 Google Ping and Trace Route Results: Fastest


Ping Results:  Packets: Sent 4, Received 4, Lost 0 / Round Trip Times: Min 16ms, Max18ms, Avg 17ms

Trace Route Results: Number of Routers Passed: 23 / Speed: Fastest, everything below 40 MS which I take as low latency, but I didn't receive a response from 8 of the 23 Hops.

Ping Results: Packets: Sent 4, Received 4, Lost 0 / Round Trip Times: Min 18ms, Max 21ms, Avg 20ms

Trace Route Results: Number of Routers Passed: 10/ Speed: again, everything below 40 MS, and I didn't receive a response from 1 of the 10 hops.

When data is sent over a network, it's broken down into small chunks known as packets. These packets contain not only the data being sent but also metadata about the data, such as the source and destination IP addresses. Routers across the network then read this metadata and decide on the best path for the packet to take to reach its destination. Once the packet reaches its destination, the receiving device confirms receipt back to the sender. 

When you compare the ping and traceroute results from different websites, you can see how the paths to the different destinations differ. The path taken by packets can vary widely based on the geographical location of the destination, the architecture of the network, and the current network conditions. The roundtrip time in a ping or traceroute generally increases with the geographical distance to the server, due to the physical limitations of transmitting data. However, this isn't a strict rule, as network conditions and the number of hops can also significantly affect roundtrip time.

Timeouts or Errors:

Network Congestion or Outages: If there's a significant amount of traffic on the network or an outright network outage, your ping or traceroute command may time out or return an error because it couldn't reach the target IP address.

Firewall Settings or Network Policies: Some networks or servers block ICMP packets, which are used by both ping and traceroute, as part of their security settings. If ICMP packets are being blocked, your ping or traceroute command may return an error or no response.

Getting a timeout or error response doesn't necessarily mean there's a problem with your connection – it might be an issue with the server you're trying to reach or somewhere along the network path between you and that server.

Uses:

Ping and traceroute are essential tools for troubleshooting internet connection problems.

Identifying Connection Issues: By using ping, you can quickly check if you can reach a certain IP address or website, which can help identify if the problem lies with your local network or with the server you're trying to reach.

Identifying the Source of Delays: By using traceroute, you can identify at which hop along the path your packets are being delayed or lost. This can help identify if an ISP is having issues, or if the server you're trying to reach is under high load.

AI and its relation to the concepts of information technology

 I chose A.I as my tech topic. AI and its relation to the concepts of information technology and computer science, including the history of computers: Artificial Intelligence can be traced back to the earliest computers, where pioneers like Alan Turing posed questions about machine intelligence (Turing, 1950). (Side note, did you know Alan Turing was arrested and chemically castrated for being a homosexual and all of that after his service in helping crack the enigma code the Germans were using to disguise their communications in World War 2 ultimately saving hundreds of thousands of lives?) The advent of digital computers laid the foundation for AI, creating the possibility for a machine to simulate human reasoning. This is deeply connected to the central tenets of computer science, which involves problem-solving, algorithmic thinking, and the efficient use of computational resources (Brookshear & Brylow, 2020). Reliance on the major hardware components and functions of a mode...

Understanding Java Installation and Object-Oriented Design Principles

Understanding Java Installation and Object-Oriented Design Principles Java Installation Simplified Java is a programming language that is essential for modern software development. Before you begin writing code, you'll need the Java Development Kit (JDK). The JDK is a software bundle that equips you with tools to develop and execute Java applications. While Oracle is a well-known distributor of JDK, Eclipse also offers an open-source version known as Eclipse Temurin, which you can download and install.  JDK (Java Development Kit): The JDK is a software development kit used to develop Java applications. It is an implementation of either the Java Platform, Standard Edition; Java Platform, Enterprise Edition; or Java Platform, Micro Edition platforms released by Oracle in the form of a binary product aimed at Java developers. It includes the Java Runtime Environment (JRE), an interpreter/loader (Java), a compiler (javac), an archiver (jar), a documentation generator (Javadoc) and othe...

Week 3 Post 1 Revision

 Computers store data on hard drives and removable drives using a hierarchical system. The hierarchical system consists of the File System which is the overall structure that a disk drive uses to store, retrieve, and organize data. Following the File System is the Directories/Folders, they act as containers for files and other directories. Directories can be nested within each other to create subdirectories. Lastly is the Files themselves, a file can contain any type of data and is stored in a directory.  My current backup plan was put in place after losing countless personal files after I had them all stored locally on my cellphone and said cellphone was dropped in the ocean. I have 3 copies of any and all-important information i.e., bank statements, military record, medical documents, and any documents pertaining to anything currently being financed just to name a few. Three copies on my cellphone which is backed up to the cloud and can be remotely wiped thanks to AVG antivi...
