when the internet was first invented, you had to connect your router to the phone line and directly to the computer now you just connect your phone line to the router and the router provides wi-fi signals throughout a certain range

Router

wireless router that allow access to as many devices as possible when back i the old days only one computer could run on the line

Public

you can now gain access to internet in places un imaginable, on planes or even underground.

LAN

The LAN allows all devices connected to the network to gain access to the internet, files and documents.

Digital TV

Bandwidth

you can now send and recieve files in hyper speed due to the extreme bandwidth speeds it would take only a matter of seconds to send a file from one computer to the other

digital

what ever happens to the signal wave, it could be retrieved if run through a filter

analogue

could be distrupted by weather conditions

Connetion

Satellite Connections

satellites were never used to provide internet connection but might have been used to allow calls and communication via phones

cell phones used to have this long antennae that would act as a base of recieving satellite waves now cell phones dont have antennae and can be used wherever you are

DSL

cables had to be joined from the modem/router to the main phone line to be able to dial the inter service provider for internet access

using the phone line would have automatically disconnected you from the internet so it was either phone or internet

Fibre Optics

no fibre optics existed

Costs

prices of internet connections have dropped dramastically from when it was first imtroduced

Speeds

dial up was the only way to connect to the internet with a speed of about 56 Kb/s, compared to today , this is as useless as a tc with no speakers

now we have different methods of connecting to the intenet with a variety of speeds reaching up to 1 Gb

Hyperlinks

Text

things had to be handwritten or typed on a typewriter that would give out very poor quality printouts with only black ink. you now have color printers different font sizes, types and much more.

Images

High resolution

images quality used to be terrible and you wouldnt have the ability to zoom in so much and still see the image clearly, you would see the pixels overlaping each other

Video

3D

3D technology gives you the ability to watch videos with the three dimensions width length and depth (watch video the way you see in real life)

High definition

back in the 1970s, colored videos never existed. Video existed in black and white, now you have high definition video that allows you to see things at a higher level of what the eye can see

Audio

Music

Speech

audio was transmittesd through radio waves. These waves were analogue. Analogue waves were disturbed by weather conditions ie, if you would switch on the radio 20 years ago, most channels would give you a scrambled sound
