VR-N100U USERS MANUAL

network.org & a nonprofit organization. There has been a push recently to add more categories for classifying domains.

To transfer data from a remote computer to your computer via a network connection.

A method of defining a pointer to a data storage location, or drive. The letters of the alphabet are used as the pointers, giving you 26 pointers to use to describe specific locations. The first five letters of the alphabet (A through E) are traditionally used to point to local drives (floppy drives, local hard drives, CD-ROM drives). On the network, a drive mapping serves as a bookmark, allowing a user direct access to a particular location. A drive letter is used to represent a logical drive, while a directory path leads to the specific location in the directory structure.

Digital Video (Versatile) Disc, Read Only Memory - A type of read-only optical disc. DVD- ROMs are similar to CD-ROMs in that the data are stored in a laser-generated continuous spiral on the disc surface. The difference is that DVD-ROMs store much more data (4.7GB or more) in smaller pits in tighter circles. Capacity can be increased even more by adding a second layer of pits over the first, and by using both sides of the disc. Experts believe DVD-ROMs will eventually replace CD-ROMs.

The actual rights that a user or group has to access a Camera Set or Individual Camera. Access rights can be granted explicitly, or endowed by inheritance. Admin and users with Manager rights have unrestricted access rights to all Camera Sets and Individual Cameras. While effective rights are cumulative, a user or group needs to be granted access rights by means of only one of these methods (explicit assignment, inheritance, or Manager rights) to effectively access a Camera Set or Individual Camera.

Enhanced Integrated Device (Drive) Electronics - A second generation IDE drive interface that increases the previous maximum drive size. The data transfer rate is speeded up to more than twice that of the IDE. Another name for EIDE is ATAPI.

A standard for connecting computers to a local area network (LAN), Ethernet is the most popular type of LAN. It sends its communications through radiofrequency signals carried by coaxial cable or other media. Developed by Xerox, it is sometimes called IEEE 802.3, which refers to the standard that defines it. The most common form of Ethernet is 10BaseT, which refers to a peak transmission speed of 10Mbps using copper twisted-pair cable.

The physical address of an Ethernet controller board, expressed as a 48-bit number in hexadecimal notation. VR-N100U Ethernet addresses will always take the form 00 80 A1 XX XX XX.

A factory defaults reboot is one of the cycle options associated with the Reset button on the front of the unit. (See Chapter Seven ΠTechnical Tips and Troubleshooting.) The system goes through the preparation for reboot by terminating all network connections, writing outstanding data to the hard drive, and closing all programs. Then, before it begins to start up again, all user configurable parameters (security, user/group lists, server name, etc.) are reset to the settings they were assigned at the factory, the default settings.

See 100BaseT

The software embedded in the nonvolatile memory, flash memory, of the VR-N100U, which can be updated with a new program.

Nonvolatile memory chips that can be reprogrammed with new instructions after the chips have left the factory.

Data is transmitted on the network in blocks and these blocks are encapsulated by headers and trailers that describe where the data came from, where it is going, and the size and integrity of the data. This envelope of information, and the data it encapsulates, is called a packet or frame. Over the years, different frame headers have been defined and used in data communications over local area networks (LANs). Each set of frame headers represents a specific frame type. In order for a device to decode a received frame, it must recognize the frame type used by the sending node. There are four common Ethernet frame types: IEEE802.3, IEEE 802.2, Ethernet II, and Ethernet SNAP. A VR-N100U using the IPX protocol supports all four frame types. A VR- N100U using the IP protocol supports only the Ethernet II frame type.
