Document Summary

Each operation is encoded in a form of instructions . Is symbolic, used in encoding of operation & destination of results. The set of possible instructions specific for each processor. All computer systems need memory for data and instructions. So there are two numbers associated with each memory location: address and contents. Addresses are almost always described as hexadecimal numbers. Machine language instructions (which may be one or more bytes long) Character codes such as ascii (7 bits) or unicode (16 bits)
