10/100 BaseTX
An Ethernet connection over twisted-pair cables with a throughput of
10 Mb/s or 100 Mb/s.
10BaseT
A 10-Mb/s baseband Ethernet specification using two pairs of twisted-pair
cabling (Category 3, 4, or 5): one pair for transmitting data and the other for
receiving data. 10BaseT (part of the IEEE 802.3 specification) has a distance
limit of approximately 328 feet (100 meters) per segment.
100BaseTX
A 100-Mb/s baseband Fast Ethernet specification using two pairs of either
unshielded twisted pair (UTP) or shielded twisted pair (STP) wiring. The
first pair of wires is used to receive data; the second pair is used to transmit.
To guarantee proper signal timing, a 100BaseTX segment cannot exceed 328
feet (100 meters) in length. 100BaseTX is based on the IEEE 802.3 standard.
Authentication
The process whereby a user or information source proves they are who they
claim to be; in other words, the process of verifying the identity of a user,
device or other entity in a computer system, often as a prerequisite to
allowing access to resources in a system. Authentication is any technique
enabling the receiver to automatically identify and reject messages that have
been altered either deliberately or by channel errors.
See also Encryption and Secure Sockets Layer (SSL).
AppleShare
A file-sharing protocol in Apple system software that allows sharing of files
and network services through a file server in the Apple Macintosh
environment.
Carrier sense
In a local area network (LAN), an ongoing activity of a data station to detect
whether another station is transmitting.
