QUESTIONS AND ANSWERS SURE A+
✔✔FALSE - ✔✔A personal digital assistant is a laptop computer that emphasizes small
size, reduced weight, low cost, and wireless networking and is capable of performing
only light-duty tasks, such as web browsing, e-mailing, and word processing.
✔✔TRUE - ✔✔Some experimental computers have used quantum physics to perform
data storage and computation.
✔✔TRUE - ✔✔Windows OSs tend toward an all-inclusing approach to system software,
bundling most system software functions in the OS.
✔✔TRUE - ✔✔The evolution of Microsoft OSs is a good example of how software
development depends on hardware technology.
✔✔algorithm - ✔✔A(n) ______ is a program in which different sets of instructions are
applied to different data input values.
✔✔doubly linked list - ✔✔An element in a(n) ______ contains pointers to both the next
and previous list elements.
, ✔✔Floating-point - ✔✔_____ notation encodes a real number as a mantissa multiplied
by a power (exponent) of 2.
✔✔long integer (double-precision) - ✔✔A(n) _____ is an integer stored in double the
normal number of bit positions.
✔✔numeric range - ✔✔Increasing a numeric representation format s size (number of
bits) increases the _____ of values that can be represented.
✔✔hexadecimal - ✔✔Assembly (machine) language programs for most computers use
_____ notation to represent memory address values.
✔✔data structure - ✔✔A(n) _____ is a data item composed of multiple primitive data
items.

representing whole number quantities from digits representing fractional quantities.
✔✔string - ✔✔A(n) _____ is an array of characters.
✔✔segmented memory model - ✔✔Most Intel CPUs use the _____, in which each
memory address is represented by two integers.

integers might result in overflow but never ___ or _____ .
✔✔array - ✔✔"A(n) _____ is a sequence of primitive data elements stored in sequential
storage locations."
✔✔record - ✔✔A(n) _____ is a data structure composed of other data structures or
primitive data elements, commonly used as a unit of input and output to and from files
or databases.
