Since we're talking about microcontrollers (MCUs), I won't discuss the use of "networking" as we typically know it, which involves RJ-45 connectors, cables, ethernet and a TCP/IP stack on both devices. The use case for that is typically to have two or more computers communicate either directly through a LAN cable, or through some networking equipment such as a hub or switch.
This post explains the usage of my first embedded Rust driver, the Microchip 23x SRAM driver.
