Toshiba P000233790 MAC Address, Modem registration, Network driver, RJ-45, Subscriber, Subnet

MAC Address

The MAC (Media Access Control) address is a computer’s unique hardware number. When connected to the Internet from your computer, a mapping relates your IP address to your computer’s physical (MAC) address on the LAN.

Modem registration

The process the Toshiba PCX5000 uses to make itself known to the headend equipment. Once authorized by the router, the modem is assigned upstream and downstream channels for data communication.

NAT

Network Address Translation (NAT) is the translation or mapping of an IP address to a different IP address. NAT is used to map several internal IP addresses to a single IP address, thereby sharing a single IP address assigned by the CSP among several computers. Stateful Inspection Network Address Translation (NAT) implementation supports hundreds of pre-defined applications, and protocols.

Network driver

A (software) file included with the Ethernet card. The file is loaded on the computer to allow the computer to recognize the Ethernet card. See Ethernet Card.

RJ-45

Connector on the Toshiba PCX5000, labeled 10/100 that connects the modem to a computer or to a HUB.

Subscriber

A computer user in the home who accesses a data service using the Toshiba PCX5000.

Subnet

A network subdivision. When subnetting is used, the IP (Internet Protocol) address is divided into a subnet number and a host number. Hosts and gateways identify the bits used for the network and subnet number using a subnet mask.

TCP/IP communication stack

Software in the subscriber computer that processes packets through the communication layers. The subscriber configures the IP address for the computer and the router default gateway in the software. The TCP/IP communication stack handles all the communications with the subscriber’s application.

URL

A URL (Uniform Resource Locator) is the address of a file (resource) accessible on the Internet. The type of resource depends on the Internet application protocol. On the Web (which uses the Hypertext Transfer Protocol), an example of a URL is ‘http://www.toshiba.com’.

USB

Universal Serial Bus, standardized for easy connections between the computer and the other peripherals. USB connects more than computers and peripherals.

WEP

WEP is Wired Equivalent Privacy, based on the use of 64-bit or 128-bit keys and the popular RC4 encryption algorithm as described in the IEEE802.11 standard. Wireless devices without a valid WEP key will be excluded from network traffic.
