Comuter Viruses and Wrap Up Blog

 From 1971 to 1980, the first computer viruses like Creeper and Elk Cloner appeared, and the term computer virus was coined in 1983. Early viruses were simple and caused little harm. Antivirus development began in 1987 with signature-based detection, but advanced methods like heuristics and sandboxing emerged later. A firewall protects systems by blocking harmful traffic, and cryptography secures data by encoding it into unreadable formats. Computer viruses harm systems by replicating, while antivirus software uses methods like signature detection, sandboxing, and data mining. Despite these efforts, new malware like ransomware remains a challenge for detection.

This blogging assignment was new to me in this course. From the beginning of the course, I searched for a few samples for what blog is and how to write in YouTube and google and found there is a way to express. So, eventually, I liked the format and concept of this course. This blogging assignment has been a valuable experience for me. Although I encountered lots of new information to study, I genuinely enjoyed learning and sharing it in a way that makes it easier to understand for others. Writing blogs allowed me to dive deeper into various topics and discover things I hadn’t thought about before, which kept the process exciting.

From a professional perspective, the assignment proved to be extremely helpful in my current job, particularly when it comes to fixing computers. The knowledge I gained through research and writing helped me develop problem-solving strategies and stay updated on new methods and tools, making me more efficient at troubleshooting and repairs.

Looking ahead, I can definitely see myself blogging in the future, even when it's not an assignment. It’s an effective way to share knowledge, connect with others, and build a platform to demonstrate my expertise.

Week 4 - Hardware Repair

 When performing computer hardware repair, it's important to pay attention to several key points to ensure successful and safe repair. Safety precautions, Diagnosing the problem, component capability, using proper tools, component replacement, handle software issues separately, reassemble carefully are the major things that I have learned from the video and my own research.  1.  Safety Precautions: v   Power Off & Unplug: Always make sure the computer is turned off and unplugged from the power source before starting any repairs. v   Ground Yourself: Use an anti-static wrist strap to avoid damaging sensitive components with static electricity. Alternatively, ground yourself by touching a metal object. v   Handling Components Carefully: Avoid touching the pins or contacts on components (like RAM, CPU, or motherboard) to prevent damage. v   Heat: Some parts, like CPUs and power supplies, can get hot. Be cautious to avoid burns. 2. Diagnosing...

OS and configuring email on Mobile Devices

  OS and configuring email on Mobile Devices This week, I got the opportunity to overview both operating systems iOS & Android that are used on mobile devices, enroll devices for on-premises MDM in Configuration Manager system, and analysis of configuring Email on Mobile Devices. iOS is the operating system made by Apple for iPhones and iPads. It was first released in 2007 and has been updated many times since. Each new version brings improvements like better speed, more features, and security updates. iOS has made Apple devices very popular because it is easy to use and works well with other Apple products. It also has a big app store where users can download many different apps. iOS helps Apple stay competitive in the smartphone market by offering a smooth, secure, and reliable experience. Android OS, developed by Google in 2005. It is an open-source operating system primarily used in smartphones and tablets. It has grown to dominate the global smartphone market, with o...

Week 3- Selection of CPU, RAM and Processor

  Choosing the right CPU is the biggest challenge for non-tech people in this century. When choosing a CPU, we can consider such as number of cycles a CPU can perform per second called (GHz), number of cores and its purpose, compatibility of processor with the CPU and the budget. After I completed chapters 3 and 4 in a book, and other materials that have various information about processors, RAM (DRAM) manufacturers, SSD, coolers, and overall CPU selections, I would like to summarize some of the points in this post. Modern CPU's can process multiple commands in parts of commands in parallel. Intel and AMD have built in support for running more than one operating system at a time a process. (is called visualization) The CPU is composed of multiple chunks of circuitry to handle the many types of calculation our PC needs to do. When selecting a CPU you need to make certain the motherboard can accommodate or if you are buying a motherboard along with the CPU then get the right CPU fo...
