SQLPlus connects to a local or remote Oracle database using Oranet better known as sqlnet which was mentioned in the last line of Sybrand's response.

If you are on a PC or other remote server from the database then you have to install client software and in the case of SQLPlus it is what Sybrand called the thick cleint, which is the normal traditional full Oracle sqlnet cleint. Oracle pro* language support and tools (exp, imp, and sqlldr) may or may not be installed based on the desired level of features desired.

Beside the thick client there is a thin client used by java.
