The well-known crack of a rifle, whose ball came skipping along the placid surface of the strait, and a shrill yell from the island, interrupted his speech, and announced that their passage was discovered.
An arc fault circuit interrupter (AFCI) is a circuit breaker that breaks the circuit when it detects an electric arc in the circuit it protects to prevent electrical fires. An AFCI selectively distinguishes between a harmless arc (incidental to normal operation of switches, plugs, and brushed motors), and a potentially dangerous arc (that can occur, for example, in a lamp cord which has a broken conductor).
AHCI (Advanced Host Controller Interface) An AHCI (Advanced Host Controller Interface) is a hardware mechanism that allows software to communicate with Serial ATA (SATA) devices. AHCI enables the use of advanced features, such as hot swapping and Native Command Queuing. Hard drives using AHCI mode can operate at higher speeds than those in Integrated Drive Electronics (IDE) mode.
