32-bit and 16-bit CPU characters count?

1. The definition word is determined based on the characteristics of the processor.
First, arm is a 32-bit processor, so its word is 32-bit. A half word is naturally 16bit;
Bytes are 8bit regardless of the CPU.
If on MSP430, because it is a 16-bit processor, its word is 16-bit. Half word = byte = 8bit.

2.
One word: How many machines are exactly the number of digits, 32-bit machines -- 32-bit, 16-bit machines -- 16-bit (the CPU processes the data processing length at a time)
One word (Chinese character) occupies two bytes

3.
The word length is determined by the provider of the current data,
