4. ANALOG COMPUTER
This type of computer represents number by a physical quantity that is they
assign numeric values by physically measuring some actual property, such as the
length of an object, an angle created by two lines or the amount of voltage
passing through a point in an electric circuit.
Analog computer derive all their data from some of measurement.
Though effective for some applications this method of representing number is a
limitations of the analog computer.
The accuracy of the data used in an analog computer is directly related to the
precision of its measurement
5. DIGITAL COMPUTER
Hybrid computer combine the most desirable feature of
both analog and digital computer.
They have the speed of analog computer and the accuracy
of digital computer.
They usually used the special problems in which input data
derived from measurements is converted in to digits and
processed by computers.
6. HYBRID COMPUTER
Hybrid computer combine the most desirable feature of
both analog and digital computer.
They have the speed of Analog Computer and the accuracy
of Digital Computer.
They usually used the special problems in which input
data derived from measurements is converted in to digits and
processed by computers.
7. ON THE BASIS OF GENERAL
PURPOSE DIGITAL COMPUTER
ARE CLASSIFIED AS
Main frame Computer
Mini Computer
Micro Computer
Super Computer
8. MAIN FRAME COMPUTER
Faster than mini computer and have larger memory used in CPU intensive or
I/O intensive job, like .
in scientific and business applications and to process high volume of data in
large business applications..
Example-ibm-370 and ibm-s/390, dec vax-8800, cpc-7600, univac-111
9. MINI COMPUTER
Relatively faster and low cost compared to mainframes, higher than
pcs.
Design for real time dedicated multi user applications.
Example-ibm-17, hp-3000 decpdp-11
10. MICRO COMPUTER
Slow, cheap significant computing power.
Use of intel chips. Single processor system which can
supports the simple tasks like WP,ESS,DBMS etc
Example-ps 386, 486 PENTIUM (P-1, 2 ,3, 4]
11. SUPER COMPUTER
Large in size and large memory compared to all other computers.
Ideal for high end computing applications involving large volume of data and intensive
computing useintel chips.
These computers are design for ultra high performance tasks such as encryption, cracking,
creation of animation and for designing all knowledge based systems.
Example- ibms deep blue, cdc cyber family and cray x-mp/26
