Questions 2:-What is Database schema and its type ?


A database schema is a blueprint or structure that defines the organization, logical structure, and relationships of data stored in a database. It outlines the database’s tables, fields, keys, constraints, and relationships between tables. The schema provides a framework for organizing and accessing data efficiently, ensuring consistency and integrity within the database.

  1. Physical Schema: Describes the physical storage organization of data, including file structures and storage mechanisms.
  2. Logical Schema: Defines the logical structure of the database, including tables, columns, relationships, and constraints.
  3. Conceptual Schema: Represents the overall logical structure of the entire database system, focusing on high-level entities and their relationships.
  4. External Schema (View Schema): Creates the database schema to meet the specific needs of different user groups or applications, providing customized views of the data.
  5. Schemaless (NoSQL) Schema: Allows for flexible or non-existent schemas, commonly found in NoSQL databases, enabling the storage of unstructured or semi-structured data without predefined structures.

Questions 3:-What is memory leak in C++ ? How can we fix it ?


In C++, a memory leak occurs when memory that is dynamically allocated using `new` or `malloc` is not properly deallocated before the program terminates. This leads to a gradual depletion of available memory, potentially causing performance issues or crashes. To avoid memory leaks:

  • Use smart pointers (`std::unique_ptr`, `std::shared_ptr`) to manage memory automatically.
  • Follow the RAII principle, tying resource acquisition to object initialization and release to object destruction.
  • Minimize manual memory management and prefer standard library containers.
  • Utilize memory analysis tools like Valgrind to detect and fix memory leaks.
  •  Always free resources properly, ensuring that memory allocated with `new` is deallocated with `delete`.
  • Employ debugging techniques and monitor memory usage to catch leaks early.

Questions 4:- What is List Comprehension and Dictionaries in Python ?


List Comprehensions:

  1. List comprehensions provide a compact and efficient way to create lists in Python.
  2. They consist of an expression followed by a for loop inside square brackets, which iterates over an iterable and applies the expression to each element to generate a new list.
  3. List comprehensions can also include conditional statements for filtering elements based on certain criteria.

squares = [x2 for x in range(10)]

# Output: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]


  1. Dictionaries in Python are unordered collections of key-value pairs enclosed in curly braces {}.
  2. Each key-value pair maps a key to its corresponding value, allowing for efficient lookup and retrieval of data.
  3. Dictionaries can store a variety of data types as values, including integers, strings, lists, tuples, or even other dictionaries.

student_ages = {‘Alice’: 20, ‘Bob’: 22, ‘Charlie’: 21}
bob_age = student_ages[‘Bob’]

# Output: 22

Questions 5:- Can you tell me about ClassLoader in Java ?


In Java, the ClassLoader is a crucial component of the Java Runtime Environment (JRE) responsible for dynamically loading Java classes into memory at runtime.

It locates and loads class files from the file system, network, or other sources, converting them into Java bytecode that can be executed by the Java Virtual Machine (JVM).

Some main functionality of Class loader are:

  1. Dynamic Loading: ClassLoader loads Java classes into memory as needed during program execution, rather than loading all classes at once.
  2. Hierarchical Structure: ClassLoader follows a hierarchical structure with parent-child relationships. Each ClassLoader has a parent ClassLoader, and classes are first searched in the parent ClassLoader before the current ClassLoader.
  3. Delegation Model: ClassLoader uses a delegation model for class loading, where each ClassLoader delegates the class loading request to its parent ClassLoader before attempting to load the class itself. This model helps maintain class integrity and avoids duplicate loading of classes.
  4. Customization: Java provides the flexibility to customize ClassLoader behavior by extending the `ClassLoader` class and overriding its methods. Developers can create custom ClassLoaders to load classes from non-standard sources or implement custom class loading strategies.
  5. Security: ClassLoader plays a crucial role in Java’s security model by enforcing access controls and ensuring that classes loaded from untrusted sources do not compromise the integrity of the JVM.

Questions 9:- What is Prototype chaining ?


  1. Prototype chaining is a key concept in JavaScript’s object-oriented programming model, which enables objects to inherit properties and methods from other objects.
  2. Each object in JavaScript has an internal property called `[[Prototype]]` (accessible via `__proto__`), which references its prototype object. When you access a property or method on an object, JavaScript first checks if it exists on the object itself.
  3. If not, it looks up the prototype chain by following the `[[Prototype]]` link to the object’s prototype, and continues this process recursively until it finds the property or method or reaches the end of the chain.

Questions 10:- Name the functions used for encoding and decoding the URLs in javascript.


To encode and decode URLs in JavaScript,

TCS Prime Interview questions with answers (UG students)

Questions 11:- What are different techniques to prevent deadlocks?


