1. A ____ chip holds software that is used to start the ROM
computer.
2. A hybrid system is a combination of ____ systems. batch and interactive
3. A system with ____ divides programs into parts and virtual memory
keep them in secondary storage, bringing each part
into memory only as it is needed.
4. Each peripheral device has its own software, called a(n) device driver
____, which contains the detailed instructions required
to start that device, allocate it to a job, use the device
correctly, and deallocate it when it's appropriate.
5. In active multiprogramming, each program is allowed time slicing
to use only a preset amount of CPU time before it is
interrupted so another job can begin its execution. The
interrupted job resumes execution at some later time.
This idea is called ____.
6. Starting in the 1950s, to reduce the discrepancy in control unit
speed between the I/O and the CPU, an interface called
the ____ was placed between them to act as a buffer.
7. The efficiency of a batch system is measured in ____, throughput
which is the number of jobs completed in a given
amount of time.
8. The most common mechanism for implementing mul- interrupt
tiprogramming was the introduction of the ____ con-
cept, whereby the CPU was notified of events needing
operating systems services.

on the consequences of missing the deadline. A ____
real-time system risks total system failure if the pre-
dicted time deadline is missed.
11. ____ allows separate partitions of a single server to Virtualization
support different operating systems.
12. ____ is the practice of using Internet-connected re- Cloud computing
sources to perform processing, storage, or other op-
erations.
13. ____ is where the data and instructions of a computer Main memory
must reside to be processed.
14. ____ systems are used in time-critical environments Real-time
where reliability is key and data must be processed
within a strict time limit.
15. A disadvantage of segmented memory allocation is external fragmentation
____.
16. The four memory management techniques presented loaded into memory
in this chapter share the requirement that the entire
program being executed must be ____.
17. One approach to performing compaction is to do it percentage
when a certain ____ of memory becomes busy.
18. By compacting and relocating, the Memory Manag- overhead
er optimizes the use of memory and thus improves
