Two-strand glass fiber cable.
Four-pair twisted copper cable.
Two-pair twisted copper cable for data transmission.
A device that supports autonegotiation functionality automatically
detects the maximum possible data transmission rate and the mode
(half duplex or full duplex) in the network.
Fast Ethernet is specified in the IEEE standard 802.3u and extends 10
Mbps Ethernet to achieve a data transmission rate of 100 Mbps.
In the full duplex mode, a node can send and receive data at the same
time.
The gatekeeper mechanism is a function of virus scanners which
checks every file that is read or written during run time for virus
signatures. Refer to the description of your virus scanner to find out
how to deactivate this functionality.
When operating in the half duplex mode, a node can either only send
or only receive data at any one time. It is not possible to send and
receive at the same time.
