data transmission, 3.1.8-3.1.10

indeed. (fin) sources: my dad

The modem provided by your ISP often includes wifi. Some ISPs provide you with a satellite. or we buy ourself a Wireless Access Point ($20-$50) Your laptop already has a NIC and an antenna to connect. [[sure lets buy a Wireless Access Point, like a pro->buy]]

ASDL is a protocol (like ethernet and wifi) of the vable that your ISP gives you. [[okay->coaxial cable]]

and you've got an ethernet cable! [[now we must do the other side]]

Free Space Optics :LASERS IN SPACE for data transmission nasa bip bop boops. when radio stops working, free space optics got your ~~back~~ data! [[WHOAAAA->reason]]

GO: THE BEST HOME INTERNET $26/month [[pay them]]

You are some guy. You have a litte house with a two ethernet cables, a wireless access point and internet connection. Objectives: ~~1. You must cable your house.~~ ~~2. You must connect to the internet~~ ~~3. You must set up wifi ~~ [[looking good, lets go out]]

You are some guy. You have a litte house with a single ethernet cable and internet connection. Objectives: ~~1. You must cable your house.~~ ~~2. You must connect to the internet~~ [[''3. You must set up wifi'']] [[why would I set up wifi (im lazy!)]] [[how do we define wifi for the exams?]]

A tiny computer that feeds on radio waves >:D Functions as QR codes, scanned by radios and computers: for example boxes factory conveyes belt are more easely scanned for these RFID's. also used to alert thieving in expensive clothing stores. [[we found //that// out by experience->reason]]

Shielded is good if you have a lot of radio interference, so pay a little extra to get rid of it. If you’re on a boat with a huge radar, get the shielded. If you're in a factory, get schielded. Otherwise, you're in your little house in your little office. You're fine. [[got it->copper]]

Switch: A device that forwards packets within the network it is in. related terms are Router (forwards packets from LAN to another network) and Hub (a connection point within a network) [[got it->expand]]

Wimax was a hype in 2010s. ★Long distance wireless ★for a lot of people

Wimax vs LTE (LTE is 2G,3G,LTE,4G,5G) ★Long distance wireless ★for a lot of people LTE is cooler beacause compatible with 2G and 3G on phone. and also WiMAX is dead. [[long live LTE->reason]]

you are very imprecise and it takes you many tries [[but on my 15th try I succeed]]

wireless for a PAN [[connect your headphones->reason]]

step #3: put the arrangement into the CRIMPER [[CRIMP]]

Choose your protocol: (the protocol affects the bandwidth): [[wifi 802.11g 54mbps->wifi plug]] [[wifi 802.11n 600 mbps->wifi plug]] [[wifi 802.11ac 7000 mbps->wifi plug]] Keep in mind the bandwidth will always be less because if ✨interfearance✨

You now have some cables! (set: $ethernet to true) you also bought some wirecutters, RJ-45s, and a crimper. [[go home and get ethernetting!]]

used for TV! Rather than etheret, used for [[ASDL]] [[that doesn't concern us, we are doing ethernet->go cable shopping]]

Type in wifi name: (input-box:"XXXXXXXXXX=========",1) Type in network password: (input-box:"XXXXXXXXXX=========",1) [[done!->reason]]

Unlike your ethernet, Wireless needs security because anyone within range can try to connect. [[cofigure network]]

CABLES: type 6A: 10 gbps, $3/m type 6: 1 gbps, $2/m type 5: 100 mbps, $1/m Because it's ethernet, you dont need terminators because they go from laptop to router/switch, and the laptop has an in-built Network Interface Card (NIC) THERE ARE ALSO [[SHIELDED AND UNSHIELDED]]! [[hmmm...->go cable shopping]]

you have cut some ethernet cable. step #2. you put wires into the RJ-45 (connector). [[arrange]]

ethernet is ☆ a physical-level protocol ☆!! A copper twisted pair (could be fibre optic if you want to go fancy) is used for ethernet. Before, [[coaxial cable]] was also used. [[got it->go cable shopping]]

You would need to connect a [[Switch]] to your modem. [[later->plug]]

fibre optic category: ☆10 terabits $1/m ☆$50 per terminator, so $100 per cable (2 ends) [[what and why terminators]] [[why fibre optic]] Note: Installing fibre optic super expensive because its glass! if you break it you need to get special instruments to fix it. buy tools :(. [[hmmm...->go cable shopping]]

you are $treat while you're connected to the free wifi. It is nothing compared to your lavishness at home. [[why is it soooo slow->you wonder why]]

you are at The Cable Shop Near You (tm)(set: $cable to '') (set: $ethernet to false) you need to buy yourself an [[ethernet ]] cable. [[fibre optic]] [[copper twisted pairs->copper]] [[coaxial cable]] [[LEAVE->home]] [[place order]]

to create an ethernet cable, you must step #1. cut cable the right length enter the length of cm you want to cut: (input-box:"XXXXX==============",1) [[cut]]

the lamp glows orange against the dark blue street. we want to share it with... (input-box:"XXXXXXXXXX=========",1) [[yeah, that person!]]