  1. Mutual Exclusion:
    Ensure that resources can only be accessed by one process at a time.
  2. Hold and Wait:
    Require processes to acquire all necessary resources at once before execution to avoid holding resources while waiting for others.
  3. No Preemption:
    Avoid forcibly removing resources from processes; if a process requires additional resources, it should release what it holds and try again.
  4. Circular Wait:
    Enforce an order for resource acquisition to prevent circular waiting dependencies among processes.
  5. Resource Allocation Graph:
    Use a graph to represent resource allocation and request relationships; detect cycles to identify potential deadlocks and take preventive actions.
  6. Banker’s Algorithm:
    A deadlock avoidance algorithm that evaluates resource allocation requests to ensure that allocating resources won’t lead to an unsafe state, preventing deadlocks before they occur

Questions 12:- What do you understand about Null Pointer and Void Pointer ?


Null Pointer:

  • A null pointer is a pointer that does not point to any memory location.
  • It typically represents the absence of a valid memory address.
  • Attempting to dereference a null pointer (accessing the value it points to) usually results in a segmentation fault or access violation error, as it points to nowhere.
  • Null pointers are commonly used to indicate that a pointer does not currently point to valid data or memory.
  • In C and C++, a null pointer is represented by the literal `NULL` or `nullptr`.

Void Pointer:

  • A void pointer is a pointer that has no associated data type.
  • It can point to objects of any data type, including integers, characters, structures, or other pointers.
  • Unlike other pointers, you cannot dereference a void pointer directly, as the compiler does not know the size or type of the data it points to.
  • To use a void pointer, you typically cast it to a specific data type before dereferencing it.
  • Void pointers are often used in situations where the exact data type of the object being pointed to is unknown or varies dynamically.

Questions 13:-  What is NAT ?


  • Network Address Translation (NAT) is a process used in networking to remap one IP address space to another.
  • It involves modifying the IP headers of packets as they pass through a routing device, such as a router or firewall.
  • NAT allows multiple devices within a local network to share a single public IP address for communication with devices outside the local network, typically on the internet. This helps conserve public IP addresses and provides an additional layer of security by hiding internal IP addresses from external networks.
  • NAT can be implemented in various forms, including static NAT, dynamic NAT, and port address translation (PAT), each serving different purposes in network configuration and management.

Questions 14:-  What is Socket Programming? What Are The Benefits And Drawbacks Of Java Sockets?


Socket programming is a method of communication between two nodes on a network.
It enables bidirectional data exchange between a client and a server over a network.
In socket programming, a socket represents one endpoint of a communication channel.

Benefit of Java Sockets:

  1. Platform Independence: Java’s “write once, run anywhere” principle allows socket-based applications to run on any platform that supports Java.
  2. Versatility: Java sockets support various protocols, such as TCP and UDP, allowing developers to choose the appropriate protocol based on their application requirements.
  3. Scalability: Java sockets are scalable and can handle a large number of concurrent connections.
  4. Flexibility: Java sockets provide low-level access to network protocols, giving developers full control over the networking process. This allows for the implementation of custom networking solutions tailored to specific use cases.

Drawbacks of Java Sockets:

  1. Complexity: Socket programming in Java can be complex, especially for beginners.
  2. Concurrency: Managing concurrent connections and handling multithreading can be challenging in socket-based applications.
  3. Security: Java sockets do not provide built-in security features, such as encryption and authentication. Developers must implement additional security measures, such as SSL/TLS, to secure socket-based communication.
  4. Performance Overhead: Socket-based communication introduces overhead due to protocol processing and data serialization/deserialization. While Java sockets offer high performance, developers should be mindful of potential performance bottlenecks in their applications.

Questions 15:-  What do you understand by IPsec ?


  • IPsec, or Internet Protocol Security, is a suite of protocols used to secure Internet Protocol (IP) communications by encrypting and authenticating data packets sent over IP networks.
  • It provides security at the network layer of the OSI model and is commonly used to establish virtual private networks (VPNs) and ensure the confidentiality, integrity, and authenticity of network traffic.

Questions 16:-  What are the two integrity rules in a DBMS?


  1. Entity Integrity Rule: Also known as the primary key constraint, this rule ensures that each row (or entity) in a table is uniquely identified by a primary key. It prohibits duplicate or null values in the primary key column, ensuring that each entity is uniquely identifiable.
  2. Referential Integrity Rule: This rule ensures the consistency of relationships between tables in a database. It requires that foreign key values in one table must match primary key values in another table or be null. It prevents orphaned records by enforcing that any foreign key value must reference an existing primary key value in the referenced table.

Questions 17:-  What does the RR Scheduling Algorithm in OS involve?


