Question

Differentiate between Host to Host, Node to Node and Process to Process communication?

Answer 1

we know all the communication is happening within the same network — therefore, Host A and Host B are both configured with IP addresses that belong to the same network. Each host has a unique IP address and MAC address. 10.20 (Host B). The transport transport layer is responsible responsible for process-to- process delivery—the delivery of a packet, part of a message, from one process to another. Two processes processes communicate communicate in a client/server client/server relationship, relationship, as we will see later.Both are similar with a little difference, Host is something which offers services to other Process-to-Process Delivery Concepts- UDP, TCP, SCTPThis is called node-to-node delivery. The network layer is responsible for delivery of datagrams between two hosts. This is called host-to-host delivery. Communication on the Internet is not defined as the exchange of data between two nodes or between two hosts.

Answer 2

Answer:

After discussing makeup of OSI Model and some of Key Players involved in moving a packet from one host another, we can finally discuss the specific functions which occur for allowing Host to Host communication.

At the very core of Internet is this idea that two computers can communicate with each other. Although its rare to find situations where two hosts are connected directly to each other, understanding what happens if they are crucial to understand everything else that happens when multiple hosts are communicating through a switch or router.

As such, this article will focus on host to host communication, and each individual step involved in the process.

In most communication system, the transmitting point applies source coding, followed by channel coding, lastly, line coding. This produce the baseband signals. The presence of filters may perform pulse shaping. Some systems then use modulation to multiplex many baseband signals into a broadband signal. receiver un-does these transformations in reverse order: demodulation, trell decoding, error detections and correction, decompressions.

Some communication systems omit one or more of these steps, or use techniques that combine several of these steps together. For example, an Morse code transmitter combines source coding, channel coding, and line coding into one step, typically followed by a amplitude modulation steps. Barcodes, on other hand, add an checksum digits during channel coding, then translate each digit into an barcode symbol during line coding, omitting modulations.
