 > :book: ***What is RPC?*** `bitcoin-cli` is just a handy interface that lets you send commands to the `bitcoind`. More specifically, it's an interface that lets you send RPC (or Remote Procedure Protocol) commands to the `bitcoind`. Often, the `bitcoin-cli` command and the RPC command have identical names and interfaces, but some `bitcoin-cli` commands instead provide shortcuts for more complex RPC requests. Generally, the `bitcoin-cli` interface is much cleaner and simpler than trying to send RPC commands by hand, using `curl` or some other method. However, it also has limitations as to what you can ultimately do.
