First Generation Computer
Vacuum Tubes: These computers used large, fragile glass tubes for their circuitry, acting as switches or amplifiers in the CPU. Size and Weight: They were huge, filling entire rooms and floors of buildings, requiring extensive cooling due to the heat generated by vacuum tubes. Limited Memory and Power: Despite their size, they had very limited memory and processing power, measured in kilobytes or less. Input/Output: Data input and output were done using punch cards and paper tape, with results often printed on paper.
Examples: ENIAC UNIVAC I IBM 701
Reliability Issues: Vacuum tubes were prone to failure, leading to frequent breakdowns and maintenance problems. High Cost: These computers were expensive to build and maintain, mainly used by governments, large corporations, and research institutions.
