Okay, I know this question sound like a noob question, that is because it is.

Some websites told me a switch connect many devices to the same network, and the switch is connected to the router. But why do people need switches, I mean why can’t they just connect directly to the router? Is the switch just a Ethernet splitter?

Im going to blow your mind. Many routers have switches build in. Mind blown? Ethernet is not like electrical cables, you cant just split it with a spliter. You have to use a Hub or Switch. Hubs are no longer used any more because of limitations they had. Switches allow you to connect multiple Ethernet devices together. For example you have maybe 4 Ethernet devices in your bed room, but your router is in the living room. Are you going to run 4 Ethernet cords, or you can run one to a switch and connect all the devices to a switch. Another reason to use a Switch is if all the ports on your router get filled.

Essentially. Switches are used when there are many ethernet devices need to be connected to the same network. Your average home network won't have need for a switch, but something like an office or LAN center would use one.

I just want to sit back and watch the world burn.

Most routers have at LEAST four ports.

Router:  Quotom-Q555G6-S05 running pfSense WiFi: Zyxel NWA210AX (~940Mbit peak)

Switches: Netgear MS510TXUP, Netgear MS510TXPP, Netgear GS110EMX
ISPs: Zen VDSL (~74Mbit) + VOXI 4G [Vodafone] (~120Mbit) + Three 5G (~500Mbit average)

Most businesses even aggregate all of their users in the switch side.  As above a home router is more often than not a combo device of a router, a switch and a wireless access point.

 

For simplicity's sake most people are just told stuff like 'plug it into the router bro'

Because they have an built in switch. Just because it is built in doesn't mean it's not required.
