Traveling through Networks using Pings and Traceroutes



A ping is a tool used to test the connectivity between two nodes or devices. A traceroute is a tool that is used to show how data on the internet travels from its source to its destination. The way that pings work is that the ICMP sends an echo request packet to the destination, and if the connection is good the destination responds with an echo. The way that a traceroute works is by sending the ICMP packets, and the routers along the path get these packets. The routers use the packets to decide if they can effectively transfer the data.  These work by typing out the command and either the domain name or the IP address. The domains consist of .com, .org, .edu, and .gov. Some countries get their own as well like the site I used from Australia ends in au and the site that I used from Canada that ends in ca.  

I pinged google.com, cbc.ca, and nsw.gov.au. I noticed that the pings between google.com and cbc.ca pinged back in a similar amount of time except for two from google.com that took a longer time to ping back.  I also noticed that the Australian sites pings were closer to the Canadian site except for the first and second pings. The first ping for the Australian website took the longest out of all the sites and the second ping took the shortest amount of time out of each website.  When using the traceroute command I noticed that the responses for google.com and the Australian site were the quickest to respond. The Canadian site was the slowest to respond. I noticed that all of them popped up with no reply after the first five and ended with too many hops. This could have happened because my connection was not good, or I missed adding something to the command. I am not that experienced with using this on the Chromebook. Two reasons that a ping request or a traceroute command might time out is if there are firewall problems or there is network congestion.

Importance of Network Security

  Information and system security is a top priority for many individuals and organizaitions. They need to be able to keep a connection to the internet and keep their files safe in order to run their business. One thing that can interrupt this is attacks through ping commands. Two common ping command attacks are ICMP flood and ping of death attacks. The ICMP flood is a DDoS attack where the attacker overwhelms the targeted network with continuous pings. This can cause congestion in the network and prevent people from accessing it. The ping of death attack is a variation of the ICMP flood. This is also a DDoS attack, but this time the attacker sends oversized ICMP packets that exceed the packet size. This causes the targeted system to crash or freeze. Other attacks that can happen to individuals and organizations systems or networks are computer viruses and phishing attacks.  Computer viruses are programs that are spread throughout the computer, starting in the files or system...

Documenting a day with Microsoft Office 365

  Microsoft Word, Excel, and PowerPoint can all be used for specific things such as projects, keeping track of inventory, or data and essays. They are great for not only school projects but can be used by many different businesses as well. While using all three while documenting a day of my life it was clear that they all had their own advantages and disadvantages. Reflection is a great way to provide your experience with the application and will help to find out when each should be used.  Word works best when completing an essay due to its many different tools. Word allows the user to change the font, the font size, the alignment of the text, the format of the text, and it will enable the user to bold or italicize the text. All of these are beneficial when it comes to creating an essay. Excel works best when you need to keep track of data or inventory. It allows the user to create formulas to calculate data, charts that can keep track of a business's budget or how much a spec...

Programming with Scratch

Image
  Scratch is a great website to use if you are just starting out with coding. It is very straightforward and easy to use. There are other coding languages, such as Machine language, Assembly language, and High-level language. All of these programs can be best used in their own ways. The differences between the coding languages can be what makes you decide which one to use.  I had a good time creating a program on scratch, and the experience was very rewarding since I have little experience with coding. One difficulty that I encountered on scratch was when I tried to get the one sprite to ask the other what its name was and have the other one answer using the sensing option. I overcame this by using the looks option so I could get them to say, “What is your name?” and then I used the wait command before responding so that it would look like a real conversation. It was nice to see how each part of the code worked by testing it after connecting it together. This allowed me to see...
