      Hi everyone!  Welcome to Week 2!

      In week 1, you studied chapters 1 – 3.  You’ve probably noticed that each week, you will have a devotion, discussions, videos to watch, chapters to read, and quizzes/exams to take.  There is so much to learn in such a short time!

      In week 2, you need to study chapters 4 – 5.  You should complete the devotion, discussions, and end-of-chapter exams.  Be sure to read and watch the videos.  

      Most importantly, pray before, during, and after you do your work.  Take Jesus with you everywhere!  

      I like to post devotions from Billy Graham!  Here is one that I love! ~Dr. Anthony

      There is also comfort in mourning, because in the midst of mourning God gives a song. His presence in our lives changes our mourning into song, and that song is a song of comfort. This kind of comfort is the kind which enabled a devout Englishman to look at a deep dark hole in the ground where his home stood before the bombing and say, “I always did want a basement. Now I can jolly well build another house, like I always wanted.” This kind of comfort is the kind which enabled a young minister’s wife in a church near us to teach her Sunday school class of girls on the very day of her husband’s funeral. Her mourning was not the kind which had no hope—it was a mourning of faith in the goodness and wisdom of God; it believed that our heavenly Father makes no mistakes.

      Hello everyone!

      TCP/IP stands for Transmission Control Protocol/Internet Protocol, which is the fundamental communication protocol suit used for transmitting data over networks, including the internet. It basically defines how data should be packaged, addressed, transmitted, routed, and received between computers. TCP ensures reliable and ordered delivery of data by breaking it into smaller packets, checking errors and reassembling it at the destination. The IP on the other hand handles the addressing and routing of these packets to ensure they reach the correct device. Together, it enables different types of computers and networks to communicate effectively, forming the backbone of modern internet communication. Fun fact: its simple and open design has helped make the internet a global network where many different systems can work together with little to no flaw.

        Great job Carlos,

        TCP/IP is still said to be the dominant protocol when it comes to internet standards. UDP is faster, but less reliable according to the lesson. I wonder what other potential protocols might be emerging that could someday surpass TCP/IP as the common standard in the near future?

        Thanks Carlos.

        Your paragraph provides a comprehensive overview of TCP/IP, highlighting its crucial role in modern internet communication. TCP/IP, indeed, forms the backbone of internet communication. This combination allows different types of computers and networks to communicate effectively. Together, TCP and IP enable different types of computers and networks to communicate effectively. This has been instrumental in the growth and development of the internet as a universal platform for communication and information exchange.

      TCP/IP is two separate internet protocols that work in conjunction to ensure data is transferred securely across the network.

      TCP stands for Transmission Control Protocol. This is a communication standard that enables devices to transmit messages. The protocol makes sure that packets are securely sent & received across that network.

      IP stands for Internet Protocol. Since every device that connects to the internet has to be assigned an IP address, this protocol defines how devices and other applications transmit or exchange these packets of information/ data. (What Is TCP/IP in Networking? | Fortinet, n.d.)

        Hello, James! This is a great, concise explanation of how TCP and IP work together as TCP/IP. I also found it quite interesting to learn the differences between the two. Thanks for sharing the reference you used; it does tie in with what we have learned, like UDP, FTP, POP, etc. UDP is an alternative to TCP/IP, but it is not as reliable. Is there a situation that you think would warrant using UDP over TCP/IP?

          Well, from what I’ve read UDP is used in instances where speed is valued over reliability and in instances where an occasional dropped packet would not cause too much concern. A real life application where UDP is used in lieu of TCP/IP would be VOIP phone systems, and also video/online game streaming (TCP Vs UDP: When to Use Which Protocol | Twingate, n.d.).

        Hello James!

        Good post in regards to distinguishing the TCP and Ip and the fact that you were able to highlight the functionality between the two. I’ve been keen into learning Linux and just as i thought, both TCP/IP are native in the kernel. Also, they are heavily used in servers, cloud infrastructure, routers an even firewalls. In essence, any device that connects to a network today uses them and its practically supported by every OS. Also, great reference provided as it was an interesting topic to read.

      TCP/IP contains the protocols from Transmission Control Protocol and Internet Protocol. When exchanging data on a network, there needs to be specified rules concerning how it should be transported, where it is going, and what should happen when a failed data transfer occurs (Yasar, n.d.). Thus, the TCP/IP gives control over these processes to aid in data transmissions and network connections.
      Because we are focusing on TCP and IP in this discussion, I was curious about what the difference between the two are. Although they are grouped together for functionality, there are a few differences. TCP uses a higher-level protocol to run checks to make sure that the connection is working, that the data are transferred in the right order, and that ultimately the data are delivered (Yasar, n.d.). IP delivers the data and makes sure it goes to the right place, but it does not run checks like TCP does (Yasar, n.d.).

      TCP/IP a set of protocols in place for all communication devices. Whenever any data is sent/received they act as rules as to how the exchange is made. TCP is more strict in a sense. It runs specific checks to make sure everything is exchanged in the right order and free of errors so to speak. IP on the other hand, is less “secure” as it only ensure that the data is sent to proper place. It has no checks on the data to make sure that it is exactly as it was sent. Both of these are required for the other to function. TCP ensures the data is whole and free of error, and IP ensures that the data is sent to the proper receiving device. Because every device that connects to the internet at one point or another. Must have these to be able to transfer any data to and from.

        Hi Cameron!
        This is a great explanation of how TCP/IP works and how the two protocols work together. I love how you highlighted some of the differences between the protocols and pointed out that while IP ensures the data gets to the correct location, it does not verify the accuracy of the data. I found it helpful the way you broke that down. Thanks again for a great post!

      Transmission Control Protocol (TCP) is a communication standard that allows application programs and computing devices to exchange messages over a network. It is designed to send information across the internet and ensure the successful delivery of data and messages over networks. TCP organizes data for transmission between a server and a client, guaranteeing the integrity of the communicated data. Before transmitting data, TCP establishes a connection between the source and destination, ensuring the connection remains live until communication begins. It then breaks large amounts of data into smaller packets, maintaining data integrity throughout the process.
      Internet Protocol (IP) is a network layer protocol responsible for addressing and routing packets of data so they can travel across networks and arrive at the correct destination. IP assigns unique addresses to devices on a network and uses these addresses to route packets to their destination.
      TCP ensures reliable and ordered delivery of data between applications on a network, while IP is essential for addressing and routing data across networks to ensure they reach the correct destination.

        Misty,

        I really enjoyed reading your post. While I think we agree on most. I thought your explanation of (IP) to be very helpful in my own understanding. You reinforced the fact that it gives everything a unique address. It is key to understand that fact in my opinion. Obviously, if there are multiples of the same IP then packets of data would find their way to different destinations. Thus leading to the loss or corruption of the data.

        Also, being able to distinguish between the different protocols and how they interact with each other is another point that I really thought was great to mention. Great post and God Bless.

      TCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP/IP is a set of internet protocols that dictate how we send and receive data over a network like the internet. TCP, or Transmission Control Protocol, is the protocol responsible for establishing a connection, breaking the data down (called packets), transferring the data, and reassembling the packets in order once they have reached the destination. TCP is responsible for the reliability of the data sent.

      IP, or Internet Protocol, is responsible for the assignment of distinct network addresses and for routing the packets from one location or device to another. IP works in tandem with TCP. It establishes addresses for each location on the internet, routes packets of information to the proper location, and then delivers the packets of information to the correct destination.

      In essence, TCP handles the breakdown of the data, ensuring reliability, while IP ensures the data reaches the correct destination. Together, these protocols are the backbone of how we communicate online.
