Study Notes
Introduction to Computers
- Computers are versatile tools used across various fields, impacting industry, government, education, medicine, scientific research, law, services, and even art forms like music, movies, and paintings
- Computers excel at processing millions of instructions rapidly and with high accuracy
- They are capable of performing calculations, controlling operations expressible in numerical or logical terms, and executing tasks efficiently without fatigue
Early History of Computers
- Humans have historically relied on methods like finger counting and tools like stones, pebbles, and beads for arithmetic
- Early civilizations developed number systems to track astronomical cycles and manage business transactions
- The term "computing" refers to the act of calculating
- The evolution of computers has progressed through multiple generations, with each marked by significant technological advancements
Computer Generations
-
First Generation (1940-1956): Vacuum Tubes
- Vacuum tubes were used for circuitry, and magnetic drums served as memory
- Computers were large, consumed significant space, generated substantial heat, and were costly to operate
- Programming was done using machine language, and input was provided through punched cards
- Output was primarily displayed as printouts
- Examples: UNIVAC and ENIAC
-
Second Generation (1956-1963): Transistors
- Transistors replaced vacuum tubes, offering energy efficiency, reliability, and reduced heat generation
- This allowed for smaller and more efficient computers
- Instructions were stored in memory, which transitioned from magnetic drums to magnetic core technology
- Examples: IBM 1401 and IBM 7090
-
Third Generation (1964-1971): Integrated Circuits
- Integrated circuits enabled miniaturization, with numerous transistors placed on silicon chips, boosting computer efficiency
- This resulted in cheaper, more powerful, and reliable computers
- High-level programming languages like COBOL and FORTRAN were introduced
- Examples: IBM System/360 and IBM System/370
-
Fourth Generation (1971-Present): Microprocessors
- The microprocessor brought forth the fourth generation, integrating thousands of integrated circuits onto a single silicon chip
- This led to the development of personal computers (PCs) and the personal computer revolution
- The internet emerged during this generation
- Examples: Apple II, IBM PC, and Macintosh
-
Fifth Generation (Present and Beyond): Artificial Intelligence
- Still under development, fifth generation computing devices are based on artificial intelligence
- The goal is to bridge the gap between computing and human thinking
- Examples: AI-powered robots and machines
Data, Information, and Program
- Computers act as problem-solving tools
- They receive instructions and data, perform arithmetic and logical operations, and produce outputs based on these computations
Evolution of Computers
- The evolution of electronic computers is categorized into generations, each defined by a fundamental technological advancement that transformed how computers function
Brief History of Early Calculating Tools
2500 BC: Abacus
- The abacus was the earliest known calculating tool, used for simple arithmetic calculations
- It involved beads, cords, and represented numbers with beads positioned close to a crossbar
- Primarily used for addition and multiplication
1614 AD: Napier’s Bones
- Invented by John Napier, Napier’s Bones aided multiplication
- It consisted of rods representing digits 1 through 9 and a constant digit
- Each column on a rod represented a multiplication table
1633: The Slide Rule
- Invented by William Oughtred, the slide rule employed logarithms
- It featured two sets of scales joined together, with a space between them
- Used for performing operations like multiplication, division, addition, and subtraction
1642: The Rotating Wheel Calculator
- Developed by Blaise Pascal, this calculator utilized gears and levers
- Inspired by predecessors, Pascal designed this model at the age of 19
1822: The Difference Engine
- Created by Charles Babbage, the Difference Engine calculated mathematical tables mechanically
- Considered a precursor to modern computers
1890: Hollerith Tabulating Machine
- Herman Hollerith designed a tabulating machine using punched cards
- This machine electronically read and processed information from the punched cards
