summarized description about type of computer

2. The most powerful computers in terms of performance
and data processing are the supercomputers.
In 1964, Seymour cray designed the first super
computer “CDC 6600”.
These are specialized and task specific computers used
by large organizations, like for research purpose,
Weather Forecasting, Nuclear weapons testing
Space Exploration.

3. IBM’s Mira in United States.
PARAM 8000 is considered India's first
supercomputer, now India's latest super computer is
PARAM YUVA II.

4. Although Mainframes are not as powerful as
supercomputers, but certainly they are quite expensive
computers capable of supporting hundreds, or even
thousands, of users simultaneously.
Many large corporations like banks,
insurance companies, travel and retail
sector, telecom companies process data on
a mainframe.
Examples - DEC,ICL,IBM3000 series.
IBM System z9

5. Minicomputers are also called as “Midrange
Computers”.
Design to support more than one user at a time .
These are generally used for processing large volume
of data in organizations.
For example, a production
department can use Mini-computers
for monitoring certain production
process.

6. These are the lowest end computer range in term of speed
and storage capacity
Ed Roberts built 1st micro computer in ‘1975’ the Altair
8800 (8-bit Intel 8080),which was produced by Micro
Instrumentation and Telemetry Systems (MITS). Other
examples- IBM PC , PC-AT .
Micro computers are the most common kind of computers
in use as of 2014 .
