10+ Indian Navy Interview Questions and Answers

OSPF is a link-state routing protocol while BGP is a path vector routing protocol.

• OSPF is used within an autonomous system, while BGP is used between autonomous systems.

• OSPF calculates the shortest path based on link cost, while BGP selects the best path based on policies and attributes.

• OSPF uses Dijkstra algorithm for routing, while BGP uses the path vector algorithm.

• OSPF is typically used in internal networks, while BGP is used for external routing and internet connectivity...read more

TCP is connection-oriented, reliable, and slower, while UDP is connectionless, unreliable, and faster.

• TCP is connection-oriented, meaning it establishes a connection before sending data.

• TCP is reliable, as it ensures all data packets are received in order and without errors.

• TCP is slower than UDP due to the overhead of establishing and maintaining connections.

• UDP is connectionless, meaning it does not establish a connection before sending data.

• UDP is unreliable, as it does no...read more

Python was developed in 1991.

• Python was created by Guido van Rossum in 1991.

• The first version of Python, Python 0.9.0, was released in February 1991.

• Python's development was motivated by the desire to have a language that was easy to read and write.

There are 7 OSI layers in the OSI model.

• There are 7 layers in the OSI (Open Systems Interconnection) model.

• Each layer has a specific function and interacts with adjacent layers.

• Examples of OSI layers include Physical, Data Link, Network, Transport, Session, Presentation, and Application layers.

Python is versatile, easy to learn, has a large community support, and is widely used in networking for automation and scripting.

• Python is versatile and can be used for a wide range of tasks in networking such as automation, scripting, and network monitoring.

• Python has a simple and readable syntax, making it easy to learn and use for network engineers.

• Python has a large community support with a vast number of libraries and frameworks available for networking tasks.

BJP stands for Border Gateway Protocol, used for routing between different autonomous systems on the internet.

• BJP is a standardized exterior gateway protocol used to exchange routing information between different autonomous systems (AS).

• It is commonly used by Internet Service Providers (ISPs) to establish routing policies and exchange network reachability information.

• BJP operates by maintaining a table of IP networks or 'prefixes' which designate network reachability among au...read more

The father of computer is considered to be Charles Babbage.

• Charles Babbage is known for his work on the Analytical Engine, a mechanical general-purpose computer.

• He is often referred to as the 'father of the computer' due to his contributions to the concept and design of programmable computers.

• Babbage's ideas and designs laid the foundation for modern computers and computing technology.

• His work influenced subsequent pioneers in the field, such as Alan Turing and Ada Lovelace.

Tim Berners-Lee developed HTML (Hypertext Markup Language).

• HTML was developed by Tim Berners-Lee in 1991.

• It is the standard markup language for creating web pages.

• HTML uses tags to structure content and define elements on a webpage.

HTML abbreviations are short forms used in HTML coding for easier and faster writing.

• HTML - HyperText Markup Language

• CSS - Cascading Style Sheets

• JS - JavaScript

• API - Application Programming Interface

SUM in window functions calculates the sum of a specified column over a window of rows.

• Calculates the sum of a specified column over a window of rows

• Can be used with other window functions like ROW_NUMBER, RANK, etc.

• Example: SELECT SUM(sales) OVER (PARTITION BY department) AS department_total_sales FROM sales_data;

Effective depth is the distance from the centroid of the tension reinforcement to the extreme compression fiber.

• It is a measure of the strength of a reinforced concrete beam or slab.

• It is calculated by subtracting the cover from the overall depth of the section.

• It is used to determine the amount of reinforcement required for a given load.

• For example, if the overall depth of a beam is 500mm and the cover is 50mm, the effective depth would be 450mm.

The neutral axis is an imaginary line passing through the centroid of a cross-section of a beam or column, where the stress is zero.

• It is the line where the bending stress is zero.

• It divides the cross-section of a beam or column into two parts, the compression zone and the tension zone.

• The position of the neutral axis depends on the shape of the cross-section.

• For example, in a rectangular cross-section, the neutral axis passes through the center of gravity of the section.

• The ...read more

C# multithreading allows multiple threads to execute concurrently, improving performance and responsiveness.

• C# provides several classes and methods for multithreading, including the Thread class and the ThreadPool class.

• Multithreading can be used to perform time-consuming tasks in the background while keeping the UI responsive.

• Synchronization primitives like locks and semaphores can be used to prevent race conditions and ensure thread safety.

• Asynchronous programming with asyn...read more
