Network Impact On Daily life - Part 2

Networks changing the way we live, learn, play, and work

Networks changing the way we live:

•  Early communication relies on face-to-face conversation. As our society advances, other means of communication emerged.

Mail (written message)

Telephone (voice) 

Television broadcast (one-way video communication). 

• With the use of the Internet, all the different types of communication are converging into Web-based communication. 
• Early data networks were limited to exchanging character-based information between connected computer systems. 
•  Current networks have evolved in mainly two ways: 

•    They can carry various types of information: text, graphics, voice, video streams. 
• They can support different types of devices: computers, PDAs, mobile phones, webcams, refrigerator, microwave. 

• National borders, geographic distances and physical limitations become less relevant.
