Files stored on the hard disk，HDD minimum storage units called "sectors" (Sector)。Store 512 bytes per sector (equivalent 0.5KB)。
Operating system hard to read when，Not read a sector，Such efficiency is too low，But sequential read more sectors at once，That is a one-time read "block" (block)。This from a plurality of sectors "chunks"，It is the smallest unit file access。Size "chunks"，The most common is 4KB，That is a block consisting of eight consecutive sector。
Data files are stored in the "block" in the，Then it is clear，We must also find a place to store meta-information file，For example, the creator of the file、File creation date、File size, etc.。This storage area file meta information is called inode，Chinese translation for "inode"。
