Part of the concrete syntax given in the 1960 Report on ALGOL 60 is as follows: I -> if then if then else I begin end In the 1963 report on Algol, this was changed to: I ; then if then else -> statement> I begin end statement> -> Show using examples what if-statements in Algol looked like (with one or more statements in the then/else-parts).
Demonstrate with an example why the original syntax was unsuitable and why the revised syntax is an improvement.

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
