Threads
Definition:
A thread is a lightweight process that can execute concurrently with other threads within the same operating system kernel. A thread has its own execution context, including its own stack and set of registers. Threads share resources such as memory and files with other threads, but they do not share the same memory space as processes.
Example:
Imagine a program with two threads. Thread 1 is responsible for processing a web request, while thread 2 is responsible for handling a chat window. Both threads can be running at the same time, responding to user events and performing their respective tasks.
Benefits of Threads:
Concurrency: Threads allow multiple processes to execute concurrently, improving overall system performance.
Efficiency: Threads can be created and destroyed dynamically, enabling efficient utilization of system resources.
Scalability: Threads allow systems to scale better to handle increased workloads.
Disadvantages of Threads:
Synchronization: Threads require careful synchronization mechanisms to avoid data races and race conditions.
Memory Management: Threads can have their own memory management issues, requiring proper synchronization to avoid corruption.
Debugging: Debugging threads can be challenging due to their non-deterministic behavior.
Additional Notes:
Threads can be created and joined dynamically.
A thread can be paused and resumed, allowing other threads to execute.
Threads share the same kernel resources as processes, but they have their own schedulers and priorities
