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.
Forgiveness can be a tough pill to swallow, especially when hurt by someone you loved and trusted deeply. That can be the worst kind of hurt. I used to have trouble with forgiveness, thinking that my forgiveness made the offense ok. I have heard the phrase that forgiveness is like drinking poison and hoping that the other person dies, and this is so true. Unforgiveness is a poison that hinders us in our daily lives and hinders our walk with God. Romans 5:8 sums it up pretty well: “But God demonstrates his own love for us in this: While we were still sinners, Christ died for us” (Holy Bible, NIV). Christ went to the grave to triumph over sin once and for all, while we were still sinners. Knowing this, how can we not forgive others of their transgressions?

Hi Carlos!
Great job explaining the different network classifications! I love how you connected it back to gaming. Are you a gamer? We use a wide area network in my place of employment to connect several local area networks. We have our corporate office in Lancaster, with satellite offices in Hillsboro and Barnesville, as well as network access at each of our substations. This is particularly important in my role as I could be working at any of the locations and will need to have access to everything I would in the corporate office, where I work most of the time.Hi James!
This is a great explanation of some of the commands that can be used with the Command Line Interface. I like how you tied the information back to the specific commands that you use regularly. I have used command line in previous roles, but don’t get to use it as much as I used to. For that reason, I think the help command might be my most used one! I find tracert and ipconfig particularly handy for helping to diagnose network issues.
There are several types of network classifications (or scopes) that are used in various situations. A Local Area Network (LAN) connects a network of devices in a local or limited area. This could apply to schools, homes, or office buildings. Conversely, there are Wide Area Networks (WAN) which span over a large area, possibly in multiple cities, states, or even countries. A Wide Area Network is a type of network that connects Local Area Networks. A Personal Area Network (PAN), as its name implies, is a network that covers a very small area, and is not extremely common anymore.
A few others that you might see are campus area networks (CAN), which connect multiple networks on one campus, such as a college campus or a group of office buildings. A Metropolitan Area Network (MAN), is used like a CAN but connects buildings or areas within a city. Finally, a Storage Area Network (SAN), again, as its name implies, is used to connect storage devices.
The Command Line interface allows you to interact with your computer using text commands as opposed to clicking through the graphical interface (GUI). Command line can be faster than using GUI, and offers more flexibility, but is not necessarily user-friendly.
There are many things that you can do with command line commands. There are commands for file management, as well as disk management. You can add or delete files, as well as directories. You can move files and switch back and forth between directories. There are commands that allow you to create and format partitions, check and repair your hard disk, and even schedule regular scans. You can run scripts and batch files from this prompt. You can display your configuration and ping devices in your network.
The command line interface can be extremely helpful in troubleshooting and diagnosing computer and network issues. The command line interface is a valuable tool when you understand how to use it.
Hello,
This is a great summary of a few popular software applications. You have the standards that have been around forever, such as the Microsoft Office Suite (and even that has changed over the years). I find it interesting how what is going on in society affects the use of some of these software applications. For instance, I had not had much experience with Zoom prior to Covid, but the pandemic and “lockdowns” that followed drove the need for people to find a way to connect.
Software applications run on our operating system and help us accomplish specific tasks. Some common types are Freeware, which is software that is offered for free. Open Source, which allows users to use and modify the code, and licensed software applications or packages that require some sort of license to use.
Much of what I use in my job is commercially licensed software. I have the Microsoft Office Suite installed on my computer at work and use Word, Excel, Teams, and Outlook daily. Another application that I use is Adobe Acrobat. Note that I have Adobe Reader at home, which is a Freeware application. At work, I need the ability to edit PDFs and therefore have a license for Adobe Acrobat.
Additionally, I use applications on my mobile devices. I have an application called AppSuite that I am able to use to access my work tasks if I am out in the field. Additionally, I use my Teams app on my work cell to stay connected when in the field or traveling. I am always a call away from my members (customers) with my Dialpad application that provides me with a desk phone number that will ring to my desk, as well as my cell. These are just a few of the applications that I interact with daily.
