🦋🦋A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically.🦋🦋

🔻
🦋🦋Charles Babbage is considered as the “father of the computer”. He invented the first mechanical computer in the early 19th century.🦋🦋

🔻
🦋🦋The principle of the modern computer was proposed by Alan Turing.🦋🦋

📌📌First Generation (1940-1956)📌📌
🔻➖➖➖➖➖➖➖➖➖➖➖➖➖🔻
🔴They used: vacuum tubes for circuitry and magnetic drums for memory
🔻
🔴Memory and Storage: Magnetic tapes, magnetic drums as secondary memory
🔻
♦♦Extra Information:♦♦
🔻
⚫Very expensive to operate.
🔻
⚫Relied on binary machine language, the lowest-level programming language to perform operations.
🔻
⚫Binary Machine Language (0s and 1s) was difficult for users to understand
🔻
⚫Could solve only one problem at a time
🔻
♥Examples: UNIVAC and ENIAC computers
🔻

🔻
📌📌Second Generation (1956-1963)📌📌
🔻➖➖➖➖➖➖➖➖➖➖➖➖➖🔻
🔴They used: Transistors
🔻
🔴Memory and Storage: Main memory- Ferite cores. Secondary Memory- Magnetic disks and tapes
🔻
♦♦Extra Information:♦♦
🔻
⚫Computers became smaller, faster, and cheaper.
🔻
⚫Also binary Machine Language was replaced by Assembly Languages.
🔻
⚫Use of assembly Language allowed programmers to specify instructions in words.
🔻
♥Examples: IBM 1401 and Honeywell 400 computers
🔻

🔻
📌📌Third Generation (1964-1971)📌📌
🔻➖➖➖➖➖➖➖➖➖➖➖➖➖🔻
🔴They used: Integrated Circuits
🔻
🔴Memory and Storage: Main memory- RAM, ROM. Secondary Memory- Magnetic disks, tapes
🔻
♦♦Extra Information:♦♦
🔻
⚫Computers became more smaller and cheaper.
🔻
⚫Speed and efficiency of Computers was further increased by the use of semiconductors.
🔻
⚫Keyboards and Monitors were introduced for input and screen
🔻
⚫Different application could run at one time
🔻
♥Examples: IBM System/360, IBM 1130, UNIVAC 1107 computers
🔻

🔻
📌📌Fourth Generation (1971-Present)📌📌
🔻➖➖➖➖➖➖➖➖➖➖➖➖➖🔻
🔴They use: Microprocessors. VLSI (Very Large Scale Integration) technology
🔻
🔴Memory and Storage: Main Memory- RAM/ROM. Secondary Memory- Hard Disk
🔻
♦♦Extra Information:♦♦
🔻
⚫Thousands of integrated circuits were built onto a single silicon chip.
🔻
⚫Computers became more powerful.
🔻
⚫Computers could be linked together to form networks now, which eventually led to the development of the Internet.
🔻
⚫Graphic user Interface (GUIs), mouse and handheld devices were developed.
🔻
⚫Programming languages closest to human language
🔻
♥Examples: Apple Macintosh, IBM PCs computers
🔻

🔻
📌📌Fifth Generation (Present and Beyond)📌📌
🔻➖➖➖➖➖➖➖➖➖➖➖➖➖🔻
🔴They use: Artificial Intelligence. ULSI (Ultra Large Scale Integration) technology
🔻
🔴Memory and Storage: Main Memory- RAM/ROM. Secondary Memory- Hard Disk
🔻
♦♦Extra Information:♦♦
🔻
⚫Still in development.
🔻
⚫Some applications like voice recognition are used today also
🔻
⚫The goal of fifth-generation computing is to develop devices that respond to natural language (human language) input and are capable of learning and self-organization.
