WGU C952 STUDY GUIDE TEST PAPER
QUESTIONS AND CORRECT ANSWERS
TESTED PREP MATERIAL
●● Server
Answer: A computer used for running larger programs for multiple
users, often simultaneously, and typically accessed only via a network
●● Supercomputer
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
Answer: A computer inside another device used for running one
predetermined application or collection of software.
●● Personal mobile devices(PMDs)
Answer: Are 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 tables
●● Cloud computing
,Answer: refers to 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 (SaaS)
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
●● Acronym
Answer: A word constructed by taking the initial letters of a string of
words. For example: RAM is an acronym for Random Access Memory,
and CPU is an acronym for Central Processing Unit
●● Terabyte(TB)
Answer: Originally 1,099,511,627,776(2^40) bytes, although
communications and secondary storage systems developers started using
the term to mean 1,000,000,000,000(10^12) bytes. To reduce confusion,
we now use the term
●● tebibyte(TiB)
Answer: for 2^40 bytes
●● Moore's Law
,Answer: States that integrated circuit resources double every 18-24
months
●● Abstraction to Simplify Design
Answer: Used to characterize the design at different levels of
representation; lower-level details are hidden to offer a simpler model at
higher levels
●● Common Case Fast
Answer: Will tend to enhance performance better than optimizing the
rare case.
●● Performance via parallelism
Answer: Since the dawn of computing, computer architects have offered
designs that get more performance by computer operations in parallel
●● Pipelining
Answer: Moves multiple operations through hardware units that each do
a piece of an operation, akin to water flowing through a pipeline
●● Prediction
Answer: In some cases it can be faster on average to guess the start
working rather than wait until you know for sure, assuming that the
, mechanism to recover from a misprediction is not too expensive and
your prediction is relatively accurate.
●● Hierarchy of Memories
Answer: This is used to address conflicting demands of fast, large, and
cheap memory with the fastest, smallest, and most expensive memory
per bit at the top of the hierarchy and the slowest, largest, and cheapest
per bit at the bottom.
●● Dependability via Redundancy
Answer: We make systems Dependable by including redundant
components that can take over when a failure occurs.
●● System Software
Answer: Software that provides services that are commonly useful,
including operating systems, compilers, loaders, and assemblers
●● Operating system
Answer: Supervising program that manages the resources of a computer
for the benefit of the programs that run on that computer
●● Compiler
Answer: A program that translates high-level language statements into
assembly language statements
