Q2. What are the map, filter, and reduce functions in Python, and how are they used?
Ans. 
Map, filter, and reduce are functional programming tools in Python for processing iterables efficiently.
• map(function, iterable): Applies a function to all items in an iterable. Example: map(lambda x: x**2, [1, 2, 3]) results in [1, 4, 9].

• filter(function, iterable): Filters items in an iterable based on a function that returns True or False. Example: filter(lambda x: x > 2, [1, 2, 3, 4]) results in [3, 4].

• reduce(func...read more

Q3. What is the method for using list comprehension in Python?
Ans. 
List comprehension provides a concise way to create lists in Python using a single line of code.
• Syntax: [expression for item in iterable if condition]

• Example: squares = [x**2 for x in range(10)] creates a list of squares from 0 to 9.

• You can include conditions: evens = [x for x in range(10) if x % 2 == 0] filters even numbers.

• List comprehension can also be nested: pairs = [(x, y) for x in range(3) for y in range(3)] cre

Q1. What is circuit breakers
Ans. 
Circuit breakers are electrical switches designed to protect electrical circuits from damage caused by overload or short circuit.
• Circuit breakers automatically stop the flow of electricity when a fault is detected.

• They can be reset manually after tripping.

• Common types include thermal-magnetic, magnetic, and thermal circuit breakers.

• Examples include miniature circuit breakers (MCBs) and molded case circuit breakers (MCC

Q3. What is difference neutral or earthing
Ans. 
Neutral is a current-carrying conductor that completes the circuit, while earthing is a safety measure to prevent electric shock.
• Neutral wire carries current back to the source in a circuit

• Earthing provides a path for fault currents to flow safely to the ground

• Neutral wire is typically connected to the center tap of a transformer

• Earthing is done by connecting metal parts of electrical equipment to the earth

Q4. What is star or delta
Ans. 
Star and delta are two types of connections used in electrical circuits.
• Star connection is a type of electrical connection where all the components are connected at a common point, forming a star shape.

• Delta connection is a type of electrical connection where the components are connected in a triangular shape, resembling the Greek letter delta.

• Star connection is commonly used in three-phase AC circuits, while delta con...read more

Q5. What is use contractor
Ans. 
A contractor is a person or company hired to perform work on a specific project or job.
• Contractors are hired to complete tasks that the hiring company may not have the expertise or resources to do themselves.

• Contractors can be hired for various projects such as construction, electrical work, plumbing, etc.

• Contractors are typically paid for their services based on a contract or agreement outlining the scope of work, tim

Q1. What is difference between Dependency Inversion & Dependency Injection ?
Ans. 
Dependency Inversion is a design principle where high-level modules do not depend on low-level modules, but both depend on abstractions. Dependency Injection is a design pattern where the objects are passed their dependencies rather than creating them internally.
• Dependency Inversion: High-level modules depend on abstractions, not on low-level modules. Promotes decoupling and flexibility.

• Dependency Injection: Objects ar...read more

Q2. How do you push the data from server to client
Ans. 
Data can be pushed from server to client using technologies like WebSockets, Server-Sent Events, or HTTP long polling.
• Use WebSockets for real-time bidirectional communication between server and client.

• Server-Sent Events allow server to push data to client over a single, long-lived connection.

• HTTP long polling involves the client making repeated HTTP requests to the server, which holds the response until new data is ava
