Tech Mahindra Technical Interview Questions for Freshers
Here are some of the Tech Mahindra Technical Interview Questions and Answers you can find, which in turn will help you to prepare for the Tech Mahindra Technical Interview.
- What are the different types of memory areas allocated by the Java Virtual Machine in Java?
A. The different types of memory areas allocated by the Java Virtual Machine are as follows:
- Class(Method) Area: The Class(Method) Area maintains per-class structures such as the runtime constant pool, fields, method data, and method code
- Stack: The Java Stack is where frames are stored. It manages local variables and partial results, as well as invoking and returning methods. Each thread has its own JVM stack, which is built concurrently with the thread. Each time a method is called, a new frame is created. When a frame’s method invocation is finished, it is destroyed
- Program Counter (PC) Register: The address of the Java virtual machine instruction presently being executed is stored in the PC (programme counter) register
- Heap: This is the runtime data location where the objects’ memory is allocated.
Native Method Stack: Each and every native method used in the application is present in it
2. Differentiate between a class and an object.
A. Let us first look at the definitions of a class and an object before looking at the differences between the two:
- Class: A class is the fundamental building unit of Object-Oriented Programming. It is a user-defined data type with its own set of data members and member functions which can be accessed and used by establishing a class instance (or an object). It is the blueprint of any item. For instance, consider the class “Accountant”. There may be a lot of accounts with different names and categories, but they will all have some similar qualities, such as balances, account holder names, and so on. The account is the class, and the amount, as well as the account holder’s name, are the properties
- Object: A class’s instance is an object. Objects can be used to access all of the class’s data members and member functions. When a class is defined, no memory is allocated; nevertheless, memory is allocated when it is instantiated (that is when an object is formed). Consider the objects in the Account class: Savings account, Current account, and so on.
Now that we understand what classes and objects are, let us take a look at the differences between a class and an object:
| Class | Object |
|---|---|
| Class is a blueprint or an object factory. | Objects are instances of classes. |
| It is a logical entity. | Objects are physical entities. |
| On the creation of a class, no memory is allocated as such. Due to not being available in the memory, classes cannot be manipulated. | On the creation of an object, memory is allocated. This allows for the manipulation of objects. |
| There are no values in the class that can be linked to the field. | Each object has its own set of values that it is associated with. |
3. State the difference between the following:
- #include <file>
- #include “file”
A. The main difference between the two is in the search location for the included file of the preprocessor. The preprocessor looks for #include “file” in the same directory as the directive’s file. Normally, this approach is used to incorporate programmatically created header files. On the other hand, the preprocessor searches for #include <file> usually in search directories pre-designated by the compiler or the IDE (Integrated Development Environment) and not necessarily in the same directory as the directive’s file. In most cases, this approach is used to incorporate standard library header files.
4. What do you understand by Function Overloading?
A. Object-Oriented programming has a feature called function overloading, which allows two or more functions to have the same name but distinct parameters. Function Overloading occurs when a function name is overloaded with several jobs. The “Function” name should be the same in Function Overloading, but the arguments should be different. Polymorphism is a feature of C++ that can be used to overload functions.
An example of Function Overloading in C++ is given below:
#include <bits/stdc++.h>
using namespace std;
void foo(int n) {
cout << ” Integer Value: ” << n << endl;
}
void foo(double n) {
cout << ” Decimal Value ” << n << endl;
}
void foo(char n) {
cout << ” Character Value” << nc << endl;
}
int main() {
foo(40);
foo(452.144);
foo(“A”);
return 0;
}
5. What are Destructors in C++? Write down the syntax for a destructor in C++.
A. Destructors in C++ are instance member functions that are automatically called whenever an object is destroyed. In other words, a destructor is the last function called before an object is destroyed. It is worth noting that if an object was formed with the “new” keyword or if the constructor used the “new” keyword to allocate memory from the heap memory or the free store, the destructor should free the memory with the “delete” keyword.
