1. Lesson 1.4 of Introduction to
Information and Communication
Technology
2. Computers may be classified into three
categories namely:
(1) According to purpose – their goals
and aims for a variety of tasks
(2) According to types of processing –
their special uses in different fields of work,
and
(3) According to capacity – with their
ability to perform a task, as well as the
maximum number of programs they
3. 1. General Purpose - handle variety
of tasks, versatile, less efficient, examples
are personal computer, PDA
2. Special Purpose - dedicated to a
specific task, more efficient because of
specialized programs, Faster processing,
examples are play station, word processor
7. 2. Digital - Machines that specialize in
counting, Use discrete numbers, result
obtained is precise and repeatable,
examples are digital clock, digital
thermometer, and calculator
8.
9. 3. Hybrid - Machines that incorporate
measuring capabilities of the analog
devices and the counting capability of the
digital devices, examples are Ana-Digi
watches (watches with both analog and
digital capabilities)
12. also known as Personal computer
used in homes, offices; for individual and corporate
uses
single users, Usually stand-alone to other computers
but generally used to carry out processing for a single
user
price ranges from 25,000.00 – 250,000.00
speed of processor is 5 – 20 MIPS
storage capacity is 32 Mb – 256 Mb of primary storage
No unusual power required for environment
considerations; may fit on top of a table or desk
examples are desktop, notebook, laptop, palmtop,
personal digital assistant (PDA), information
appliances, network computers, technical workstations
13.
14. midrange computer
For use by companies needing storage and
processing requirements, for more computer power
Multiple users, less than 100 users
price ranges from 250,000 – 10 Million
speed of processor is 25 – 100 MIPS
storage capacity is 32 Mb – 512 Mb of primary
storage
Requires controlled environment; Occupies own floor
space, like the size of a file cabinet
examples are Network servers, web servers, multiple
use systems
15.
16. large scale computer
for medium to large size business; Used by business and
government to provide centralized storage processing and
management of data of large amount
Multiple users greater than or equal to 100 users
price ranges from 10 Million – 50 Million
speed of processor is 440 – 4,500 MIPS; May have several
processors
storage capacity is 50 Mb – several gigabytes of primary
storage
Requires controlled environment; Requires full time operators;
Housed in a cabinet where peripherals are in separate
cabinets
examples are Enterprise systems, transaction processors,
super server
18. Used to compute intensive tasks
Designed for large-scale complex and scientific applications
Multiple users
price ranges from 10 Million – 2.5 Billion
speed of processor is 4 – 10 times faster than mainframes,
Several processors, 60 Billion – 3 Trillion MIPS, Fastest, most
processing power
storage capacity is 8,000 Mb+ +
Requires controlled environment; Space needed may be the
size of a car
examples are Scalable servers, Cray Computer, IBM Deep
Blue Super Computer
22. are microcomputers
whose case sits as a
“tower,” often on the
floor beside a desk,
thus freeing up desk
surface space.
23. also called laptop
computers , are
lightweight portable
computers with built-
in monitor, keyboard,
hard-disk drive,
CD/DVD drive,
battery, and AC
adapter that can be
plugged into an
electrical outlet; they
weigh anywhere from
1.8 to 9 pounds.
25. Smaller than
notebook computers
but larger and more
powerful than PDAs,
mobile internet
devices (MIDs) are for
consumers and
business
professionals.
Examples:
Smartphones and tablet
PCs
