Computers are made of components like circuits and RAM, and software can be stored in the form of bytecodes like, say, Java bytecodes or C++ bytecodes. Where do bytecodes actually reside in a computer? How does a computer know how to interpret them?
Let's try to figure it out.
The first thing to notice is that a computer isn't really designed to understand bytecodes, they are designed to be interpreted by an interpreter. A computer has two essential parts: the memory, where the computer stores what's on it, and the processor, which can do things like multiply, add, and subtract. With RAM, the processor can just keep track of what's in the computer, but with bytecodes, the processor has to do more work.
For example, if the processor wants to know how to store bytecode in memory, it would need to load bytecode into memory. The processor would need to store which bytecodes go where in the memory.
However, there is more going on here than meets the eye. The processor must not just load the code, but keep track of what needs to be loaded as well. It needs to make sure that if a piece of code gets loaded twice, it should only load it once. The processor must keep track of which memory address has been used before, and which ones have not been used, and do that all quickly.
Let's look at how the processor does this for one piece of bytecode, a NOP. A NOP is a piece of code that does nothing. The processor can't actually store NOPs, because NOPs are not executable. They are just data that tells the computer what to do. The processor doesn't know what to do with them, but it must still keep track of what NOPs it has already stored. The processor must keep track of where in the RAM it has stored that bytecode.
To understand this better, let's look at a computer that's storing data from RAM in the form of a hard drive. The processor can't access the memory directly, so instead the memory is arranged in the form of a chain of chips and wires. The processor can read or write to the first chip in the chain, which is 01e38acffe
