       Ping commands are useful when it comes to troubleshooting and checking to see if a website is available and how fast you would be able to access it. However, ping can also be used for malicious intent. Today I will discuss an attack possible by means of ping commands. I will also get into computer security incidents like computer viruses and phishing and discuss what makes computers vulnerable to them, the damage they can inflict and protection methods for each. Ping Commands for Malicious Intent One major attack that can be accomplished by using ping commands is a denial of service attack. A denial of service attack is when a target website is basically overloaded to the point that it is rendered useless. By using the ping command, an attacker will send oversized data packets to a target website that will be too much for it to handle and causing the site to crash, not allowing legit users to use that site for a certain amount of time. An example of this ...

    Computers in The Workplace Today, I will explore the significant impact computers have on the healthcare industry. While my perspective comes from personal experiences as a visitor and patient rather than a professional standpoint, it's evident that computers play a crucial role in modern healthcare. Changing Healthcare Through Technology           One of the most noticeable impacts of computers is the transition from paper based records to digital medical records. This change has made it easier for patients to access their own records, schedule appointments through computer application systems, and even how they check in for appointments using digital devices. Many healthcare facilities have replaced the traditional paper and clipboard method with iPads to collect patient information. Computers also allow the ability for telemedicine, enabling patients to consult with healthcare professionals from home. These are just a f...

  PING Ping is used to check if a website is reachable. When pinging a website, packets are sent through the network via routers to a destination server and if it goes through without interruption, that destination sends back an acknowledgment response. That response will include data about the ping, such as the number of packets sent and the time in milliseconds that it took to send and receive back that acknowledgment response for each packet. It will also show if any of the packets sent did not make it to its destination. I pinged two different websites, one being News.com.au out in Australia and Rakuten.co.jp in Japan. Both pings sent 4 packets and none were lost as shown below.   However, I did notice that one of the packets from the Australian site took significantly longer than the other 3. The same thing happened to the website out of Japan, but the time difference wasn’t as significant. As far as the two, the Australian site took an average of 82ms and the Japanes...

    All throughout the information technology world you will at some point have to utilize applications such as Microsoft Word, Excel and PowerPoint. These are some of the most common and basic applications that are out there today. Today I will be discussing the advantages and disadvantages of each, and how they compare to one another. Microsoft Word Advantages: Versatility in Writing: Word is perfect for all writing purposes, whether you're drafting a book, essay, poetry, contract or work memorandum. Formatting: It offers a lot of formatting tools, including various font styles, sizes, alignments, customizable margins, and borders for a more appealing document. User Friendly: This application is really easy for the user to utilize, navigate and learn quickly. Disadvantages: Limited Data Formatting: Word excels in writing and formatting that text, however, it lacks the data formatting capabilities found in other applic...

  Today I will be evaluating the Great Wolf Lodge mobile app. My family and I enjoy taking trips to the Great Wolf Lodge and try to go a couple of times each summer. Let me take you through my experience with this user friendly app that makes planning and enjoying our trips even easier. Usability and Navigation I find that the useability of this app is user friendly and very easy to navigate all the different icons and options. There is a lot of different items you can click on and view but it’s not overwhelming in my opinion and broken down into different parts such as viewing the different attractions and shops, or the events that are taking place that day just to name a few. So, you can really pick and choose what it is you want to view or do and go from there. Functionality The functionality is awesome with the app. You can do pretty much anything you want in the app as far as a trip to a water park goes. There really is no need to even call the lodge directly, I haven’t encoun...

  Having very little IT experience, this project is my first steps towards a better background in that department. It is exciting and makes me nervous at the same time as I have never used nor even read about programming languages before. This was the same for the program Scratch, but the outcome was positive and gave me a better understanding of what program coding consists of. The following is the link to my Scratch program :  https://scratch.mit.edu/projects/1116622511 This was quite interesting, having never used the program Scratch, I found myself struggling a bit at first trying to figure out how all the different codes would affect the outcome. Once I had a decent grasp of that, I knew what I wanted to do but getting the figures to do it how I wanted was the challenge. The biggest challenge was getting the timing right for everything. I overcame this by simple trial and error. I would set a time for something, run the program and see if it needed to be slowed or sped up...
