Communication Essay Electronics has played a major part in communication and the developments of it. The first ways of communication not by just talking were the uses of cans and a piece of string. This worked by the vibrations of the voice vibrating down the string and into the other person's can. The next major development was the invention of telephones. The first telephones were large and ugly with large numbers and were difficult to hear, and the switchboards were done manually by women and children. The next part of communication was the internet. This was first brought into use by the armies who wanted to move data from one computer to the other without the use of disks etc. Next was the mobile computer, or the laptop.

Broadband is also helping the file sharers as with standard 512k/s broadband they can download nearly 10 times as much data as a 56k/s dial-up connection. Also the compression codecs for movies and music means that they can be made a lot smaller with the same high quality being preserved. However some record companies have been releasing "fake" music files into the sharing domain. Normally these are 30 seconds of the song, which then fade into nothing for the rest of the song. Other companies, for one Madonna's have released her swearing and screaming about how she hates file sharers and how they are costing the industry millions. Alistair Braidwood 11D ...read more.
