Routing protocols are used to determine the best path for data to travel between networks.
There are two types of routing protocols: distance-vector and link-state.
Distance-vector protocols are simpler but less efficient than link-state protocols.
Examples of distance-vector protocols include RIP and IGRP.
Examples of link-state protocols include OSPF and IS-IS.
Routing protocols have different metrics to determine the bes...

Layer 3 protocol is responsible for routing and forwarding data packets in a network.
Layer 3 protocol operates at the network layer of the OSI model.
It includes protocols like IP (Internet Protocol) and ICMP (Internet Control Message Protocol).
Layer 3 protocols use logical addressing to route packets between different networks.
They determine the best path for data packets to reach their destination.
Examples of Layer 3 ...
I appeared for an interview in Mar 2025, where I was asked the following questions.
The Software Development Life Cycle (SDLC) is a structured process for developing software applications.
1. Requirement Analysis: Gathering and analyzing user needs, e.g., conducting surveys.

3. Design: Creating architecture and design specifications, e.g., wireframes and UML diagrams.
4. Implementation: Writing and compiling code, e.g., ...
A Java program can count character frequency in a string using a HashMap to store characters and their counts efficiently.
Use a HashMap: Store each character as a key and its frequency as the value. Example: `HashMap<Character, Integer> frequencyMap = new HashMap<>();`
Iterate through the string: Loop through each character in the string and update its count in the HashMap. Example: `for (char c : inputStrin...
