types of computers-names
supercomputers, mainframe computers, midrange computers or minicomputers,
microcomputers, desktop PC, thin-client systems, laptop and notebook
supercomputer
fastest available at any given time, high cost, generally used in large organizations or
with demanding tasks and large datasets, military and scientific research
mainframe computers
high end of performance and reliability scales, today's performance at teraflop speeds
can handle millions of transactions per day
midrange computers or minicomputers
larger midrange computers are relatively small, inexpensive, and compact computers,
perform same functions as mainframe but to more limited extent
microcomputers
personal computers (PCs), smallest and least expensive of general purpose computers
desktop PC
familiar microcomputer system, has become standard tool for business and home,
generally includes a CPU and a separate, connected monitor and keyboard
thin-client systems
less powerful and fewer function desktop computer systems which do not have software
installed on them; when a user runs an application, it is accessed over a network from a
server instead of from a local disk drive
, laptop and notebook
smaller, easily movable, lightweight microcomputer that can be comfortably placed in a
briefcase; light, power efficient, and portable; typically designed to be optimized for use
with Internet-related applications such as Web browsing and e-mail
information system
input/input devices-> process/processor-> output/output devices
(media and touch a, b and c)linear presentation
central processing unit
brain of computer, most important element
storage/basic definition
what the computer "stores" or needs to remember to execute a program, works with
CPU
storage/secondary
Storage that is remote to the CPU and permanently holds data, even when the PC is
turned off, such as a hard drive
communication devices
makes it connected to other devices
input devices
keyboard, mouse, etc.
