EVOLUTION OF TECHNOLOGY/ GLOSSARY/ UNIT 5

 

The Evolution of Communication Technology

In the past, communication technology was slow and limited. People relied on letters that took days or even weeks to arrive. In the 20th century, devices like the telegraph and landline phones allowed faster communication, but these methods were still restricted by distance and access. The floppy disk was an early way to store and share digital information, though it could only hold a small amount of data.

Nowadays, technology has evolved dramatically. With the internet and smartphones, people can communicate instantly through emails, text messages, and video calls. Social media platforms let users share information in real time, breaking the barriers of distance. Modern devices like laptops and tablets are portable and powerful, allowing work, study, and communication from anywhere.

The difference between past and present technology is clear — from slow, physical methods to fast, digital solutions. While older devices laid the foundation, today's technology connects the world more efficiently than ever before.
