The Cafes » Internet

This morning I’m sitting at the computer pruning my address book for Christmas cards. (Yes. I’m running late.) As usual I discover a few incomplete addresses. Missing zip codes are especially common. I know there’s a zip code lookup finder on the USPS web site somewhere, but rather than Googling for it on a whim I paste an address into the Firefox location bar.

Bam! Up pops the complete address including zip code! Five or six more and I’m done. Easiest data cleaning I’ve ever done, and maybe a few more people can get their cards before New Years.

The Internet is 30 today. Exactly 30 years ago today on November 22, 1977 the first three networks were connected to become the Internet. These three were:

• ARPAnet
• A lossy packet radio network (the lossiness of this network greatly influenced the design of TCP/IP)
• The Atlantic Packet Satellite Network (a.k.a. SATNET)

There were computer networks before this, but this was the first network of networks that deliberately attempted to connect heterogeneous systems without regard for platform. It was the thing which grew into today’s Internet. Except for one brief discontinuity in 1983 when the entire Internet was turned off to switch over to TCP/IP, there’s a continuous progression from then to now.
