Study Notes
Computer Generation
Definition: A computer generation refers to a period of time during which a particular type of computer technology is dominant.
Key Features of Each Generation:
First Generation (1940s-1950s)
- Vacuum Tubes: Used vacuum tubes as the primary electronic component
- Size and Cost: Large, expensive, and prone to overheating
- Programming: Machine language, using binary code
- Examples: ENIAC, UNIVAC I
Second Generation (1950s-1960s)
- Transistors: Replaced vacuum tubes with transistors, reducing size and increasing speed
- Programming: Assembly language, using symbolic codes
- Examples: IBM 1401, TX-0
Third Generation (1960s-1980s)
- Integrated Circuits: Introduced integrated circuits, further miniaturizing computers
- Programming: High-level languages, such as COBOL and FORTRAN
- Examples: IBM System/360, Apple I
Fourth Generation (1980s-2000s)
- Microprocessors: Introduced microprocessors, enabling personal computers
- Programming: Developed languages, such as C and Pascal
- Examples: IBM PC, Apple Macintosh
Fifth Generation (2000s-present)
- Artificial Intelligence: Focus on AI, machine learning, and natural language processing
- Programming: Developed languages, such as Python and Java
- Examples: Modern smartphones, cloud computing, and IoT devices
Learn about the key features of each computer generation, including vacuum tubes, transistors, and integrated circuits. Discover the evolution of computer technology from the 1940s to the present.
