|
Term
|
Definition
| Sends and recieves signals at different frequencies than the voice band uses. It also connects the computer to the DSL service and it typically connects through the computer's Ethernet port or a USB connection. DSL uses different frequency range, regular phones can interfere unless a seperate DSL line runs in. |

Definition
| Satellite Internet service uses parabolic dish atennnas to send and recieve signals between geosynchrous satellites (approximately 22,000 miles (35,000 km) above Earth. They remain in the same location in the sky all the time. |

Not common, fiber's another alternative. Uses a dedicated line from the ISP to the business or residence, known as point-to-point (PTP) connection since it's not sshared with any other entity's established and it can be fiber to a neighbor boundary and coaxial cable from there or fiber all the way to a business or residence.

Term
|
Definition
| Oldest, consumer-level technology for technology for connecting to the Internet. Uses an analog modem to connect over regular phone lines to an ISP. ISPs that provide dial-up access have several modems and dial-up numbers that their customer can access which are connected via high-speed network trunk lines to the internet. Not that very common anymore. |

Term
| WEP(Wired Equivalent Privacy) |
|
Definition
| First encryption protocol for wireless networks. Uses 64- or 128-bit encryption keys. User only has access to 40 or 64 bits and it was often referred to as 40-bit WEP encryption |
|
|
Term
| WPA(Wi-Fi Protected Access) |
|
Definition
| Developed in part to address certain disadvantages WEP presents. WPA comes with 2 levels of security. WPA-uses TKIP encryption, and WPA2-uses AES encryption. WPA/WPA2 sipports key length up from 8-63 alphanumeric characters, including punctuation marks and character marks aren't permitted with WEP. Also allows RADIUS authentication server to be used in organizations. |

| SSID (Service Set Identifier) |
|
Definition
| Name of the wireless access point's network, and all wireless networks must have an SSID. |
|
|
Term
|
Definition
| Most wireless routers and WAPs allow users to specify the allowable MAC addresses so that only these devices may use the network. The MAC address can be used to block specific MAC addresses from accessing the network. The filters can block casual hackers from gaining access and it's possible to change the MAC Address because they're not encrypted, making them detected by network hacking software. So it's not a full security method. |

Definition
| Virtually all WAPs and wireless routers are configured to act as DHCP servers. |

|
Term
|
Definition
| Short-ranged wireless network technology designed to operate in PTP (Peer-to-Peer), or ad hoc, mode between computers, printers, smartphones, mice, and keyboards. Uses same 2.4 Ghz frequency used by IEEE 802.11 b/g/n networks, but minimizes interference by using sped-spectrum frequency-hopping signaling. |

Term
|
Definition
| Data access plan is purchased from a carrier and it's needed to allow a mobile computer to use a cellular network for data access. They can be connected to USB ports or installed into slots. |
