Traveling Through a Network

My experience with using the ping and traceroute commands was interesting. I have learned more with this hands on experience than any other lesson that I have earned while being in TEC 101. If I remember correctly, I am fairly familiar on how packets travel through the network. Packets travel through the seven layer model known as Open System Interconnect (OSI). This system identifies where the packets need to go throughout the network with a series of hops. The main difference that I saw upon my completion of this assignment was the speed traveled. The average time differed with each country I am assuming. The average speed for the us link to google was fast in comparison to the link that I had selected for japan. The ping and traceroute commands can be used to troubleshoot internet connection problems. The ping uses a simple command to help determine what the reachability of a device on a network is. On the other hand, traceroute is used to traced that route that the packet was sent through as it travels to its destination. Referring back to Open Systems Interconnect (OSI), the transportation layer is when the packets begin their transition to the correct destination, while the network layer works a little differently. The network layer is the third layer for the bottom of the OSI model. This layer accomplishes the routing of data for the source to the destined host.

One thing that can cause the traceroute to fail is that the router might have rejected it. One thing that can cause the Ping to fail is that it did not receive a response back within the time period that was allotted. Lastly, latency is a huge thing when it comes to devices. Every device has been designed to respond after it is given a proper command. Latency affects the overall relationship between the roundtrip time and geographical location. Nevertheless I had a wonderful time completing this discussion, unfortunately my computer isn’t allowing me to post the discussions normally either so I have to attach a link.

The Ping command can be used to trouble shoot internet connection because it performs a basic test to see if the remote host is available. This is beneficial because it shows whether or not a host is even alive to connect to. On the other hand, traceroute tests the complete route network packets take from one host to another. This is beneficial because it identifies network slow downs and congestions that may occur. The only way these two commands would time out is because there is no where to connect to or the router denies or reject the traceroute packets.  Therefor it is clear that both Ping and Traceroute are quick and easy to use to determine if specified servers are reachable.

Tech Topic Connections

The tech topic that I have selected is “How Computers Operate”. Over the course of time I took a course online that introduced me to the process of how the network operates. A computer is a collection of hardware and software components that help the user complete many different tasks.  The network works through the operation of the Open Systems Interconnect (OSI) Model.  This is a Seven layered model that operates the network which is installed on the computer. Overall “How Computers Operate” connects to the fundamentals of information technology covered in this course. Information Technology is the use of computers and just all around knowing how they function. Technology is advancing everyday and it's just going to continue to advance. It is important to be able to maintain and troubleshoot computers and their networks, systems and databases. On the other hand, Computer Science is more about the arctic of things. It refers to designing and building computers and computer pr...

Network Security

Computer systems are vulnerable to each kind of threat due to software and hardware designed flaws. The lack in these areas expose the computers to all sorts of threats. Technology advancement  is continuous due to the world's dependability on technology. There are a lot more vulnerabilities stored in computers such as having weak passwords, and failing to update firewalls to protect the device. All in all, software is coded by humans and no one writes software completely free of errors that create openings for potential attackers.  In regards to symptoms and damage a breach inflicts after infiltrating a system, it is important to note the many different types. In cybersecurity, there are complex and information breaches. Missing records, peculiar network travel and file changes are telltale signs of a data point breach. This type of breach can have a direct harm on the business’ reputation, privacy and product, as well as the consumer’s security. Nevertheless, after compromis...
