Firmware
Software stored in read-only memory (ROM) or Programmable ROM (PROM). Firmware is often responsible for the behavior of a system when it is first turned on. A typical example would be a monitor program in a system that loads the full operating system from disk or from a network and then passes control to the operating system.
Flash Memory
Sometimes referred as simply "flash", is a compact, solid-state, rewriteable, non-volatile memory device that retains its data when the power is turned off. It offers fast access time, low power consumption, and relative immunity to severe shock or vibration. It is a special type of EEPROM that can be erased and reprogrammed in blocks instead of one byte at a time. Many modern PCs have their BIOS stored on a flash memory chip so that it can easily be updated if necessary. Such a BIOS is sometimes called a flash BIOS.
H
Hardware
The mechanical, magnetic, electronic, and electrical components making up a computer system constitutes its hardware.
Hot Add/Remove
It is the addition/removal of a component while the system is running and operating normally.
L
Link
A connection between any two PCI Express devices is known as a link.
