What is the purpose of using multithreaded programming in software development?

Multithreaded programming is used to improve the performance and responsiveness of software systems. The main goals are:

• Parallel execution of tasks: Allows multiple operations to be performed simultaneously, which is especially useful on multi-core processors.
• Improving interface responsiveness: In Android, for example, long-running operations (network, database) are moved to separate threads to avoid blocking the main UI thread and causing the application to hang.
• Efficient resource utilization: Enables better use of CPU time by switching between threads when one thread is waiting (e.g., for input/output).

Example: downloading data from the internet in a background thread so that the user can continue interacting with the application without delays.
