Answer 18

Correct answers: a, b, e

Explanation:

TCP/IP protocol stack consists of 5 layers, as opposed to 7 layers of the OSI stack. They are comparable to their OSI layer counterparts as follows:

TCP/IP           OSI

=======================================================

Physical     <-> Physica

Data-link    <-> Data-link

Internet     <-> Network

Host-to-host <-> Transport

Application  <-> Session, Presentation, and Application

-          Internet Protocol (IP), which resides in the internet/network layer, is a connection-less protocol responsible for routing (path determination).

-          Transport Control Protocol (TCP), which resides in the host-to-host/transport layer, is a connection-oriented protocol based on windowing and aknowledgment. It provides dynamic and reliable data transfer.

-          User Datagram Protocol (UDP), which resides in the host-to-host/transport layer, is a connection-less protocol without windowing and aknowledgment. It provides efficient way of data transfer.

-          Internet Control Message Protocl (ICMP) is a layer 3 (internet/network layer) protocol that provides control and error notification through connection-less messages.

-          Address Resolution Protocol (ARP) is a layer 3 (internet/network layer) protocol that provides MAC address resolution from IP address

-          Reverse Address Resolution Protocol (RARP) is a layer 3 (internet/network layer) protocol that does the opposite of ARP, providing IP address lookup for a known MAC address.
