IP Address
Series of 4 numbers, all between 0 and 255, uniquely identifying all computer or server connected to theInternet. The user is assigned an address IP by the provider for each connection. 192.168.4.60 could be your IP address for example. There is talk of a fixed IP address when the ISP assigns the subscriber a permanent rather than renew it at regular intervals.
MAC Address
ID card ethernet network. This number is unique: two network cards can not be the same address MAC, Which identifies the sender of a request.
ADSL
The ADSL technology is xDSL that improve the performance of access networks and in particular subscriber line standard telephone network, consisting of copper son. Through the use of two Modems, One placed at the subscriber, the other on the subscriber line, before the Dispatcher Principal, it improves considerably flow network and obtain transmission 70 times faster than a modem Analog classic. The principle of ADSL is to reserve a portion of the bandwidth the transport of voice, another transport data flowing towards the core network (data rising) and the third largest in the transport of data flowing towards the subscriber (downstream data). To correct the return of the voice, filters located at each end of the line remove unnecessary parts of the signal. ADSL technology is particularly well suited to links local loop since it allows the flow decreases with the length of the line. Because of its low cost, it is an interesting solution to benefit from quick access to Internet.
(English: Asymmetrical Digital Subscriber Line)
(French: Line asymmetric Digital)
ADSL2+
L 'ADSL 2 + pushes the limits of copper on the 2.2 MHz frequency up phone lines. Consequently, the flow theoretical maximum reaches 25 Mbps downstream and 1.2 Mbps Issue. However, with ADSL technology, the increasing frequency also determines the signal range. With ADSL 2 +, it is therefore necessary that the telephone is located within two kilometers of the central advantage of rates exceeding 10 Mbps