Destructors are usually used to deallocate memory and do other cleanups for a class object and its class members when the object is destroyed and are called for a class object when that object passes out of scope or is explicitly deleted.
The syntax for a destructor in C++ is given below:
~constructor-name();
So, for example, if the name of the class is “Car”, the destructor of the class would be as follows (the name of the constructor would be “Car”):
~Car();
6. State some of the advantages of a DataBase Management System.
A. Some of the advantages of a DataBase Management System are as follows:
- It helps in controlling redundancy in the database
- Integrity limitations are enforced
- Ensure that data is consistent
- Easily accessible
- Unauthorized access is restricted by it
- Multiple user interfaces are available
- Backup and recovery services are available
- Due to the usage of queries, data extraction and processing are simple
7. What Does Modular Programming Mean?
a. Modular programming is the process of subdividing a computer program into separate sub-programs.
A module is a separate software component. It can often be used in a variety of applications and functions with other components of the system. Similar functions are grouped in the same unit of programming code and separate functions are developed as separate units of code so that the code can be reused by other applications.
Object-oriented programming (OOP) is compatible with the modular programming concept to a large extent. Modular programming enables multiple programmers to divide up the work and debug pieces of the program independently.
8. Can you explain the difference between file structure and storage structure?
A. File Structure: Representation of data into secondary or auxiliary memory say any device such as hard disk or pen drives that stores data that remains intact until manually deleted is known as a file structure representation.
Storage Structure: In this type, data is stored in the main memory i.e RAM, and is deleted once the function that uses this data gets completely executed.
The difference is that storage structure has data stored in the memory of the computer system, whereas file structure has the data stored in the auxiliary memory.
9. What is a linked list?
A. A linked list is a data structure that has sequence of nodes where every node is connected to the next node by means of a reference pointer. The elements are not stored in adjacent memory locations. They are linked using pointers to form a chain. This forms a chain-like link for data storage.
Each node element has two parts:
- a data field
- a reference (or pointer) to the next node.
The first node in a linked list is called the head and the last node in the list has the pointer to NULL. Null in the reference field indicates that the node is the last node. When the list is empty, the head is a null reference.
10. What is a priority queue?
A. A priority queue is an abstract data type that is like a normal queue but has a priority assigned to elements. Elements with higher priority are processed before the elements with a lower priority. In order to implement this, a minimum of two queues are required – one for the data and the other to store the priority.
11. Explain what is Quick Sort algorithm?
A. Quick Sort algorithm has the ability to sort lists or queries quickly. It is based on the principle of partition exchange sort or Divide and conquers. This type of algorithm occupies less space, and it segregates the list into three main parts.
- Elements less than the Pivot element
- Pivot element
- Elements greater than the Pivot element
12. Explain what is Skip list?
A. Skip list the method for data structuring, where it allows the algorithm to search, delete and insert elements in a symbol table or dictionary. In a skip list, each element is represented by a node. The search function returns the content of the value related to key. The insert operation associates a specified key with a new value, while the delete function deletes the specified key.
13. Mention what are the three laws of recursion algorithm?
A. All recursive algorithm must follow three laws
- It should have a base case
- A recursive algorithm must call itself
- A recursive algorithm must change its state and move towards the base case
14. Explain what is bubble sort algorithm?
A. Bubble sort algorithm is also referred as sinking sort. In this type of sorting, the list to be sorted out compares the pair of adjacent items. If they are organized in the wrong order, it will swap the values and arrange them in the correct order.
15. How many types of database languages are?
A. There are four types of database languages:
- Data Definition Language (DDL) e.g., CREATE, ALTER, DROP, TRUNCATE, RENAME, etc. All these commands are used for updating the data that?s why they are known as Data Definition Language
- Data Manipulation Language (DML) e.g., SELECT, UPDATE, INSERT, DELETE, etc. These commands are used for the manipulation of already updated data that’s why they are the part of Data Manipulation Language.
- DATA Control Language (DCL) e.g., GRANT and REVOKE. These commands are used for giving and removing the user access on the database. So, they are the part of Data Control Language.