The RR (round-robin) scheduling algorithm was initially developed for time-sharing systems. It operates by cycling through a circular queue in the CPU scheduler, granting CPU time to each task for a predetermined duration, typically ranging from 10 to 100 milliseconds.
It is known for its simplicity and straightforward implementation. The algorithm is preemptive, as processes are granted CPU time for a specific period only. Additionally, it ensures that all processes receive an equal portion of CPU time.
However, drawbacks of this approach include frequent context switches, which can impact system throughput. Moreover, it may lead to longer waiting and response times for processes.

Questions 18:-  What is DHCP?


DHCP, or Dynamic Host Configuration Protocol, is a networking protocol used to automatically assign IP addresses to devices connected to a network.

When a device joins a network, it sends a broadcast request for an IP address. A DHCP server on the network responds by assigning an available IP address to the device, along with other network configuration details such as subnet mask, default gateway, and DNS server.

This eliminates the need for manual IP address configuration on each device, simplifying network management. DHCP also helps prevent IP address conflicts by tracking which addresses are in use.

DHCP is commonly used in networks with many devices, including home networks, small businesses, and large enterprises. It’s a widely adopted protocol supported by most devices, including computers, smartphones, and IoT devices.

Questions 19:-  What are the layers in an OSI model?


The OSI (Open Systems Interconnection) model serves as a framework outlining the process of communication between various network devices. It contains 7 layers, each with its designated role:

  • Physical Layer manages the transmission of raw data bits through communication channels.
  • Data Link Layer establishes a dependable connection between two network devices.
  • Network Layer handles the routing of data across diverse networks.
  • Transport Layer ensures seamless end-to-end communication and reliable data transfer.
  • Session Layer oversees the initiation, coordination, and termination of sessions among applications.
  • Presentation Layer converts data into a format comprehensible by the application layer.
    Application Layer delivers services to applications and end-users, encompassing functions like email and file transfer.

Questions 20:-  Explain Quick Sort Algorithms with examples.


Quick sort is a popular sorting algorithm that follows the divide-and-conquer strategy. 
Here’s how it works,


  •  Choose a pivot element from the array (commonly the first or last element).
  • Partition the array into two parts: elements less than the pivot and elements greater than the pivot.
  • Recursively apply the above steps to the two partitioned arrays until the entire array is sorted.
  • Combine the sorted partitions to obtain the final sorted array.


Sorting the array [4, 2, 7, 1, 3, 5, 6] using quick sort.

  1. Choose the pivot (let’s say the first element, 4).
  2. Partition the array into two parts: [2, 1, 3] and [7, 5, 6].
  3. Apply quick sort recursively to both partitions.
  4. Repeat the process until each partition contains only one element.
  5. Combine the sorted partitions to obtain the final sorted array: [1, 2, 3, 4, 5, 6, 7].
Pseudo Code:
QuickSort(arr, low, high):
if low < high:
    pivot_index = partition(arr, low, high)
    QuickSort(arr, low, pivot_index 1)
    QuickSort(arr, pivot_index + 1, high)

partition(arr, low, high):
pivot = arr[low]
left = low + 1
right = high
done = false
while not done:
    while left <= right and arr[left] <= pivot:
        left = left + 1
    while arr[right] >= pivot and right >= left:
        right = right 1
    if right < left:
        done = true
        swap arr[left], arr[right]
swap arr[low], arr[right]
return right

Questions 21:-  What are ACID properties in DBMS ?


ACID properties are fundamental principles in database management systems (DBMS) that ensure the reliability and consistency of transactions.

  1. Atomicity: Transactions are treated as indivisible units of work. Either all operations within a transaction are successfully completed, or none of them are. If a transaction fails or encounters an error, it is rolled back to its original state, ensuring data integrity.
  2. Consistency: Transactions bring the database from one consistent state to another. All integrity constraints, such as primary key, foreign key, and check constraints, must be maintained before and after transaction execution. This ensures that the database remains in a valid state at all times.
  3. Isolation: Transactions are executed independently and are isolated from each other to prevent interference or data corruption. Concurrent transactions do not see each other’s intermediate states, and their operations are executed as if they were the only transaction running. This prevents issues like dirty reads, non-repeatable reads, and phantom reads.
  4. Durability: Once a transaction is committed, its changes are permanent and are guaranteed to persist, even in the event of system failures or crashes. The committed data is stored in non-volatile storage, such as disk or SSD, ensuring that it remains available and intact for future transactions.

These ACID properties ensure the reliability, consistency, and durability of transactions in a DBMS, providing a solid foundation for data integrity and concurrency control.

They are essential for maintaining the trustworthiness of databases in various applications, including banking systems, e-commerce platforms, and enterprise resource planning (ERP) systems.

Questions 22:-  What is the Weights file in python ?


A weights file, in the context of machine learning and deep learning, is a file that contains the learned parameters (also known as weights) of a neural network model after it has been trained on a dataset. These parameters include the weights and biases of the neurons in the network’s layers.

