|
HEX | Hexadecimal. The base 16 numbering system, which uses the |
| digits |
hub | No longer used much 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. |
IP address | 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. |
infrastructure | An infrastructure network uses a router, switch, or access point |
| to connect network elements. |
MAC address | Media Access Control (MAC) address that uniquely identifies |
| the HP |
| assigned to networking hardware for identification. No two |
| pieces of hardware have the same MAC address. |
NIC | 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 |
| similar to standard telephone cable connectors, they are not |
| interchangeable. An |
| always has 8 contacts on the end. A phone connector has |
| between 2 and 6 contacts. |
SSID | Service Set Identifier. A unique identifier (up to 32 characters) |
| that differentiates one wireless local area network (WLAN) from |
| another. The SSID is also referred to as the network name. This |
| is the name of the network to which the HP |
| connected. |
router | 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. |
switch | 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. |
