Nicely done Caleb,
Operational procedures are vital for any organization to run effectively. Whether a small business or a large corporation one thing is for certain, if there is no organization or structure, no clearly defined plan or procedure to handle even the simplest tasks, things can go awry. You can work at McDonalds, there is a repetitious procedure for how to make a Big Mac. Two all beef patties, special sauce, lettuce cheese, etc. You get the point. But any employee that works there should know how to make a Big Mac, because it is done the same way every time. If you don’t have plans or procedures it leaves room for error. People can get hurt, or equipment can get broken, or quality will degrade, the list goes on and on.
Great post Teisha.
It is interesting to see how Wi-Fi 8 will be now that we have Wi-Fi 7 and 6GHz frequency bands available. Also with the introduction of WPA 3 it is said to encrypt every device on the network with an individual encryption key. It is truly fascinating how far technology has come just since Y2K.
Two standard operation procedures any company or organization can use are Safety Plans and SOP for Professionalism. A fully inclusive safety plan protects both the employees as well as the company’s equipment. Proper documentation providing safety procedures for employees to follow warrant all employees are adequately trained. Refresher training, sometimes called continuing education credits, should be offered on a consistent basis to ensure that employees are always at the forefront of their trade. Some components that should be included within a safety plan are PPE or personal protective equipment, such as googles, earplugs for loud noise environments, face masks and gloves. Whatever the guidelines for certain companies may require. Equipment grounding to prevent electrocution or shock to employees and prevent loss or damage to high-value equipment.
Incident reports or an incident reporting system to document any equipment malfunctions, hardware or software related, health and safety violations, human error or negligence as well as criminal behavior or activity that may arise. It is important to communicate incident reporting should include how to respond to certain incidents, such as when to administer CPR, defibrillator training, how and when to use eye wash stations, etc. securing equipment in the event of a break in, or sealing off the area in the event of loss of life, and it is equally as important to have documentation procedures in place as well. Toxic waste handling and disposal if needed, material data safety sheets for chemicals and supplies that may be hazardous, and any other compliances needed for federal, state and local requirements.
When it comes to Standard operation procedures for professionalism you simply want to outline how to adequately demonstrate things you should already know. Show up on time, use appropriate language, proper attitude, no negative complaining about the company, or the client. Execute your soft skills and minimize anything that would present yourself or your company in a negative perspective. Value can be found on a corporate level or at a small business level when implementing both of these SOPs. It confirms observance to best practices and maintain consistency within the company operations, which provides optimal productivity and reduced errors.As we move further into 2025 Wi-Fi standards are progressing quicker. Wi-Fi was originally introduced in 1999 as 802.11b which would be considered Wi-Fi 1 now with a 2.4GHz bandwidth and 11Mbps or Megabits per second. Since that time we have been introduced to 802.11 a, g, n, b, ac, ax, axe, and now be in Wi-Fi 7. They are basically the standards or rules set forth to govern wireless communication over networks put together by the Institute of Electrical and Electronics Engineers or IEEE. They continue to revise these standards since, like most electronics, advancements in speed, range, device capacity, frequency bands, and security continue to evolve. I would say most people are commonly operating on Wi-Fi 5 standards right now, but Wi-Fi 6, 6E, and Wi-Fi 7 are rapidly pushing in to the market and as people upgrade, they will eventually take over. As for encryption standards, wireless networks began with WEP, which quickly identified as highly vulnerable to cracking the encryption keys, from there WPA, then WPA2, which has been the standard for some time, but is now giving way to WPA3.
Nice job Carlos,
The thing that stood out to me most about your post is the software side of printer troubleshooting. I work as a technical support analyst for printers and in many instances, the issue is a tray is set to the wrong size for the stock that is inside, which will cause jams. Also overfilling trays can cause jams. Many of these issues can be easily resolved if the users took time to read the solution on the screen. Many printers and models are only rated to work with specific paper stock weights and thickness like 20 lb stock is your standard plain paper for printers versus 90 or 110 lb is considered cardstock and is used for specialty printing like post cards, brochures, etc. These can cause issues also, but a lot of issues are user error before it ever gets to the service level of repair.
Hey Isabelle,
Good job giving a brief description on various issues you may troubleshoot on mobile devices. Glad you took the time to mention these issues can be software or hardware related, and then went on to give examples such as the battery where it can be something like the charging port, or something like a brightness issue. Sometimes having the brightness too high causes the battery to charge and discharge irregularly and lead to the battery swelling or loosing the ability to charge without the power cord being plugged in. Excellent work.
Great job Teisha,
Good explanation of the instances in which each type should be used. As you pointed out STP is best used in instances where you want to maintain signal strength and prevent interference over distance. The networking environment for each project is key to determining which type of cabling is needed.
So the book says vacuum out dust and debris, clean the toner cartridge head, corona wires, internal fans, clean and replace pick, separator & feed rollers, replace maintenance kits at designated intervals, and calibrate printheads & registration as needed.
My first job right out of college was working for a thermal transfer printer company. Obviously you want to clean out all machines, but the primary components that needed serviced on these were cleaning & replacing the printheads, they would wear on the edges where the rolls of thermal labels & stock would rub against the printhead directly in areas the ribbon did not cover. Other than that they were solid built devices with not too much else that went wrong with them aside from board level repair & flashing or replacing the EEPROMS. Inkjet printers need printheads cleaned and make sure nozzles don’t get clogged.
