1. emulator 與 simulator

• The Simulator tries to duplicate the behavior of the device.（仿真的是行為）； The Emulator tries to duplicate the inner workings of the device.（仿真的是內部工作原理；）
• An emulator can replace the original for ‘real’ use.（用以“實在”的用途）； A simulator is a model for analysis.（僅用來分析）
  
  • A Virtual PC emulates a PC.
  • If a flight-simulator could transport you from A to B then it would be a flight-emulator.

2. software、hardware 與 firmware

首先需要注意的是，firmware 是一種特殊的軟件。

• firmware（翻譯為固件）：is a special class of software that is not intended to change once shipped（一旦裝載完畢，不再改變）. An update requires either a swap of chips or a special process to reload the flash memory containing the software. This kind of software powers things like your TV, your microwave, and your home router, as well as the BIOS (the boot code) of your PC.
