THE INTERNET!

• 50 years ago the Internet was not even thought of or imagined, the basic usage for a computer was a basic database, and yet only one program can be used at once, limiting the activity progress.They had to be cooled constantly.Programming was manual work l it lead to bugs and virus’s.


• Batch processing; 1 process at a time (took a program to run, and ran yours and someone else’s and the results were printed and given to you; time sharing is a number of things going on at once)


• Time sharing, first idea to share information from one computer to another; whilst using multiple users.


• Around 1941 DARPA (defense advanced research project agency) was formed. Where they were researching how knowledge was transferred by people to computers.


• ARPANET would stop information from doubling up.


• 1966, the individuals didnt like sharing computers so they were giving their indivdual computer where they connected them to main frames, the little computer provided the information to the larger computer for the database.


• NCP (network control protocol) Transmission control protocol replaced it.
  Something to allow all the computers to share and connect with each other.


• File transfer was inspected, files where sent in smaller packets then reformed at the destination for quicker sending speed.


• Information always had a centre (larger database computer)


• Radio raves wud cause problems in atomic attacks, so they wouldn’t work anymore
  So now they use direct waves, but they don’t have long range.


• The French invented the INTER-NET A webbed connection of computers, data, etc (created a net like design).Connect the comps through gate ways.


• TCP finally merged the connections; creating the internet! (1990)
  They made a new set of rules so that it wud allow the internet to run, from a vote of majority.

The smaller computers connected to the main frame, sending signals and information to each other.
