(a) Explain Circular wait deadlock.

(b) Explain XSS and CSRF (how do you prevent these attacks).

(c) Fill in the gaps RISC or CISC:

1. Pipelining is less efficient due to instruction complexity and variability ____
2. Emphasis on hardware simplicity and efficiency ____
3. Complex decoding due to variable instruction length ____
4. Each instruction typically executes in a single clock cycle ____
