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.

What's the difference between combinations and permutations?

Stells [14]

Answer:

The difference between combinations and permutations is that in permutations, the order matters, while it doesn't with combinations. For example, if you are given 5 numbers (1,2,3,4,5) and you have to determine how many 3 digit numbers you can make, that is a permutation question because 123, 231, 321, etc. are all different numbers. If, for example, we have to find how many ways three people can be chosen out of a group of 5, that is a combination question and you must use the combination formula as the order of the three people does not matter. Other than the order, combinations and permutations are the same
