The information age
Multimedia
Audio
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
Music
Video
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
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)
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
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.

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
Costs
prices of internet connections have dropped dramastically from when it was first imtroduced
Connetion
Fibre Optics
no fibre optics existed
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
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
Internet
WWW
search engine
browsers
information store
Communication

Digital TV
DVB
DBV systems distribute data in several ways
Microwaves
some waves reach up to a speed of 170 GHz
first used in 1888
Satellites
Cables
Fibre obtic cables
Optical cables send data at 182,000 km/s
These plastic-fiber cables are used mainly for digital audio connections between devices.
Satelllite
DVR
Quality
Bandwidth
analogue
could be distrupted by weather conditions
digital
what ever happens to the signal wave, it could be retrieved if run through a filter
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
Wireless
LAN
The LAN allows all devices connected to the network to gain access to the internet, files and documents.
Public
you can now gain access to internet in places un imaginable, on planes or even underground.
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
In home
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
