Emulators have grown in popularity recently thanks to their ability to allow one type of computer system to function and behave like another system. What is so amazing about these computer emulators is that they fully act and respond as if you were using another device. Take for example video game console emulators that allow your computer to serve as a Nintendo, Sega Genesis or Game boy. These emulators allow you to play Super Mario Brothers or Sonic the Hedgehog as if you were sitting in front of your television with a control in hand. These video game console emulators function exactly the same as if you were playing the system and allow you to access hundreds of games easily and at a fraction of the cost of what you would pay to purchase the gaming system. Emulators for computers are a function of computer science and can even take the form of hardware devices like DOS-compatible cards. In our directory on computer emulators we will offer up information on the structure of an emulator (memory subsystem, CPU simulator, I/O) and links to emulation versus simulation, logic simulators, functional simulators, terminal emulators and the aforementioned video game console emulators. We will make sure you fully comprehend the importance of emulators for computers and why they are important for consumers and businesses. Our directory will also inform you on the top emulators available and the pros and cons of each so you are prepared when choosing your next emulator.
