Study Notes
Characteristics of First Generation Computers
- Utilized vacuum tubes as the primary electronic component, enabling basic computational functions.
- Employed magnetic drums and magnetic tapes as main memory storage solutions, allowing data retention and retrieval.
- Utilized machine language for programming, making it challenging to use and understand for many users.
- Required significant electricity consumption, leading to excessive heat generation and necessitating cooling systems.
- Notorious for being large in size, often occupying entire rooms, limiting accessibility and deployment.
- Input and output managed through punched cards and paper tape, which were cumbersome compared to modern methods.
- Notable examples include ENIAC, UNIVAC I, IBM 650, and IBM 701, representing key advancements in early computing.
- Approximately 100 different vacuum tube computers were produced from 1942 to 1963, marking a period of rapid technological experimentation and development.
Third Generation of Computers (1960s-1970s)
- Integrated circuits (ICs) became the primary electronic component, enhancing performance and efficiency.
- Utilized large magnetic core memory along with magnetic tape and disk for data storage.
- Supported high-level programming languages such as FORTRAN, BASIC, Pascal, COBOL, and C, allowing for more sophisticated programming.
- Known as minicomputers, they were smaller, cheaper, and more efficient compared to second generation computers.
- Offered significant improvements in speed and reliability over previous generations.
- Common input/output devices included magnetic tape, keyboards, monitors, and printers.
- Notable examples include IBM 360, IBM 370, PDP-11, and UNIVAC 1108.
Fourth Generation of Computers (1970s-present)
- Very Large Scale Integration (VLSI) and microprocessors are the main electronic components, featuring thousands of transistors on a single microchip.
- Employed semiconductor memory technologies such as RAM and ROM for data storage.
- RAM (volatile) temporarily stores programs and data; contents are lost when power is turned off.
- ROM (non-volatile) permanently stores programs and data; contents are retained even when the computer is powered off.
- Continued the trend of using high-level programming languages, now including Python, C#, Java, JavaScript, Rust, and Kotlin.
- Smaller, cheaper, and more efficient compared to third generation computers, reflecting technological advancements.
- Enhanced speed, accuracy, and reliability over third generation devices.
- Input/output devices expanded to include keyboards, pointing devices, optical scanners, monitors, and printers.
- Networks emerged, allowing for linkage of two or more computer systems.
- Noteworthy examples include IBM PC, STAR 1000, APPLE II, and Apple Macintosh.
