"USB C" is not a protocol. USB-C is a port format.

All Thunderbolt 3 and 4 ports use the USB-C format, but not all USB-C ports are Thunderbolt. Some USB-C ports are USB 2.0. Most are USB 3.0 or better. The majority are USB 3.1 rev 2, which supports 10Mbps. SOME support alt-mode across the port, which allows you to output from that port to video, but some don't.

There are few USB-C ports that support 2x technology, which brings the speed to 20 Gbps across that port. But these are unusual in laptops. Mostly, you'll see this in desktop configurations, provided by an add-on card for a motherboard that doesn't support Thunderbolt.

Bottom line: If you have Thunderbolt (3 or 4) you're pretty much set, but you need to buy Thunderbolt (3 or 4) hubs to take full advantage. if you have a USB-C port (not Thunderbolt), then you're a straggler, and in that case, you can buy the cheap hubs, but you won't' get nearly the feature set for the hub. Most likely (but not guaranteed) your USB-C port will do 10Gbps. It may or may not support power charging your laptop via the port. It may or may not support video via Alt-Mode. All you can be 100% sure of is the physical construction of the port.

    USB 3 connection implies DisplayLink. Max resolution is 1x 4K and 2x 1080p. Your RTX 3080 won't be used for rendering, as this docking station is essentially a USB video card. Won't help with gaming.

CKA Simulator Kubernetes 1.22

  https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
