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.

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.
Hi, James. Great work on your post this week. I like that you mentioned how CDs, DVDs, and USBs function as dual input/output devices. Their ability to interact with computers in this way is a big reason why they are great tools to use with computers.
Hi, Carlos. Great work on your troubleshooting post. I agree that it is important to check on the simpler things first. It is good to avoid a complicated check or replacement of a computer part only to realize it was something simple to fix along. In the end, having a logical order with checking a computer can save a whole lot of time, energy, and even money.
When troubleshooting display devices, it is important to check the power. Ensure the display (and the system it is connected to) has been connected to the power correctly, that the power is safe and reliable, and the cables are in the right places (which can vary by device). Also, make sure the computer is in a good environment; the computer may not function well in a hot place.
Next, complete checks on the hardware and software. See if the issue is with the graphics card or graphics driver, and make sure the components included are compatible with one another. For software, check that the settings are configured correctly, such as resolution, size, and brightness settings or any other type of settings that relate to the issue. Some important tools for troubleshooting and analyzing the hardware and software can be Windows Advanced boot menu (which can boot into Safe Mode), Device Manager, and System Restore (if the situation requires a system restore).
