Layer 3 means IPs are configured and routing is needed (involved). Redundancy between switches can be done with HSRP or GLBP. Layer 2 are links without IP like trunking and access ports but no routing involved here. Usually means that STP runs here. IP could be used on SVI (interface vlan x) but just to manage switch.Hardware-based Layer 3 switches also use Layer 3 information in forwarding decisions. Layer 3 routers and switches are not concerned whether the packets contain HTTP, FTP, or SMTP data, but simply where the packet is flowing to and from.
