The history of computers began with mechanical devices such as the abacus, one of the oldest calculation tools ever invented. Later, the great mathematician Charles Babbage proposed the Analytical Engine, which is considered the first concept of a programmable computer. During this period, devices like the DE were introduced, laying the foundation for modern computing. These inventions marked the beginning of a journey from simple calculation tools to advanced electronic machines.
the CPU has evolved from vacuum tubes to modern microprocessors. The 1st generation used vacuum tubes, while the 2nd generation relied on transistors. By the 4th generation, computers became personal and affordable.
