, what doubles for microprocessors during chip performance - Answer -calculations
Besides microprocessors calculations doubling, what else doubles during chip
performance - Answer -storage
semi-conductor - Answer -'computer chips', Could be talking about microprocessors or
storage chips
Microprocessor - Answer -the calculating brain of a computer. Intel dominates this
market in PCs, ARM (licensed) dominates smart phones
volatile memory - Answer -requires a charge to hold its value (e.g. the RAM in your PC,
which loses data when the power is cut)
non-volatile - Answer -retains value even when not charged (e.g. the flash memory in
your camera)
flash memory - Answer -An example of non-volatile memory. A kind of memory that
retains data in the absence of a power supply. e.g. CAMERA
price elasticity - Answer -How drastically demand responds to a change in price
(increase or decrease)
solid state electronic - Answer -Electronics without moving parts (e.g. Chips)
e-waste - Answer -Includes discarded products with a battery or plug including mobile
phones, laptops, televisions, refrigerators, electrical toys, and others.
reasons why e waste valuable - Answer --80x as much gold in one ton of cellphones as
