No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

I’m going to use some descriptive metaphors to explain this as best I can. Apologies to my fellow Lemmy nerds for the small inaccuracies this might create, but I think I can get the basic point across in plain language.
Bandwidth is how much data can flow over a rate of time. It is similar to a water pipe—a bigger pipe can flow more water into your home, and a smaller one will flow less. If we’re comparing internet data to water, downloading a file is like filling up a bucket until the bucket is full and it is a complete bucket of water. Bigger files are like bigger buckets—you need more water (data) to fill them.
In the case of streaming a video, the bucket has a hole in the bottom because the playing of the video is the equivalent of the water being used and discarded. The flow of data needs to be faster than the play rate of the video (the drain rate of the hole in this case), otherwise the video will pause because it has not received the next section of data to play that video content (the bucket runs out of water). In the 90’s, we all had really small internet “pipes”, so sending data could not happen very quickly, and thus sending video that could be streamed was very difficult (or in many cases, impossible).
Now let’s talk about latency. Internet is unlike a water pipe in that not any old data will do—it has to be that specific data from that specific server.
In plain language, latency is the amount of time it takes to send a signal from a server to your computer and back.
Your computer has to contact that server and tell it “I need YOU to send me water.” The server has to react to that and start sending you the data, but the server has its own pipes to contend with, and it has other requests from other water users it needs to deliver too. If their pipes are slow, or they have too many requests, then the data will not flow to you quickly. If the data does not flow to you quickly, it will not outrun the play rate of the video, and the video will pause.
I hope that helped you gain a basic understanding of these concepts—I did my best. I welcome any other nerds out there to chime in if I misrepresented anything too much.
That means, if l wish to catch up with the live action of FIFA World Cup on the internet, it needs a high bandwidth and high latency. We watch all our TV channels and movies on Jio airfiber, which is an internet connection. It involves very high bandwidth and latency.
Close. High bandwidth, low latency.
High amount of data able to stream, low time to communicate with the server.
That said, servers are a lot faster than they used to be, and video compression has come a long way too, so you can stream more things on a worse connection than you could in the 90’s.
Video compression would be an interesting area to study.
It’s pretty much the entire plot of Silicon Valley (TV show). It is complicated and fascinating.
Can we watch it on YouTube ?
I have no idea, but I don’t think so. It was originally aired on HBO, so I imagine it is on their streaming service.
Or just pirate it like the rest of us.
