The development of the transistor in the mid-20th century ignited a revolution in electronics and modern computing.

By replacing bulky and unreliable vacuum tubes, these miniature components allowed for the creation of portable devices.

Modern society now relies on this foundation for everything from medical diagnostics to global communication networks.

This shift facilitated the miniaturization of hardware, leading to the birth of personal computers and mobile telephony.

As transistors became increasingly dense on silicon chips, processing power followed an exponential growth trajectory.
