解密固件 [英] Demistifying Firmware

问题描述

固件-这到底是什么?我知道这不是一段代码，因为它是设备驱动程序的功能，因此仅有助于与硬件通信.

Firmware - What exactly is this? I know that it isn't a piece of code which just helps in communicating with the hardware since it is the device driver's function.

我想这要复杂得多.一直以来，我都看到mp3播放器和智能手机的固件更新.在智能手机中，我看到在固件更新后，操作系统的版本出现了问题，例如从Ice Cream Sandwich转到了Jelly Bean(Android).这是否意味着固件是OS的别名?

I guess it is something more complex than that. All the time I see firmware updates for my mp3 players and smartphone. In smartphones I see that after a firmware update the OS's version is bumped up e.g., from Ice Cream Sandwich it goes to Jelly Bean (Android). Does this mean that firmware is an alias to OS?

推荐答案

固件只是编程到设备中的软件.在您使用的示例中，操作系统可以称为固件.在其他设备中，它可能不如iOS或Android复杂，例如，许多DVD播放器和Blueray播放器都具有固件组件，例如具有Internet功能的智能电视和路由器也是如此.

Firmware is just software that is programmed into a device. In the example you used, the OS would qualify being called firmware. In other devices, it could be less sophisticated than iOS or Android, for example, a lot of DVD players and Blueray players have a firmware component, so do smart TV that are Internet enabled and routers, for instance.
