Network devices have different functions and knowing when to use each one is vital. Three examples of network devices are repeaters, gateways, and bridges. Repeaters (or extenders) are helpful for extending a signal over a greater distance because they take the signal that they receive and retransmit that signal at a higher level. If a company is quite large and needs their network to spread throughout the company buildings, then a repeater could be used to ensure that areas in the company can connect to the same network. A gateway is found where communication paths meet so that the gateway can send the data across different networks. As a result, gateways are used for interactions between different networks and for control of the data that goes across those networks (GeeksforGeeks, 2025a). Bridges connect several LANs to one main LAN by creating different segments (GeeksforGeeks, 2025b). By creating separate collision domains, bridges increase bandwidth to nodes and reduce collisions.

What is Bridge in Computer Network – Types, Uses, Functions & Differences. https://www.geeksforgeeks.org/computer-networks/what-is-bridge-in-computer-network-types-uses-functions-differences/The first thing I would do when troubleshooting is gaining as much information as possible and going from there. Knowing what exactly the issue could be affecting can help to know what steps to take. Learning more about the issue can come from testing the device and asking the user good, clear questions so that they can give information on what they have experienced on their device.
After using this information critically, this should narrow down what the cause could be. From there, I would make a plan and complete the steps of that plan. After taking these steps, I would make sure that the problem has been fixed by running some tests. If it has not been fixed, I would go through the information again and take similar steps to find another solution. If it has been fixed, then I would let the user know what happened and how to prevent the issue in the future, and I would document the issue and what fixed it to keep a record of it.
What Jesus asks is such a personal and necessary question that we all have to address in our lives. Thankfully, it is not related to what others say or even think about Him. It is related to what we say and believe that Jesus is. For me, Jesus is so much; He is my Savior, Friend, Redeemer, and more. It is hard to describe Jesus because He is so big that words cannot really sum up everything about Him. He loves us so much that He came to earth to save us, and just knowing that is amazing. Because of who He is and what He has done for us, we can be in a relationship with Him and be saved and set free. From this, we feel led to worship and serve Him, and even when we fall short, He is gracious enough to help us serve Him as we ask for His help to do so. He is with us every step of the way, and that is amazing.
Hello, Carlos. Nice work on how you presented Standard Operating Procedures and Inventory Management Procedures. After reading your post, I can see how both have their own unique benefits and purposes. In my post, I wrote about safety plans and how incidents are documented. I suppose those would be considered Standard Operating Procedures.
Nice work this course, and I hope you continue and enjoy your journey with Christ as well!
Hi, Carlos. Nice work on your post. I agree that it is good to use the best encryption for keeping Wi-Fi safe from unwanted access. Although the Wi-Fi standard can depend on the speed and range that will be used, the choice for encryption is directly related to the safety of the Wi-Fi.
The first Wi-Fi standards included 802.11a and 802.11b, but eventually 802.11g, 802.11n, and 802.11ac came out as well. 802.11ax is the most recent standard that has been developed, however (GeeksforGeeks, 2021). The standard that should be used depends on what band the standard will be used on and what speed will be needed. 2.4GHz bands can usually reach farther than 5GHz bands, but they are a bit slower (GeeksforGeeks, 2021). However, it is helpful that some of the standards can operate on both bands (GeeksforGeeks, 2021).
There are also a few Wi-Fi encryption standards. First, there is Wired Equivalent Privacy (WEP), which was the original standard and used the RC4 encryption cipher. However, this standard had many problems, so Wi-Fi Protected Access (WPA) was created and used the 802.11i standard. Finally, Wi-Fi Protected Access 2 (WPA2) was the version based on the final 802.11i standard, and it uses the Advanced Encryption Standard (AES) cipher.

GeeksforGeeks. (2021, March 17). Wi-Fi Standards Explained. https://www.geeksforgeeks.org/computer-networks/wi-fi-standards-explained/One procedure that can be incorporated in an organization or business is creating a safety plan. Essentially, this is a plan listing measures for the safety of equipment and people in the organization. Safety typically increases when employees are aware of what to do and not do with certain equipment or situations. Thus, including information about appropriately handling equipment and keeping that equipment grounded is important. Additional information that can be included in the safety plan is a system for reporting injuries, handling/disposing of toxic waste, and any other government regulations that are applicable.
Another important procedure is documenting incidents that occur in the organization. When documenting incidents, keep in mind any requirements from the organization or government. The first step of documenting an incident is creating a description of what happened: who was involved, when did it happen, etc. Then, list its details, such as the cost and violated policies. The next step is related to the resolution of the incident. Report how the response to the incident occurred and whether preparations were made for this situation. After analyzing an incident like this, include ways to prevent it in the future. This could be through creating new rules or policies, teaching employees, or creating a safety plan (or revising it, if it is already implemented).
