固件类型bios和uefi
When a person is just getting into computers, there is a lot of new vocabulary to learn and sometimes it can all get a bit confusing. Take the terms BIOS and Firmware, for instance, do they mean the same thing or are they different? Today’s SuperUser Q&A post comes to the rescue to help a confused reader with terminology.
当一个人刚接触计算机时，有很多新的词汇需要学习，有时甚至会使人感到困惑。 以BIOS和固件为例，它们是同一意思还是不同？ 今天的SuperUser Q＆A帖子旨在为使用术语的困惑读者提供帮助。

答案 (The Answer)
SuperUser contributors malakrsnaslava and Tonny have the answer for us. First up, malakrsnaslava:
超级用户贡献者malakrsnaslava和Tonny为我们找到了答案。 首先，malakrsnaslava：
BIOS is Firmware for computers. As you continue to read and learn about computers, you will gain understanding about BIOS, UEFI, EFI, and so on.
BIOS是计算机的固件。 在继续阅读和学习计算机时，您将了解BIOS，UEFI，EFI等。
BIOS is an acronym for Basic Input/Output System and also known as System BIOS, ROM BIOS, or PC BIOS. It is a type of Firmware used during the booting process (power-on/start up) on IBM PC compatible computers. BIOS Firmware is built into PCs, and it is the first software they run when powered on. The name itself originates from the Basic Input/Output System used in the CP/M operating system in 1975.
BIOS是基本输入/输出系统的缩写，也称为系统BIOS，ROM BIOS或PC BIOS。 它是在IBM PC兼容计算机上的引导过程(开机/启动)期间使用的一种固件。 PC机内置BIOS固件，它是开机时运行的第一个软件。 该名称本身源自1975年在CP / M操作系统中使用的基本输入/输出系统。
Firmware is a combination of persistent memory, program code, and the data stored in it. Typical examples of devices containing Firmware are embedded systems such as traffic lights, consumer appliances, digital watches, computers, computer peripherals, mobile phones, and digital cameras. The Firmware contained in these devices provides the control program for the device.
固件是持久性内存，程序代码以及其中存储的数据的组合。 包含固件的设备的典型示例是嵌入式系统，例如交通信号灯，消费类电器，数字手表，计算机，计算机外围设备，移动电话和数码相机。 这些设备中包含的固件提供设备的控制程序。
Followed by the answer from Tonny:
随后是Tonny的回答：
As others have already stated, BIOS is the specific name for the motherboard Firmware in older PCs. New computers these days have a technically and somewhat different kind of Firmware called UEFI or EFI.
正如其他人已经指出的那样，BIOS是旧PC中主板固件的特定名称。 如今，新计算机具有技术上和某种程度上不同的固件，称为UEFI或EFI。
Please note that any computer will also contain other Firmware (besides BIOS/UEFI/EFI). Network cards, video cards, raid controllers, hard-drives, flash drives, SSDs, and sound cards (just to name a few) can all have Firmware embedded inside.
请注意，任何计算机还将包含其他固件(BIOS / UEFI / EFI除外)。 网卡，视频卡，RAID控制器，硬盘驱动器，闪存驱动器，SSD和声卡(仅举几例)都可以嵌入固件。
Weirdly enough, the Firmware for video cards is often called video BIOS. This is technically incorrect. BIOS is only appropriate for referring to the start up Firmware of the motherboard itself.
奇怪的是，视频卡固件通常称为视频BIOS。 从技术上讲这是不正确的。 BIOS仅适合参考主板本身的启动固件。
