LAN

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

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

analogue

could be distrupted by weather conditions

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

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

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 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)

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

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
