So input output, or I/O devices are the peripherals or hardware components that you attach to your computer which allow interaction between users and computers. Input devices allow users to send data to the computer. Output devices allow data to be exported or retrieved from the computer. Some common input devices are the keyboard, mouse, trackball, microphone, scanner, or joystick. Some common output devices are the monitor, printer, speakers, headphones. In addition to input and output devices, there are some that can function as dual input/output devices such as touchscreen monitors which can be touched to input data while simultaneously displaying the results as output on the screen. CD/DVD drives input the data to be read or executed, while outputting the data to the monitor or sound to speakers externally. USB drives can also perform along this same capacity.
Physical computer storage refers to disk drives, RAID storage, optical drives, flash drives, memory cards or SD cards, as well as magnetic tape drives. Disk drives are usually magnetic hard disk drives, or solid-state drives. Magnetic hard disk drives contain plates/platters made of aluminum or glass that can be magnetized & demagnetized to store binary data in the form of zeros and ones. Solid state drives are non-volatile flash memory chips which store the same information. While both HDDs and SSDs can be housed internally and plugged into the motherboard, they can also be connected externally by a USB cable. You can acquire these drives in a 3.5” size, generally for desktops or 2.5” size, generally for laptops. Additionally solid-state drives are typically created for various expansion slots such as PCIe, NVMe and M.2. SSDs offered in these formats are usually much smaller than their 2.5” encasings but may come in these sizes for standard accommodations.
This devotional reminds me of Mark 4:16 & 17. Jesus was explaining the parable of the sower to the disciples and believers because it was given to them to know the mysteries of the kingdom. Their walking away is indicative of the seed that was on stony ground. When they heard the word they were exited and received it with gladness, but as soon as the first sign of opposition for the word’s sake came, they were offended & there was no root in them. I like to say there was no stick-to-it-iveness.
In Matt. 16:4 Jesus said a evil & adulterous generation seek for a sign (James, 2019). By using the word adulterous here He is saying they were unfaithful in their worship and allegiance to God. Furthermore the only sign He said He was going to give was that of Jonah. Jonah was symbolic of the Lord Jesus Christ in the Old Testament in that he died in the belly of the whale for three days and was resurrected to preach repentance to the people of Nineveh. Thomas was a disciple of Jesus Christ & he didn’t believe Jesus resurrection until he saw the nail scars in His hands. Jesus told him he believed because he saw. We today are blessed because we believe in the resurrection of Jesus Christ without having even seen Him.
This devotional reminds me to keep my faith in Jesus Christ in spite of what my natural eyes might see & continue to walk by faith and not our natural sight. It also reminds me that the Christian walk will not always be easy. Sometimes we will face persecution, many times, by the ones we love most and are the closest to us. The power of God to do the miraculous is just as strong today as it ever was & we should not lower our standards because of what people around us say, rather hold the word of God in such high esteem that we arise to the standard it calls for and continue to believe. Mark 16:17 tells us the signs that follow those that truly believe.

Good post Carlos,
Just to expound on expansion slots a bit more, I think the reason many companies & organizations use Dell is due to their customizability (if that’s a word). While I definitely have my preferences when it comes to manufacturers, you cannot find many models with the number of replaceable components & expansion capabilities that Dell provides. Many manufacturers hardwire most their components to keep you buying new laptops every few years, while i feel like Dell does a good job at trying to keep things interchangeable as possible. This has been my experience but I am curious if anyone else has an opinion on this?
Excellent post Isabelle,
You did a great job at explaining the key difference between RAM & ROM with simplicity. With loss of power to volatile memory, the memory is wiped & no information is stored.
Great Job Caleb,
You were detailed and poignant with your description. I always like to check the power supply from a different outlet as well to make sure it isn’t an issue with fluctuation in power from the outlet itself.
Expansion options are slots on the motherboard that allow physical hardware components to be added which expand the devices or peripherals on the computer. These options include but are not limited to;
USB or universal serial bus
Firewire
Thunderbolt
SATA port (Serial AT attachment)
HDMI
Registered Jack or RJ
VGA, DVI, Display Port Video
Analog and Digital Audio
Sound cards
RAID controller
Network cards
Wi-Fi Adapters
One of the main benefits of expansion is the ability to customize and upgrade your computers’ functionality and performance. Most motherboards have manufacturer specifications that tell you how much you can increase the RAM or hard drive storage capacity as well as CPU. If you are running out of storage space, you can upgrade your HDD or SDD to expand your storage capacity. This can be done through the RAID controller or the use of an additional SATA port leaving the original HDD in place. If you want to upgrade the RAM to max capacity, it may have come with 8 gigabytes of memory but can be upgradable to 64 GB or more. The motherboard usually has somewhere between 2 to 4 expansion slots for memory and takes specific RAM modules. If you are upgrading to 32GB, you may have to purchase two 16GB modules or four 8GB modules. It all depends on the manufacturer.Read only memory is what it says, it is a type of non-volatile memory on the motherboard of the computer that can only be read, as what is stored on the ROM is already written from the manufacturer. It houses essential instructions and data even when the PC is off and cannot be overwritten.
