what is mini computer

 A mini computer is also known a small size of computer. It is a category of small computer that was introduced into the planet within the mid-1960. A mini computer may be a computer which has all the features of an out sized size computer, but its size is smaller than those, A mini computer lies between the mainframe and therefore the micro computer because its size smaller than the previous one and bigger than the latter inner. A mini computer is additionally called as a mid-range computer. Mini computer are mainly multi-users systems where quite one user can work simultaneously. Mini computer Example: IBM's AS/400e, Honaeywell200, TI-990. 

    Mini computer can support multi-user at a time otherwise  you can say that mini computers may be a multiprocessing system. Also the facility  of processing of mini computer isn't larger than the facilty of main frame and supercomputers. These minicomputers can do time-sharing, execution, and online processing.

The size of mini computer can range from 12 inches in breadth to but 7. This small size is particularly attractive to students because they will use it use it any where they need.

History of Mini computer

    The term Mini computer was come to understand with in the 1960 and thru that point only the tiny computers are made by making the utilization of transistors and core memory technologies. the primary minicomputer which was developed was referred to as Digital Equipment Corporation, which was made by using transistors and it costs from the US $16000.

Types Of Mini Computer

     The types of mini computer are- tablet PC, Desktop Minicomputer, Cell Phones, Notebook, High-end mP3Players,etc.

Uses of Mini Computer

     Each person employing a Mini Computer has their on terminal attached by wires or via a modem to the pc proper. The minicomputer spends a touch little bit of time on one person's task, then jobs it thinks are most vital. If you're the sole one employing a mini computer, this will ne one fast machine.

    But once many user and many people are "on" the system, the thing begins to slow down-you may type something then await a moment or more before you see a response on the screen. Mini Computers want to be the sole option for companies. Now, many firms are turning to private computers to accomplish an equivalent thing faster and cheaper.

  They were used for 3 primary purposes :

 Process Control 

     Mini computer are primarily employed  by the business for the manufacturing control of the method. Process Control has two primary function- data acquisition and feedback.

Ex:- Factories make use of minicomputers to regulars the manufacturing process, If any problem appears in any a pat of the method, then it recognizes the change and made required adjustments. 

Data management 

     Mini computer that we use for the info management can do any task regarding data love it can taken restore or generate data.

Communication

     Mini computers act as an interface between the human operator and a bigger processor. the user can run operations. like error checking with the assistance of mini computer then can use the device for creating adjustment also.

The other uses are as following 

•  They're also used for scientific computations. 
• Used for business-transaction processing.
• Used for management.
• Used for file handling.
• Used for engineering Computations.

Characteristics of a mini Computer

• Its size is smaller than a mainframe or supercomputer.
• Its's less costly than mainframe or supercomputer.
• Its's less powerful than mainframe or supercomputer and more powerful than microcomputer and workstation.
• It can do several tasks directly.
• It are often employed by many of us at just one occasion.
• It's employed by many of us at at just one occasion.
• Its's employed by small enterprises.

Applications of minicomputer.

1. Minicomputer was utilized in business accounting.
2. A network or minicomputers are often created which allows an outsized library with its different two branches to create its own internal network and this network is more powerful than those handled by large-scale computer installation.
3. It's employed by the varied sub-department  of the businesses in order that they will unload the task of mainframe computer.
4. the areas where mini computers are traditionally applied in information handling are:

• Circulation
• Cataloguing
• Series control
• management
• Acquisition
• Communications
• information retravel

Advantages of mini Computer

• they are easy to use,
• They will fit anywhere.
• they're easy to hold.
• As compared to their size, they're fast.
• They hold a charge for an extended time.
• They didn't require a carefully controlled operational environment,
• They are more reliable.

Disadvantages of Mini Computer

• Some mini computers don't have USB port,
• Mini computer don't have any CD/DVD drive.
• The user might not be conversant in the OS.
• The Keyboard are often small for fast typists.
• During this, generally, there's not much storage on board.
• It are often too small to try to to certain projects.
