In every Unix-like operating systems device files are used as interface to device drivers. Every device is represented in file system with a special file, these special files are called as Device Files. There are two standard types of device files: character special and block special. Character special files are used to interface character devices. Character devices transfer data in terms of character. Example of character devices mice, serial modems. Block special files are used to interface block devices. Block devices transfer data interms of blocks. Example of block devices hard disks, CD-ROMs.
For example struct tm and struct stat are often used by UNIX processes.
This network storage and data management software for Unix can be downloaded from Network Appliance (Net App). It backs up and restores your data, and make tasks simpler.

In computing, a block length is the length, in bytes or characters, of a block of data.
110-block is for data networking cable. The 66-block is for telephone cable.
Local data is automatic data associated with the block that is presently in scope. It is dynamic, usually allocated from the stack, and it goes away when you leave the block.
