Study Notes
Communication Evolution
- Early human communication began with gestures and smoke signals, evolving to cave paintings found in Bhimbetka, Madhya Pradesh.
- Development of symbols for words led to the creation of the first alphabet necessary for trade and record-keeping.
- Earliest writing dates back to the Bronze Age, with clay tablets over 5000 years old discovered in Mesopotamia (modern Iraq).
Pigeon Post
- Around 3000 years ago, homing pigeons were used for delivering messages, tying messages to pigeons' legs.
- Pigeons' natural homing abilities made them effective for long-distance message delivery, especially during battles.
Postal Services
- The first organized postal service is believed to have originated in ancient Persia, enhancing roads and building posting stations.
- The ancient Romans and Indian rulers further developed postal systems, which were modernized in the 19th century.
- Today, postal services facilitate the sending of letters and parcels, with payment typically made through stamps.
Key Inventions in Communication
- Printing Press: Developed by Johannes Gutenberg in the 15th century, it revolutionized book production by using movable metal blocks, making books cheaper and more accessible.
- Telegraph: Invented in the 1830s-1840s by Samuel Morse, it allowed for rapid message sending via electrical signals using Morse Code but has become obsolete with newer technologies.
- Telephone: Introduced by Alexander Graham Bell in 1876, it provided fast communication across the globe; today, mobile phones dominate.
- Radio: Invented by Guglielmo Marconi in the late 19th century, it became a prevalent source of news and entertainment before television.
- Television: First created by John Logie Baird in the early 20th century, it quickly became a major communication tool for both entertainment and education.
Computers and the Internet
- Early computers were large and bulky, but modern computers are compact and versatile.
- The Internet, established in the 20th century, interconnected computers globally, enabling rapid and varied forms of communication, including emails and social media.
- Current uses of the Internet extend beyond communication to include information access, online shopping, and bill payments.
Satellites
- Over 2000 satellites orbit Earth, enhancing global communication by transmitting signals across long distances and overcoming geographical barriers.
- Satellites facilitate live broadcasts and phone calls regardless of location, also aiding in weather forecasting and research through Earth imaging.
