      Can you explain what TCP/IP is and its purpose?

      TCP/IP is known as Transport Connection Protocol/ Internet Protocol and it’s purpose is to designate the connection between network broadcast addresses, network host addresses, and network user addresses. From what I understand, it works similar to echo location in the wild life but it operates in both directions between network and host. How a bat lets off a soundwave when searching for other bats or prey and the sound wave returns to the bat once it has bounced off of either walls, animals, insects, or whatever the sound wave makes contact with. The bat is then able to designate locations, sizes, and distances from the connections made by the sound wave. In our case, a network broadcaster, host, and user are all communicating through this ping “echo location”. Any information that is recognized as a request from the user ping to the broadcaster. The ping is then returned by the broadcaster through disseminated information, as all connected devices will receive the ping from the broadcaster. If the network host does not recognize the information, it will drop the information there. If the information is recognized, it will push the ping through to the user. If the user device does not recognize the ping, it will drop it and if it does then the request will be accepted. I know this is not a practical way to describe the process and how it TCP/IP works, but it is the closest example I could think of to explain it in my opinion and understanding.

        This is a very interesting analogy! You’ve done a great job of comparing the functionality of TCP/IP to echolocation. It is a very helpful way to understand how information is exchanged within a network. However, I do think that it’s important to remember that TCP/IP is a more complex protocol than simply sending out a signal and waiting for a response. For example, TCP/IP uses a variety of mechanisms to ensure that data is delivered reliably and securely, even if the network is congested or unreliable. But, it is still a helpful way to visualize the process of how information flows within a network.

      TCP/IP is an acronym that stands for transmission control protocol/internet protocol. TCP/IP is a set of protocols that make up the bases of how data is transferred on the internet. TCP/IP can be mostly credited to Vinton Cerf and Bob Kahn for its development. TCP/IP was initially financed by the department of defense to connect research networks. (Yasar & Lutkevich, 2024).

      More specifically the TCP sends information from one device to another in the form of packets. The packets are broken down into smaller packets in sequential order and sent to the recipient. This in turn allows the recipient to reassemble the packets in sequential order while checking for errors or corrupted files. TCP is used for web browsing, email, and FTP.

      After the TCP sends out the data, the IP is responsible for addressing and routing the data to the correct device. IP comes in two main versions IPV4 (32-bit) and IPV6 (128 bit). TCP/IP operates using a four-layer system. The first layer is the link layer. The link layer provides data links between two devices. Next is the internet layer, this layer provides the routing for the data packets. The third layer is the transport layer. The transport layer ensures the packets are delivered efficiently from there the transport layer transmits data from one host to another this includes TCP and UPD. The final layer of the TCP/IP model is the application layer. This layer is what the user uses most. The application layer connects the applications to a network. The application model uses protocols HTTP, FTP, and SSH.

        Hello Trae,

        I noticed in your discussion you referred to TCP as the transport connection protocol, is that a second acronym outside of transmission control protocol? I think you find a creative way to explain TCP/IP I’ve never heard TCP/IP described in that way. I was under the impression that the data was transferred from one packet in sequential order to the next till it reaches its final destination.

          Hi Latoya,

          The words I used for the acronym bare no secondary meanings that I am aware of. While researching information outside of mile2’s provided information. I came across several videos or articles that used one version of the acronym or another, however it is still the same thing. Also, I noticed that everything we do on local networks. Well a Large network is just a combination of smaller networks working together under the same host. If a single device request a task or something and it goes all the way out. On the way back, there are bound to be check points at each level of the data transfer/ request. Another way I can explain is through my experiences as military and as a correctional officer. I can leave the prison and the base as needed or after hours. Even though the security staff knows me, they are still required to follow security protocols and verify who I am.

        This is an informative response to the discussion, I only thought to explain how TCP/IP works. I just thought to explain what I assumed was the method in which TCP/IP operated.

        Thank you for explaining the TCP/IP protocol to me. It’s fascinating to learn how data is transmitted across the internet. I never realized how complex the process was! It’s amazing how all these different layers work together to ensure that information gets delivered accurately and efficiently. I’m glad you broke it down for me in a way that was easy to understand.

      TCP stands for Transmission Control Protocol, and IP stands for Internet Protocol. Both are comprehensive rules and standards that facilitate communication between computers over networks such as the Internet. These protocols enable smooth and reliable data exchange between different devices. TCP/IP defines how data is formatted, addressed, transmitted, routed, and received, ensuring it reaches its intended destination accurately and without errors. As the predominant protocol suite used on the internet today, TCP/IP underpins the fundamental functioning of online communication and data transfer.

      TCP port is Transmission Control Protocol it stands for the ending of communication between two ports they are assigned a number between 0 to 65535. it helps identify the IP address to be able to use and connect with the server and make the connection secure and able to remain secure within the site. It is important to have the TCP/IP to keep from getting viruses and being hacked from outside sources.

        Erin,

        As you explain in your post, I can better understand IP addresses and the importance of keeping them secure. One of the methods of keeping my IP secure is using a VPN, which creates a secure encrypted connection to the internet, effectively masking our IP address.

      TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of protocols that forms the basis for virtually all means of communicating across network devices worldwide on the internet. Simply put, it was designed to facilitate the transmission of information packets reliably on a diverse, decentralized network of interconnected networks. The Transmission Control Protocol (TCP) manages the connection between the endpoints of data sending and receiving to coordinate the negotiations over the reliable delivery of packets between the client and network server. TCP is a reliable protocol that manages error-checking and retrains ensuring the message arrives successfully. Meanwhile, the Internet Protocol (IP) is responsible for addressing the packets and guiding them to the network it occupies and on to the next. It manages how data is packaged, assigning IP addresses to the devices to route it the right way. Together, this TCP/IP protocol suite governs the division, transmission and reassembly of data packets, ensuring that the pieces go where they are meant to go and are received without corruption and in the appropriate order. Ultimately, every activity necessary for using the internet relies on this suite of protocols – whether it is visiting a webpage, sending or receiving emails, securely accessing files, or streaming videos. It is a resilient, world standard process for sharing information in smaller pieces to facilitate the mass exchange of information over great distances and through widely varying network types.
