Week 6: File and Folder Management in Windows



Besides the Internet browser, File Explorer (Windows Explorer) is most likely the most used application in Windows. Whether it's to save files, organize, or create a hierarchical folder structure, File Explorer does it all. It is seamless that we take it for granted, but a lot goes into what was implemented in the background. Computer companies use different file and folder systems; today, we will discuss Windows specifically.

To start, Windows uses the New Technology file system (NTFS) to manage its file system. When creating an account in the Windows system, by default, it will create a file system and default folders like Music, Document, and other folders. The entire file system is managed by the NTFS file system. The NFTS file system is quite powerful; it provides features like encryption (for security), compression (to save data effectively), and larger cluster sizes (up to 16TB partition by default). NTFS permission also controls many aspects of files and folders, such as who can access the files/folders or their control over the file and folder system. For example, if I want somebody to read the files but do not have any other control like editing or deleting, NTFS permission enables me to do that. Another thing about NTFS is that it is compatible with MacOS and Linux to a certain degree.

It’s a little trivial thing that we take for granted, but a lot of implementation and processing is happening in the background. In this case, it's with the file system through the NTFS that Windows uses.

Week1: Introduction and Cloud Computing

Image
Hello everyone, my name is Santosh Pradhan, and I am currently pursuing an undergraduate degree in information technology at Bellevue University. Prior to pursuing my degree, I had no prior experience, except for the basic troubleshooting that everyone learns. So far, I have learned a great deal about networking, basic information technology, and some cybersecurity concepts. Although most of the courses have covered virtualization and cloud computing to some extent, none of them have provided full details. I am excited to learn about cloud computing and its governance.  As the semester progresses, I will update the blog on a weekly basis and share my experiences with you.

Week 12: Tools for Monitoring Network and Blog Wrap-up

There are various tools to monitor a network; monitoring a network can help detect issues, be aware of the problems, or make sure the network does not have any anomaly in the network. Here are some of the tools that can help to monitor the network: ·        Packet Sniffers – a software tool that tracks and collects internet packets. The packets that are collected will be stored in a file called a capture file.  Usually, the packet sniffer software also comes with a packet analyzer to analyze the packets that were captured. ·        Protocol Analyzer – this is a program that analyzes the packets that packet sniffers capture. A good program can let the network administrator filter information based on their needs. One of the well-known software is Wireshark. ·         Packet Flow Monitoring – this tool tracks traffic and packet flow between devices. This helps to track the volume and ...

Week 3: Migration to the Cloud

Image
  This week, we learned about the various decision-making processes involved in migrating to the cloud. The book talks about five major phases of the migration process: Assess, Plan, Migrate, Validate, and Manage . While assessing and before initiating the migration process, it is essential to establish a baseline of the network, operating system, and other key performance indicators. It is essential to minimize the impact of downtime and maximize network bandwidth availability during the migration. After the planning process is done, there are various ways to execute it; the common migration processes are P2V, V2V, V2P & P2P. Amazon also provides a migration truck to make the process. The book also discusses deploying the migration and validating it to ensure that it is working through various types of testing, including functional testing, performance testing, load testing, and others.
