火线

Firewire是用于数字设备的连接器之一,尤其是在打印机和数码相机中。它是由苹果公司推出的。它具有其他连接器当时不提供的一些非凡功能。在本文中,我们将详细讨论火线连接器。

火线

历史 :
FireWire 连接器在 Apple 注册商标之前最初被称为 IEEE 1394 接口。它是在 1990 年代初开发的。那时,FireWire 提供的速度比任何其他连接器都快。 FireWire 连接器最初是在 Macintosh 计算机上推出的。这种连接器的第一代被称为FireWire 400。后来又出现了多代FireWire 连接器。

世代:

NameYear of ReleasedSpeedDescription
IEEE 1394 (FireWire 400)1995100-400 Mbps          

1. It was a 6-pin connector.

2. It was able to supply power to the connecting devices that means devices that requires small amount of power do not need additional power supply .

3. Its range was limited to 4.5 metres only.

IEEE 1394a2000up to 400 Mbps

1. It was a 4-pin connector.

2. It was unable to supply power to the connecting devices.

3. It was backwards compatible that means all the previous generation is supported as well .

IEEE 1394b (FireWire 800)2002400 MBps1. It was a 9-pin connector.
IEEE 1394c (FireWire S800T)2006800 Mbps1. It uses Cat 5e cable that is basically a twisted pair cable for computer networks.
FireWire S1600 and S320020121.57 Gbps

1. It’s was the last commercially marketed version. 

2. It was backwards compatible.

火线的特点:

  1. 它是可热插拔的,这意味着使用此连接器连接到计算机的设备可以在计算机系统运行时插入和移除。
  2. 它被Windows、Linux、Mac操作系统支持。
  3. FireWire 可以创建对等网络和自组织网络。

火线的缺点:

  1. 所有制造商都不在其设备上包含 FireWire 端口。
  2. 它不能共享系统资源。
  3. USB 比 FireWire 快得多。
  4. 它有一些安全问题。
