Study Notes
History of Computing Devices
- Humans have used tools for computations and calculations since ancient times.
- Primitive devices like fingers, stones, and sticks were used for counting and keeping track of livestock.
Early Computing Devices
- The first computing devices were mechanical, not electronic, and did not have plugs, circuits, memory, or use electricity.
- Their primary function was to assist humans with simple arithmetic.
Abacus
- An abacus is a frame with rods and beads that can be moved for counting purposes.
- The exact history of the abacus is unknown, but it was used by the Babylonian, Chinese, Japanese, and Russian civilizations.
- Each row on the abacus represents a power of ten with ten beads on each row.
- The abacus had the following rows: tens, hundreds, thousands, 10 thousands, 100 thousands, millions, 10 millions, 100 millions, billions, and ones.
Leonardo da Vinci's Calculating Device
- Leonardo da Vinci designed a calculating device to perform basic arithmetic in approximately 1500 A.D.
- The device operated with wheels and pulleys.
- Da Vinci's sketches were complete and correct enough for modern engineers to build a calculator based on them.
Napier's Bones
- John Napier created a device called "Napier's Bones" or "Napier's Rods" in 1614.
- The device used rods to perform multiplication of any number by a number 2 through 9.
- For example, it could be used to calculate 7 x 846.
