The logarithm of a number A in base B is the exponent E to which B has to be risen to give A. For example 2.2.2 = 8 So the the logarithm of 8 in base 2 is 3. Let's write it Log[2,8] = 3. An application in information technology among countless others is computing how many decimal (base 10) digits can fit in a byte (8 bits ) of information. With one byte we can represent numbers from 0 to 255, or 256 possibilities. So Log[10,256] = 2.408239965 is the number of decimal digits that fit in a byte of information. Let's write 2^3 = 2.2.2 = 8. Then one kilobyte of information is 2^10 bytes, one megabyte is 2^20 bytes and one gigabyte is 2^30 bytes.

Logarithms were used to do math before computers and hand held calculators came along. As an example if you take the logarithm of a number, divide that by two and then convert the logarithm back into a number you have the square root of the original number.
Hand held calculators use the algotirhm in many cases as it is easy to probram in a table of logarithms.

No, it's not relatet to IT. You're probably confused with "algorithm". Logarithm has to do with math. It means to what number do you have to power the base of the logarithm to get the number you're looking for. Example: Logarithm in base 10 of 100 equals 2.

The logarithm is the mathematical operation that is the inverse of exponentiation (raising a constant, the base, to a power). The logarithm of a number x in base b is the number n such that x = bn.

Wikipedia is an incredible source of loose recommendations. The believability of the articles in Wikipedia relies upon on how nicely the item is referenced and the reliability of the references stated. That suggested, there are additionally specific articles in Wikipedia that are biased, unreferenced and in accordance with comments, those articles would desire to be rejected.

yeah
logarithm is just exponential.
in computer memory the storage capacity has a relation to logarithm.
