Generators and decorators are two important features in Python that help in simplifying code and improving performance.

• Generators are functions that can be paused and resumed, allowing for efficient memory usage and lazy evaluation.

• Decorators are functions that modify the behavior of other functions, adding functionality without changing the original code.

• Generators are created using the 'yield' keyword, while dec...read more

Multithreading is the execution of multiple threads of a single process, while multiprocessing is the execution of multiple processes.

• Multithreading involves multiple threads within a single process, while multiprocessing involves multiple processes.

• Multithreading shares the same memory space, while multiprocessing has separate memory spaces.

• Multithreading is suitable for I/O-bound tasks, while multiprocessing is ...read more

API stands for Application Programming Interface. REST and SOAP are two types of APIs.

• REST is an architectural style that uses HTTP protocol for communication and supports multiple data formats like JSON, XML, etc.

• SOAP is a protocol that uses XML for communication and supports only XML data format.

• REST is lightweight and easy to use, while SOAP is more complex and requires more bandwidth.

Count the characters in a given string.

• Iterate through the string and count each character

• Use a hash table to store the count of each character

• Handle edge cases such as empty string or null input

REST is an architectural style while SOAP is a protocol. REST is lightweight and uses HTTP while SOAP is XML-based and uses other protocols.

• REST is stateless while SOAP maintains state

• REST uses HTTP verbs (GET, POST, PUT, DELETE) while SOAP uses XML messaging

Load balancing is the process of distributing network traffic across multiple servers to improve performance and availability.

• Load balancing helps prevent server overload and downtime

• It can be achieved through hardware or software solutions

• Examples include round-robin, least connections, and IP hash algorithms

Java is platform independent due to its bytecode and the Java Virtual Machine (JVM) that allows execution on any OS.

• Java code is compiled into bytecode, which is platform-independent.

• The Java Virtual Machine (JVM) interprets bytecode on any operating system.

• This allows Java applications to run on Windows, macOS, Linux, etc., without modification.

• Example: A Java program compiled on Windows can run on Linux without ...read more
