3. Which Channel type is the fastest ? ( )

a. ESCON-Express2

b. OSA-Express2

c. FICON-Express4

d. Token Ring

Expert Solution

1) b) The communication path from the Channel Subsystem to the control units and I/O devices

Channels have to communicate and help communicate with all the paths

2) b) Channel number, Control unit number, Device number

It helps to make a channel and it needs the channel number, device number and the control unit number

3) FICON-Express4

This is the IBM proprietary name meant for ANSI FC-SB-3 that is a mapping protocol for fibre channel protocol.

1. A disk drive manufacturer sells storage devices with capacities of one terabyte, 500 gigabytes, and 100 gigabytes with probabilities 0.5, 0.3, and 0.2, respectively. The revenues associated with the sales in that year are estimated to be $50 million, $25 million, and $10 million, respectively. Let X denote the estimated revenue of storage devices during that year. Determine the probability mass function of X, E(X), and Var(X).
