Computer word taken from word compute which is mean count and then calculate and after calculation based on certain decisions .
their are two type computer basis of application and size which are-
Basis of Application Type of Computer –
1-Analog
2-Digital
3-Hybrid
1-Analog Computer-
These type of computer is used to measure something else a A map is an analog of an area of land.
Computer that measure contains data-data that may change from minute to minute are
Analog computers. In actual life such computer are used only in laboratories of engineering and scientific institution.
2-Digital Computer –
This type of computer is used to using to measure and show Result in the case of a clock with hands which is an analog device the power of a spring or electricity is translated through series of gears.
These are the computer that we see in our daily all personal & home PC fall in this category.
3-Hybrid Computer-
This type computer is mixture of digital computer & hybrid computer. This type of computer is using in optical, arithmetic & biological computer these some most type of computer.
On the basis of size computer dived in to four type–
- Super Computer
- Main Frame Computer
- Mini Computer
- Super Computer
1-Super Computer-Very big computer, high speed, telecommunication facilities
As calculator with help the help of super computer we can million ,billion instruction in seconds. User of super computer 1 to 120 in one time. Name of super computer
CRAY XMP-14
Note:
Very high speed number of processor joined together to get the computing done very fast.
2-Main Frame Computer-
Main Frame computer approximately super computer because of its speed is too good its use r 1 to 50 in one time but it is less than super computer in size.
3-Mini Computer-
Mini computer is good because of its speed is too good its use r 1 to 15 in one time but it is less than super computer in size.7 to 8 printer online we can attach with to Mini computer .
Note:
In speed fast than micro computer & less than Main frame Computer.
4-Micro Computer-
Micro computer is small computer this is called home pc or personal computer 1 or two user can do work at one time only but its speed is too good but less than Mini Computer. Micro computer is consisting of micro processors.
