According to historians what is the oldest device still used
It is unknown when exactly were developed first devices to facilitate calculation, such as the counting board, or abacus. The counting board was invented when someone grasped the idea of placing pebbles or other objects in columns marked on a flat surface, and assigning an order of units to the objects in each column.ater, loose objects in columns were replaced with beads that could slide along parallel rods. There is an unproved information, that similar to abacus device was used in Babylonia as early as 2400 BC. The word abacus itself is a Latin word, which comes from Greek άβακασ (board or table). The abacus was one of the earliest counting devices in Asia and parts of Europe. It is still used today for arithmetic: adding, subtracting, multiplying and dividing.

It is a good idea to think about the history of arithmetic, mathematics, writing and recorded information. The oldest surviving counting board is the Salamis tablet (originally thought to be a gaming board), used by the Babylonians circa 300 B.C., discovered in 1846 on the island of Salamis. It is a slab of white marble measuring 149cm in length, 75cm in width and 4.5cm thick, on which are 5 groups of markings.irca 1600 C.E., use and evolution of the Chinese 1/5 abacus was begun by the Japanese via Korea. In Japanese, the abacus is called Soroban. The 1/4 abacus, a style preferred and still manufactured in Japan today, appeared circa 1930. Later, loose objects in columns were replaced with beads that could slide along parallel rods.

Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality.he history of computer development is often in reference to the different generations of computing devices. Each of the five generations of computers is characterized by a major technological development that fundamentally changed the way computers operate. 1 From your device's apps menu, open Google Settings app or the Settings menu. 2  Touch for the account you want to change. 3  Turn Location History on or off for your account or devices: 4  Google Account: Move the top switch to turn Location History on or off for all devices associated with your Google Account.urn Location History on or off using Activity controls. 1  Go to the Activity controls section of My Account. 2  If prompted, sign in to the Google Account you want associated with your location. 3  Under Places you go, use the switch to turn Location History on or off.

Actually the Romans applied the word abacus (and also the word calculi, which comes from calculus (stone, pebble) to various objects, all with the common characteristic of having a flat surface: tables used in different kinds of games, sideboards and the calculating device still known as the abacus.ater, loose objects in columns were replaced with beads that could slide along parallel rods.
