1. Developments
Key Revision Points

2. Moore’s Law
1965 – Computer Scientist Gordon Moore predicted that power of computer processors would double every 18 months
Has proved to be accurate in the 50 years since

3. Other Improvements Computers now: Smaller Less expensive
Use less energy
Faster
Process/store more data

4. Limitations Input/Output Devices Communications links Software Design
Human users!

5. Recent Developments/Future Developments
Cloud computing
Games – better graphics, multi-player
Mobile Devices – Phones now more powerful than PCs from 10 years ago
New technology – wearable tech, street maps, Internet of Things (smart devices) AI

6. Human Like Behaviour?
One of the main goals of many computer scientists is development computers that exhibit more human like behaviour – currently can’t make “common sense” or complex decisions where they have to cope with unforeseen circumsatnces

7. Areas for Development More powerful processors may lead to:
Natural Language processing – surprisingly difficult for a computer
Translation – all languages
Virtual Reality
