The UDP protocol is a messaging protocol. Token-based protocols like TCP are known as byte-oriented protocols. Which protocol, UDP or TCP, should an application employ to safeguard the message's boundaries?

Why do HTTP, SMTP, and POP3 use TCP rather than UDP when it comes to communication?

The two main protocols that work at the transport layer are TCP and UDP. Please explain why TCP rather than UDP might be used in the development of a certain application. Give two (2) cases, each distinct.

In HTTP version 1.0, a server marked the end of a transfer by closing the connection. Explain why, in terms of the TCP layer, this was a problem for servers. Find out how HTTP version 1.1 avoids this. How might a general-purpose request/reply protocol address this?

In the Internet of Things (IoT) web stack, what function do the protocols UDP and IPV6 serve? What exactly is the difference between a sensor having a static IP address and one that has a dynamically assigned IP address?

To what extent may the needs of end users be met via the usage of transport protocols? Should all services use TCP, UDP, or both?

Why do HTTP, SMTP, and POP3 use TCP rather than UDP when it comes to communication?

Break down the four abstraction layers that make up TCP/IP.

Please define random access method and identify the two protocols that fall under this umbrella.

ICMP is one of the main protocols of the IP suite. However, ICMP is not associated with any transport layer protocol, such as Transmission Control Protocol (TCP) or User Datagram Protocol (UDP). It is a connectionless protocol, meaning a device does not need to open a connection with the target device before sending a message. This contrasts with TCP, for example, where a connection must be established before a message can be sent, establishing that both devices are ready through a TCP handshake.   ICMP messages are transmitted as datagrams and consist of an IP header that encapsulates the ICMP data. A datagram, much like a packet, is a self-contained independent entity of data. Think of it as a package carrying a piece of a bigger message across the network. ICMP packets are IP packets with ICMP in the IP data portion. ICMP messages also contain the entire IP header from the original message, so the end system knows which packet failed.   How can ICMP packets be misused by an attacker…