During the training process, the neural network learns to adjust these parameters to minimize the difference between its predictions and the actual target values of the training data. Once the training is complete, the optimal values of these parameters are saved in a weights file.

Weights files are typically saved in formats that can be easily loaded and used by machine learning frameworks and libraries, such as TensorFlow (.h5), PyTorch (.pth), or in other formats like TensorFlow’s SavedModel format (.pb) or ONNX (.onnx).

Questions 23:-  What is the basic idea behind OOPs Concept ?


OOP (Object-Oriented Programming) is a programming approach based on four main concepts:

  • Encapsulation: Bundling data and methods into objects to control access and ensure data integrity.
  • Inheritance: Allowing classes to inherit properties and behaviors from other classes, promoting code reuse.
  • Polymorphism: Treating objects of different classes through a common interface, enabling flexibility and extensibility.
  • Abstraction: Hiding implementation details and exposing only essential features to simplify complex systems.

These concepts help organize code, improve reusability, and make software more scalable and maintainable.

Questions 24:-  What is the basic idea behind OOPs Concept ?


Machine Learning (ML) is a branch of artificial intelligence (AI) that focuses on developing algorithms and models that enable computers to learn from data and make predictions or decisions without being explicitly programmed. There are three main types of machine learning:

  1. Supervised Learning: In supervised learning, the algorithm is trained on labeled data, meaning the input data is paired with the corresponding correct output.
    The algorithm learns to map input to output by generalizing from the labeled examples. Common applications include image classification, speech recognition, and predicting housing prices.
  2. Unsupervised Learning: Unsupervised learning involves training algorithms on unlabeled data to discover patterns or structure within the data. The algorithm learns to find similarities, groupings, or anomalies in the data without explicit guidance. Clustering, dimensionality reduction, and anomaly detection are common tasks in unsupervised learning.
  3. Reinforcement Learning: Reinforcement learning involves training an agent to make sequential decisions by interacting with an environment. The agent receives feedback in the form of rewards or penalties based on its actions, and it learns to maximize cumulative rewards over time. Reinforcement learning is used in applications such as game playing, robotics, and autonomous driving.

Questions 27:-  What do you understand by Scheduling in OS?


Scheduling in operating systems refers to the process of determining which processes or threads are allocated CPU time and in what order.

Primary goal of scheduling is to maximize CPU utilization, ensure fairness among processes, and optimize system performance.

In a multitasking environment where multiple processes or threads compete for CPU resources, a scheduling algorithm is responsible for selecting the next process or thread to execute. This decision is based on various factors, including the priority of the process, its CPU burst time, the scheduling policy, and the state of the system.

Some Common scheduling algorithms include:

  1. First-Come, First-Served (FCFS): This algorithm selects processes in the order they arrive in the ready queue. It is simple but may lead to poor average waiting times, especially for long-running processes.
  2. Shortest Job Next (SJN) or Shortest Job First (SJF): This algorithm selects the process with the shortest CPU burst time next. It minimizes average waiting time but requires knowledge of the burst times, which may not be available in practice.
  3. Round Robin (RR): This algorithm allocates CPU time to each process in a circular manner, with a fixed time quantum (slice). If a process does not complete within its time quantum, it is preempted and placed back in the ready queue.
  4. Priority Scheduling: This algorithm selects processes based on their priority. Higher priority processes are executed before lower priority ones. However, it may lead to starvation if lower priority processes are constantly preempted.
  5. Multi-Level Queue (MLQ) or Multi-Level Feedback Queue (MLFQ): This algorithm divides processes into multiple queues based on criteria such as priority or process characteristics. Processes are then scheduled within and between queues using different scheduling policies.
  6. Priority-Based Preemptive Scheduling: Similar to priority scheduling, but with preemptive behavior. Higher priority processes can preempt lower priority ones, ensuring timely execution of critical tasks.

Questions 28:-  Tell me about TCP/IP model ?


The TCP/IP protocol, which stands for Transmission Control Protocol/Internet Protocol, helps us determine the most efficient way to connect a specific computer to the internet and transfer data between them.

By linking multiple computer networks, TCP/IP allows for the creation of virtual networks, facilitating communication over large distances.

This protocol is designed with a connection-oriented approach to ensure reliable data transmission.

The TCP/IP model is a framework for computer communication over the internet, consisting of different layers, this model consists of:

  1. Application Layer: Manages how programs communicate on your computer, such as email or web browsers connecting to the internet.
  2. Transport Layer: Ensures error-free data transfer between locations, acting like a virtual delivery service to ensure messages arrive correctly and in order.
  3. Internet Layer: Determines the best route for data to travel across the internet, functioning as a GPS for data to reach its destination efficiently.
  4. Network Access Layer: Handles the physical connection between your computer and the internet, like cables and Wi-Fi signals connecting your device to the network.