you want to connect your devices and have internet, don't you and... - wireless is shared medium with finite capacity, however everyone connected to ethernet can use the max bandwidth. (link-reveal: "Got it")[] -cable is less susceptible to interference (but not immune to), thus has consistent speed and lower latency. (link-reveal: "Got it")[] - more secure because physical connection is harder to intercept and thus no need to encrypt. (link-reveal: "Got it")[] - cover long distances without loss of signal (like between malta and sicily!)(link-reveal: "Got it")[] [[home]]

You are some guy. You have an empty litte house. Objectives: ''1. You must cable your house. ''2. You must set up wifi 2. You must connect to the internet [[go cable shopping]] [[hold on, why would I want to cable my house]]

You are some guy. You have a litte house with a single ethernet cable. Objectives: ~~1. You must cable your house.~~ ''2. You must connect to the internet ''3. You must set up wifi [[Find an internet provider]]

wifi is a protocol to send data through radio waves just like ethernet is protocol to send data through cables [[i see!->Home3]]

In your TV remote used before for network connection but now we have wifi. [[interesting->reason]]

you go out to treat youself to some(set: $treat to "") (link: "chicken nuggets")[\ (set: $treat to "munching on some chicken nuggets")\ (go-to: "free")\ ] (link: "coffee")[\ [(set: $treat to "sipping on coffee")]\ (go-to: "free")\ ]

A modem converts analog signals in wires to digital data that your netwrok can unserstand (and back) [[got it->pay them]]

Microwaves and wifi use the same frequency!! microwave is 2-5 gigahertz and wifi is 2.4, 5 and 6 ghz. (we learned this in IGSCE, the 6 ghz is the brand new one) Your wifi won't work whenever the microwave's working. [[FINE ill place it somewhere reasonable IF YOU INSIST->configure]]

you are a broke college student. [[oh->place order]]

Good choice! microwave is 2-5 gigahertz and wifi is 2.4, 5 and 6 ghz. (we learned this in IGSCE, the 6 ghz is the brand new one) Your wifi and mocrowave will be able to coexsit in peace. [[im so smart!->configure]]

its done! [[now what->home 2]]?

GO gives you a fibre optic cable (or a coaxial cable) and a [[modem]]. [[plug in your laptop with your ethernet->plug]]

where do we place our Wireless Access Point [[next to the microwave]] [[not next to the microwave]]

I want a... [[twisted pair type 6A->checkout]][(set: $cable to 'twist')] [[twisted pair type 6->checkout]][(set: $cable to 'twist')] [[twisted pair type 5->checkout]][(set: $cable to 'twist')] [[fibre optic 10 terabits->no you dont]] [[wait go back, what do these options mean again?->go cable shopping]]

1/4 nodes occupied [[expand]]. [[done->Home3]]

Hmmm we've got wifi, but what other wireless options exist? You see, there is Microwaves (which are a frequency of radiowaves), but other wireless protols we also have ★ [[bluetooth]] ★ [[RFID]] ★ [[satellite]] long distance wireless protocols:[[Wimax and LTE]] and then beyond the radiowave spectrum, you've got ★ [[infrared!]] ★ [[FREE SPACE OPTICS!]] [[okayyy thats enough!!->Home 4]]

some ISPs instead of cable let you connect to satellite. easy access slower speeds $200/month [[interesting->reason]]

You trot along the street back home contemplating your life choices. [[but at least I have my own little network at home-> end]]

[[plug your Wireless Access Point in->place]]

You will need to buy additional terminators because you need a terminator/modem to translate the fibre optics light signals for your computer to understand. [[ouch->fibre optic]]

high speed long ditsnace internet! when it's used for low distance, its typically for supercomputers ISPs may use fibre optics connected to hubs to distribute internet. But you may use it short distance in your office, who is to say that you can't. [[got it->fibre optic]]

✰ you are free to move! isnt it nice to not trip up on cables? (link-reveal: "It is nice!")[] ✰It is easily expanded! no need for all that cabling. It was a lot of work, wasn't it? (link-reveal: "It was...")[] [[I see->Home3]]

you got a Wireless Access Point! you need to make another ethernet cable to plug it into your modem [[ugh]]

you want some wireless connection, too! which to pick... [[radio waves]] [[microwaves]] [[wireless

as you hit 'send', your phone compresses the image to reduce bandwidth usage and network congestion. [[that's nice]]

- netwrok traffic (link-reveal: "how dare other people use it")[] - time of day (link-reveal: "it is 8pm and so crowded")[] - interfearence (link-reveal: "i see you, microwave >:(")[] - maybe dont stream that 4K movie on your phone on free wifi (link-reveal: "fine")[] [[go outside and take a picture of the lamp]]
