group assignment:send a message between two projects </strong> </p>
<h4 id="introduction" style="border-bottom: 6px solid yellow; background-color: lightgrey" > <strong> Introduction</strong> </h4>
<p style="justify-content: center"><strong> Network communication, or internetworking, defines a set of protocols (that is, rules and standards) that allow application programs to talk with each other without regard
to the hardware and operating systems where they are run. Internetworking allows application programs to communicate independently of their physical network connections. <br>
There are different types of network protocols <br>
•Transmission Control Protocol (TCP):a connection-oriented communications protocol that facilitates the exchange of messages between computing devices in a network. It is the most common protocol in networks that use the
Internet Protocol (IP); together they are sometimes referred to as TCP/IP. <br>
•The Internet Protocol (IP): is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes
the Internet. <br>
•The Hypertext Transfer Protocol (HTTP): is an application protocol for distributed, collaborative, hypermedia information systems.HTTP is the foundation of data communication for the World Wide Web, where hypertext documents
include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser. <br>
•Hyper Text Transfer Protocol Secure (HTTPS): HTTPS is a standard protocol to secure the communication among two computers one using the browser and other fetching data from web server. HTTP is used for transferring data
between the client browser (request) and the web server (response) in the hypertext format, same in case of HTTPS except that the
transferring of data is done in an encrypted format. So it can be said that https thwart hackers from interpretation or modification of data throughout the transfer of packets.
•Ethernet: is the most widely installed local area network (LAN) technology. Ethernet is a link layer protocol in the TCP/IP stack, describing how networked devices can format data for transmission to other network devices on
the same network segment and how to put that data out on the network connection <br>
• Post office Protocol (POP): POP3 is designed for receiving incoming E-mails. etc <br> </strong> </p>
<h4 id="communication" style="border-bottom: 6px solid yellow; background-color: lightgrey" > <strong>Communication </strong> </h4>
<p style="justify-content: center"><strong> Communication between two MCU is called embedded communication.To perform the communication one of the MCU act as a Sender and other to be as a receiver.MCU communications may in one
direction or both, depends on the users choice. There are two types of communication, serial and parallel. The crucial difference between serial and parallel communication is that in serial communication a single communication link
is used to transfer the data from an end to another. As against in parallel communication, multiple parallel links are used that transmits each bit of data simultaneously.<br>
• Serial Communication:In serial communication the data bits are transmitted serially over a common communication link one after the other.Basically it does not allow simultaneous transmission of data because only a single
channel is utilized. Thereby allowing sequential transfer rather than simultaneous transfer. </strong> </p>

<br> <br>
<p style="justify-content: center"><strong> •Parallel Communication:In parallel communication the various data bits are simultaneously transmitted using multiple communication links between sender and receiver.
Here, despite using a single channel between sender and receiver, various links are used and each bit of data is transmitted separately over all the communication link. </strong> </p>

<h4 id="I2C" style="border-bottom: 6px solid yellow; background-color: lightgrey" > <strong>I2C Protocol </strong> </h4>
<p style="justify-content: center"><strong> I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line).
With I2C, we can connect multiple slaves to a single master (like SPI) and we have multiple masters controlling single, or multiple slaves. This is really useful when we want to have more than one microcontroller logging data
to a single memory card or displaying text to a single LCD. </strong> </p>
