NETWORK SECURITY

  Ping Commands' primary use is to test various points in network connectivity. Unfortunately, the ping command can be used to attack a network or website. These attacks are often called Denial of Service (DoS), which overloads a web server by sending too many ping requests. DoS attacks can slow down the web server, even causing it to crash (Guru99.com, 2020). These attacks work because the ping command requires sending small packets of information out to an IP address, which sends a response back. When thousands of ping commands are sent to one IP address or a web server, it causes it to slow down or crash due to the vast amount of bandwidth needed to process the packets being sent. A computer virus is a malicious software that infects the computer to spread to other networks and computers. Symptoms of a computer virus may vary based on the type of virus. However, common symptoms are unusually slow performance, frequent crashes, unknown programs, and mass emails being sent from

COMPUTERS IN THE WORKPLACE

 The industry I have chosen to discuss is the military industry. Computers play an essential role in the military. We live in a digital age, and the military adopts certain technologies that can help in any way possible. First, the military is no exception to the world's current state, where people must communicate while respecting social distancing. We currently use Microsoft Teams to conduct our mandatory meetings. Many are teleworking and use multiple apps to stay on top of their tasks. Secondly, the military has been moving towards the unmanned type of warfare vehicles. For example, we have unmanned drones that fly using computers to keep military members away from danger. Some of these drones are even controlled by Xbox controllers (Wired, 2008). The military will continue to adapt technology to prevents loss of life. It is essential to be computer literate because as technology advances, so does the military's technology. It may take some time to incorporate brand new tec

TRAVELING THROUGH A NETWORK

  This was my first experience using a command prompt to ping an traceroute and IP address. I learned a lot and found it interesting to track a packet as it travels through the internet. Even more interesting, the ping and Tracert command have various options to change how the command is ran. The packet travels through the network by a series of hops until it arrives at its destination. Each 'hop' represents a host that the packet travels through before the destination host. I ran a Ping command to three different websites. I was surprised to find out that the website located on Japan servers resulted in the fast round trip time at an average of 9ms. The Google website, as well as the Australian website, took 55ms and 69ms, respectively. No website resulted in any packet loss.  While trying to find websites to ping, I noticed that government websites resulted in 100 percent packet loss. I thought something was wrong at first until I choose a different website. I believe this ma

DOCUMENTING A DAY

  In this week’s assignment, I was instructed to uses three different software applications to document my day in my life. The three software programs were Microsoft Word, Excel, and PowerPoint. All three applications serve a different purpose, which is apparent after this week’s assignment. Word is an excellent application for writing out the text. Excel is great for inputting data and charts into a spreadsheet. PowerPoint is used to create a presentation a slide at a time, and it has a wide range of tools to help you do so. I believe it is essential to understand which application to choose to complete your task effectively.                     The advantages of Word are that it is practically universal and can be used to transcribe text quickly. It is an easy way to save text for later, and your document can provide easy travel via email or the cloud service. Excel is a great application that gives the user the ability to analyze large amounts of data. The ability to format cells

REDDIT MOBILE APP: A BRIEF REVIEW

       Reddit is a social media platform where people can discuss and view topics that are of their interest. Reddit is accessed through a web browser or mobile app. I have used the mobile app for over eight years and love it. The concept differs from the traditional social media giants (Facebook, Instagram, and Twitter) in that the users don’t post selfies or personal information (typically). The app allows users to post images, videos, or ask a question. Users post whatever they want in specific categories called subreddits. The app also uses an up-vote/down-vote system where the most popular posts will populate the home page and generate the most discussions. Reddit has a home page that contains the most popular post for any given category. The users can tailor their viewing experience by following subreddits that are of interest to them. The heart of the app is in the comment section, where users can discuss with one another. The comment section follows the same up-vote/down-vote p

PROGRAMMING IN SCRATCH

My experience building in the Scratch program was difficult at first. I had to watch multiple tutorials to understand basic operations. My goal was to try to utilize different code lines to learn as much as possible while creating a unique program. I had trouble with figuring out what function performed what operation. Specifically, I had difficulty with incorporating sound. I tried timing it right with my characters' dialogue, but the sound did not start when I  wanted it to begin. Eventually, I figured it out by using the wait function. I learned quickly what everything did after playing around with the different functions. I feel with more time and exploring the various functions; I could have made a better product. There is still a lot for me to learn in Scratch. I enjoyed learning about the different types of coding languages within the course text. Python seems to be the easiest for me to understand, and Machine Learning was the hardest to grasp. However, Machine Language w
