MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -CISC Processors Architecture The CISC architecture helps reduce program code by embedding multiple operations on each program instruction, which makes the CISC processor more complex.

Detailed explanation-2: -Generally speaking, RISC is seen by many as an improvement over CISC. The argument for RISC over CISC is that having a less complicated set of instructions makes designing a CPU easier, cheaper and quicker.

Detailed explanation-3: -A complex instruction set computer (CISC /ˈsɪsk/) is a computer architecture in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions.

Detailed explanation-4: -CISC are focused more on hardware design while RISC are focused on software design. Hardware design for CISC are difficult and requires a significant investment while for RISC, the investment goes to software development.
