little Gb is GIGA-bits and GB is gigabytes a byte is what ever the bus with is the CPU is IE> a 32 bit CPU uses 32 bit bytes, 64 bit cut is 64 bit bytes etc.
Not quite. There isn't always an "s" on the end. It can be read either way, sort of like mm and cm, or written either way but the "s" is not a constant. It is not so uncommon to see "1 GB" and "1 Gb" also which would indicate single measurements and therefore not be read or written out with the "s" on the end.
A byte is not the bus inside of the CPU. A byte is 8-bits. It goes back to binary coding. Binary is written in three groups of eight digits being either 0 or 1. Each digit either 0 or 1 consumes 1 bit to store the information.So a full line in binary, 00000000.00000000.00000000 would require 24 bits to store. Or just 3 bytes.
In computers connections, typically called a "bus" the "bit" used is different. For example, each memory channel to the CPU has a 64-bit connection to the CPU. What this is directly referring to is the existence of 64 wire connections connecting them. The reason for these connections often being called "bits" is owing to the ability of them each to be transferring a single bit of data at the same time. Of course that is increased by clock speed, but in basic that is why they are called bits.
