| plug and play | The computer will recognize the hardware dynamically, load a device driver for it, and make it available to the user in a short period of time. |
| preemptive multitasking | method used for applications to share a cpu with time limits and priority levels. |
| process | A term used to describe the files, memory, and application code that combine together to form a single running application. |
