To describe bytecode markers, first it's important to understand what
bytecode is. Taken off of WhatIs:

"Bytecode is computer object code that is processed by a program,
usually referred to as a virtual machine, rather than by the "real"
computer machine, the hardware processor. The virtual machine converts
each generalized machine instruction into a specific machine
instruction or instructions that this computer's processor will
understand. Bytecode is the result of compiling source code written in
a language that supports this approach."

It continues into more detail, but you can read the link at the bottom
for yourself. Bytecode markers, are certain places, or markers in the
bytecode which are important, such as discussed in the messageboard
discussion linked below. They are usually discussed in terms of an
offset, size, and description. The offset is howfar from the beginning
of the file is the bytecode marker, the size is how long the marker
is, and the description is what exactly the marker describes. Hope
this was some help to you.
