Digital Subscriber Line
The most widely used LAN type, also known as IEEE 802.3. The
most common Ethernet networks are 10Base-T, which provide
transmission speeds up to 10 Mbps, usually over unshielded,
twisted-pair wire terminated with RJ-45 connectors. Fast Ethernet
(100Base-T) provides speeds up to 100 Mbps. "Base" means
"baseband technology" and "T" means "twisted pair cable."'
Each Ethernet port has a physical address called the MAC
address. Also see MAC address.
A message generated by a device to inform an operator or the
network management system that something has occurred.
A security software system on a router that enforces an access
control policy between the Internet and the LAN for protection.
Code written onto read-only memory (ROM) or programmable
read-only memory (PROM). Once firmware has been written onto
the ROM or PROM, it is retained even when the device is turned
off. Firmware is upgradeable.
A device that enables communication between networks using
different protocols. See also router.
