  1. Polling
    SW that was written for a specific hardware device constantly runs and occasionally asks the CPU to check this hardware device to see if it needs service
  2. Memory Addresses
    A number assigned to a memory location or cell begining with the number 0
  3. I/O
    input output-are numbers the cpu can use to access hardware devices
  4. DMA
    Direct memory access--a shortcut that let an I/O send data directly to memory. This bypasses the CPU and improves performance
