SAP Basis Component Naming convention

Hi Experts,

I am very much confused about the Naming convention used by sap for most of the Basis components.How can i become familiar with them as they are hard to remember.

For Example:

BC-CCM-PRN:for SAP Printing.

BC-CST-GW: RFC Gateway
SO as there may be 1000 of components which are required to lock an incident to sap.

So please help me out how many components are there and how to find the right component name and how can i remember them?

Thanks in advance.
