WGU C952 Computer Architecture Exam 313
Questions with Verified Answers
A computer designed for use by an individual, usually incorporating a graphics
display, a keyboard, and a mouse. - CORRECT ANSWER Personal computer (PC)
A computer used for running larger programs for multiple users, often
simultaneously, and typically accessed only via a network. - CORRECT ANSWER
Server
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. - CORRECT
ANSWER Supercomputer:
A computer inside another device used for running one predetermined
application or collection of software. - CORRECT ANSWER Embedded computer:
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 tablets. - CORRECT ANSWER Personal mobile devices (PMDs)
refers to large collections of servers that provide services over the Internet; some
providers rent dynamically varying numbers of servers as a utility. - CORRECT
ANSWER Cloud computing
,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. - CORRECT ANSWER Software as a Service (SaaS)
A microprocessor containing multiple processors ("cores") in a single integrated
circuit. - CORRECT ANSWER Multicore microprocessor
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. - CORRECT ANSWER Acronym
Originally 1,099,511,627,776 (240) bytes, although communications and
secondary storage systems developers started using the term to mean
1,000,000,000,000 (1012) bytes. To reduce confusion, we now use the term
tebibyte (TiB) for 240 bytes, defining terabyte (TB) to mean 1012 bytes. The figure
below shows the full range of decimal and binary values and names. - CORRECT
ANSWER Terabyte (TB):
Software that provides services that are commonly useful, including operating
systems, compilers, loaders, and assemblers. - CORRECT ANSWER Systems
software:
Supervising program that manages the resources of a computer for the benefit of
the programs that run on that computer. - CORRECT ANSWER Operating system
A program that translates high-level language statements into assembly language
statements. - CORRECT ANSWER Compiler
,Also called a bit. One of the two numbers in base 2 (0 or 1) that are the
components of information. - CORRECT ANSWER Binary digit
A command that computer hardware understands and obeys - CORRECT ANSWER
Instruction
A program that translates a symbolic version of instructions into the binary
version. - CORRECT ANSWER Assembler
A symbolic representation of machine instructions. - CORRECT ANSWER Assembly
language
A binary representation of machine instructions - CORRECT ANSWER Machine
language
A portable language such as C, C++, Java, or Visual Basic that is composed of
words and algebraic notation that can be translated by a compiler into assembly
language. - CORRECT ANSWER High-level programming language
A mechanism through which the computer is fed information, such as a keyboard.
- CORRECT ANSWER Input device
A mechanism that conveys the result of a computation to a user, such as a display,
or to another computer - CORRECT ANSWER Output device
, A display technology using a thin layer of liquid polymers that can be used to
transmit or block light according to whether a charge is applied. - CORRECT
ANSWER Liquid crystal display:
A liquid crystal display using a transistor to control the transmission of light at
each individual pixel. - CORRECT ANSWER Active matrix display
The smallest individual picture element. Screens are composed of hundreds of
thousands to millions of pixels, organized in a matrix. - CORRECT ANSWER Pixel
Also called a chip. A device combining dozens to millions of transistors. - CORRECT
ANSWER Integrated circuit
Also called processor. The active part of the computer, which contains the
datapath and control and which adds numbers, tests numbers, signals I/O devices
to activate, and so on. - CORRECT ANSWER Central processor unit (CPU)
The component of the processor that performs arithmetic operations. - CORRECT
ANSWER Datapath
The component of the processor that commands the datapath, memory, and I/O
devices according to the instructions of the program. - CORRECT ANSWER Control
The storage area in which programs are kept when they are running and that
contains the data needed by the running programs. - CORRECT ANSWER Memory