To answer the devotional’s question, I do consider myself a Christian. Although I try to hate sin and love God deeply, because I am human this can be hard sometimes. I know it is only with God’s help for me or anyone else to be able to do this. To reject sin from coming in us can be hard when our flesh says something contrary to the Spirit. However, we need to hold on to what the Holy Spirit is telling us is right and obey Him. I liked that the devotional mentioned Psalms 50:10. It is a great prayer to God for a change that leads us closer to Him. It does not mean having our heart cleansed is easy, but its reward is more than worth it. Being right with God is most important. Truly having the eternal perspective focused on God helps us focus less on what we want in the present, which is temporary.
I hope you have a great last week of this class, everyone!
Hi, Misty. Nice work on your post. I like that you described how each action helps troubleshoot the printer (or its components). I agree that basic checks are a good place to start, especially if they are able to cover troubleshooting different issues at once. After that, steps specific to issue are usually best.
Hi, Caleb. Nice work with categorizing some troubleshooting methods between software and hardware methods. I agree that deciding which one to start with depends on the issue and that it is always best to start simple and work your way up. This sometimes helps save a lot of time and energy.
When a print is having issues and not printing correctly, there can be many methodologies for fixing those issues. Typically, it is good to start with the simple fixes. Check that the paper is the right type and size, is compatible with the printer, and is loaded correctly. Make sure the cables are securely connected, there is not too much humidity in the room, and that the printer’s power is on.
If it is not related to these issues, it can be helpful to check the software and hardware. Whichever one to look at next depends on the situation. If the problem is with the ink or with ghost images, it is important to check the inkjet print heads, toner, drum, and fuser unit. Problems related to the paper itself may be fixed by checking the feed rollers, paper belt, and paper path. With hardware issues like this, something may need to be fixed or even replaced.
If the user is unable to connect to the printer, there are garbled characters on output, or printer access is denied, it would probably be more helpful to check the software. Ensure the right features are enabled and the right permissions are granted. Additionally, check the operating system and its software programs related to the print. With software, it is important to make sure everything is configured correctly.
Hi, Caleb. Great work on your post. I agree that HDMI and USB are so important for using technology. Their ability to connect devices and peripherals give users a lot of options for which devices they want to work together. Also, the way some of the connectors transmit data can also be helpful for certain applications, like sending information to a printer.
USB connectors, depending on their type, can be used with a variety of devices. For example, USB Type B is commonly used with printers due to the way it transmits data, and a USB mini-B can be used for mobile devices. Micro–USB A is used with digital cameras and cellphones, and micro–USB B is used with on-the-go devices. USB cables can often be chargers by putting them on one end of a cable to be used with an adapter, or they can connect peripherals such as a mouse or keyboard to a computer. Additionally, some devices can be charged with a laptop’s power by connecting to the laptop’s USB port.
HDMI is often used for video, but there are certain devices that the different types of HDMI connectors are used for. A standard HDMI is often used with desktops, monitors, and home theater devices. A micro-HDMI is often used with smaller form factor devices. Finally, a mini-HDMI connector can be used with portable electronic devices.
Like with all troubleshooting, troubleshooting mobile devices involves identifying what the problem is exactly and what is causing it and then taking the next steps to find the solution. These problems could be very general or related to specific features, indicating a software and/or hardware problem.
For general issues, it can often be a wide variety of things. For example, a battery issue could be from problems with the adapter, port, brightness settings, or even the battery itself. If the system is slow or frozen, there might be too many applications running at the same time, there might not be enough storage, or the device might be overheating.
For issues with specific features, there may be problems with the touchpad, display, or speakers. If the touchpad is having issues, check if it is clean, not worn out, and configured correctly in settings. A display problem might be due to damage, display and brightness settings, or power failure. Finally, with speaker problems, first check that the sound is on, then look at the configured settings. If it is on and configured correctly but still not working, it could be a hardware problem.
The focus of this week’s devotional is about John the Baptist and other followers of Jesus and their journey, which for many of them included persecution and death. This can be hard to think about, yet it is very true. However, I think it also points out how important the good news of Jesus and the salvation He brings. This is not something that should affect people slightly. This is life-changing, amazing good news. John the Baptist and many other followers of Jesus showed how much they were committed to Him, no doubt because of how much Jesus did for them and changed them. This commitment came from a relationship with Jesus. In a way, it convicts us by asking us whether we are all the way in with our relationship with God. With God’s help and grace, we can always keep growing our relationship with Him.
