No - Transport layer protocols are not concerned with addressing packets to the correct system. (True)
ICMP

True
Yes, there is activity; packets do not have to be generated for the sole purpose of carrying data. Some protocols, such as DHCP, or DNS, or ARP generate informational packets and are not carrying data. It is rare for a network to not transmit packets for long periods of time.
The role is to transfer frames to packets
A "protocol" is a set of rules used in networking, for a particular purpose. IP (the Internet Protocol) is the protocol used to transmit packets over various networks.TCP (the Transmission Control Protocol) is the protocol which (among other things) ensures a high degree of reliability over inherently unreliable networks. That is, individual IP packets may be lost, but TCP ensures that they are retransmitted. TCP/IP is a protocol suite - in other words, a group of related protocols. It is named after two important protocols, explained, above, but it actually includes various other protocols as well.
A) people B) transmission and hardware C) protocols and software D) Internet access
routing protocol: helps to find the best path to transfer the packets from one network to diffrent network example: rip: routing information protocol igrp, ospf...... routed protocol: helps to carry the packets to the destination. example: smtp : transfer the mails ftp : transfer the files.
Actually, an IDS does not sit on one particular layer. It has to examine packets for protocols, how they are being transported, number of packets transmitted, spoofing information, and application layer information. In general terms, Intrusion detection system and Intrusion prevention system is a Layer 4 device. It filters for malicious data.
TCP and IP protocols are used for different things. They were developed together and designed to be used together. IP is used for routing purposes. TCP is used for guaranteed reliable delivery (transport). They need each other to get packets from one place to another in a reliable fashion.
Routers may make incorrect forwarding decisions until the network is converged.
