Three principles characteristic of computer
Earliest Computer
Tally Sticks - It is used to record and document numbers, quantities, or even messages.
Abacus - To perform mathematical calculations, they used abacus which is a mechanical device used to aid an individual.
Napier’s Bones - Operations are performed by moving the rods around and placing them in specially constructed boards.
Slide Rule - They help to perform multiplication, division, roots, logarithms and trigonometry.
Pascaline - It is restricted to addition and subtraction.
Stepped Reckoner - It which can automatically add, subtract, multiply and divide.
Jacquard Loom - Created by an automatic loom controlled by punched cards.
Arithmometer - It could perform the four basic mathematic functions.
Difference Engine and Analytical Engine
Scheutzian Calculation Engine - This is the first printing calculator.
Tabulating Machine - This is to help on summarizing information and accounting.
Havard Mark 1 - Which is known as IBM Automatic Sequence Controlled Calculator (ASCC).
Z1 - input is via punch tape into inserted into a punch tape reader and all output was generated through punch tape.
Atanasoff-berry computer(abc) - it was the first electronic digital computing device.
Eniac - it was the first electronic general-purpose computer.
Univac 1 - it was the first commercial computer.
Edvac - it has memory to hold both a stored program as well as data.
The first portable computer - osborne 1
