I must've skipped a paragraph or two. I thought the economy-based network was a pretty neat idea, but you're right, there are definitely a lot of errors...
Yes, but there is downtime due to that? I was under the impression that most lost packets were because of bad checksums, but I guess those would be "corrupted" packets, haha.
There are 3 ways to lose it. First of all, almost all video/audio traffic is sent over UDP. This is because TCP has a lot of overheard/built-in delays, and most audio/video traffic is time sensitive. If UDP gets lost, it's not transmitted. So the 3 ways to lose a packet are: gets lost due to too much traffic, corrupted so checksum fails (as you said), or takes too long (usually there's a threshold, for example any packet that takes over 450ms might be dropped). So yeah, there are many ways. Generally, video is interlaced. That means that each packet contains the data of a few packets before it, compressed more. So you might have:
Packet: [[Frame 4 compressed] [Frame 5 compressed] [Frame 6]]
Packet: [[Frame 5 compressed] [Frame 6 compressed] [Frame 7]]
Packet: [[Frame 6 compressed] [Frame 7 compressed] [Frame 8]]
Of course, the compression is very lossy, which is why it looks crappy when packets get lost. But realistically, audio and video are very tolerant of lost frames.
(can you tell what chapter we're on in Networks class? Go Multimedia Networking!)
Skipped over that paragraph or sentence for sure. I don't even remember reading anything about counterstrike, haha.
Depends what the nanny is browsing.
Side note: shouldn't she be watching the kids?
Yeah, but they give the definite impression that she's not doing anything spectacular. Also, I have never met a nanny, but I doubt they look after kids 24/7. I'm sure they get some time off.
