fetch-decode-execute

Compiles code one line at a time an runs that line after it is compiled.
Converts Java code into byte code that is run by the Java Virtual Machine
A cycle, where an instruction is fetched from the main memory and put into instruction register. The program program counter increases to get ready for the next cycle. Then the instruction is decoded electronically to determine which operation to carry out. Finally, the control unit turns on the correct circuitry to carry out the instruction, which may load a data value into a register or add two values together, for example.
