Unit 4 - Animation, Simulation, & Modeling Test Questions and
Answers Rated A
accumulator - -a special register in the
CPU where data is put in order to peform
arithmetic and logic operations.
ALU - -the part of the CPU that performs
all logic and arithmetic operations.
assembly language - -low-level language
that uses symbolic names, rather than binary
sequences of 0s and 1s, to represent the
machine language instructions.
Cookies - -Small files or bits of data that
are stored on your computer.
CPU - -the part of the computer's hardware
that interprets and runs the computer program.
Data Privacy - -assures that personal
information (and sometimes corporate
confidential information as well) are collected,
processed (used), protected and destroyed
legally and fairly
Data Security - -controls access to
personal information and protects against its
unauthorized use and acquisition
Data Storage - -This is how you archive
your data. The two types of storage are hard
data (RAM, Hard Drive, flash drives, solid state)
and remote data (cloud computing)
deterministic - -Completely predictable, an
example would be a PRNG.
fair coin - -when flipped would come up
heads 50% of the time over a large number of
coin flips.
fetch-execute cycle - -the basic process
performed by the CPU. On each cycle the CPU
fetches the next instruction from RAM, interprets
it and executes it.
hypothesis - -an explanation that can be
tested by experimentation.
instruction counter - -a special register in
the CPU that keeps track of the next instruction
to be fetched.
instruction register - -a special memory
location in the CPU that stores the current
instruction that is being executed.
machine langauge - -a programming
language that is directly readable by the
computer's CPU. It consists entirely of 0s and 1s.
mod operator - -gives the remainder when
one number is divided by another.
model - -an abstraction that provides a
simplified representation of some complex object
or phenomenon.
modular arithmetic - -a system of arithmetic
for whole numbers where the numbers 'wrap
around' upon reaching a certain value known as
the modulus. An example would be clock
