Storage unit for computer data

Computer data storage units, commonly used units have "bit", "byte", "word".

Bit: This is the smallest unit of data, which represents one binary data.

Bytes: Consists of eight-bit binary data. Bytes are the most common basic unit in the data store. We often say that memory is 2G, and here the units are bytes. 1 k equals 1024 bytes, 1M equals 1024k,1g equals 1024M.

Word: A combination of bits, handled as a separate unit of information. Depends on the type of machine, the word length and the user's requirements. The commonly used fixed word lengths are 8, 16, 32, and so on.

Machine word Length: In the discussion of information units, there is a machine hardware indicators related to the machine length, generally refers to the register to participate in the operation of the binary number of bits, which represents the accuracy of the machine, such as 32-bit, 64-bit. Is the 32-bit machine or the 64-bit machine we used to talk about.
