Week 4 Summary

Networking is essential for connecting computers and devices to share information. Several key technologies enable smooth communication in a network. One such technology is TCP/IP, which is the standard protocol used for transmitting data over the internet. It's like the ‘language’ that computers use to communicate with each other.

IP Addressing is another crucial concept. Every device in a network needs a unique identifier called an IP address. This allows devices to send and receive data. Sometimes, a network is divided into smaller groups, called subnets, to improve efficiency. Tools like DHCP (Dynamic Host Configuration Protocol) automatically assign IP addresses to devices in a network.

Wi-Fi is a technology that lets devices connect to the internet without wires. It works using wireless signals and is based on rules set by the Wi-Fi Alliance. Wi-Fi is very popular because it allows people to connect easily and move freely without being tied down by cables.

However, not all networks are wireless. Some networks still use physical cables like Ethernet cables. These cables come in different types, which offer different speeds and can cover different distances. In modern networks, fiber optic cables are also used. These cables use light signals to send data at extremely high speeds, making them perfect for fast internet connections.

To keep a network running smoothly, it's important to use the right tools. For example, Windows offers basic tools to help troubleshooting and fix network problems.

In conclusion, networking is a mix of wireless and wired technologies. It also involves using the right tools to ensure fast and efficient communication between devices. Understanding how these technologies work helps us stay connected and enjoy a smooth internet experience.

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...
