Abstract:
A Block device driver provides access to the block devices that transfer randomly accessible data in fixed size of blocks .All the mass storage devices are Block devices so they all need block driver i.e. Pen drive, hard disk .A block is a fixed size of junk of data determined by the linux kernel. Blocks are generally 4096 of bytes generally but their size depends on the architecture and the file system type . Block drivers are conduit between core memory and secondary storage because modern systems with virtual memory shift unneeded data to the secondary storage . Similarly a Sector is small size of block which size is usually determined by the underlying hardware. Today block devices becomes necessary part to store large amount of data .
Training Topics in brief:
