Question

A block device transfers :

a) Bytes one by one
b) Block of bytes as a unit
c) With unpredictable response times
d) None of these

Answer 1

A block device transfers data in blocks of bytes, improving efficiency. It has predictable response times.

Step-by-step explanation:

A block device transfers data in blocks of bytes as a unit. It does not transfer bytes one by one. This is beneficial as transferring data in larger blocks reduces overhead and improves efficiency.

Block devices can have predictable response times as they operate on fixed-size blocks. This allows for better planning and optimization in data transfer.
