Paper Two: Major Developments in technology

Question 1

micro-electronics (definition)

Answer 1

miniature electronic devices and systems facilitated by the development of the integrated circuit (IC)

Question 2

benefits of transistors vs vacuum tubes (3)

Answer 2

• much smaller allowing elopement of ICs, smaller = more compact tech
• Millions of transistors can be used on a single device- improved tech (eg medical scanners)
• more reliable & less likely to break

Question 3

Moore’s Law

Answer 3

the number of transistors in an integrated circuit (IC) will double approx. every 2 years

Question 4

key benefits of the internet (3)

Answer 4

• easier communication between countries & continents, available to public
• greater ease of access to information & more info available
• info more accurate & regularly updated

Question 5

how have microelectronics influence manufacturing processes?

Answer 5

• allow for automation
• eg CNC, robotics
  > allowed for mass & continuous production = more products & more profit
• allow for rapid prototyping > faster development of products
