Answer:
128 GB
Explanation:
Here, we are interested in calculating the total capacity of the disk.
From the question, we can identify the following;
Number of surfaces = 4
Tracks per surface = 131,072
Number of sectors = 2,048
Each Block size = 512 bytes
Mathematically;
Total data capacity of the disk = no of tracks * no of sectors * block size
= 131,072 * 2048 * 512 bytes
= 2^17 * 2^11 * 2^9 bytes = 2^37 bytes
1 GB = 2^30 bytes
So 2^37 = 2^7 * 2^30
= 128 GB

Answer:
The operation of 6*x only executes if x is greater or equal to 0, since x=-10 and -10 is less than 0, the operation does not execute. For this reason, the value of y using this code is None.
Explanation:
In python a function is defined with the syntaxis:
def function(x):
the operation to execute (x)
value to return
In this case, the function is foo and the parameter is x:
def foo(x):
if x>= 0:
return 6*x
The code starts by assigning a value to x. Then, the code asks if the value of x is grater or equal to 0, if this condition is meet, then the code returns the value of 6 times x, if not, then the code does not return a value. In this case, x is -10 and this value is not grater or equal to 0. Given that the condition is not met, then the code stops executing and the value of y is none.
Answer:
ECC RAM
Explanation:
ECC RAM is the most popular Random Access Memory out there that is used by most business servers. Dealing with big data for most huge businesses is crucial. The need to prevent loss of data requires that they purchase ECC RAM. ECC RAM automatically protects the systems from potential errors that occur in memory. Any abrupt changes in temporary data stored in ECC RAM are automatically corrected. This is achieved by an additional memory chip that acts as error detection for the other eight RAM chips.
