Network interface Card (NIC)
A NIC is a device that handles communication between a device and other devices
on a network.
NVRAM
Non-Volatile Random Access Memory is a type of memory that retains its
contents when power is turned off. One type of NVRAM is SRAM that is made
non-volatile by connecting it to a constant power source such as a battery. Another
type of NVRAM uses EEPROM chips to save its contents when power is turned
off. In this case, NVRAM is composed of a combination of SRAM and EEPROM
chips.
