IO - Vectored operations (scatter/gather)

> I/O - (Input/Output|Read/Write) - Data Access

1 - About

In computing, vectored I/O, also known as scatter/gather I/O, is a method of input and output by which a single procedure-call sequentially:

The buffers are given in a vector of buffers (a set of buffers)

Scatter/gather refers to the process of gathering data from, or scattering data into, the given set of buffers.

Scatter/gather is a technique through which bytes can be read from a stream into a set of buffers (vectors) with a single read() invocation and bytes can be written from a set of buffers to a stream with a single write() invocation.

Vectored I/O can operate synchronously or asynchronously.

The main reasons for using vectored I/O are efficiency and convenience.
