As quoted from Google Books, "Word size refers to the number of bits that a microprocessor can manipulate at one time."
Parallelism
8 bits totals one byte where one byte is roughly a single character such as 'A' or '1'
A binary number containing eight bits is referred to as one "Byte". A binary number containing four bits is referred to as one "Nibble".
log2 200 = ln 200 ÷ ln 2 = 7.6... → need 8 bits. If a signed number is being stored, then 9 bits would be needed as one would be needed to indicate the sign of the number.
As quoted from Google Books, "Word size refers to the number of bits that a microprocessor can manipulate at one time."
Word length is the number of bits that can be processed at one time.
the number of bits process at one time
Bandwidth
The term is used to describe the number of bits that a CPU can access at one time is bit rate. This is also written as a bitrate and uses the variable R.
Parallelism
The one who transmits more data bits in the same length of time, or the same number of data bits in less time, has the faster transmission rate.
The largest number of bits a CPU can process is word size. A CPU's Word Size is the largest number of bits the CPU can process in one operation.
An x86-based OS processes 32 bits at a time.
The first microprocessor was the 4004. It could handle 4 bits at a time.
one bit at a time
