Shared memory: Where it belongs in the computer space

Shared memory technology is a part of a powerful IPC (interprocess communication) toolbox in UNIX-derived systems, which allows arbitrary processes to exchange data and synchronize execution. There are many forms of IPC on a UNIX-derived system (Several forms of IPC in the base UNIX toolbox are serial communication mechanisms. These linear forms have many uses, but I’ll be focusing on shared memory in this Daily Drill Down.)
