MMU, RISC+CISC, Arbitrary Code, Multitasking

Question 1

Memory Management Unit (MMU)

Answer 1

Handles address translation
Checks for access permissions

Question 2

Reduced Instruction Set Computer (RISC)

Answer 2

Focused on software/compiler to handle efficient register usage
1 instruction per code
Register-to-register design

Question 3

Complex Instruction Set Computer (CISC)

Answer 3

Focused on hardware and is easy to program
Several clocks per instruction
Memory-to-memory design

Question 4

Arbitrary code

Answer 4

Allows attacks to insert code into a system

Question 5

Multitasking

Answer 5

Running multiple tasks at the same time, and minimizes waiting time

Question 6

Time sharing

Answer 6

The processor switches between different tasks

Question 7

Direct Memory Access (DMA)

Answer 7

Transfers data between PC components without the need of the CPU

Question 8

Principle of locality

Answer 8

Memory access tend to be together, instructions are ordered, and data is likely local
