reception of application-related information in a wireless
communications system
PHY. A PHY chip (called PHYceiver) provides the interface to
Ethernet transmission medium. Its purpose is digital access of
the modulated link (usually used together with an MII-chip).
The PHY defines data rates and transmission method
parameters

transmitting data that does not require acknowledgement from
the recipient of the sent data
Upgrade. To replace existing software or firmware with a
newer version
URL (Universal Resource Locator). The address of a file located
on the Internet
VPN (Virtual Private Network). A computer network that uses
a public network (example: the Internet) to transmit private
