Have I built and designed the gigabit network at home correctly (see photo)?

Question

Computer networks

I am planning a repair and for this business I want to competently conduct a network in the apartment.
What will happen
1. Internet through a router (at the moment, the speed of the wired connection is 100 Mb/s, the speed of the provider is also 100 Mb/s). If necessary, I will change it to gigabit.
2. Gigabit switch, 2 PCs, network printer, TV, NAS will be connected through it.
3. NAS (it will run a torrent rocker, shared network folders, backups, DLNA).
4. Network printer.
Do I understand correctly that if a switch (1000 Mb/s) is connected to a router (100 Mb/s), then everything connected to the switch will work according to the gigabit scheme, and the router will cut only the Internet?

Answer 1

Yes. That's right

Answer 2

yes. only I doubt, what for NAS is available from a web??? no permanent passwords....

Answer 3

It seems that it is more logical to connect the printer to the NAS server so that it is always available on the network and not when a specific PC is running?

Answer 4

Fixid Alexander Karabanov Kamrady, but explain this nuance: "Won't a 100Mbit router in this case go as the main gateway for all PCs?"
After all, addresses will be distributed from it, therefore, the routing of all traffic will go through it, which means that, in theory, it will not give out higher than 100Mbps. A gigabit switch in this case is not an L3 switch, but simply an L2 switch to which the hardware is connected.

Answer 5

1) According to the scheme you specified, there is no difference. The router and the switch will be one device or different. A gigabit link can also be between two devices (for example, a Router and a PC), if both support it. At the same time, the same router can support a 100Mb link on a different port with a device that does not support Gigabit.
2) Unlike a wired network, wi-fi adjusts to the standard of the slowest device at the moment. For example, if an old G standard laptop is connected to one router, then devices with N or AC wi-fi standards will still work as G. The same situation will happen when you remove an AC or N standard device from the router to such an extent that the connection speed will be faster give G standard. If the network is planned not for an apartment, but for a house, this must be taken into account. It is possible to install another access point separately.
3) If you plan to actively use the NAS, then it might make sense to lay 2 wires from the router to it. Or, to differentiate access from an external and internal network (in the case of a conventional router, one port can be assigned as a DMZ, and the second as a local network), Or for link aggregation, to increase speed. Of course, both the NAS and the switch should be able to do this.
