8 bits is a dollar so it's a cheap controller.

It means that its instructions, an its I/O arrangements are performed in groups of 8 bits, like 8 zeroes and ones, which are normally called a byte.
One of the most popular 8-bit MCU's out there is the 8051, of which there are many brands.
Have a look at its instruction set, and standard architecture.

The databus is 8bit wide. It's instructions can be longer (typically).

 

You can deal with 8 bit data. Example you can add, subtract 8 bit data
xxxxxxxx+xxxxxxxx=xxxxxxxx
8 bit data+8 bit data= 8 bit data (output)

Nothing if you program in C.

If you program in assembler, you wouldn't ask.
