pNIC (Physical NIC)
what we present to a guest. Our vNICs always appear as wired devices to the guest, even if the pNIC is a wireless device.
vNIC (Virtual NIC)
A method for accessing one computer's filesystem from another computer; not restricted to virtualization. Well-known examples include NFS and SMB/CIFS. Does not require VMware Tools, but does require a network connection.
For example, what you get when you create a new virtual machine with all defaults. A normal virtual machine is portable between computers. Does not have things such as raw disks.
Normal Virtual Machine
A self-contained region of a hard disk that usually contains a filesystem.
A mechanism for setting policies that govern the network connected to it.
A virtual disk where the contents are stored directly on a partition on the physical machine. Not safe to use with snapshots or suspending. For example, a Boot Camp virtual machine uses a raw disk. Contrast with file-based disk.
A division of computing resources used to manage allocations between virtual machines.
The command-line interface for an ESX Server system. It allows administrators to configure the ESX Server system.
service console (can be opened directly on ESX server) If the ESX Server system’s configuration allows Telnet or SSH connections, you can also connect remotely to the service console.
In the context of VMware, a specific method for accessing the host filesystem from the guest using VMware Tools. Does not require a network connection.
Shared Folder (Contrast with network share)
A view mode where the guest's display appears in a single host window. This is the default view in Fusion.
Single Window (Contrast with Unity and fullscreen.)
Symmetric MultiProcessing. Using multiple cores at once.
Virtual Symmetric MultiProcessing. Using multiple cores in one virtual machine.
A way to save all state (disk, RAM, CPU) of a virtual machine (note this does not include network, since that is external). Useful for testing purposes or for remembering a known-good setup.
snapshot (As long as you don't delete the snapshot (or underlying base disks), you can return to this state.)
A (physical) computational unit, e.g. something you would plug a CPU into. Can also refer to a particular type of communication method between programs.
socket (A computer may have multiple sockets, a socket may have multiple cores.)
Automatic ungrab, such as when your mouse leaves the console window
Optional software installed in the guest that improves performance and usability.
tools (Proper name is "VMware Tools")
To direct input (i.e. keyboard and mouse) away from a virtual machine.
ungrab (contrast with grab)
A view mode where guest windows appear to be on the host, e.g. you can interleave them with host windows. Requires VMware Tools; not available for all guests. Contrast with single-window and fullscreen.

workstation (proper name is VMware Workstation)
The actual virtual hard drive for the virtual guest operation system (virtual machine / VM). You can create either dynamic or fixed virtual disks. With dynamic disks, the disks start small and grow as the disk inside the guest OS grows. With fixed disks, the virtual disk and guest OS disk start out at the same (large) disk.
a backup of the virtual machine’s paging file. It will only appear if the virtual machine is running, or if it has crashed.
used to store the exact state of the virtual machine when the snapshot was taken. Using this snapshot, you can then restore your machine to the same state as when the snapshot was taken.
stores information about snapshots (metadata). You’ll notice that the names of these files match the names of the snapshots.
these files are the BIOS for the virtual machine. The VM must know how many hard drives it has and other common BIOS settings. The NVRAM file is where that BIOS information is stored.
the primary configuration file for a virtual machine. When you create a new virtual machine and answer questions about the operating system, disk sizes, and networking, those answers are stored in this file.
A user interface that runs locally in a Windows machine and provides access to the virtual machine’s display. The Virtual Infrastructure Client runs on a networked machine. This can be on the same machine as the VirtualCenter Server or another networked machine. The Virtual Infrastructure Client requires a monitor for access to the virtual machine’s display.
VI Client (Virtual Infrastructure Client)
A file system that is optimized for storing virtual machines.
VMFS File (VMware File System) One VMFS partition is supported per SCSI storage device or SAN. Each version of ESX Server uses a corresponding version of VMFS. For example, VMFS3 was introduced with ESX Server 3.
A high-performance operating system that occupies the virtualization layer and manages most of the physical resources on the hardware, including memory, physical processors, storage, and networking controllers.
A service that acts as a central administrator for VMware servers connected on a network. This service directs actions on the virtual machines and the virtual machine hosts.
