7

What are the 2statements of Moore's Law?

Book says: speed of a chip doubles every 18 months (faster)
Rock says also:chip performance per dollar doubles every 18 months(cheaper)

8

what are 3 extensions of moore's law

processing speed, storage capacity, and communication speed all continue to increase

9

What is the motherboard

the ting that every part connects to

10

what is the cpu

the central processing unit that runs the software; selects instructions, processes them, performs calculations and stores them in the memory

11

what is the video card

created images that appear on the monitor

13

Hard disk

holds information (long term)

14

Optical Drive

reads disks

15

Difference between volatile & Nonvolatile memory

volatile needs power (RAM), non volatile ca store without power, (Hard disk/drive)

16

What is flash memory and what makes it so great

it is a hard drive with no moving parts. making it nonvolatile and solid state

17

What is the HDD

Hard disk drive

18

What Is SDD

flash memory

19

What is IGC and do you want it?

integrated graphics card, not as good as a DGC or dedicated graphics card which can speed up different computer games

20

How is the speed of a harddrive measured

RPMs you want higher rpms

21

What is MTBF

Mean TIme Between Failure. Most of the effort of IT is keeping your existing mess running

22

What is the theoretical 6th Wave of computing?

QUANTUM computing. where bits are ones and zeros at the same time (QUIBITS)

23

What is the 6th sense

is the internet sense. computer aided everything; wearables to the extreme

24

What is IOT and another name for it

Internet of Things, Machine 2 Machine communication

25
