1. Batch System a type of computing system that executes programs, each of which is submitted in
its entirety, can be grouped into batches, and executed without external interven-
tion.
2. Central Process- a component with circuitry to control the interpretation and execution of instruc-
ing Unit (CPU) tions.
3. Cloud Computing a multifaceted technology that allows computing, data storage and retrieval and
other computer functions to take place over a large network, typically the Internet.
4. Device Manager The section of the operating system responsible for controlling the use of devices.
It monitors every device, channel, and control unit and chooses the most efficient
way to allocate all of the system's devices.
5. Embedded Com- A dedicated computer system that is often part of a larger physical system, such
puter System as a jet aircraft or automobiles. Often, it must be small. fast, and able to work with
real-time constraints, fail-safe execution, and nonstandard I/O devices.
6. File Manager The section of the operating system that controls the use of files.
7. Firmware software instructions or data that are stored in a fixed or "firm" way, usually
implemented on some type of ROM.
8. Hardware The tangible machine and its components, inlcuding main memory, I/O device, I/O
channels, direct access storage devices and the central processing unit.
9. Interactive sys- a system that allows each user to interact directly with the operating system.
tem
10. Kernel the primary part of a the operating system that remains on ROM and is charged
with performing the systems most essential tasks, such as managing main memory
and disk access.
11. Main Memory
