This talk discussed the developments in computer technology as witnessed by speaker, Brian. He talked briefly of the   areas of  hardware  development to the fantastic speeds, capacities and power we have today, also,  automatic data capture  from MICR , Bar code , OCR, and digitising of photos and videos  and movement.
Many forces pushed the development of networking  including the SWIFT ( Society for Interchange of Financial Transactions) and major corporations but ARPA ( Advanced Research Projects Authority) really developed the Protocol which  when adopted allowed all networks to communicate and became the Internet standard we have today. 
The advent of Fibre optic cables increased transmission rates , when laid under sea and overland  these have   enabled  our mass worldwide communication.

Corporations such as Boeing fostered and pushed computing development so that today designers design products on line from terminals around the world using sophisticated CAD systems and developed  in computer  assembly followed by robot assembly.
These developments now mean that organisations can use the technology to place their manufacturing, financial, management, medical  and accounting operations wherever is best suited to their strategy and still maintain communication and control.

The personal use of these facilities,  including the pushing of digital TV  and the flow of TV through free to air and the internet ,has had huge social implications for individuals, family  and communities.  It also remains to be seen whether or not we can
manage the security and  cross border issues.
