unit 2-2HISTORY OF THE INTERNET在线视频

Hey there~ Welcome to life Noggin.

Thanks to this wonderful thing called internet, you are watching this video right now.

But how did the internet get to where it is today?

There is so much internet history that we could not possibly get to everything in this short video

So we are definitely going to make a second one.

Anyway, let¡¯s get started. The internet actually got started over 50 years ago.

And computers back then filled up the entire rooms.

Scientists and researchers used it for years to communicate during the cold war.

It was useful because if one computer went down, the others wouldn¡¯t follow

In 1962, a scientist, J.C.R. LICKLIDER proposed the idea of a networked computer

that could talk to one another

In 1969 the first ever message was sent from one computer to another over the APPANET,

the government¡¯s computer network at the time

APPANET stands for advanced research projects agency.

One was located in the research Lab in UCLA and the other at Stanford.

All the messages sent was logged in, and it didn¡¯t fail the crashed network.

Stanford only received the first two letters of the message.

But, hey, you got to start somewhere

By the end of the year, only four computers were connected to this network.

In 1971, the university of Hawaii¡¯s Aloha net was added,

followed by various networks in London and Norway two years later.

Also happening in 1971, Ray Tomlinson was developing 1st system to send mail back

and forth between users of the APPENNET.

This would eventually be called electric mail or email for short.

The @(at) symbol was used to tell a person¡¯s name and a host name apart.

With all of the networks floating around,

there needed a way for all of computers on them to communicate with other networks.

This is where a computer scientist named Vinton Cerf comes in.

He invented a way that introduce computers across the globe to each other in a virtual space.

This invention was called transmission control protocol or TCP,

which was followed by internet protocol or IP.

In the 80s, scientist used Cerf¡¯s protocol to send data back and forth,

but the 90s is where all these began.

in 1991, a computer programmer named Tim Bernes-Lee invented the world wide web.

This wasn¡¯t just a dead sharing space for scientists anymore, this was an entire network

You are using the browser right now to watch this video, some of the popular ones are firefox,

google chrome or safari, but in 1992, Erwise was created,

Erwise was an internet browser and the 1st to have a graphical interface.

A few browsers came before and after,

but in 1993 Mosaic was created and it would popularize surfing the web.

Mosaic influence many of browsers to follow including Netscape Navigator in 1994,

this became the most popular web browser

at the time accounting for 90% of web usage in 1995.

In the early 90s companies like AOL

and CompuServe started to provide dial-up internet access.

Dial-up is the method of connecting to the internet via the telephone line.

Your telephone line was plugged into a modem; the other end was plugged into a phone jack.

There was a period in history when you couldn¡¯t use your

telephone and internet at the same time. Without the internet, we obviously

wouldn¡¯t be able to access people from around the world in few seconds

Share ideas and educate those who might not get a chance elsewhere.

Also without the internet, I¡¯d actually have to talk to someone when I order a pizza.

Which, by the way, was the 1st thing ever purchased on the internet.

How would your life be different without the internet?
