IEEE 1394 and i.Link throughput data speed: 3.2 Gbps A+ Guide to Hardware: pg. 327
3.2 Gbps (gigabits per second) according to A+ Guide to Managing & Maintaining Your Computer - auther Jean Andrews
IEEE 1394 and iLink are other names for fire wire and the speed allowed is 32 Gbps.
IEEE1394 or as Apple calls it, "Firewire" can carry more data. And superior to both of these is Thunderbolt also developed by Apple.

When downstream throughput is higher than upstream throughput, it means that data can be received faster than it can be sent. This can result in delays or bottlenecks as data accumulates waiting to be uploaded. It can also impact the performance of real-time applications that require a balanced flow of data in both directions.
Most pro SLR cameras have a firewire port for quick data transfer of large pictures.
High throughput refers to the ability of a system to process a large amount of data or tasks in a given time period. In data processing systems, high throughput means that the system can handle a high volume of data quickly and efficiently, leading to faster processing speeds and improved overall performance. Essentially, high throughput is crucial for ensuring that data processing systems can handle large workloads effectively and without delays.
FireWire has a higher transfer rate than USB, making it more suitable for video transfer and connecting external storage. USB is host-based, meaningit must have a host computer to transfer data to / from (with a few exceptions). FireWire devices can transfer data between themselves directly without the need for a computer host. FireWire supports fewer devices connected together (63, vs. 127 for USB).
The IEEE 1394 interface was largely developed by Apple and is marketed by them as FireWire.

Outbound throughput simply describes the data bandwidth that a network device can send using. Kinda like a sustained upload speed.
