SHORT
ANSWER
57. The motherboard is the computer's main circuit
board and it houses all essential chips and provides connecting circuitry
between them.
58. Benchmarks are the results of tests that are
run to gauge the overall speed of a microprocessor, which can then be compared
to the results for other microprocessors.
59. Cache is special high-speed memory that allows
a microprocessor to access data more rapidly than from memory located elsewhere
on the motherboard.
60. The ROM BIOS tell the computer how to access
the hard disk, find the operating system, and load it into RAM; once the
operating system is loaded, the computer can understand your input, display
output, run software, and access your data.
61. Storage devices include floppy disk drives,
Zip drives, hard disk drives, tape drives, CD drives, and DVD drives.
62. A read-write head mechanism is in a disk drive
and is used to read and write the magnetized particles that represent data on a
disk.
63. If you run out of bays, you can purchase
standalone, external drives that sit outside of the computer case and are
connected to the computer by a cable.
64. If a read-write head runs into a dust particle
or some other contaminant on the disk, it might cause a head crash, which
damages some of the data on the disk.
65. Phase change technology is used by a CD-RW
drive and CD-RW disks to alter the crystal structure on the disk surface,
changing the structure from light to dark and back again many times, making it
possible to record and modify data much like on a hard disk.
66. An expansion port is any connector that passes
data in and out of a computer or peripheral device.
67. Software consists of computer programs,
support modules, and data modules that work together to provide a computer with
the instructions and data necessary for carrying out a specific type of task.
68. In word processing software, spelling is
checked by comparing the words in a document with the words in a dictionary
file of correctly spelled words; this dictionary file is a data module that is
supplied by the software, not by the user.
69. Some examples include the element's shape, its
color, its behavior, and where it appears on the screen.
70. An interpreter reads the first instruction in
a script, converts it into machine language, and then sends it to the
microprocessor. After the instruction is executed, the interpreter converts the
next instruction, and so on.
71. The processor is a resource, and RAM, storage
space, and peripherals are also resources.
72. Document production software assists you with
composing, editing, designing, printing, and electronically publishing
documents.
73. The three most popular types of document
production software are word processing, desktop publishing, and Web authoring.
74. Readability formulas are used to analyze the
reading level of your document, to find out if your writing matches your target
audience, based on sentence length and vocabulary.
75. Frame-oriented software allows you to divide
each page into several rectangular-shaped frames that you can fill with either
text or pictures; desktop publishing software tends to be frame-oriented.
76. A copyright is a form of legal protection that
grants the author of an original work an exclusive right to copy, sell,
distribute, and modify that work, except under special circumstances described
by copyright laws.
ESSAY
77. It is technically possible to upgrade your
computer's microprocessor, but computer owners rarely do so. One reason is the
cost. The price of the latest, greatest microprocessor can often get you more
than halfway to buying an entirely new computer system. Technical factors also
discourage upgrades. A microprocessor can operate at full efficiency only if
all of the components in the computer can also handle the faster speeds.
78. CRT technology uses gun-like mechanisms to
direct beams of electrons toward the screen and activate individual dots of
color that form an image; CRT monitors offer an inexpensive and dependable
computer display. An LCD produces an image by manipulating light within a layer
of liquid crystal cells.
79. Proper nouns and scientific, medical, and
technical words are likely to be flagged as misspelled, even if you spell them
correctly, because they do not appear in the spelling checker's dictionary.
Also, if a document contains the phrase "a pear of shoes," even
though you meant to use "pair" rather than "pear," the
spelling checker will not catch the mistake because "pear" is a valid
word in its dictionary. Furthermore, the spelling checker will not help if you
have trouble deciding whether to use "there" or "their,"
"it's" or "its," or "too" or "to."
80. Vertical market software is designed to
automate specialized tasks in a specific market or business. One example is
patient management and billing software that is specially designed for
hospitals. Horizontal market software, on the other hand, is generic software
that can be used by just about any kind of business. Payroll software,
accounting software, and project management software are examples of horizontal
market software.
