Normally, the data path width for DIMMs
is 64 bits but for the DIMMs that support ECC, the data path is 72 bits.
To add, error checking uses
the extra 8 bits. ECC memory is more reliable than non-ECC memory but it costs
more than a non-ECC memory. Comprising the DIMMS are a series
of dynamic random-access memory integrated circuits. Mounted on a
printed circuit board, these modules are designed for use in personal
computers, workstations and servers.
The most common kinds of internal data corruption are
detected and corrected by a type of computer data storage called error-correcting
code memory.

Answer:
a) The domain of f(x) is .
b)
The inverse function is:
So we need
Applying ln to both sides
So the domain of f(x) is .
(b) Find F −1 and its domain.
is the inverse function of f.
How do we find the inverse function?
To find the inverse equation, we change y with x to form the new equation, and then we isolate y in the new equation. So:
Original equation:
f(x) = y = \ln{e^{x} - 3}
New equation
Here, we apply the exponential to both sides:
Applying ln to both sides
The inverse function is:
The domain is
is always a positive number, so it is always going to be larger than -3 no matter the value of x. So the domain are all the real values.
slope = (y2-y1)/(x2-x1)
m =(-2-7)/(8-0)
m =(-9/8)
slope is -9/8
the y intercept is 7 (0,7)
y = mx +b
y = -9/8 x+7
Answer: y = -9/8x +7
