Definitions:
- A system call that creates a new process by creating a logical copy of the current process.
- The part of the operating system that runs in supervisor mode on the CPU and has the code that is run for all interrupts
- A stream of bytes associated with a hierarchical name.
- The API used by a process to access outside resources (disk/user input/network)
- A variable that can only be accessed within the current shell.
- A variable that can be accessed within the current process and in child processes (unless filtered)e
- A variable that can be accessed globally by all processes.
- A process that has terminated but its parent has not retrieved its return value.
- An indexed collection of object files that may be linked into a program.
