ADSL - Asymmetric Digital Subscriber Line. The ADSL modem is a device that modulates and demodulates the electrical signal.
Converts digital signals from a computer, into analogue signals transportable via phone line and converting analog signals to decode them back into digital information.
Fast Ethernet (standard IEEE 802.3u)
The Fast Ethernet is the higher technology using Ethernet cables, 100BaseT, allowing 100Mbps rate / maximum speed of transfer.
It is based on the CSMA/CDtechnic, as in the Ethernet standard.
CS - Carrier Sense
MA - Multiple Access
CD - Colision Detection
MA - Multiple Access
CD - Colision Detection
There are several schemes cables that are used:
100 BaseTX - two crossed pairs of high quality
100BaseT4 - four crossed pairs of normal quality
100BaseFX - fiber optic cables
Full DuplexIt allows sending and receiving data simultaneously.
It's the peer-to-peer transmission connection with data collision free , with cables made of copper crossed pairs.
Repeater
Makes the signal stronger and regenerates electrically the transmitted signals in the physical environment.
RouterA router is a devide that forwards the signal on the network with the most appropriate route to its destination.
Makes an interface between the machine or the network, and the global network, formulating an IP only to be viewed at the Internet.
SwitchThis equipment has a similar function to the Hub.
The difference is that the switch segments the network internally, that each door corresponds to a different segment, which means that there will be no collisions between data to send making this device more quick and efficient than the Hub.
HubEquipment that repeats the signal for the entire network.
The Hub connects machines to the same network and can also connect another Hub to this.
Bridge
Device which makes the connection between two networks or simply two segments of the same network.
Sends the information to the address of the package, to the data machine receiver. Suports only for a link between two nodes (machines).
