Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers.
The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information.
Peripheral devices include input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (e.g., the 2000s-era touchscreen).
Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved.
The earliest counting device was probably a form of tally stick.
Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres, cones, etc.) which represented counts of items, probably livestock or grains, sealed in hollow unbaked clay containers.
