Answer:
def normalize(text):
text = text.lower()
text = text.split()
return text
Explanation:
The functiinfunction is provided with an input text when called upon, then it changes every character in the text into lower case and split each word with a space.
Answer:
t= 8.7*10⁻⁴ sec.
Explanation:
If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.
As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.
Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:
If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:
⇒ t = 8.7*10⁻⁴ sec.
Answer:
Selective Repeat protocols
Explanation:
It is better to make use of the selective repeat protocol here. From what we have here, there is a high error rate on this channel.
If we had implemented Go back N protocol, the whole N packets would be retransmitted. Much bandwidth would be needed here.
But we are told that bandwidth is limited. So if packet get lost when we implement selective protocol, we would only need less bandwidth since we would retransmit only this packet.
Answer:
B- Workgroup model
Explanation:
A workgroup model can be defined as a process which enables system to be peer together in order to access the resources shared like files and printers at the same time.
In work group microsoft operating systems tend to share files, printers, and even Internet connection among them which is why work group is important especially in a place in which their are various computers with limited files and printer or internet connection.
Answer:
The invention of flashlight is associated in the late period of industrial revolution.
Explanation:
- During the industrial revolution, Europe and United States flipped the use or technology in the manufacturing processes of industries.
- At the time of industrial revolution many chief inventions like, steam engine, dynamites etc. were made that the traditional history and reformed the technology.
- Thomas Edison in 1879, invented the battery and flashlight at the late period of industrial revolution which was also a major invention
