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:
c. Compile time binding
Explanation:
Compile Time Binding is a term in computer programming that describes the interpretation of logical addresses to physical addresses at the time of compilation.
Therefore, given that in the compile time binding, compiler code is generated at the start of the location, and moves afterward, thus, if at any point the starting address location changes, then it will be essential to recompile the code.
Answer:
One major sign of a computer being hijacked is the use of system resource by unknown programs. For example, full memory, high cpu usage, slow start up, crashes and errors, and low avalible storage space.
Explanation:
Answer:
B and D.
Explanation:
An individual working as a network administrator is responsible for a variety of different tasks which can include the design of the network itself, security for the network, and identifying and fixing issues. This is done in order to keep the computer network up-to-date and functioning as intended within the company or organization.
Answer:
Check the explanation
Explanation:
Please find the code down
def selection_sort_descend_trace(numbers):
i=len(numbers)
print("Output: ")
for num in range(0,i-1):# traversing from 0 to N-2, total N-1 iterations
val=numbers[num]
start=num+1
end=i
t=0
for j in range(start,end):
if(val<numbers[j]):
remember=j
val=numbers[j]
t=1
if(t==1):# swaping onlf if greater number is available
temp=numbers[num]
numbers[num]=val
numbers[remember]=temp
for p in range(i):# printing
print(numbers[p],end=' ')
print("\n")
if __name__ == "__main__":
print("Enter the integers separated by space: ")
numbers=[int(x) for x in input().split(' ')]
selection_sort_descend_trace(numbers)
Taking input as string and splitting with space as delimiter , converting the split part to integer , finally append in the list.
