Basic conception
master <–IO–> slave
- blocking or noblocking, if master can’t do anything when IO.
- synchronous or asynchronous, if master need to query state of IO.
IO, data from one place to another.
Classification
| blocking | noblocking | |
|---|---|---|
| synchronous | master can’t do other things and need to query state of IO | master can do other things and need to query state of IO |
| asynchronous | master can’t do other things and needn’t to query state of IO | master can do other things and needn’t to query state of IO |
