Answer:
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Explanation:
We can calculate the channel capacity using Shannon's Capacity formula:
C = B + log₂ (1 + SNR)
Where C = Channel Capacity
B = Bandwidth of the Channel
SNR = Signal to Noise Ratio
We are given SNR in dB so we need to convert it into a ratio.
= 10log₁₀ (SNR)
10 = 10log₁₀ (SNR)
1 = log₁₀ (SNR)
SNR = 10¹
SNR = 10
So, using Shannon Channel Capacity formula:
C = 10 x 10⁶ log₂ (1 + 10)
C = 34.5 MHz
Total amount of time required to transmit a 1MB file:
1MB = 1 x 8 Mbytes = 8Mb
C = 34.5 MHz = 34.5 Mb/s
Time required = 8Mb/34.5Mb/s = 0.23 seconds
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Answer:
A. Property rights allow consumers and producers to make free
choices.
Explanation:
If the consumers and the producers have the properties, then only they can say that well this is free for you, or in other words, can make the free choices. And by no means market forces only work when everyone owns some property, as some also cannot have the property, and hence work hard to earn some property, and thus the Market force does work. And the laws have nothing to do with the free market or the non-free market. And as we saw above, the competition can exist if someone owns the property, and others do not. Hence, the correct answer is A.

LIPS a functional language is one in which computations are made primarily by applying function to given program
Answer:
The appropriate guidelines to create and manage files in the passage:
O. First, (select a central location to organize all your files, folders, and sub-folders).
O. Then double-click the folder or folders to identify which file you want to move.
O. Now (use Windows Explorer to navigate and paste the file in the
required location).
The correct text in the passage is:
O. It is a great idea to (categorize your data into folders.) It is even better to (segregate them further into sub-folders.) If you maintain a list of sub-folders under every main folder, you will be able to access all your tasks easily. For example, you could put your school subjects under different sub-folders to organize your data efficiently on your computer.
