The first computers, developed in the mid-20th century, were large, room-sized machines that used vacuum tubes for circuitry and magnetic drums for memory. They operated on binary code and required complex programming, often using punched cards or paper tape for input. These early systems, like the ENIAC and UNIVAC, were primarily used for scientific calculations and data processing, lacking the user-friendly interfaces we have today. Their immense size and power consumption limited their accessibility and use, making them primarily tools for government and research institutions.
