Q.23

CPUs typically depend on FAST memory known as "CACHE" to enhanceperformance. CACHE memory typically is _________________?

		located with the Hard Drive
		built into the CPU
		located near the DIMM module on the motherboard
		part of the "Chip Set"

Q.30 Laptop Computers and Integrated Mobile Devices [iPhone orAndroid] do what to minimize power use?

	a.	leverage the fastest desktop processors available in themarket
	b.	clock the CPU and RAM fast as possible
	c.	use high voltage chips because Power = Current/Voltage
	d.	use low voltage chips because Power = Current * Voltage

Q33.A PC runs on a system clock with period .2 nano-sec. It is designed to transfer 8 Bytes of data between the CPUand I/O device per clock cycle.

After 3 month which which equation below properly calculates thetotal amount of data that will be written to the I/O device?

		5G cycles/sec * 8 Bytes/cycle * 60 sec/ 1hr * 24 hr/1 day * 90days
		5M cycles/sec * 8 Byte/cycle * 60 sec/ 1hr * 24 hr/1 day * 90days
		.2G cycles/sec * Bytes/8cycle * 60 sec/ 1hr * 24 hr/1 day * 7days
		1 sec/2G cycles * 1 Bytes/cycle * 60 sec/ 1hr * 24 hr/1 day * 1wk

QUESTION 34

1. We have learned desktops/laptops, etc. have components andarchitecture similar to IoT and other electronic devices given:

   		they all leverage identical component sets
   		they all typically have some form of CPU + RAM + logic +storage
   		they all use PCI bus
   		they all use DIMM sockets to add memory
