Address Resolution Protocol (ARP) provides a completely different function to the network than Reverse Address Resolution Protocol (RARP). ARP is used to resolve the Ethernet address of a NIC from an IP address in order to construct an Ethernet packet around an IP data packet. This must happen in order to send any data across the network. Reverse address resolution protocol (RARP) is used for disk less computers to determine their IP address using the network.

Difference between arp protocol and rarp protocol?
ARP (Address Resolution Protocol) is used resolve known IP Address to the Machines MAC Address (Layer 2 - OSI Layer). Whereas RARP is used to resolve IP Adresses from know layer 2 address.ARP is still used while RARP has been replaced with DHCP.
Diskless system uses which protocol arp or rarp?
You have to use both. ARP and RARP cannot be used for the same purpose one gives IP from the MAC address another one MAC address from IP.
What are the function of RARP?
RARP is short from Reverse Address resolution protocol. As the name suggests RARP functions the reverse as ARP. That is it maps MAC address to IP address.
What type of header does an ARP frame contain?
ARP and RARP protocols are present at network layer. ARP is short form of address resolution protocol. IP is the type of header an ARP frame contain .
Can you retrieve a mac address using arp or rarp of a remote server?
Generally, no. 'arp' is only useful for a LAN, and a remote server is not in the same network.
What is the difference between RARP and DHCP protocols?
RARP help the PC to find its MAC address in the same network from the RARP Server.RARP Serveronly providethe IP adress to the PC by remembering its MAC.DHCP works on the same way but DHCP Server provide the PC its IP address, Subnetmask, Default Gateway and DNS Server etc...So the big difference is DHCP provide more information than your RARP Server.
If a device does not know its own IP address can it still use ARP?
No - in order to use ARP it would have to send a broadcast for information with a return address of itself. Since it doesn't have an IP address it cannot do that. Furthermore, without an IP address it couldn't participate on the network.
What type of network would typically require a R ARP service?
Practically, none. BOOTP replaces RARP and DHCP has long since replaced BOOTP. You might have found RARP in use on old UNIX workstations in as late as the early 1990s, but you will never see it in any practical networking situation.
What is ARP and RARP function?
ARP - Address resolution protocol (ARP) enables the packaging of IP data into ethernet packages. It is the system and messaging protocol that is used to find the ethernet (hardware) address from a specific IP number. Without this protocol, the ethernet package could not be generated from the IP package, because the ethernet address could not be determined RARP - Reverse address resolution protocol (RARP) is used to allow a computer without a local permanent data storage media to determine its IP address from its ethernet address.

How is it different than bootp or rarp?
BOOTP is the booting protocol. RARP is the Reverse address resolution protocol.
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.
What does the Data Link layer use to find hosts on a local network?
ARP - Address Resolution Protocoll. Gets the corresponding MAC to an IP. RARP - Reverse Address Resolution Protocoll. Gets the corresponding IP to a MAC. The protocoll uses broadcasts and works only in the local network.
