Cognizant GenC Interview Questions

Cognizant genc interview questions for freshers easily build their career with techinical background.

1. What is the difference between Database and Database Management System?

A database may be defined as a planned collection of figures known as data.

DBMS, which stands for Database Management Systems, refers to programs that are meant to allow users to communicate with other applications.

2. Give a detailed explanation of static and dynamic memory management. Which kind should you use?

A program cannot update memory while it is executing thanks to static memory allocation. A program’s memory can be changed while it is running due to dynamic memory allocation. Static memory allocation is preferred in an array. Dynamic memory allocation is preferred for linked lists.

3. What is the distinction between Overloaded and Override methods?

Overloading is the term for when two or more methods in the same class have the same name but distinct parameters.

Overriding is the process of using the same method signature (name and arguments) in both the superclass and the child class.


public int addNumber(int a, int b){
    return a+b;
//Overloaded addNumber method with 3 parameter
public int addNumber(int a, int b, int c){
    return a+b+c;
class InterviewBit{
    public int print(){
class Scaler extends InterviewBit{
    //Overriden print method can be called based on the objects we create.
    public int print(){

4. Create a programme to determine an even or odd integer.

#include stdio.h>
int main()
    int number;
    printf("Insert a number \n");
    //Checking if the number is divisible by 2
    if (number%2 == 0)
        printf("The number is even\n");
        printf("The number is odd\n");
    return 0;

5. What is Kernel?

The kernel of an operating system is a crucial part since it regulates how both hardware and software work. In essence, it regulates the way that CPU and memory are used. The operating system must have it as a necessary component. The hardware-level data processing performed by system calls and inter-process communication is connected to programs through the kernel.

6. Explain client-server Architecture.

Client-server architecture is a type of application network that allocates tasks to clients and servers that are either connected via a network or are a part of the same system. To use the service provided by the server, the server-client sends a request to another programme, which then sends the request to a few additional programmes, which split the work among the clients and share resources with them.

7. Describe ERP.

A genre of software known as “enterprise resource planning” (ERP) is used by firms to manage daily tasks including accounting, purchasing, project management, risk management, and compliance. A complete ERP package also includes enterprise performance management software, which helps with planning, budgeting, forecasting, and reporting an organization’s financial results.

8. What is SDLC? What are its phases?


A software project is separated into stages, and so on. An SDLC is a procedure that outlines how to create, maintain, update, or improve a particular piece of software. The life cycle goes into deeper information about the software’s quality and the full evolution process. In essence, SDLC specifies the right order of steps that must be taken during the software development process or the full cycle that the program experiences.

9. What is Trapdoor in OS?

One more of the typical Cognizant GenC interview queries. A hardware or software technique called a trapdoor is used to get around system controls. It is malicious software that allows an attacker to use remote instructions to obtain unauthorised access to a network or computer system. A specific User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) port is watched by trap door software for orders.

10. Describe the differences between data mining and OLAP.

OLAP is a reporting solution that employs online analytical processing to comprehend the dimensions, content, and structure of your database. You may then decide more effectively which data to preserve and which to remove. It may also be used to find data input mistakes and concerns with data integrity. Organizing your data into many tables will scale your data storage and enhance data management. Additionally, it enables you to make customised reports using various data sets.

Data mining is a process for studying data to look for recurring patterns or logical relationships between variables. Questions regarding a huge body of data that cannot be answered by looking at a single piece of data can be answered via data mining. This broader body of data might originate from a single source, such as a survey, or it can come from several sources, such as social media or sensors that gather information about our environment. Data mining may also be used to find answers to data-related issues that don’t always require a big amount of data. In order to forecast people’s hobbies or medical problems and suggest remedies, we can construct data profiles of them.

        cout << n << endl;
template< >
class PrintZeroToN<0>
    static void display()
        cout << 0 << endl;
int main()
    const int n = 10;
    PrintZeroToN< n>::display();
    return 0;



10. Print the variable’s address without using a pointer.

#include < stdio.h>
int main()
    int x;
