Answer:
Option (B) and (C) is the correct option to the following question.
Explanation:
Because the function is the module of the program and we call that function again and again anywhere whenever we need that function in the program.
Function is used to carry out any operation which is used in the program many times and it creates the program short and simple.
<u>For example</u>: if we need to add or multiply two numbers many times in the program then, we create one or two functions for addition and subtraction or one program for both, when we need them we call them.
B = x is equal to 5
and
C = “ have special meaning and should not be used when naming variables “.
Answer:RISC(reduced instruction set computer) is the computer used for low level operation by simple command splited into numerous instructions in single clock only and CISC(Complex instruction set computer) is the computer that performs the operation in single instruction.
RISC architecture has hardwired control unit,data cache unit,data path ,instruction cache and main memory as components .CISC architecture persist of control unit,micro program control memory, cache, instruction and data path and main memory.
The differences between RISC and CISC are as follows:-
- The instruction in RISC are less and and low complexes while CISC has several number of complex instruction.
- The calculation done by RISC are precise and quick whereas CISC has slightly slow calculation processing.
- The execution of RISC is faster as compared to CISC.
- RISC uses hardware component for implementation of instruction because it does not persist its own memory and CISC implements instructions using its own memory unit .
