Retail price data for n = 60 hard disk drives were recently reported in a computer magazine. Three variables were recorded for e

ach hard disk drive: y = Retail PRICE (measured in dollars) x1 = Microprocessor SPEED (measured in megahertz) (Values in sample range from 10 to 40) x2 = CHIP size (measured in computer processing units) (Values in sample range from 286 to 486) A first-order regression model was fit to the data. Part of the printout follows: __________.

Fern has set up a computer network for the entire building. Unfortunately, the signal strength diminishes as it reaches toward t
goldfiish [28.3K]

Answer:

signal repeaters.

Explanation:

The best device to use in this scenario would be signal repeaters. These basically grab an already existing signal and repeats it in a specific direction therefore amplifying the range. These devices are usually used when a large network system is not reaching certain devices that are located too far away. These devices are then placed in midpoints between the network and the device and aimed towards the direction of the device. It then picks up the existing signal and retransmits it to the devices' location so that the device can pick up the network signal and access it.

If a system contains 1,000 disk drives, each of which has a 750,000- hour MTBF, which of the following best describes how often
exis [7]

Answer:

once per month

Explanation:

The correct answer is - once per month

Reason -

Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs

So,

750/24 = 31.25 days

⇒ approximately one in a month.

Suppose an IP packet is fragmented into 10 fragments, each with a 1% (independent) probability of loss. To a reasonable approxim
Marysya12 [62]

Answer:

a. 0.01

b. 0.001

c. The identification field of the packet fragment can be used to uniquely identify and collate the fragments lost in transmission.

Explanation:

The probability of losing a packet is 10% or 0.1, so the probability of losing the packet twice during transmission;

= 0.1 x 0.1 = 0.01

When any fragments have been part of the transmission, the probability of the packet is dependent on the fragments;

= 0.01 x 0.1 = 0.001

The identification field is a unique 16-bit value assigned to an IPv4 packet, when a packet is fragmented for transmission, its field is used to collate the unique fragments in the packet.
