Structure
A pocket computer will have the following structure:
- A single microprocessor chip: To solve calculations and algorithms.
- Circuit board and rubber buttons: Used for data input and calculations. When you press a button on the keyboard, the control circuit under the rubber layer sends electrical pulses to the processor chip, which then sends back the signal on the computer screen.
- Computer monitors: Usually made of LED screens or vacuum diodes . Currently, some machines have liquid crystal screens or LCD screens , which are more energy-efficient.
- Battery: As the main power supply for pocket computers, can be primary batteries, solar batteries.
Working principle
Pocket calculators use integrated circuits and microprocessor chips to perform calculations. These circuits use transistors for basic to complex calculations. The more transistors a pocket calculator has, the more complex calculations it can perform.
When you enter information into the pocket calculator, the chip inside converts the information into its binary equivalent, which calculates and outputs the results on the screen.
