Companies have emerged to facilitate this virtual connection to the home country.

Mostly though, the talk is about personal, if virtual, connection.

A fixed capacity bucket, associated with each virtual connection or user, leaks at a fixed rate.

That bandwidth is then dynamically allocated in real time across multiple virtual connections to both storage and network resources.

The instruction set supports the notion of a channel, a virtual connection between two threads.

This is a so-called "virtual" connection, meaning that it's sort of an agreement between the two endpoints that they are connected.

But some educators caution that schools need to consider what may be lost when real-life interaction is replaced by a virtual connection.

A single physical channel can multiplex several different virtual connections.

The switching mechanism is abstracted by means of a channel, a virtual connection between two threads.

An unlimited number of virtual connections is possible.
