Computer Generations Quiz

Five Generations of Computers

• The first generation of computers (1940-1956) used vacuum tubes for circuitry and magnetic drums for main memory, taking up entire rooms, were expensive to operate, and generated a lot of heat leading to malfunctions.
• Maximum internal storage capacity of first generation computers was 20,000 characters.
• First generation computers relied on machine language, the lowest level programming language, and could only solve one problem at a time.
• Input was based on punched cards and paper tape, and output was displayed on printouts.
• Examples of first generation computer technology include Univac and DNA computers invented by J. Presper Eckert.

Second Generation

• The second generation of computers (1956-1963) replaced vacuum tubes with transistors, allowing computers to become smaller, faster, cheaper, more energy efficient, and more reliable.
• Hardware advances included magnetic core memory, magnetic tape, and magnetic disc.
• Transistors still generated a great deal of heat, but were a vast improvement over vacuum tubes.
• Second generation computers still relied on punched cards for input and printouts for output.

Third Generation

• The third generation of computers (1964-1971) was marked by the development of integrated circuits, miniaturizing transistors and placing them on silicon chips.
• This led to increased speed and efficiency, and allowed users to interact with computers through keyboards and monitors, and interface with an operating system.
• Computers became accessible to a mass audience due to their smaller size and lower cost.

Fourth Generation

• The fourth generation of computers (1971-1984) was marked by the development of microprocessors, integrating thousands of integrated circuits onto a single silicon chip.
• The Intel 4004 chip (1971) integrated all computer components, and IBM introduced its first personal computer in 1981.
• Microprocessors led to the development of GUIs, the mouse, handheld technology, and networks, eventually leading to the internet.

Fifth Generation

• The fifth generation of computers (present and beyond) is based on artificial intelligence and is still in development.
• Current applications include voice recognition, and the use of parallel processing and superconductors is helping to make artificial intelligence a reality.
• Future developments include quantum computation, molecular and nano technology, and the goal of developing devices that can respond to natural language input and learn and self-organize.
