patters, a
machine’s CPU and main memory are connectedby a collection of wires called bus. ◦ Through this bus, the CPU extracts(reads) datafrom main memory by supplying the address ofthe^

memory
cell
along
with
an
electronic signal telling the memory circuitry toretrieve the data. ◦ Similarly CPU places(writes) data in the memory.

The architecture of the machine describedin Appendix C
An Illustrative MachineLanguage(Contd.)^ ^ The encoded version of the machineinstruction consists of two parts:^ ◦^
Op-code:
Specifies which operation to execute. ^ Bit pattern of op-code fields indicates which elementaryoperations such as SHIFT, JUMP, is requested by theinstructions. ◦ Operand:
Gives more detailed information about the operation^ ^ For example in the case of STORE operation, indicateswhich register contains the data to be stored and whichmemory cell is to receive the data. ◦ Interpretation of operand varies depending onop-code
