What is Firewire?

Firewire, also called IEEE 1394, is a type of connection(connector, cable, port) for external electronic devices, like digital cameras, scanners, printers, external hard drives, etc. Firewire is a brand name that Apple uses to call IEEE 1394, and it is also known as i.LINK by Sony and Lynx by Texas Instruments.

How Does Firewire Work?

Compatible with comprehensive systems, Firewire(IEEE 1394) can work on most Windows, macOS, and Linux systems. The device is hot-swappable and supports plug-and-play, which means you can use it directly without shutting down devices, and the operating system will find the device automatically when it is plugged in. 

Another distinguishing feature of Firewire is that it can work and communicate without a computer, which is very helpful if you want to transfer data from one electronic device to another.

Differences Between Firewire and USB

Firewire and USB are both standard connection types that can be used to connect external devices for transferring data. But they differ greatly in transferring speed, extensive use, and other aspects.
 
As for speed, Firewire supports 800 Mbps, but USB 3.1 now can reach up to 10 Gbps, which is much faster than Firewire. 
 
Regarding usage, Firewire isn't as comprehensive as USB because it is designed for handling data. So most computers aren’t equipped with a Firewire interface. 
 
Another disadvantage of Firewire is its price. Maybe because of its low frequency of use, it is more expensive than USB. 
 
Apart from that, there are a lot of differences between Firewire and USB. If you want to know more, please read this pediaa article, which will explain the difference between the two in terms of designer, length, maximum voltage, maximum current, signal lights, etc.

How to Convert Firewire to USB

Because people use USB far more frequently than Firewire, for some devices that need to use Firewire, we need to convert them into USB interfaces to realize data transmission.

Imagine if you have a camera now and want to import photos to the computer, but the computer does not support the Firewire interface. Using a Firewire to USB adapter at this time can help you finish this task efficiently.

Keep reading the article, and we'll introduce the specific solution to convert Firewire to USB.

The easiest way to convert Firewire is using a Firewire to USB adapter.
