A set of information that defines the status of resources allocated to a process is

The block of information defining the status of resources given to a process is its process description.

Process control names the general activity of managing processes, not this record.

The ALU performs arithmetic and logic, unrelated to process status.

A register unit holds small working values, not the full process status.

This description records allocated memory, files and processor state.

Add-on: the operating system uses it to switch between processes.
