Study Notes

Defining Computers and Computing

A computer is an electronic device that receives, stores, processes, and outputs information.
It is a versatile tool with applications in communication, information access, entertainment, education, business, and creativity.
Computers are made up of hardware (physical components) and software (programs and instructions).

Types of Computers

Desktop Computers: General purpose, often placed on a desk, larger and more powerful than laptops, customizable and upgradable.
Laptops: Portable, designed for mobility, typically with built-in keyboards and screens, longer battery life than desktops.
Tablets: Mobile, touchscreen-based, ideal for reading, watching videos, and web browsing.
Smartphones: Pocket-sized, touchscreens, advanced features like cameras, GPS, and internet connectivity.
Servers: Powerful computers designed for high performance and reliability, storing and managing data for networks.
Supercomputers: Extremely powerful, used for complex calculations and simulations, have multiple processors and specialized hardware.

History of Computing

Early Mechanical Calculators (1600s-1800s)

1642: Blaise Pascal invented the Pascaline, a mechanical adding machine.
1673: Gottfried Wilhelm Leibniz invented the Stepped Reckoner, a mechanical calculator capable of multiplication and division.
1822: Charles Babbage designed the Difference Engine, a mechanical computer intended for calculating mathematical tables.

Electronic Computing (1900s-1940s)

1936: Alan Turing introduced the Turing machine, a theoretical model of a general-purpose computer.
1941: Konrad Zuse developed the Z3, the world’s first working programmable electronic computer.
1944: The Harvard Mark I, a large-scale electromechanical computer, was completed.
1945: John von Neumann proposed the stored-program concept, where instructions and data are stored in the same memory.

Transistor-Based Computers (1950s-1960s)

1947: The transistor was invented, paving the way for smaller, more reliable computers.
1951: The UNIVAC I, one of the first commercial computers, was delivered.
1956: The IBM 305 RAMAC introduced the first commercial hard disk drive.
1964: IBM introduced the System/360, a family of compatible mainframe computers.
