Understanding TCP/IP Applications and Network Naming

The internet works because of a system called TCP/IP. It stands for Transmission Control Protocol and Internet Protocol. These are rules that help computers talk to each other. TCP helps send data correctly. It breaks big data into small packets and makes sure they arrive in the right order. IP gives each computer an address, like a home address, so data knows where to go. Many apps use TCP/IP. For example, web browsers use HTTP, email uses SMTP, and file sharing uses FTP. These apps help us browse websites, send emails, and download files.

Network naming is also important. Instead of typing a long IP address (like 192.168.1.1), we use names like google.com. This is easier to remember. The system that changes names to IP addresses is called DNS, which means Domain Name System. When you type a web address, DNS finds the correct IP address. Then, your computer connects to the website.

So, TCP/IP and DNS work together. TCP/IP moves the data, and DNS makes sure it goes to the right place. Without them, the internet would not work.

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...
