VLAN ID
The identification of the virtual LAN, which is used by the standard IEEE 802.1Q. Being on 12 bits, it
allows the identification of 4096 VLANs.
VMware
VMware software provides a completely virtualized set of hardware to the guest operating system.
VMware software virtualizes the hardware for a video adapter, a network adapter, and hard disk
adapters. The host provides pass-through drivers for guest USB, serial, and parallel devices. In this way,
VMware virtual machines become highly portable between computers, because every host looks nearly
identical to the guest. In practice, a system administrator can pause operations on a virtual machine
guest, move or copy that guest to another physical computer, and there resume execution exactly at the
point of suspension. Alternately, for enterprise servers, a feature called VMotion allows the migration
of operational guest virtual machines between similar but separate hardware hosts sharing the same
storage. Each of these transitions is completely transparent to any users on the virtual machine at the
time it is being migrated.
VPN model (fixed
path)
The VPN model uses a fixed, more secure path for packet delivery. VPNs only allow authorized
personnel to gain access to their network.

WebDAV
Web-based Distributed Authoring and Versioning (WebDAV) is a set of methods based on the Hypertext
Transfer Protocol (HTTP) that facilitates collaboration between users in editing and managing
documents and files stored on World Wide Web servers. WebDAV was defined in RFC 4918 by a
working group of the Internet Engineering Task Force (IETF).
