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.
Word length is the number of bits that can be processed at one time.
the number of bits process at one time
Bandwidth
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.
The first microprocessor was the 4004. It could handle 4 bits at a time.
one number of host bits must be left when you doing subnetting.
A bit of memory holds a single character. Therefore the minimum number of bits would be one, but you would need one for each character of data.
A shift register is used for multiplying and devision. If a binary number of say Bin. 100101 (37 Dec.) is multiplied by 2 the bits have to be left shifted one time and the number will then be Bin. 1001010 (74 Dec.) and to divide by 2 the bits have to be right shifted
Eight bits are in one byte
There are 1,000,000 or 106 bits in a megabit.
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
