The history of computing began with mechanical devices like the abacus. Charles Babbage designed the Analytical Engine, which is considered the first concept of a programmable computer. Ada Lovelace wrote the first algorithm, showing how machines could handle symbols, not just numbers. These early steps prepared the way for the digital age.
The first generation of computers used vacuum tubes. These machines were very large and consumed huge amounts of electricity. Later, transistors replaced tubes and made systems smaller and more reliable. This was followed by integrated circuits in the third generation.
The CPU is the brain of the computer.
It moved from simple circuits to powerful microprocessors over time.
Programming also evolved, with C and FORTRAN
making coding easier.
A famous formula is E = mc2, while H2O shows how
subscripts are used.
The Internet started with ARPANET, a research network. Tim Berners-Lee later introduced the WWW, making information easy to share. Email and file transfer soon became everyday tools. The web quickly changed how people learned and communicated.
"The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect." – Tim Berners-Lee
Connections shifted from dial-up to broadband and fiber.
Today, computers fit in pockets as smartphones.
Apps, cloud services, and AI shape daily life.
Security and privacy are now major concerns.