RAM, or random-access memory on the other hand is your temporary storage memory which is used by the operating system and various applications so information can be processed via the CPU. It can be written to and overwritten as this memory is not permanently fixed to the motherboard, and unlike ROM, RAM modules are interchangeable and upgradable on the motherboard. There are various RAM modules such as SIMM, DIMM, SODIMM, RIMM, and NIC.
ROM is non-volatile meaning the data is not affected by the removal of power. Although it is slower, it is permanent, providing long-term memory storage even without power. RAM is volatile memory; it is quick and fast but is also temporary and does not retain data storage once powered off.
Some of the different issues you will see when a PSU fails are the PC does not turn on, HDD & fan do not spin, blue screen errors, overheating & random freezing, hanging or shutdowns. When troubleshooting a power supply, I would start by checking basic connections. Make sure the power supply switch is on, confirm that all cables are securely connected to both the power supply and the wall outlet. Then I would test the PSU form a different outlet to rule out the outlet as the problem. You could also grab your multimeter & test for 120V from the power outlet. If the computer still does not turn on, you can perform the paper clip test on pins 15 & 16 in the ATX connector while in the PC and see if the fan spins. If not, remove the PSU from the PC, keeping the paper clips in and then test individual pins for 3.3V, 5V, or 12V.
The other way you can test it is to buy a Power Supply tester from Micro Center and plug the appropriate 24 pin and 4 pin connectors in to, then plug it up to an outlet & turn it on. It will display the voltage coming of each pin. Either the light will be red for bad pins, or it will not light up at all, then you will know if the PSU is defective.
In this passage the Pharisees are trying to find fault in Jesus and his disciples for picking corn to eat on the Sabbath. As we all know according to law no work is to be done on the Sabbath. Jesus was trying to show them that He is Lord or Master of the Sabbath, meaning He had dominion and authority over the Sabbath. He was trying to show them the needs of people outweigh the observance of the law. Which is why He quoted Hos.6:6, where God said, “I desired mercy, and not sacrifice; and the knowledge of God more than burnt offerings” (James, 2019). Jesus told the Pharisees in this passage He would have mercy rather than sacrifice to further emphasize His passion for the needs of humanity.
This passage shows that God is concerned about our needs. John 10:10 tells us Christ came that we might have life abundantly and Hebrews 4:15 tells us Jesus, our high priest is not a high priest that cannot be touched with the feeling of our infirmities. Finally, 1 Peter 5:7 tells us to cast our cares on Him for He cares for us. I thank God He cared enough about me not only to send His son to save me, but that any need we have today I can take to my Daddy “Abba” and He will make room for me, time for me, and provision for me.References

The analogy of the motherboard as the backbone of the computer is great. It is great that manufacturers create motherboards with expansion in mind knowing that technology is every evolving. Lower level boards may have processors hard wired on the motherboard, but most boards will have chipsets that allow for possible upgrade with quicker processors and memory slots that are expandable from 8GB to 32, 64GB or greater. Also it’s worth mentioning many manufacturers today produce multi layered circuit boards. Those components that are bound together by design on motherboards would otherwise be multiple breadboards with a mass of wires running from component to component. They are very essential indeed.
Amazing analogy Carlos,
I couldn’t have said it better myself. The CPU being the brain and the motherboard being the nervous system. The highway is a great analogy as well since the motherboard interconnects each component so the CPU can transport information across the information super highway.
Excellent post Isabella,
I think documenting the problem & solution are both very valuable parts of troubleshooting. As you stated many issues that arise when troubleshooting and fixing an issue. But proper documentations of the issue makes it so if the issue arises again there is recorded procedure on how to resolve that issue whether you see it or another colleague a thousand miles away, and we all know that most devices like cars have specific manufacturing defects that are common to the make or model.
The motherboard also referred to as the main board, system board, or controller is the physical board that houses every component required to make your computer function. Whether it is an actual HP, Dell, or Apple desktop or laptop or not, any programmable device that can compute mathematical and logical functions is considered a computer. Down to a simple calculator or electronic watch. The components on a PC motherboard usually consist of the CPU, memory, and various connectors for graphics interface, HDD, SDD, and other I/O devices
The CPU, which I refer to as the processor, is the Central Processing Unit. The processor does just that, it processes and executes the calculations and instructions of whatever it is programmed to do. In a calculator the processor is programmed to execute or output the results of mathematical functions. In a watch the processor is programmed to output the time of day in military or 12-hour time sometimes in addition to the day of the week, temperature, etc. Both are necessary in order for the computer to operate.Troubleshooting is significant in most any aspect of life. My background is in electronics engineering technology, so I have been repairing hardware for about 20 years and as with any problem you face in life you have to get to the root of the problem in order to determine how to fix it. Deciphering or interpreting the information that the end user or customer gives you is just as vital as finding the problem itself. If the end user tells you it doesn’t work, that can be a million things. The first step with hardware is identifying the issue, finding out if it’s plugged in, if it powered on, do you see any lights, etc.
My current role is as a technical support specialist for printers, so I am no longer physically repairing the hardware, but troubleshooting issues remotely to determine whether it is a network issue, software issue, driver, or something physical that requires a hardware ticket in order to be repaired. No matter the aspect of troubleshooting, it is vitally necessary as a way to quickly identify problems and resolve them.
