Advantages and disadvantages of blocking and no-blocking I/O?

There are advantages and disadvantages for both blocking and non-blocking I/O. In case of blocking it require less effort to code, linear programming and has minor control. You have to wait for some time because it cannot do anything if it has not received IO fully. For the second one, parallel programming, need higher effort and maximum control. So it is recommended that non-blocking is better.

Advantages and disadvantages of blocking and no-blocking I/O?

Hi. When blocking IO you cannot do anything more, not until the IO is fully received. While with non-blocking IO, it queued IO request straight away and function returns. Under blocking mode, the I/O connects and receive operations until the process in the question is completed. Under non-blocking mode if a Winsock call cannot complete right away the call will not succeed.
