Excellent explanation on both sides of the differences between ROM and RAM. Your points are all helpful for me to understand better. ROM is smaller in size and storage capacity than RAM. Due to their static nature, they do not need to be updated. This is remarkably interesting to learn more about computer stuff and gain more knowledge.
Both RAM and ROM are present on our computer. RAM is volatile memory that temporarily stores files you are working on. ROM is non-volatile memory that permanently stores computer instructions. ROM is cheaper than RAM. Data stored in RAM can be modified, deleted, retrieved, modified, and read. Data stored in ROM can only be read and cannot be changed or deleted. Data stored in RAM is used by the central processing unit (CPU) to prepare the current instructions. For example, Rom chips are used to store BIOS programs on motherboards. RAM chips temporarily store files used by the computer. For example, the document you are working on, the image you are editing, or else the game you are playing. RAM is a piece of computing device hardware that stores the operating system, application programs, and data currently in use for quick access by the device’s processor. RAM is the computer’s main memory. Real life examples of RAM are foind in desktop computers, laptops, or mobile phones. Desktop or laptop RAM today varies from 4 GB to 64GB.
The devil does not want us to know the truth about him. Stan can never pursuit my soul because Jesus is protecting me. In Psalm 31:4 “Get me out of this net that has been set for me because you are my protective fortress.” The good news is Jesus will never forsake you, no matter what your enemy may threaten. Satan demonically clever in the way he attacks us, but the Holy Spirit is supernaturally powerful than Satan. The prayer of spiritual protection is “in the name of Jesus, I submit all of me to you. Here I am. I resist the enemy by calling on your name, Jesus, to save and help me. Draw me close to your heart, where I am safe and secure in your protection.” I never felt helpless under Satan’s spell because I pray, read bible, and frequently go to church God keeps me safe and secure with His arms.
As in the IT field we should know troubleshooting techniques behind the computer’s power supply instantly. If you suspect that your power supply is dying, replace it. A common clue which indicates a failing power supply is high-pitched whining. About any intermittent problem can be caused by a faulty power supply.
Make sure the power strip or surge protector is plugged in and powered on. Check the back of the computer for loose cables, especially the main power cable. Check the outlet for power problems or try plugging the power cord into a different outlet. Try another power cord. The essence of power supply troubleshooting is to identify the power supply causing the problem in your system and replace it if necessary. If you are experiencing any of the following symptoms, your computer may be running low on power and should be tested. No power when the power button is pressed, intermittent power, noise from fans or capacitors, burning smell, or damaged components from voltage spikes. You can see the power supply of your PC by removing the side panel of the case. If you bought an off-the-shelf PC, you could also check the power supply in your computer’s manual or contact the manufacturer. If you know your PC’s power supply, you can upgrade other parts of your computer, such as your graphics card.
Great essay about motherboard and CPU which is helpful for me to understand better. They are responsible for processing and executing instructions and act as the brains of your devices. The CPU is seen as the main and most crucial integrated circuitry (IC) chip in a computer, as it is responsible for interpreting most of the computer’s commands.
A computer motherboard is usually the largest printed circuit board in the machine’s chassis. It distributes power and facilities communication between the central processing unit (CPU), random access memory (RAM), and all other computer hardware components. A motherboard acts as a single platform that connects all parts of a computer. Connect CPU, memory, hard drives, optical drives, graphics cards, sound cards, and other ports to expansion cards directly or via cables. You can think of it as the backbone of your computer. A motherboard is the backbone that holds your computer’s components together in one place and allows them to communicate with each other. Without these, computer parts such as CPU, GPU and hard disk cannot interact. The CPU is the brain of the computer, containing all the circuitry necessary to process input, store data, and return results. The CPU follows instructions from a computer program that tells it what data to do and how to process it. Without a CPU follows instructions from a computer program that tells it what data to do and how to process it.
Excellent explanation on how troubleshooting works and the importance. People should learn how to troubleshoot in their laptops or computers because it is easy for them to find the issues with the computers and will be solve easily. You wrote it well, and all your points are valid and important.
Troubleshooting is a systematic way to solve problems. The purpose of troubleshooting is to determine why something is not working as expected and explain how to fix the problem. Troubleshooting helps identify symptoms, eliminate probable causes of the problem, and seek confirmation whether a solution returns the product or process to operational status. Formally, you can think of the troubleshooting process as an application of hypothetical deductive techniques. Iteratively hypothesize about potential sources of error to obtain a series of observations about the system and a theoretical basis for understanding its behavior and test these hypotheses. The purpose of troubleshooting is to receive operational problems quickly and efficiently. This reduces business downtime and prevents major losses. Troubleshooting also identifies areas that are costly to your business. Troubleshooting is the ability of individuals to adopt a systematic approach towards identifying and then solving the issue. In simple words, troubleshooting is the problem-solving abilities of a person.
Yes, the lord is my shepherd, shall not want; he makes me lie down in green pastures. He leads me beside still waters; he restores my soul. There will be swarms of living things wherever the water of this river flows. Fish will abound in the Dead Sea, for its waters will become fresh. God has a constantly flowing river whose sparkling streams bring joy and delight to his people. We can experience true rest when we spend time in God’s presence, praying or reflecting on His Word. As we take time from our busy schedule, we can still be still, silent, present, and allow Him to work in us. Rest is found in Jesus. The joy and peace I need starts by running to Him, abiding in Him, trusting in Him, and staying close to Him. I find God’s presence by taking the time to pray and slow my pace, sometimes my routines and habits can overwhelm or distract me, and I will remove distractions, and practice thankfulness.
You have written it well about SOHO network. The SOHO network will go rising. Not just because of the technological developments like IoT and data storage but more importantly the security reasons. Technological developments make people more vulnerable to cyber-attacks. Resilient of small businesses for these security reasons which usually they could barely stand for themselves.
I agree with you that SOHO routers improve signal, audio, and video quality such as web conferencing with poor signal quality or jitter hinders interaction with colleagues and clients. If you have a business in need of more technology, software, like entrepreneurs or architects, you will need more advanced networks like the ones in big offices. Soho network will cover your needs without spending a fortune. Many devices could connect to the network.
SOHO routers are broadband routers designed and marketed for small offices and home offices. Most of these companies’ workloads are on the Internet, so they need a local area network (LAN). This means the company’s network hardware is built for this purpose. A SOHO network may be a mixed network of wired and wireless computers. Because these networks are enterprise oriented, they might also include printers and Voice over IP (VoIP) and fax over IP technology. Small office or home office (SOHO) routers are essential network devices for millions of consumers. They are often the only entry and exit points for SOHO networks, managing domain name resolution, security system protection, dynamic addressing, wireless connectivity, and of course routing. Routers send and receive data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, a router can combine the function of these components and connect these devices to improve Internet access or help build corporate networks.
You have given some splendid examples of mobile and physical devices which are great. As you mentioned about 2FA is essential to web security because it immediately neutralizes the risks associated with compromised passwords. If a password is hacked, guessed, or even phished, that is no longer enough to give an intruder access without approval at the second factor, a password alone is useless.
That is a great explanation about three different vulnerabilities on mobile and physical devices. You have written it well and your points are valid. Also, using additional security such as fingerprints scanner and swipe cards at vulnerable positions on the network such as server rooms. Restrict parts of the computers which may be easy to attack such as USB ports and floppy disk drivers. Install surveillance cameras at key points. Physical security protects cybersecurity by limiting access to spaces where data is stored, and the reverse is also true. This information you wrote is extremely helpful for IT students and will help them gain more knowledge about essential information as you mention.
