent Mark 60-69 Grade B remarks very good marks 50-59 grade C remarks pass maths 0-49 grade F remarks fail
Answer:
The program is as follows:
#include <iostream>
#include <string>
using namespace std;
class Student{
string studName, indexNo, remarks; int marks; char grade;
public:
void getData(){
cin.ignore();
cout<<"ID: "; getline(cin,indexNo);
cout<<"Name:"; getline(cin,studName);
cout<<"Marks: ";cin>>marks; }
void calculate(){
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
cout << "Grade : " << grade << endl;
cout << "Remark : " << remarks << endl; }
};
int main(){
int numStudents;
cout<<"Number of students: "; cin>>numStudents;
Student students[numStudents];
for( int i=0; i<numStudents; i++ ) {
cout << "Student " << i + 1 << endl;
students[i].getData();
students[i].calculate(); }
return 0;}
Explanation:
This defines the student class
class Student{
This declares all variables
string studName, indexNo, remarks; int marks; char grade;
This declares function getData()
public:
void getData(){
cin.ignore();
Prompt and get input for indexNo
cout<<"ID: "; getline(cin,indexNo);
Prompt and get input for studName
cout<<"Name:"; getline(cin,studName);
Prompt and get input for marks
cout<<"Marks: ";cin>>marks; }
This declares funcion calculate()
void calculate(){
The following if conditions determine the remark and grade, respectively
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
This prints the grade
cout << "Grade : " << grade << endl;
This prints the remark
cout << "Remark : " << remarks << endl; }
};
The main begins here
int main(){
This declares number of students as integer
int numStudents;
Prompt and get input for number of students
cout<<"Number of students: "; cin>>numStudents;
This calls the student object to declare array students
Student students[numStudents];
This is repeated for all students
for( int i=0; i<numStudents; i++ ) {
Print number
cout << "Student " << i + 1 << endl;
Call function to get data
students[i].getData();
Call function to calculate
students[i].calculate(); }
return 0;}

Answer:
"In inner for loop" is printed twice.
Answer: C. 2
Explanation:
Code:
int main()
{
int limit = 0;
for (int i =0; i>=limit; i-=2) {
for (int j = i; j <= 1; ++j){
cout << "In inner for loop" << endl;
}
cout << "In outer for loop" << endl;
}
return 0;
}
Output:
In inner for loop
In inner for loop
In outer for loop
The output "In inner for loop" print twice.
Thus, option (c) is correct.
In the given code example, the inner for loop has a condition j <= 1.
This condition means that the loop will execute as long as j is less than or equal to 1.
However, the initial value of j is i, and the value of i decreases by 2 in each iteration of the outer for loop.
When i = 8, the inner loop has the condition j ≤ 1.
The loop will iterate as long as j is less than or equal to 1.
So the inner loop executes twice: once when j = 8, and then when j = 9. The statement "In inner for loop" prints twice.
Therefore, the output print twice.
Thus, option (c) is correct.

An engineer is configuring AMP for endpoints and wants to block certain files from executing. Which outbreak control method is used to accomplish this task
Question Completion with Options:
A. device flow correlation
B. simple detections
C. application blocking list
D. advanced custom detections
Answer:
The outbreak control method that is used to accomplish the task of configuring AMP for endpoints and to block certain files from executing is:
C. application blocking list
Explanation:
The application blocking list creates a list of application files, which the AMP continuously tracks and analyzes to compare the file activities with previous cyber attacks. Specifically, the AMP for Endpoints is a cloud-managed endpoint security solution, which provides a retrospective alert to prevent cyber-security threats, and rapidly detects, contains, and remediates malicious files on the endpoints.
continuously tracks and analyzes files and file activities across your systems, and compares these events to what preceded or happened in past attacks. If a file exhibits malicious behavior, the AMP provides you with a retrospective alert which enables you to stop a potential threat from succeeding.

what is incremental development and its importance in a project
Answer:
Incremental development in software engineering is a process methodology that emphasizes the virtue of taking small steps toward the goal.
Explanation:
Rather than delaying feedback until final delivery when time and resources have already been spent, incremental development ensures that teams can use feedback to make changes early and often.
The main importance of the Incremental model is that it divides the software development into submodules and each submodule is developed by following the software development life cycle process SDLC like Analysis, Design, Code, and Test.
Answer:
incremental development is any combination of both iterative design or iterative method and incremental build model for development
Explanation:
importance
Incremental development ensures that developers can make changes early on in the process rather than waiting until the end when the allotted time has run out and the money has been spent.
An incremental approach breaks the software development process down into small, manageable portions known as increments. Each increment builds on the previous version so that improvements are made step by step
