Study Notes

The History of Computers

The first mechanical adding machine, the abacus (also known as a calculating frame), was invented in 1642.
John Napier invented the logarithm idea, which gave rise to the slide rule invented by William Oughtred.
The evolution of computers is divided into five generations.
The first electronic computer, the Atanasoff Berry Computer (ABC), was developed by John V. Atanasoff in 1937.

First Generation (Vacuum Tubes): 1939-1954

Computers in the first generation were expensive and bulky.
They solved problems one at a time using machine language.
Computers during this phase didn't support multitasking.
Vacuum tubes were used to amplify, switch, and modify electrical signals.
Computers from the first generation:
- ABC (Atanasoff Berry Computer) - Developed in 1937
- ENIAC (Electronic Numerical Integrator And Computer) - Developed in 1943
- EDVAC (Electronic Discrete Variable Automatic Computer) - Developed in 1949
- UNIVAC (Universal Automatic Computer) - Developed in 1951

Second Generation (Transistors): 1954-1965

Transistors replaced vacuum tubes, making computers smaller, more reliable, and less expensive.
High-level programming languages like FORTRAN and COBOL were introduced.
Computers in this generation introduced the concept of storing data on magnetic tapes.
Transistors are semiconductor devices that control the flow of electricity.

Third Generation (Integrated Circuits): 1965-1980

Integrated circuits (ICs) replaced transistors, leading to further reductions in computer size and cost.
ICs allowed for more powerful and faster computers capable of multitasking and real-time processing.
The development of the operating system (OS) paved the way for user-friendly interfaces.

Fourth Generation (Microprocessors): 1980-present

The invention of the microprocessor, a complete CPU on a single chip, revolutionized computing.
Personal computers (PCs) became widely available and affordable.
The graphical user interface (GUI) made computers easier to use.
The use of the internet and the development of the World Wide Web interconnected computers worldwide.

Fifth Generation (Under development): 1991-beyond

Artificial intelligence and natural language recognition will be the driving force of the fifth generation.

What is a Computer?

A computer executes programs and tasks through the Central Processing Unit (CPU).
The CPU's capabilities determine the power of a computer.
A program is a set of instructions that the computer follows.
Computers understand machine language, which is a simple language written in binary code.
Main memory consists of locations numbered by addresses.

Four Parts of a Computer System

Hardware: The physical components of a computer used for input, output, and overall control.
Software: Instructions that tell the computer how to operate and perform tasks.
People: Users who interact with the computer and software.
Data: Raw facts and information that the computer processes.

Capabilities of a Computer

Arithmetic operations: Addition, subtraction, multiplication, division.
Logical operations: Comparing values to determine if one is greater than, less than, or equal to another.
Data storage and retrieval: The ability to store and access data through memory.
High-speed processing: Quickly performing operations on data.
Automatic operation: Following program instructions without human intervention.

Limitations of Computer

Dependence on input: Computers need data and programs to function.
Limited creativity: Unable to simulate human qualities like creativity, humor, and emotions.
Vulnerability to failures: Hardware or software issues can lead to malfunctions.

Looking Inside the Computer

Processor (CPU): Responsible for carrying out instructions and calculations.
Memory (RAM): Temporary storage for data and instructions currently being used.
Input/Output (I/O) Devices: Allow interaction with the computer.
- Input Devices: Keyboard, mouse, scanner, microphone.
- Output Devices: Monitor, printer, speakers.
Storage: Stores data permanently.
- Hard Disk: Primary storage for the system.
- Optical Drives (CD/DVD): Used for reading and writing data on CDs and DVDs.

Key Points of the text:

The evolution of computers is marked by advancements in technology, leading to smaller, faster, more powerful machines.
Each generation of computers is distinguished by the type of technology used for the Central Processing Unit (CPU).
There are four main components to a computer system: hardware, software, people, and data.
Computers have a variety of capabilities, including processing data, storing information, and interacting with the user.
However, computers are not capable of thinking for themselves and are limited in areas like creativity and emotional intelligence.
