VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by
their physical location and can communicate as if a common
broadcast domain, a LAN. The primary utility of using VLAN is
to reduce latency and need for routers, using faster switching
instead. Other VLAN utility includes:

Security, Security is increased with the reduction of
opportunity in eavesdropping on a broadcast network because
data will be switched to only those confidential users within the
VLAN.

Cost Reduction, VLAN can be used to create multiple
broadcast domains, thus eliminating the need of expensive
routers.

802.1Q VLAN, The VLAN tagging option is a standard set by
the IEEE to facilitate the spanning of VLANs across multiple
switches (Reference: IEEE Std 802.1Q-1998 Virtual Bridged
Local Area Networks).

Power over Ethernet (PoE)
Power over Ethernet (PoE) integrates power and data onto one
single cabling infrastructure, eliminating the need to have AC
power available at all locations.
