Embisyslabs is the Linux Device Drivers Training Institute conducts best Courses on Linux Block Device Driver. A block device generally requires fewer pins and can thus be placed in a smaller package than a word-addressed device. In addition, a block device interface to slower forms of memory, such as rotating media and NAND flash, is much easier to build than a word-addressed interface, and these slower forms of memory generally have a much larger capacity dollar-for-dollar than NOR flash..Courses on Weekend as well Weekdays in Bangalore Bengaluru India.
