The Early computers
There were 4 ancestor computers named:
Abacus
Sky disk of Nebra
Antikythera mechanism
Tabulating machine
Why did they often break down easliy?
The operating system used a lot of electricity and power and they
didn't have the current technology to maintain and consistently remain in tack

Advantages of generations of computers
Second generationContained a transistor which made it:
- smaller - faster - cheaper - more efficient - more reliable Had symbolic programing languages Used vaccuum tubes for power, and magnetic drums for memory |
Third generationContained an integrated circuit or chip, developed in 1965-1974, which:
- increased its speed - held a miniaturized transistor - increased its efficiency - advanced in networking |
Visicalc and its importance
It was used as a serious business tool and applications for hoddy's to business. VISICALC also had spread sheet software.

The Concept of convergence
Digital Convergence:
- Video, voice and data share software coming together to form a new device
- All technologies that were stored in small boxes, will become together in one
big box communicating with everything else, forming a network
- Improving students lives and making it an easy study tool
- Ability to exchang
