What protocol maps layer 2 to layer 3 addresses on the TCP IP network?
RARP (Reverse Address Resolution Protocol) maps layer 2 addresses to layer 3 addresses. ARP (Address Resolution Protocol) maps layer 3 addresses to layer 2 addresses.
What is the Layer between the OS and the hardware?
The HAL (hardware abstraction layer) is the layer between the OS and the hardware
Which OSI layer addresses data messages translates logical addresses into actual physical addresses and routes data to addresses on the networks?
Network layer
What type of delivery uses data link layer addresses?
The layer 2 devices use the data link layer addresses.
Which OSI layer addresses data messages translates logical addresses into actual physical address and routes data to addresses on the network?
Network layer
Are network layer address physical or logical?
Layer 3 network addresses are logical addresses and can be easily changed by software.
Which protocol can be used by Router1 to determine the IP address of Router2 when they are directly connected and only layer 2 connectivity exist between them?
Answer = ARPMeaning of ARP - "Address Resolution Protocol", is used to map IP Network addresses to the hardware (Media Access Control sub layer) addresses used by the data link protocol. The ARP protocol operates between the network layer and the data link layer in the Open System Interconnection (OSI) model.
Is the size of ARP packet fixed?
In theory, no, not necessarily, since ARP is flexible enough to be used to discover or describe a connection between other kinds of addresses, which don’t have to be the same lengths as IPv4 and Ethernet addresses.
What is associated with the network layer?
IP addresses
Which layer translates between physical and logical addresses?
Data Link Layer
What layer of the OSI model holds information about MAC addresses?
transport layer
Which layer not support Mac address?
Layer 1 of the OSI Layer Model does not support MAC addresses.
