Why is everything divisible by eight? Where did this all come from i.e 8 bit etc.

Short for binary digit, the smallest unit of information on a machine. The term was first used in 1946 by John Tukey, a leading statistician and adviser to five presidents. A single bit can hold only one of two values: 0 or 1. More meaningful information is obtained by combining consecutive bits into larger units. For example, a byte is composed of 8 consecutive bits.

Computers are sometimes classified by the number of bits they can process at one time or by the number of bits they use to represent addresses. These two values are not always the same, which leads to confusion. For example, classifying a computer as a 32-bit machine might mean that its data registers are 32 bits wide or that it uses 32 bits to identify each address in memory. Whereas larger registers make a computer faster, using more bits for addresses enables a machine to support larger programs.

Graphics are also often described by the number of bits used to represent each dot. A 1-bit image is monochrome; an8-bit image supports 256 colors or grayscales; and a 24- or 32-bit graphic supports true color.

Eight-It characterized the single slot that supports eight interrupts and four DMA Channels,It was first used in the 8 bit atari games,architecture could be built upon a multiple of 8 easier than any other number.

I believe the 8 comes about because of the Enlish language. It's to have a code for each alphabet and other special characters and at that time, some allowance. Since that's how things are back then, everybody stick to 8-bit and build on it. So now everything is based on that standard.
