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.).

With God’s help, I try to be gracious to people, especially because God has been so gracious to me, but even just recently I judged someone who I did not know until God pointed out that I really had no idea about the situation and honestly there was not much evidence even later to say that my thought was correct. In moments like that, the only thing to do is repent, reset, and ask God for help in not being so quick to judge.
Hello, Misty! In your post, there was a network that you mentioned that I did not talk about in my post, which was the Content Delivery Network (CDN). It was great to read about it, and I can see how this would be another great option for network systems. Overall, this was a great overview of the different types of networks.
There are several different categories of networks which have different purposes. A personal area network (PAN) spans a small space, ranging from a few inches or centimeters to a few yards or meters. A local area network (LAN) connects computers in a specified area. This could be used for universities, office buildings, etc. One similar category is the campus area network (CAN), which connects the campus buildings of, for example, a school or university so that all the devices on the campus are connected to the network. To reach an even greater distance, a wide area network (WAN) can go across several cities or even different countries using nodes. A metropolitan area network (MAN) is a type of network that spans across a city or at least part of a city. Finally, a storage area network (SAN) connects storage devices by using network technology. Thus, choosing a network depends on the size of the area that needs the network connection.
Hello, Carlos! I like how you organized the benefits of command lines. It makes sense how command lines are efficient tools, but sometimes it can be hard to word the exact reasons. Although graphical user interfaces can sometimes be easier, the advanced tasks and smaller use of system resources do show the advantages of command line interfaces over graphical user interfaces. Is there a command that you think is used most often or that you use the most?
Command lines allow IT professionals an efficient way to interact with the computer and give it commands by just entering a few lines of text. Some notable functions of command lines include showing information, editing information, and testing connections. To show a list of a computer’s directories, Linux uses the ls command. With commands like these, those in the IT field can gain the information they need. In fact, using the help command in Windows can even help someone to know the commands they are able to use. If someone wants to delete a file or directory in Linux, they must enter rm. This exemplifies the ability to edit information using command lines. Finally, to test a connection in Command Prompt/Windows Powershell, the ping command must be used. Testing a connection is extremely important for deciding what to do based on the results. Thus, command lines are vital tools for managing a computer and computer network.
Forgiveness can be so hard because it feels like unjustly forgetting what someone has done, but it is not about forgetting but rather letting go of the bitterness toward that person. That is freeing and lets us move on. Again, this is in no way easy; it may involve forgiving some people several times a day, but it is done through God’s help and through remembering how much God has forgiven us.
Hello, Carlos! This is a great introduction to some system utilities that are available with operating system applications. I also mentioned File Explorer and Task Manager in my post, which I think just shows how important a lot of these tools are. Also, I like that you mentioned Control Panel because it can take you to so many important settings and controls from security controls to hardware or even to the internet. It is great to have several different groups of options to work with. For anyone in the IT field or even anyone doing something related to it, all of the tools you mentioned are essential.
There are many different types of applications and scenarios that an operating system is useful. If a user wants to connect a computer to a printer, the operating systems lets the computer interact with the printer hardware. Downloading an app like HP’s printer app can further help devices connect to a specific printer.
Operating systems also control the use of files in a system so that they can stay organized. For Windows, these files can easily be seen on File Explorer. There are apps, like Files by Google, that allow you to copy files to your Google Account.
Device Manager is a platform for managing some components of a computer, allowing an IT to analyze what is going on with the computer’s devices through the operating system. When I access my laptop’s Device Manager, it shows several devices and even displays the fact that I have the app Microsoft OneNote installed.
Similarly, using Task Manager allows IT professionals to see what applications are running or are currently using the CPU/Memory. This is important for troubleshooting any issues with the software which would affect the operating system as a whole. For example, if I have the Microsoft Teams app opened, then I could see how much CPU and Memory it is using.
