To make arp more efficient computers save recognized mac to ip address mappings on their hard disks in a database known as?
To make ARP more efficient computers save recognized mac to IP address mappings on their hard disks in a database known as ARP cache. ARP is an network layer protocol / third layer protocol. ARP provides mapping between Logical to physical address.
Where does the TCP IP host table name system for a local device store a symbolic name to Internet Protocol address mappings?
In a Local hosts file.
What are the functions of ARP?
Address Resolution Protocol (ARP) serves to map IP addresses to their corresponding MAC (Media Access Control) addresses within a local network. When a device needs to communicate with another device on the same network, ARP broadcasts a request packet asking, "Who has this IP address?" The device with the matching IP responds with its MAC address, allowing the original device to establish a direct connection. Additionally, ARP maintains a cache of these mappings to reduce the need for repeated requests, thereby enhancing network efficiency.
What does hosts file contains its a dynamic mapping or static mapping of hostname to ip address?
In UNIX-like operating systems, the /etc/hosts file contains static mappings of hostnames to network addresses.

What does arp -d command do?
The arp -d command is used to delete a specified entry from the ARP (Address Resolution Protocol) table on a computer or network device. This command helps in clearing outdated or incorrect IP-to-MAC address mappings, which can assist in resolving connectivity issues or ensuring that the correct addresses are used in future communications. The command typically requires the specific IP address of the entry to be deleted.
What is a domain server?
Domain Name Servers hold IP address to host name and host name to IP address mappings. For each domain there is usually a primary and secondary Domain Name Server.
What is client side DNS resolver cache?
The client resolver cache is the first place that the DNS client looks for host name resolution. Because it is a location in memory, the client resolver cache resolves IP addresses more quickly than the other host name resolution methods and does not create network traffic. The cache stores host names that have recently been resolved. It also contains mappings that are loaded from the Hosts file. These mappings include the record name, Time-to-Live (TTL) value, and IP address.
Which statements describe characteristics of extended access lists?
They check packets by source address They check packets by destination address
