Finish setup (continued) Ethernet Ethernet cable EWS Gateway HEX host computer Hostname hub IP address MAC address network name NIC RJ-45 connector router SSID switch WEP The most common local network technology that connects computers using copper cabling. The cable used to connect network elements in a wired network. The CAT-5 Ethernet cable is also known as a straight-through cable. When using an Ethernet cable, the network elements must be attached to a router. An Ethernet cable uses an RJ-45 connector. Embedded Web Server. A browser-based utility that provides a simple way to manage the HP Photosmart. You can monitor status, configure HP Photosmart networking parameters, or access HP Photosmart features. A computer or other device, such as a router, that serves as an entrance to the Internet or another network. Hexadecimal. The base 16 numbering system, which uses the digits 0-9 plus the letters A-F. The computer at the center of a network. The TCP/IP name assigned by the installation software to the device. By default, this is the letters HP followed by the last 6 digits of the Media Access Control (MAC) address. No longer commonly used in modern home networks, a hub takes its signal from each computer and sends it to all of the other computers connected to the hub. Hubs are passive; other devices on the network plug into the hub in order to communicate with one another. A hub does not manage the network. A number that uniquely identifies the device on the network. IP addresses are assigned dynamically through DHCP or AutoIP. You can also set up a static IP address, though this is not recommended. Media Access Control (MAC) address that uniquely identifies the HP Photosmart. This is a unique 12-digit identification number assigned to networking hardware for identification. No two pieces of hardware have the same MAC address. The SSID or network name identifies a wireless network. Network Interface Card. A card on your computer that provides an Ethernet connection so that you can connect your computer to a network. The connector on the ends of an Ethernet cable. Although standard Ethernet cable connectors (RJ-45 connectors) look similar to standard telephone cable connectors, they are not interchangeable. An RJ-45 connector is wider and thicker and always has 8 contacts on the end. A phone connector has between 2 and 6 contacts. A router provides a bridge between two or more networks. A router can link a network to the Internet, link two networks and connect both to the Internet, and help secure networks through the use of firewalls and assigning dynamic addresses. A router can also act as a gateway, while a switch cannot. The SSID or network name identifies a wireless network. A switch makes it possible for several users to send information over a network at the same time without slowing each other down. Switches allow different nodes (a network connection point, typically a computer) of a network to communicate directly with one another. Wired Equivalent Privacy (WEP) is a type of encryption used for wireless network security. Connect to a network 51
