Explanation: CISC means Complete Instruction Set Computer because in this a micro controller has an instruction set that supports many addressing modes for the arithmetic and logical instructions, data transfer and memory accesses instructions. RISC means Reduced Instruction Set Computer because here a micro controller has an instruction set that supports fewer addressing modes for the arithmetic and logical instructions and for data transfer instructions. 7. Give the names of the buses present in a controller for transferring data from one place to another?
A. data bus, address bus
B. data bus
C. data bus, address bus, control bus
D. address bus
Answer:A

Give the names of the buses present in a controller for transferring data from one place to another?
A. data bus, address bus B. data bus C. data bus, address bus, control bus D. address bus
Explanation: There are 3 buses present in a micro controller they are data bus (for carrying data from one place to another), address bus (for carrying the address to which the data will flow) and the control bus (which tells the controller to execute which type of work at that address may be it read or write operation).
