Study Notes

First Generation Computers

Characterized by vacuum tube technology, which was heavy, inefficient, and costly to operate.
Lacked versatility, speed, and reliability; prone to frequent hardware failures requiring constant maintenance.
Used machine language, making programming challenging and cumbersome; manual assembly of components was necessary.
Overall commercial appeal was poor due to high operational costs and operational difficulties.

Second Generation Computers (1956 to 1963)

Transitioned from vacuum tubes to transistors, resulting in smaller, faster, cheaper, and more energy-efficient machines.
Transistors made from semiconductor materials, such as germanium and silicon, allowing for electrical function amplification with lower power consumption.
Employed magnetic cores for primary memory and magnetic disks for secondary storage, but still relied on punched cards for input/output.
Major programming advancement from machine language to assembly language, utilizing abbreviations like ADD and MULT, simplifying coding processes.
Emergence of early high-level programming languages such as COBOL and FORTRAN.
Examples include PDP-8, IBM 1401, and IBM 7090.

Characteristics of Second Generation Computers

Smaller in size compared to first-generation computers.
Reduced computational time from milliseconds to microseconds.
Enhanced reliability with less frequent hardware failure and maintenance.
Portable with lower heat generation, though air conditioning was still required.
Manual assembly of individual components was still necessary for functioning units.

Third Generation Computers (1964 to Early 1970s)

Introduced integrated circuits (ICs), revolutionizing computer design with multiple components on a single silicon chip.
Resulted in even smaller and more efficient computers, decreasing reliance on individually wired transistors.
Microcomputers emerged, including desktops, laptops, and PDAs, making computing more accessible and affordable for personal and small business use.
Notable PC manufacturers include APPLE, IBM, Dell, and Hewlett-Packard.

Microcomputers

Desktop Computers (PCs): Primarily used for standalone purposes, consisting of a system unit, display, keyboard, and storage with affordable pricing appealing to individuals and small businesses.
Laptops: Portable computers akin to notebooks, lightweight, and equipped with rechargeable batteries, allowing use anywhere. Generally more expensive than desktops.

Minicomputers

Introduced in the early 1960s by Digital Equipment Corporation (DEC) with the PDP series, termed as minicomputers.
Capable of processing and storing more data than microcomputers and faster than minicomputers.
Mainframes, larger than minicomputers, can execute multiple programs simultaneously and are suitable for large businesses and scientific applications.

Mainframe Computers

Feature large storage capacity for centralized data access and processing, often used in large organizations.
Notable examples include IBM’s ES000, VAX 8000, and CDC 6600.

Supercomputers

Designed for optimizing floating point operations per second (FLOPS), considered superior if above one gigaflop.
Highest processing speed for scientific and engineering problems, operating with multiple CPUs in parallel.
Processing speeds generally range from 400 to 10,000 MFLOPS.
