1 kernel
"The core of layered architecture that manages the most basic operations of the operating system and the computer's processor. The kernel schedules different blocks of executing code, called threads, for the processor to keep it as busy as possible and coordinates multiple processors to optimize performance. The kernel also synchronizes activities among Executive-level subcomponents, such as I/O Manager and Process Manager, and handles hardware exceptions and other hardware-dependent functions. The kernel works closely with the hardware abstraction layer." -
2 MS-DOS prompt
"The visual indication from the MS-DOS command processor that the operating system is ready to accept a new command. The default DOS prompt is a path followed by a greater-than sign (for example, C:>); the user can also design a custom prompt with the PROMPT command."موجّه MS-DOS -
3 transition event
"A change in the location of processor event execution between ring 3 (user mode) and ring 0 (kernel mode). Transition events represent time spent outside the direct execution of the application code. Transition events can be time spent in threads that are not part of the profiled item, or time spent executing calls from the profiled item to the operating system." -
4 virtual machine
"A software implementation of a computer that emulates a complete hardware system, from processor to network card, in a self-contained, isolated software environment, enabling the simultaneous operation of otherwise incompatible operating systems."
