Physical Address - correct answer Address in main memory
Page fault - correct answer event that occurs when accessed page is not present in
main memory
Virtual Address - correct answer address that corresponds to location in virtual space
and translated by address mapping to physical address when memory is accessed
Address translation - correct answer aka Address Mapping: process where virtual
address is mapped to address used to access memory
Segmentation - correct answer variable size address mapping scheme where address
consists of 2 parts: segment number and segment offset
Page table - correct answer table containing virtual to physical address translation in
virtual memory. stored in memory, indexed by virtual page number, table contains
physical page number for that virtual page if the page is currently in memory.
Swap space - correct answer space on disk reserved for full virtual memory space of
process
Virtually addressed cache - correct answer A cache that is accessed with a virtual
address rather than a physical address
Aliasing - correct answer situation where two addresses access the same object.
occurs in virtual memory when two virtual addresses for the same physical page
,Physically addressed cache - correct answer cache that is addressing by physical
address
Supervisor Mode - correct answer kernal mode: Mode indicating that a running
processing is an operating system process
- correct answer
Multithreading - correct answer Allows different parts of a single program to run
concurrently.
Blocking - correct answer a failure to retrieve information that is available in memory
even though you are trying to produce it
Direct Mapped cache - correct answer A cache structure in which each memory
location is mapped to exactly one location in the cache
Fully Associated cache - correct answer cache structure in which block can be placed
in any location in the cache
Set-Associated cache - correct answer cache that has fixed number of locations (at
least two) where each block can be placed
Throughput - correct answer also called bandwidth: measure of performance, number
of tasks completed per unit of time
RAID - correct answer Redundant Arrays of Inexpensive Disks
Block - correct answer or line: minimum unit of information that can be either present
or not present in cache
, Server - correct answer A computer used for running larger programs for multiple
users, often simultaneously, and typically accessed only via a network
Supercomputer - correct answer A class of computers with the highest performance
and cost; they are configured as servers and typically cost tens to hundreds of millions
of dollars
Embedded computer - correct answer A computer inside another device used for
running one predetermined application or collection of software
Personal mobile devices - correct answer small wireless devices to connect to the
Internet; they rely on batteries for power, and software is installed by downloading apps.
Conventional examples are smart phones and tablets
Cloud computing - correct answer large collections of servers that provide services
over the Internet; some providers rent dynamically varying numbers of servers as a
utility
Software as a Service - correct answer delivers software and data as a service over
the Internet, usually via a thin program such as a browser that runs on local client
devices, instead of binary code that must be installed, and runs wholly on that device.
Examples include web search and social networking
Multicore microprocessor - correct answer A microprocessor containing multiple
processors ("cores") in a single integrated circuit
Terabyte (TB) - correct answer 1 trillion bytes, 10^12
tebibyte (TiB) - correct answer 2^40 bytes
Systems software - correct answer Software that provides services that are commonly
useful, including operating systems, compilers, loaders, and assemblers
