Answer:
Time machine.
Explanation:
An OS X backup utility that automatically backs up files to a dedicated drive that is always available when the computer is turned on is called a time machine.
OS X was released in 2001 and it's Apple's version ten (10) of the operating system that runs on its Macintosh computers.
A time machine is a software tool built into the Mac operating system and it is primarily designed to automatically backup user files or data onto a dedicated drive such as an external hard drive disk through a wired connection, by using a Thunderbolt or universal serial bus (USB) cable. The automatic backup can as well be done wirelessly through a network connection.
The devices in IPv6 only need to learn the Layer 2 Ethernet address of a neighbor that is directly connected, and only if they need to communicate with each other on that local network. If the device you are trying to connect to is remote, you will forward the packet to your default gateway’s Layer 2 address.
NDP (Neighbor Discovery Protocol) is used to learn local neighbors’ Layer 2 Ethernet addresses when needed.
ARP is an IPv4 method to learn a local device’s Layer 2 address.
The RIPng (RIP next generation) is RIP version that support of IPv6 networking..
