A network topology

A network topology refers to the arrangement of devices in a network. Common types include star, bus, ring, mesh, and hybrid. Star topology is popular because it’s easy to set up and reliable. Mesh typologies provide extra backup, making the network more fault tolerant. Each type works better for different situations, depending on factors like size and cost.

Choosing the right cables is essential when building a network. Common cable types include twisted pair cables (like Cat5e and Cat6), coaxial cables, and fiber optics. Twisted pair cables are the most common for local area networks (LANs) due to their affordability, while fiber optics are used for faster speeds over long distances.

The Institute of Electrical and Electronics Engineers (IEEE) creates standards for networking, like IEEE 802.3 for Ethernet and IEEE 802.11 for Wi-Fi. These standards help ensure that devices can communicate smoothly across different networks.

Understanding these topics is essential for passing the CompTIA Network+ exam and building a strong foundation in networking.

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...
