结构时间轴展开收起

-d6bvS8IX6Q 0:01–1:03 — Everyone has come across a USB (Universal Serial Bus) at some point, but this is just a general name for connecting different devices.
-d6bvS8IX6Q 1:07–2:09 — However, some of these devices now use the new USB-C port.
-d6bvS8IX6Q 2:16–3:21 — USB 3.0 was launched in 2008 and came with a major upgrade of transfer speeds of up to 5 Gbps.
-d6bvS8IX6Q 3:26–4:16 — USB4 offers power delivery of up to 100 watts because it uses the USB-C port.
mdwqZAkYWzQ 0:00–1:01 — Ah yes, USB Type-C, the new USB standard that will save us from constantly trying to put plug in a USB cable the right way.
mdwqZAkYWzQ 1:06–2:09 — It was basically designed to be a more modern, future proof plug.
mdwqZAkYWzQ 2:15–3:23 — This is unlike previous USB cables, where the "host" side, such as your computer, typically had a USB-A connector, and the "device" had some other connector like MicroUSB or USB-B.
mdwqZAkYWzQ 3:25–4:33 — Of course it may also support USB 3.1, but it's not a guarantee. So you need to look at the labelling to see which speed it has.
mdwqZAkYWzQ 4:35–5:37 — This is much higher than the standard 3 amps 60 watts. But again, not all USB-C cables, or devices for that matter, will have it.
mdwqZAkYWzQ 5:42–6:58 — Also, power delivery can take advantage of the "dual role" ability of USB-C, so a port may be used either as a power input or output, or even switch between modes.

字幕依据：Everyone has come across a USB (Universal Serial Bus) at some point, but this is just a general name for connecting different devices. So in today's clip you will find a complete guide to the types of USBs. USB-A is the most popular USB standard and is found at the end of almost every USB cable nowadays. -d6bvS8IX6Q@0:01
字幕依据：However, some of these devices now use the new USB-C port. USB-C can be used in conjunction with Thunderbolt 3 technology, which allows Thunderbolt and USB-C to combine for 40 Gbps bandwidth. In addition to the types of USB connectors we talked about, each USB cable and port has a speed standard. -d6bvS8IX6Q@1:07
字幕依据：USB 3.0 was launched in 2008 and came with a major upgrade of transfer speeds of up to 5 Gbps. USB 3.0 has become USB 3.1 Gen 1, and can be recognized by its blue color and is compatible with previous versions. USB 3.1 was launched in 2013, and the transfer speed can reach up to 10 Gbps and received the label USB 3.1 Gen 2 (Now USB 3.2 Gen2). -d6bvS8IX6Q@2:16
字幕依据：USB4 offers power delivery of up to 100 watts because it uses the USB-C port. It will also allow content display at 8K 60fps resolution with HDR and even at 16K 60fps. Thunderbolt 4 is the next communications standard. The new standard can send 4K video content on two monitors or 8K on one monitor. -d6bvS8IX6Q@3:26
字幕依据：Ah yes, USB Type-C, the new USB standard that will save us from constantly trying to put plug in a USB cable the right way. Most of you have heard of it by now if you're not already using it, but you probably don't know all the details. mdwqZAkYWzQ@0:00
字幕依据：This is unlike previous USB cables, where the "host" side, such as your computer, typically had a USB-A connector, and the "device" had some other connector like MicroUSB or USB-B. So let's get into the different possible speeds of a USB-C cable. mdwqZAkYWzQ@2:15
字幕依据：This is much higher than the standard 3 amps 60 watts. But again, not all USB-C cables, or devices for that matter, will have it. As you can imagine, if the USB-C cable doesn't have power delivery, the most you can get is 3 Amps since that's all the cable is rated for, even if the charger and device do it. mdwqZAkYWzQ@4:35
字幕依据：Also, power delivery can take advantage of the "dual role" ability of USB-C, so a port may be used either as a power input or output, or even switch between modes. This is why in the latest macs, you can charge them by plugging the cable into any of the USB-C ports, and all those ports can also be used to power devices themselves. mdwqZAkYWzQ@5:42
