The pre-computing age device which made use of beads and frames is?

The device that made use of beads and frames is called an Abacus. An abacus is a simple counting tool that consists of a wooden frame with parallel rods or wires running along its length. Beads or stones are strung on these rods or wires, and they can be moved back and forth to perform calculations. Abacuses were used in many ancient cultures, including China, Japan, and Egypt, and they are still used in some parts of the world today. They were particularly useful for merchants and traders who needed to perform quick calculations, and they were also used by scholars to teach mathematical concepts. To use an abacus, you move the beads along the rods to represent numbers. For example, if you wanted to represent the number 23, you would move two beads on the top row and three beads on the bottom row. You can then add, subtract, multiply, and divide by moving the beads in different ways. Overall, the abacus was a simple but effective device that played an important role in the development of mathematics and computing.
