Hi guys ,
Please someone explain me what is the meaning of word length of a CPU
Wikipedia says :" The size of a word is reflected in many aspects of a computer's structure and operation; the majority of the registers in a processor are usually word sized and the largest piece of data that can be transferred to and from the working memory in a single operation is a word in many (not all) architectures."
But I have no any clear idea about it
Need explanation about word length of a CPU
Hi Mila James,
Word length" or "Word size" of a CPU is simply the size of the data that the processor can process at a time.
Naturally, the different CPU processors support different wordlengths like 32bit or 64bit. For example, 32bit processor means the maximum register size of the word that the processor can handle is 32 bits.
In older version CPUs, max word length is about 16bits. Currently latest Intel and AMD processors supports word lengths as long as 64bits.
Also 64bit processors can run 32bit programs or applications since most of those processors are backward-compatible.
But the same for the reverse process is not possible.
