The document summarizes different types of computers based on their size and capabilities. It discusses super computers as the largest and most powerful computers used for specialized tasks like weather forecasting. Mainframe computers are described as the second largest and most capable, supporting up to 100 users. Mini computers are depicted as mid-sized with less power than mainframes. Micro computers are introduced as the smallest digital computers, including desktops, laptops, palmtops, wearables, and pocket computers designed for single user mobility. Examples are provided for each type.

2. Super Computers
 Largest and powerful computer
 Capable of processing large amount of data at a
tremendous speed.
 Expensive and used only for specialized purpose.
 Used for weather forecasting, weapon research,
designing vehicles, aircrafts etc.
 For Example:: CRAY, PLEIADES, PARAM PADMA,
IBM ROAD RUNNER, TIANHE-IA, NEC EARTH
SIMULATOR, CRAY JAGUAR, IBM BLUE GENE,
STRATUS etc…..

Deep Blue was a chess-playing
computer developed by IBM. On May 11,
1997, this machine won the six-game match
against world champion Garry Kasparov by
two wins to one with three draws. Kasparov
accused IBM of cheating and demanded a
rematch. IBM refused and retired Deep Blue.
Kasparov had beaten a previous version of
Deep Blue in 1996.

9. Mainframe Computer
 Also known as BIG IRON
 Second largest, expensive and ultra fast computers
 Capable of processing millions of data at extremely
high speed and also has massive storage capacity
 Supports upto 100 users at a time
 Used in large organization, financial data processing,
universities etc
 For EXAMPLES::
