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..
Answer:
Operating systems have some code called an 'interrupt handler', which prioritises the interrupts and saves them in a queue. Buffers are used in computers as a temporary memory area, and they are essential in modern computers because hardware devices operate at much slower speeds than the processor.
