The architecture of the computer states the hardware and the software of the computer and the hardware of the computer can be anything from the memory, input-output device and CPU and the software of the computer is the application of the computer.

The above question asked about the computer concept, in which the hardware and the software can be studied which is computer architecture which includes the data types and the operation codes as the software part and the register, memory and the device as the hardware part. "architecture " is referred by the option B. Hence it is the correct option while the other is not because--

• Option 'a' states about the layer of the computer which is not detailed about the software and hardware part.
• Option c states about the organization of the computer which is not detailed about the software and hardware part.
• Option d states about the program of the computer which states only the software part of the computer.
