Technical round with questions on DBMS and Networking mainly.
- Q1. What is the difference between RDBMS and DBMS?
- Ans.
RDBMS is a type of DBMS that stores data in a structured format with relationships between tables.
RDBMS enforces referential integrity and allows for normalization of data.
DBMS is a general term for any system that manages databases, while RDBMS specifically refers to relational databases.
Examples of RDBMS include MySQL, Oracle, and SQL Server.
Examples of DBMS include MongoDB and Redis.
- Q2. What is an Object-Oriented Database Management System (OODBMS)?
- Ans.
An Object-Oriented Database Management System (OODBMS) is a type of database management system that supports the creation and management of objects in a database.
OODBMS stores data in the form of objects, which can contain attributes and methods.
It allows for complex data structures and relationships to be represented more easily.
Examples of OODBMS include db4o, ObjectDB, and ObjectStore.
- Q3. How do you find the number of unique values in a SQL database?
- Ans.
Use the COUNT DISTINCT function in SQL to find the number of unique values in a database.
Use the COUNT DISTINCT function along with the column name to count the number of unique values in that column.
For example, SELECT COUNT(DISTINCT column_name) FROM table_name;
You can also use GROUP BY to find the number of unique values for multiple columns.
- Q4. What is the difference between a hub and a switch in networking?
- Ans.
A hub operates at the physical layer and broadcasts data to all devices on the network, while a switch operates at the data link layer and forwards data only to the intended recipient.

- Q2. Reverse a linked list (iterative AND Recursive)
- Ans.
Reverse a linked list using iterative and recursive methods.
Iterative method involves traversing the list and changing the pointers to reverse the order.
Recursive method involves calling the function recursively on the next node and changing the pointers.
Both methods have O(n) time complexity and O(1) space complexity.
Example: 1->2->3->4->5 becomes 5->4->3->2->1.
- Q3. Clone a FULL linked list given a pointer and a random pointer
- Ans.
Clone a linked list with a random pointer.
Create a new node for each node in the original list.
Use a hash table to map the original nodes to their clones.
Iterate through the original list again and update the random pointers of the clone nodes.
- Q4. TELL ME ABOUT YOURSELF
