A client computer is a personal computer (PC) that accesses the HP Media Vault by the home network. This term also applies to computers using remote access to the server. Also known as the user’s computer.

Common Internet File System (CIFS)

A protocol for how a computer requests files from other computers on the network. This is the public version of the Server Message Block Protocol by IBM and modified by Microsoft. Also see protocol.

## - D -

Digital Living Network Alliance (DLNA)

An alliance of leading companies in consumer electronics. Its purpose is to create industry standards that will allow products from all companies to be compatible with each other and to enable a network of electronic devices in the home.

Digital Media Adapter (DMA), Digital Media Receiver (DMR), Digital Media Player (DMP)

A consumer electronic device that communicates with the HP Media Vault and brings digital media streams—such as photos, music, or video—to your entertainment center.

digital rights management

Technology built into digital media, such as music and movies, that allows companies in charge of their copyrights to decide how and where media can be used.

domain name

A unique name combined with a top level domain (TLD), such as .com or .org, also called a "domain extension," makes up the Internet domain name. For example, hp.com is the Internet domain name for Hewlett-Packard.

Domain Name System (DNS)

A server that associates network names with IP addresses. Also see IP address.

domain extension

A domain extension is an optional part of a network name used to logically divide a large network into smaller networks.

drive partition

A logical division of a hard disk that create the appearance of having separate hard drives for file management, multiple users, or other purposes.

Dynamic Host Configuration Protocol (DHCP)

The protocol used to assign IP addresses to network devices, such as computers. DHCP automatically assigns IP addresses to network devices; the assigned address can change over time. Also see IP address, protocol, and static IP address.

Dynamic IP address

A temporary numeric identification assigned to a node in a TCP/IP network. When computers and devices in the network are turned on, they are assigned an IP address by a DHCP server. Internet service providers typically assign dynamic IP addresses to the Internet connections of their residential and small business customers. Consequently, the IP address to the outside world in a cable or DSL modem may change every month, every day, or even every hour.

## - E -

Ethernet

The standard local area network (LAN) access method for connecting devices to a company or home network as well as to a cable modem or DSL modem for Internet access.

Ethernet Switch

A networking device that connects multiple computers within a Local Area Network (LAN). Switches are similar to hubs, but are more intelligent. Unlike hubs, switches are capable of inspecting data packets as they are received, determining the source and destination computer of that packet, and forwarding it appropriately. By delivering each message only to the computer it was intended for, a switch conserves network bandwidth and generally offers better performance than a hub. Also called a network switch.

Expansion Bay

A slot for adding hard drive storage space to your HP Media Vault.

ext3

A computer file system used in the Linux operating system. HP Media Vault uses the ext3 file system.

top

file system

A way for files to be organized and stored in a computer. Some examples of file systems are FAT32, and NTFS (New Technology File System).

files and settings transfer wizard

A feature in the Windows XP. The Files and Settings Transfer Wizard can transfer files, folders, and settings for Internet Explorer and Outlook Express in addition to desktop and display settings, dial-up connections, and other types of settings to a file on your server. On the new computer, you access this file stored on your server and transfer the settings and files to your new computer.

The HP Media Vault includes functionality that allows media to stream to a Digital Media Adapter (DMA). Also see Digital Media Adapter (DMA), Digital Media Receiver (DMR), Digital Media Player (DMP).

mirror, mirrored

The automatic copying of data on two separate physical disks that creates two separate copies of the same material. If one disk fails, a copy of the material will be available on the other disk.

top

## - N -

NAT (Network Address Translation)

Broadband routers use NAT technology to allow network components to share Internet access over a single IP address. Additionally, NAT acts like a firewall because the computers and other devices—including the HP Media Vault—on the network are given IP address that are non-routable (non-internet addresses). This masks the real IP addresses of your network components and keeps them from being seen outside the home. Also see IP address.

network address

A numeric value that uniquely identifies a device on a network.

network computer

A computer that is connected to other computers, creating a network.

no access

A setting that does not allow a user to access files and folders on the shared network.

personal domain

A personal domain is a Web address. It allows you to access your HP Media Vault and HP Photo Webshare from the Internet. For instance, if you registered `MyFamily.hpshare.net` for your HP Media Vault, you would use this address to connect to your server using remote access. Additionally, this address is part of the URL for accessing an album on your Photo Webshare.

physical hard disk

The actual hard disk (hard drive) located in a device that stores files and data.

port 443

A secure port number required for HTTPS (Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL). SSL uses a 40-bit key size for the encryption algorithm, which is considered an adequate degree of encryption for commercial exchange such as banking transactions and retail commerce.

port forwarding

protocol

The standard(s) of how computers communicate data with each other.

## - S -

Serial ATA (SATA)

Serial Advanced Technology Attachment is an interface standard that moves information to and from a storage device, such as a hard disk.

shared folders

A “shared folder” means the same as a “share,” and you can use these terms interchangeably: A shared folder is a top-level folder that is shared on the network and can store other folders within it. For example, the Music shared folder can store other folders (called sub-folders). A subfolder might be named for a musician, such as Mark Knopfler. Shared folders are sometimes called Shares.

static IP address

## - T -

TCP/IP (Transmission Control Protocol/Internet Protocol)

A set of communications protocols used to transmit data over networks. TCP provides for the establishment of connections and exchanges streams of data. IP specifies the format of the data. Also see IP Address. TCP/IPv4 is the standard protocol in use today. TCP/IPv6 is the standard protocol used by Windows Vista. IPv6 main advantage is the increase in number of available addresses.

UNC identifies shared network devices, such as the HP Media Vault Premier. It is a format for specifying the location of resources on a local-area network (LAN). It identifies each shared resource with a unique address in the following format: `\\server-name\sharedfolder-name`. For example, `\\HPMediaVault\Documents`. Also see Local area network (LAN).

UPnP (Universal Plug and Play)
