Q: 'Why 8?'
A: Well 8 bits is a byte which is small and easy to work with. but it's not always 8. you could have a 32-bit number that's negative etc. Depends on the hardware etc, but it's easier to manually figure out 8 bits vs 32 or 64
Q: How it's read
A: HD was almost correct in his range assessment; it's -128 to 127. The official name for it is 'Two's Complement' and here's a quick sample

Code:
0 1 1 1 1 1 1 1 = 127 0 1 1 1 1 1 1 0 = 126 0 0 0 0 0 0 1 0 = 2 0 0 0 0 0 0 0 1 = 1 0 0 0 0 0 0 0 0 = 0 1 1 1 1 1 1 1 1 = −1 1 1 1 1 1 1 1 0 = −2 1 0 0 0 0 0 0 1 = −127 1 0 0 0 0 0 0 0 = −128
