PPE is definitely important no matter what field you work in. I’ve had various forms of PPE from time in the military and in healthcare. You never know what is in your environment that could cause you harm. Safety should always be a number one priority.
I agree that WPA2 creates the more secure environment. Standard 802.11ax is a relatively newer standard that wasn’t mentioned in the module. Released in 2019, this standard produces speeds up to 10 Gbps.
Two types of operational procedures are environmental and safety. Environmental procedures are valuable in that they are necessary to prevent hardware from malfunctioning. We need to make sure that hardware is climate controlled and has proper ventilation. Temperature should remain between 65-85 degrees. Humidity needs to be kept between 50%-60%. Failing to meet these standards could lead to condensation, overheating, or static electricity buildup. All of these could be detrimental to hardware. Safety procedures are also very necessary. What is probably the most important safety procedure when it comes to an I.T. environment is that of electrical safety. All electrical equipment should be properly grounded, and PPE should be used when handling electrical equipment. Failure to do so could lead to equipment malfunctions or harm to the user.
This is a topic very similar to that which I have been discussing with my youth group. We have been discussing the responsibility of a Christian to have the integrity to not only do what is right but speak out against what is wrong and evil in the world. The “super-star” pastors do speak on love, but what about speaking out against that which God clearly states as evil? In Genesis 37:2 it says, “This is the history of Jacob. Joseph being seventeen years old, was feeding the flock with his brothers, and the lad was with the sons of Bilha and the sons of Zilpah, his father’s wives; and Joseph brought a bad report of them to his father”. When we look at Joseph, we see a young man of integrity who speaks out against the things which are wrong. Throughout his story, Joseph spends time being sold into slavery, imprisonment, but ultimately though his righteousness and God’s favor, he is promoted to the prime minister of Egypt. The lesson we learn from Joseph is that though in this world we may be unpopular and persecuted for doing what is right, God sees the hearts of all and shows favor on the righteous.
I have noticed throughout these lessons that printers appear to have many more causes for a problem than troubleshooting other devices. I agree with you that a keen eye will go a long way towards identifying issues with printers.
I like that you are very detailed in your responses. You make it clear that you understand all of the troubleshooting information. I have found in mobile devices that damaged charging ports are very common. They tend to bend easily and fill with debris.
The ethernet cable can also be far faster than traditional Wi-Fi depending on what type of cable you are running. Cat6 ethernet can run 1 Gbps. On a funnier note, I had to explain to my church’s youth group what the comp aux options were on the old tv set up in the youth room. They all were confused when they couldn’t find the HDMI cable for the DVD player.
There are currently 6 Wi-Fi standards available today. In order from one to six the standards are 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, and 802.11ax. I did some research, and it appears that there is a Wi-Fi 7 and 8 in development. The encryption standards used for Wi-Fi are WEP, WPS, WPA1 and WPA2. The most commonly used encryption type is WPA2 which also consists of WPA personal and enterprise. WEP is the least common encryption standard due to it having the most issues.
The methodology behind printer troubleshooting is that there could be many causes for one issue. We will look at paper jams as an example. The study guide lists the following as possible causes for a printer to jam, overfilling of paper tray, incorrect loading of paper, paper guides are not properly aligned, problem with the paper, wrong type of paper, different types of paper, and debris caught in the path of paper travel. With printers, there is a laundry list of reasons on why something might be wrong. Eliminating potential causes of the problem is the best way to troubleshoot a printer.
Troubleshooting mobile devices is not so different than PCs. One example is short battery life. Always check to make sure your brightness setting is not maxed out, as this will drain battery quickly. Also make sure you are not running multiple applications simultaneously. This will also drain your battery life. Another example is a malfunctioning speaker. One possible issue is that the sound settings are turned all the way down. Another issue is that the speaker is not configured properly. If neither of those solve the issue, it is possible that the speaker itself has malfunctioned and needs replaced.
There are many different types of connectors for cables. Two of those include straight tip and ferrule connectors. They both are the same size at 2.5mm round. The straight tip uses a bayonet style coupling, whereas the ferrule connector uses a screw. Both have also become less commonly used due to more modernized options.
Christianity is challenging at times. There are moments where we may give in to the flesh or fall short of the standard that Jesus set before us. It is in these moments we need to strengthen ourselves because we are called to share the Gospel. Isaiah 6:8 says, “Also I heard the voice of the Lord, saying: “Whom shall I send, And who will go for Us?” Then I said, “Here am I! Send me”. (NKJV) We need to be like Isaiah and be willing vessels for God to use.
I actually haven’t run into many display issues. I have run into slow response time on an my previous laptop, but that turned out to be corrupt files. I did have a BSOD once that was not recoverable. I agree that staying updated on software will help prevent some issues.
It is interesting how far technology has come. We even have input output devices in cars now. I have a touch screen on my dash that allows me to input commands that change the level of different aspects of my stereo system. Outputs like speakers have also come along way. I was surprised to find out my speakers will produce enough bass to shake my whole car.
