The host that owns the IP address sends an ARP reply message with its physical address. Each host machine maintains a table, called ARP cache, used to convert MAC addresses to IP addresses. Since ARP is a stateless protocol, every time a host gets an ARP reply from another host, even though it has not sent an ARP request for that reply, it accepts that ARP entry and updates its ARP cache. The process of updating a target host’s ARP cache with a forged entry is referred to as poisoning.

The full weekly backup with daily incremental backups strategy results in the shortest backup time during weekdays and uses the least amount of storage space because it only backs up data that has changed since the last backup.
