Study Notes

History of Computing (Introduction)

Computing dates back to early human civilization
Early humans used fingers, toes, stones, and sticks as rudimentary calculating tools
Many African cultures, particularly West African countries, used cowrie shells for calculations
The Yoruba people of Nigeria developed a binary number system called "Odu Ifa" for divination and other purposes.
The abacus, developed in Asia between 2700 and 2300 BCE, is an early calculating tool.
John Napier developed logarithms in 1614 for easier calculations.
William Oughtred invented slide rules in 1632 based on Napier's work.
Blaise Pascal built the Pascaline, an early calculating machine, in 1642-1644, useful for addition and subtraction but limited for multiplication and division
Charles Xavier Thomas de Colmar created the arithmometer, an early mechanical calculator in 1820, capable of performing addition, subtraction, multiplication, and division.
Joseph Marie Jacquard developed the Jacquard loom in 1804, an early automated system.
Charles Babbage, a scientist, inventor, and mathematician, created the difference engine in the 1820s.
Lady Lovelace, a mathematician and author, an associate of Babbage, is credited as the first computer programmer and worked on the analytical engine in the 19th century.
Herman Hollerith, a statistician for the US Census Bureau in 1880, created the first electromechanical tabulating machine used in 1890.
John Atanasoff and Clifford Berry developed the Atanasoff-Berry Computer (ABC) in the late 1930s/early 1940s, an early electronic digital computer.

The First Generations of Computers (1940s – 1950s)

Computers emerged in the 1940s, and their first generation extended until the1950s.
The first generation computers were large and costly, using vacuum tubes for operation.
Primarily used for scientific and military purposes.
Computers were characterized by large size, high cost, limited performance and slow operation speed.
Early computers like the ENIAC, UNIVAC I, IBM, and Ferranti Mark I were prominent.
Machine and Assembly languages were introduced.
Data storage used magnetic drum memory (non-volatile).
Input used punch cards to input information.
Limited applications with batch processing of input.

Second Generation of Computers (1950s – 1960s)

Vacuum tubes replaced with transistors.
Computers became smaller, faster, and more efficient.
Magnetic core memory improved speed and reliability compared to the 1st generation.
Programming was via machine language and later assembly language.
Example: IBM 704 and 7090, and UNIVAC 1108.
Introduced programming languages including Fortran and Cobol
IBM 704 (1954) developed using transistors

Third Generation of Computers (1960s – 1970s)

Integrated circuits (ICs) replaced transistors.
Improved reliability, smaller size, and higher performance for computers.
Time sharing, allowing multiple users to access one computer at the same time, was a key advancement.
The development of operating systems, such as IBM's OS/360 and DEC's TOPS-10, made computer use more accessible.
Third-generation programming languages (3GLs) such as COBOL, Fortran, and Basic emerged, making tasks easier for programmers.
More powerful, accessible, user-friendly computers.
Example: IBM System/360, DEC PDP-11, Cray-1, and HP 3000.

Computing's Fourth Generation Features (1970s – 1980s)

Microprocessors improved computing power.
Leading to significant improvement in miniaturization.
Mass production of computer components was possible.
Integrated circuits (ICs) made computers smaller and more powerful.
personal computers (PCs) were widely used.
Examples: IBM Personal Computer (PC), IBM System/370, Apple Macintosh, Commodore 64 (C64), and Atari 800 were typical Fourth Generation examples.
Programming languages like SQL, Visual Basic, Ada, and more.

Computing's Fifth Generation Features (1980s – 1990s)

Focused on artificial intelligence, natural language processing, expert systems, parallel processing, and distributed computing.
The goal was to develop computers with human-like intelligence, capable of using natural languages, identifying patterns, and making decisions.
Artificial intelligence (AI) was intended to use a database of knowledge and reasoning methods to replicate human problem solving.
Despite ambitious goals, the project was terminated due to budget issues and technological constraints, but inspired further research.
Examples of programming languages: Prolog, Concurrent Prolog, Mercury, OPS5, LISP, Miranda, SQL, SAS, ADA, and VHSC language.

Fourth Generation Computers (1970s-1980s) Key Features

Increased Memory Capacity: DRAM technology enhanced memory capacity, leading to the creation of more powerful and sophisticated applications.
Operating Systems: Improvements led to more powerful, user friendly, and versatile operating systems, handling multiple tasks simultaneously.
User-Friendly Interfaces: Graphical User Interfaces (GUIs) made computers more accessible to a wider range of users.
Networking: The development of Advanced networking technology enabled computers to share resources, communicate more efficiently and work together in networks such as LANs and WANs.

Fifth Generation Computers (1980s-1990s) Key Features

Artificial Intelligence (AI): Computers were developed to mimic human decision-making processes using natural language processing.
Parallel Processing: This technology allowed computers to perform multiple tasks at the same time, significantly increasing processing speed.
Distributed Computing: Computers could be networked to work together to solve problems and increase processing power.
User-Friendly Interfaces: The user interface was further refined, making computers more intuitive and accessible.
