LONG EXAM 2

5. It occurs when a pipeline has stages that require less than half a clock cycle to execute.
6. An intelligent type of DMA that is used on file servers and storage networks.
7. It is the process of matching the external symbols of a program with all exported symbols from other files, producing single binary files with no unresolved external symbols.
9. An alternative architecture that is motivated by the high cost of memory.
13. A storage device that would employ some number of inexpensive small disks instead of a single large expensive disks.
15. A human interface the requires the user to know the syntax of the system.
16. It is responsible for scheduling, synchronization, protection/security, memory management, and dealing with interrupts.
18. It allows a process to be subdivided into different threads of control.
19. A type of short-term scheduling wherein each process is allocated a certain slice of CPU time.

1. It is a 3-dimensional image rendered by the manipulation of laser beams.
2. These are external modules linked to a program in the creation of an executable module.
3. A software that provides a necessary set of functions allowing software packages to control the computer’s hardware.
4. An alternative architecture wherein its main concern is to minimize the number of clock cycle per instruction.
8. An OS specific to a given hardware platform.
9. An optical disk that was designed by the music industry in the 1980s.
10. It is the heart of the OS services.
11. An I/O control method wherein CPU continually polls a control register associated with each I/O port.
12. A type of disk organized in much the same ways as hard disks, with addressable tracks and sectors.
14. A system wherein terminals were connected to systems that allowed access by multiple concurrent users.
17. A type of RAID that makes a copy of all the data saves on a disk.