- Transaction Control Language (TCL) e.g., COMMIT, ROLLBACK, and SAVEPOINT. These are the commands used for managing transactions in the database. TCL is used for managing the changes made by DML.
16. Define a Relation Schema and a Relation.
A. A Relation Schema is specified as a set of attributes. It is also known as table schema. It defines what the name of the table is. Relation schema is known as the blueprint with the help of which we can explain that how the data is organized into tables. This blueprint contains no data.
A relation is specified as a set of tuples. A relation is the set of related attributes with identifying key attributes
See this example:
Let r be the relation which contains set tuples (t1, t2, t3, …, tn). Each tuple is an ordered list of n-values t=(v1,v2, …., vn).
17. What are the disadvantages of file processing systems?
A. Disadvantages of file processing systems are:
- Inconsistent
- Not secure
- Difficult in accessing data
- Data isolation
- Data integrity
- Limited data sharing
- Atomicity problem
- Data redundancy
- Concurrent access is not possible
18. What is the difference between microkernel and macro kernel?
- Micro kernel: microkernel is the kernel that runs minimal performance affecting services for the operating system. In microkernel operating system all other operations are performed by the processor
- Macro Kernel: Macro Kernel is a combination of micro and monolithic kernel.
19. What are the four necessary and sufficient conditions behind the deadlock?
A. These are the 4 conditions:
- Mutual Exclusion Condition: It specifies that the resources involved are non-sharable.
- Hold and Wait Condition: It specifies that there must be a process that is holding a resource already allocated to it while waiting for an additional resource that is currently being held by other processes.
- No-Preemptive Condition: Resources cannot be taken away while they are being used by processes
- Circular Wait Condition: It is an explanation of the second condition. It specifies that the processes in the system form a circular list or a chain where each process in the chain is waiting for a resource held by the next process in the chain.
20. What is FCFS?
A. FCFS stands for First Come, First Served. It is a type of scheduling algorithm. In this scheme, if a process requests the CPU first, it is allocated to the CPU first. Its implementation is managed by a FIFO queue.
21. What is the difference between logical address space and physical address space?
A. Logical address space specifies the address that is generated by CPU. On the other hand physical address space specifies the address that is seen by the memory unit.
22. What is fragmentation?
A. Fragmentation is a phenomenon of memory wastage. It reduces the capacity and performance because space is used inefficiently.
23. Explain different types of networks.
A. Below are a few types of networks:
| Network Name | Description |
|---|---|
| PAN (Personal Area Network) | Let devices connect and communicate over the range of a person. E.g. connecting Bluetooth devices. |
| LAN (Local Area Network) | It is a privately owned network that operates within and nearby a single building like a home, office, or factory |
| MAN (Metropolitan Area Network) | It connects and covers the whole city. E.g. TV Cable connection over the city |
| WAN (Wide Area Network) | It spans a large geographical area, often a country or continent. The Internet is the largest WAN |
| GAN (Global Area Network) | It is also known as the Internet which connects the globe using satellites. The Internet is also called the Network of WANs. |
24. Describe the TCP/IP Reference Model
A. It is a compressed version of the OSI model with only 4 layers. It was developed by the US Department of Defence (DoD) in the 1980s. The name of this model is based on 2 standard protocols used i.e. TCP (Transmission Control Protocol) and IP (Internet Protocol).
25. What are Unicasting, Anycasting, Multicasting, and Broadcasting?
- Unicasting: If the message is sent to a single node from the source then it is known as unicasting. This is commonly used in networks to establish a new connection.
- Anycasting: If the message is sent to any of the nodes from the source then it is known as anycasting. It is mainly used to get the content from any of the servers in the Content Delivery System.
- Multicasting: If the message is sent to a subset of nodes from the source then it is known as multicasting. Used to send the same data to multiple receivers.
- Broadcasting: If the message is sent to all the nodes in a network from a source then it is known as broadcasting. DHCP and ARP in the local network use broadcasting
