...node
Some architectures, such as the iPSC/860, do not let the network interface access memory directly. Instead, the network interface consists of a send and a receive FIFO. A program has to read and write the FIFO for each word transferred. Access to the FIFO registers has to be controlled to prevent applications from reading data that is intended for another process.

...sandbox
As Charlie Crowley points out, the term sanboxing is misleading to a parent. A playpen is used to keep children within a given space. A sandbox does that only when the children cooperate.

...R-code
The name R-code was chosen since P-code [106] and U-code [12] already exist. Any relationship to the author's initials is purely coincidental.
