Study Notes

Computer Generations

  • First Generation (1940-1956): Used vacuum tubes. Computers relied on machine language. Single-tasking, meaning they could only solve one problem at a time. Input via punch cards, output via printouts. Examples include UNIVAC-1 and ENIAC. Large, bulky, and required significant cooling due to heat produced. Consummed high amounts of power.

Second Generation (1956-1963)

  • Used transistors instead of vacuum tubes, making them more powerful, reliable, less expensive, smaller, and cooler.
  • Used magnetic tape for secondary storage.
  • Saw the emergence of high-level programming languages (FORTRAN, COBOL, ALGOL, SNOBOL) and batch operating systems.
  • More powerful than first-generation computers (more than ten times faster).
  • Smaller size, needed less space.
  • Consumed less power.
  • High-level programming languages made writing programs easier.

Third Generation (1963-1975)

  • Integrated circuits (ICs) were the hallmark, which combined many electronic components (transistors, resistors, capacitors) onto a single silicon chip.
  • Decreased need for wiring.
  • ICs made the computers smaller, less expensive, reliable, and faster.
  • Dissipated less heat, consumed less power.
  • Construction of larger magnetic based random access memory.
  • Development of minicomputers.
  • Parallel advancements in storage facilitated larger capacity magnetic disks.
  • Standardization of high-level programming languages.
  • Users interact with computers through keyboards, monitors, and operating systems.

Fourth Generation (1975-1989)

  • Introduction of the microprocessor, which integrated all the circuits required for arithmetic, logic and control onto a single chip.
  • The average number of electronic components on a silicon chip doubled each year after 1965.
  • Increased capacity of random access memories (RAM) with faster access times.
  • Hard disks became cheaper, smaller, and larger in capacity.
  • Popularity of floppy disks as a portable storage medium.
  • Development of high-speed networking, enabling multiple computers to communicate and share data.
  • Increased use in business, industry, and commercial applications; use in scientific and engineering analysis.
  • Development of several new operating systems (MS DOS, MS Windows, Apple's OS).

Fifth Generation (1989-Present)

  • Design emphasis is on artificial intelligence (AI), robotics, natural language processing, expert systems and online social networks.
  • Continued rapid miniaturization of components and dramatic increase in the power of microprocessor chips.
  • Increased capacity for main memory and hard disk storage.
  • VLSI and ULSI (Ultra Large Scale Integration) technologies brought very powerful desktop PCs, workstations and powerful servers,.
  • Growth of computer networks, including internet.
  • Availability of portable computers (laptops).
  • More user-friendly interfaces with multimedia features make systems easier to use.
