From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So i tried to connect steamdeck to pc using usb and i read its immpossible because steamdeck is a computer and some explanation on quora about strong master slave relationship. But then why is it possible for android phones to connect to pc whilist also having the ability to use USB and other usb c accesories. Also why cant it be a toggle? So that you can change whetewer this usb( or device ) is reciving data ot sending data .

I'm quite sure that all gigabit+ ethernet auto-negotiates. There is no shared ether, there are no dedicated tx/rx pairs anymore. It's all point-to point and constantly negotiating to make the most of every wire it's got.

Yeah I only learned about that in the comments down below. I was just going off what they taught me when I took my network+ what 3 years ago?

Ethernet being reconditioned to Auto negotiate crossover connections was not covered or if it was it was a blurb and I forgot it in the meantime.

Professional accreditation is such a racket lol. I've seen plenty of tax courses with "the last tax year that so-and-so was relevant was 1988, NEVERTHELESS this will be on the test." Zero effort goes into updating the material, just keep on reselling the same crap to a captive audience forever.

I have taken the A+ certification on two separate occasions and the first time I walked in with no training and aced it. The second time I walked in with no training and I struggled but I still passed.

The CompTIA certifications do get updated on a roughly 3-year cycle, but even so they're never going to cover everything and even if you can pass the test it doesn't actually mean that you are a competent IT person.

Also goes in reverse. Here are probably a lot of good IT specialist who wouldn't pass any comptia test. Not because they are bad IT guys or don't have the necessary skill/knowledge...

No... Just because CompTIA tests are worded in such a way that you actually doubt that every answer could actually be right and fit the question...

They are playing on words and even if you're the best IT guy in the world but lack the reading skills and English collocation of a perfect native Shakespeare writer, you're going to fail ^^.

But that's on purpose 🤑🤑🤑.
