Access, Distribution, and Core Layers Explained
Switches in this layer are called access switches. End devices connect to the LAN through the access switches. In other words, an access switch forwards traffic between connected

Core Switch vs. Distribution Switch vs. Access Switch
The access switch is the network switch that connects the access layer with the subnets. The subnets are integrated with access devices like routers, IP devices, control, and monitoring panels, etc.

Class notes and links
In Ethernet the RG8 (thick wire) cable is connected via a vampire tap MAU (media access unit). In Ethernet with RG58 (thin wire) a BNC T connector is used to connect to the MAU.
