what are processes and threads memory is allocated to what process or threads? what is mutex and semaphore how many threads/process can you launch at a time what is meaning of core in 4-core system what is context switching?

Question

Accepted Answer

Processes and threads are units of execution in a computer system. Memory is allocated to processes. Mutex and semaphore are synchronization mechanisms. Core refers to a processing unit in a multi-core system. Context switching is the process of switching between different processes or threads.

Processes are independent units of execution with their own memory space and resources.
Threads are lightweight units of execution within a process, sharing the same memory space.
Memory is allocated to processes, while threads within a process share the same memory space.
Mutex is a locking mechanism used to ensure exclusive access to shared resources.
Semaphore is a signaling mechanism used for synchronization between multiple threads or processes.
The number of threads/processes that can be launched at a time depends on system resources and limitations.
In a 4-core system, 'core' refers to a processing unit capable of executing instructions independently.
Context switching is the process of saving and restoring the state of a CPU to allow multiple processes or threads to run concurrently.
