in general, there are a few different types of "foundations" used for housing. you have a raised foundation, where there are concrete posts with wood panels built on top of them. this type of foundation creates the "crawlspace" which can be used to access below the floor. this is a cheap method of building houses, and might be suitable for areas with flooding.

the other type of foundation is a solid concrete slab. this is just as it sounds, and costs more (because concrete expensive) and can be prone to flooding if the water level rises above the slab. but is more sturdy.

so basically, there are devices that

  1. repeats traffic it gets, ie it broadcasts to everyone connected to it, and also used for extending ranges. ie the repeaters and hubs. and range extenders for wireless.
  2. devices that routes traffic to where it needs to go, ie only the specific device connected gets the traffic. ie switches, and access points for wireless.
  3. devices that connect networks together, ie a local area network to a wide area network or two different wide area networks. ie routers
  4. devices that converts one signal format to another signal format, ie analog to digital or digital to analog or coax to wifi, or whatever. . ie modems and transceivers

so basically using the postal service analogy. your post office is a router. all your mail goes through your post office. mail intended for an address not serviced by your post office is delivered to another post office (and that post office figures out where it needs to go). the mail delivery man is like the switch. they connect to your post office (router) and deliver the mail to your door. now a days, hubs/repeaters are typically not used anymore because that's like everyone in your post office delivery area getting everyone's else's mail as well, but you just throw away mail not intended for you.

so typically, tv shows are exclusive to one network or provider. once it goes into syndication, it basically means that other networks buy the rights to air reruns of that show. so it's a way for the original producer of the show to continue to make money. in broadcast tv, they usually have a set schedule of when tv shows air, so they need lots of episodes in order to create a daily/weekly schedule for this show. nowadays with streaming, it doesn't matter as much. any show can be leased to any other streaming provider.

because why does that ikea furniture that comes in a box take up so much more room after you put it together?

same concept. the download is optimized to be small. installing it might require additional space becuase you have to decompress stuff/spread it out (ie laying out the pieces of the furniture in your living room), then you need room to move stuff around and put it together. once you put it together, you can clean up and are left with the installed size (or the furniture).

this is why sometimes when you have 50GB free and the download is 25GB, you can't install it because you don't have enough temporary room for the installer to spread everything out.
