Device which performs calculation

It is a typically a portable device which performs calculation ranging in complex mathematics to arithmetic.The modern electronic calculator is designed varied from credit card sized model to give away,cheap to desktop models which are connected to printers. They are with integrated circuits which have reduced the size and cost.They are using now a days everywhere and anywhere in the world.

Design and functioning:

The electronic calculators which are embedded with keyboards which have digits as button which can do arithmeticaloperation and has numbers may be larger or smaller in size. The normal calculator allows only one digit at a time and some advanced calculators have buttons which can function in a multifunctional way with the key setup combinations.

Display: A normal calculator has a liquid crystalline display they keys are designed large in the size to that it improves readability and decimal separator is uses instead of the fractions. Many types of symbols are embedded with functions and commands to make more completed calculationsto bedone. The complex calculations can also be performed in the calculator with the buttons having the functional ability.

Memory: Now a days the designs have come out with memory facility in which number and calculations can be stored. The basic calculator normally stores numbers one at a time and more specific designs store variables which carry the complex calculations.Some are designed to store on the computer also. The new designs have come up with array indexes which can store more memory.

Power source: The main power source of the calculator is solar cells, solar strips, batteries and some old models with main power sources.Usually, all the designs are provided with on and off button to save the power. Now a days the designs have come up with dual power source in which solar and batteries are provided if the batteries are exhausted one can continuously use it with solar power strips.

Internal workings: The components embedded in the design are power source, key pad, display panel and whole working runs with an integrated circuit which is the main functioning aspect of the design. Some more types have additional display unit with a printer attached which has printer roll in it and full-fledged printing mechanism is attached to the system. There is a process chip which is also present which is linked to the integrated circuit.

Summing up:

It is a typically a portable device which performs calculation ranging in complex mathematics to arithmetic. They are using now a days everywhere and anywhere in the world.
