32bit is a data type that has 4 bytes in length.

10110011 = 8 bits of binary code, which = 8 bits.

These 8 bits can be arranged to represent 256 different values (all the variations of 0's and 1's with those 8 digits), that's 1 byte.

It's common for systems and applications to represent numbers (integers) using 32bits (4 bytes). This in true for memory addresses and other basic functions in your computer, that's why your windows/CPU is a 32bit system (most likely, unless you bought the 64bit versions of them).

Yeah, I was bored enough to type this out. Anyway, the guy is most likely making a fool out of you guys.
