Are switches and routers access devices
A router acts as a gateway to the computer network and is placed between a modem and a switch or hub. A switch connects devices such as a desktop, laptop, and access point to the router. Switches maintain fast local traffic by learning MAC addresses and forwarding frames to the correct port, utilizing VLANs to segment groups. Firewalls enforce security. In the sector of networking, routers, and switches are essential devices that play an important role in facilitating conversation inside and between networks. Wi-Fi 7 can achieve speeds above 40 gigabits per second, though real world performance is likely to be lower.
