Evolution of Computer Generations (1st to 5th)
1st Generation (1940s):
Mechanical computers with punched cards.
Limited memory capacity (16 characters).
Slow processing speed.
Used for basic data processing and accounting.
2nd Generation (1950s):
Vacuum tubes replaced by transistors.
Introduction of stored program capability.
Increased memory capacity up to 64 characters.
Increased processing speed.
Examples: IBM 650, UNIVAC I.
3rd Generation (1960s):
Transistors replaced by integrated circuits.
Mass production and standardization.
Introduction of high-density memory (RAM).
Magnetic disks replaced by hard disk drives.
Increased memory capacity and performance.
Examples: IBM System/360, DEC PDP-11.
4th Generation (1970s):
Microprocessors with multiple cores.
Introduction of personal computers (PCs).
Advanced graphics and sound capabilities.
Large amounts of RAM and hard disk storage.
Examples: IBM PC, Apple II.
5th Generation (1980s):
Personal computers with advanced graphics and sound.
Network communication capabilities.
Advancements in artificial intelligence and machine learning.
Emerging of mobile and portable computing devices.
Examples: Apple Macintosh, IBM PowerBook, Samsung Galaxy.
