Figure out how many bars you have to rap on. A bar is simply one line of your song. Most raps are built out of 16 or 32 bar verses though they can be as short as 8 or 12 bars as well. If you're writing the whole song yourself you might have 2-3 verses and a hook.
In addition to being a great tool for command-line aficionados, bcp is a powerful tool for those seeking to insert data into a SQL Server database from within a batch file or other programmatic method.
Bridge Protocol Data Unit. Bridge Protocol Data Units (BPDUs) are frames that contain information about the Spanning tree protocol (STP). Switches send BPDUs using a unique MAC address from its origin port and a multicast address as destination MAC (01:80:C2:00:00:00, or 01:00:0C:CC:CC:CD for Per VLAN Spanning Tree). For STP algorithms to function, the switches need to share information about themselves and their connections. What they share are bridge protocol data units (BPDUs). BPDUs are sent out as multicast frames to which only other layer 2 switches or bridges are listening.
