- The Early Days: Mainframes and Minicomputers
The journey of computers began in the mid-20th century with the development of mainframe computers. These Computers have transformed dramatically since their inception, evolving from large, room-sized massive machines, such as the IBM 7094, were primarily used by large organizations for complex calculations. The 1960s saw the introduction of minicomputers, which were smaller and more affordable, making computing accessible to universities and smaller businesses.
Key Features:
- Size and Cost: Mainframes were prohibitively expensive and required dedicated facilities. Minicomputers, while still costly, opened the door for wider use.
- Functionality: Early computers were primarily used for scientific calculations and data processing.
The Personal Computer Revolution
The 1970s and 1980s marked a significant shift with the emergence of personal computers (PCs).
