Answer:
Passive solar heating system
Explanation:
The goal of passive solar heating systems usually refers to the system in which the energy provided by the sun is used for heating and cooling of the living places in a house.
When sunlight falls on the house, the building elements capture the heat energy of the sun and it later releases back this heat when the sun is not there. The main objective of this system is to regulate the room temperature. It is comprised of two main elements, one is the glasses that face towards the south and a thermal mass that is used for heat absorption, storing and distribution of heat.
Answer:
e(a) = 0
e(b) = 10
e(c) = 110
e(d) = 1110
Explanation:
The Worst case will happen when f(a) > 2*f(b) ; f(b) > 2*f(c) ; f(c) > 2*f(d) ; f(d) > 2*f(e) and f(e) > 2*f(f).
Where f(x) is frequency of character x.
Lets consider the scenario when
f(a) = 0.555, f(b) = 0.25, f(c) = 0.12, f(d) = 0.05, f(e) = 0.02 and f(f) = 0.005
Please see attachment for image showing the steps of construction of Huffman tree:- see attachment
From the Huffman tree created, we can see that endcoding e() of each character are as follows:-
e(a) = 0
e(b) = 10
e(c) = 110
e(d) = 1110
e(e) = 11110
e(f) = 11111
So we can see that maximum length of encoding is 5 in this case.
Answer:
SCSI.
Explanation:
It is a set of ANSI-developed simultaneous interface requirements for connecting scanners, drives, printers, and many other devices to systems.
Although when Tim has such an outdated network system which is used as a backup by his corporation. Then hard drive may have gone wrong and required replacement. The connector used by the hard disk drive is not something he has ever seen before, but he upload photos of that on the community board of the organization to aid determine what kind of hard disk drive they will also have to order.
So, according to the following scenario he required SCSI cable.
