Each process in an operating system operates independently and has its own:
Open files: A process can open and access specific files without affecting other processes' file access.
Pending alarms, signals, and signal handlers: These are used for process synchronization and communication, and each process manages its own set.
Address space and global variables: This isolates a process's data and code from other processes, preventing conflicts and ensuring data integrity.
These separate resources allow for concurrent execution of multiple processes without interfering with each other.