I worked as a laser printer technician for several years afterward. Most of the laser printers serviced today have heating lamp now, but some larger laser printers that print 90 plus pages a minute may still use corona wires, which I do have experience cleaning as well & then using setting powder before reinserting in the fusing belt/ roller. They definitely need cleaned and vacuumed out regularly. The photoconductors (drum), cleaning blade, charge rollers, can be cleaned, however most manufacturers opt to swap them out as an all-in-one unit. Fans are important to clean as they may cause overheating if clogged with dust & debris. But changing feed rollers at the designated time interval is a must. Like getting oil changed on a car, if you don’t replace certain components after 200K copies, etc, you may run into many problems. Most printer manufacturers have product support guides which tell you how long components are rated to last; 30K copies, 100K, 300K, like cars tell you how often to rotate tires, change oil, spark plugs and so on.
This discussion can be tricky because there are so many different mobile devices and proprietary methods for troubleshooting certain issues, however the common issues would be no power, blank displays, freezing or hanging up, memory issues, and more. many mobile devices need replacement components to resolve these issues such as removing the battery, replacing the memory, some mobile devices allow for the upgrading of physical storage while others do not. If it is a laptop, sometimes you can replace the keyboard or touchscreen should your troubleshooting for blank display lead you to replacing the display. Many instances it can be resolved simply by finding the upgrading the graphics driver or graphics card.
Based on the cable connectors discussed in chapter 9, two types of cable connectors would be Twisted Pair cable connectors and coaxial cable connectors. The two most common types of twisted pair connectors are UTP, which is unshielded twisted pair and STP, shielded twisted pair. They are commonly used in network cable or wiring such as CAT5, CAT6, and CAT7 with RJ45 connectors. It is also used in telephone wires with RJ11 connectors. Coaxial cable consist of a copper conductor wire used to send the electronic signal, a flexible plastic layer used as an insulator for the copper wire, then a braided copper or thin foil layer used as the second wire and shield for the insulator, followed up by the final layer which is the jacket, a rubber layer that acts as the deterrent for any damage for the previous three internal layers. These are commonly used with RG-11l or F-Type connectors for cable modems.
John the Baptist was the forerunner for Jesus Christ. He was sent to prepare the way of the Lord. I love the fact that he preached the gospel with truth and conviction. He didn’t have any issue standing up against for justice in his day, which eventually cost him his life. The devotion reminded me of Mark 10:29-30 which to paraphrase in a nutshell Jesus is saying anything we sacrifice in this life in service or devotion to the Lord’s work we will receive back multiplied in this time, with persecution, and eternal life in the world to come(James, 2019). We may not physically have to walk away from our immediate family, but we may have to walk away from their belief system to take on God’s.
John responded with bravery, but while he was imprisoned awaiting beheading he sent word by his disciples to Jesus saying, “are you He that should come, or should we look for another?” asking if Christ really was the promised Messiah (James, 2019; Matt. 11:3,KJV). When things got hard, even though John knew Jesus was the Messiah, his faith did waver. The beauty is that Jesus didn’t cast him aside because he wavered. He told his disciples to look at what they saw & heard with their own eyes & ears from Jesus. Then go back, report & tell John God blesses those who are not offended of Him, meaning don’t turn back because of the trouble you might have to endure. So I believe John stayed the course because of this reassurance from Jesus in the midst of a difficult circumstance. This is encouragement to me as well knowing even in our tough times He is with us and we just need to stay the course.

Excellent post Misty,
It is essential to stay up to date on the most current drivers as they can cause all kinds of issues with monitors. I have an HP Pavilion laptop that I have to update the Intel drivers on constantly as some of the HP’s have been known to have issues with flickering related to the graphics driver, but as stated the first step is to always make sure there is power to the display. As an agent that troubleshoots computer peripherals all the time, it never ceases to amaze me how many people do not check before submitting a ticket or calling in for this issue.
Great job Caleb,
Way to simplify the explanation of the material. They way you explain input output devices makes it easy to understand on various levels. As you stated, having a basic understanding of the peripheral devices does make it easier to see how the whole system communicates. Realizing that information is “put in” into the computer via the keyboard aids in identifying it as an input device.
Good job bringing up network attached storage and cloud storage Misty. I was thinking only of local storage connected to the physical computer in answer to this question, however I think it is important to mention other methods of storage as well. Excellent post.
Troubleshooting issues with displays can be hardware or software related. Hardware related issues can be associated with power, cables and connectivity, the graphics card, or physical defects in the monitor itself. Software related issues can revolve around drivers, and display settings. Blank screens can be related to power, or incompatible or corrupted graphics cards. Just speaking from a logical, common-sense perspective, I think the first thing to ask when troubleshooting a display is to always find out whether or not the display is plugged in and powered on. This is probably the first thing to check for most electronic devices. Other issues you can encounter are burn in, which is a result of leaving an image on the screen for an extended period of time without changing causing the image to be permanently burnt into the display. This can be avoided prior to occurrence by changing your screen saver options in display settings. Another issue commonly seen can be flickering images which occur when images waver or vary in brightness on the screen. This can be a hardware result such as cables not being connected securely. It can also be a software related issue such as the result of an unsupported display resolution, or an incompatible display driver.
