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. 
APOP 
see Authentication Post Office Protocol (APOP) 
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. 
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.
