Name resolution Breakdown Name Resolution : The process of converting domain names (like www.google.com ) into IP addresses (e.g., 192.168.1.100). Why It's Important : Computers communicate using IP addresses, so name resolution is essential for network interaction. How It Works : Browser checks the local hosts file (personal address book) first. If the domain is not found, the computer queries a DNS server (like an internet librarian). DNS server sends back the IP address, allowing the computer to connect to the website. Methods of Name Resolution : Hosts file : Simple, but requires manual updates. DNS : A distributed system that efficiently handles domain-to-IP translation. Multicast DNS : Used for automatic name discovery in local networks. Link-Local Multicast Name Resolution : A protocol specific to Windows systems. DNS Security : Critical for the internet's function; attacks can disrupt access for many users. DNS queries can reveal browsing history, raising privacy conc...

 Week 5 - Whois and TracerRT      This week was little challenging. Learning to read tracer RT's and make sense of the data that is provided was a challenge. I did learn a lot seeing the various companies researched by fellow students and seeing how many registrars are really out in the world. I think it is very interesting the amount of data and information that can be pulled from running a tracer RT. The amount of hops, timeouts that occur and the various IP address a simple search goes through is amazing.      The Whois provides key data on companies. Who is their registrar, office locations,  when domains were first acquired and when they will expire unless renewed, are all points of data that can be view on a whois report.

Week 4 Blog Post Types of cabling used in networks Stranded core cabling consists of multiple smaller wires twisted or braided together to form a single conductor. This design offers increased flexibility and durability, making it ideal for applications where the cable needs to be frequently moved or bent, such as in portable devices or environments with constant movement. The individual strands help distribute stress and prevent breakage over time. However, stranded cables tend to have slightly higher electrical resistance and can be more expensive to manufacture than solid core cables. While they are less suitable for long-distance transmission due to their higher resistance, stranded cables are commonly used in Ethernet networking, audio systems, and power distribution, where flexibility is essential. Solid core cabling features a single, solid conductor, typically made of copper, and is used for transmitting electrical signals or power. It provides better conductivity and lower res...

 Week 3 Blog Post - Ethernet, Hubs and Switches Switches and hubs were some of the easiest networking concepts for me to grasp, but they also demonstrate how far technology has advanced. Hubs, which broadcast data to all devices, were a step forward in their time but slowed networks down and lacked security. Switches improved on this by sending data only to the intended device, boosting speed and privacy. They also introduced features like the Spanning Tree Protocol to prevent connection issues. This evolution highlights the critical role of cabling as the backbone of any network. With options like fiber optics, Cat 5e, and S/FTP, choosing the right cable is essential, though sorting through similar types like UTP and FTP can be challenging. The progress from early standards to technologies like Gigabit and even Fiber optics is crazy. The shift from basic hubs to intelligent switches has made networks faster, smarter, and more efficient, powering everything from video streaming t...

I knew that cables and connectors existed, but I had no idea there were so many different types. Twisted pair cables are commonly used because they’re easy to handle and provide reliable speeds over short distances. Then there are fiber optic cables, which I’m familiar with since I use them for my internet and the speed is impressive. This week, the chapter also covered network architecture and the devices that enable data transmission. Ethernet is a widely used method for devices to connect and share information. Devices like hubs, switches, and routers play a crucial role in directing the data traffic. Hubs send data to all devices, while switches are more efficient, routing data only to the intended recipient. Routers connect networks such as  home networks or office networks to the internet. Understanding how these devices work together is key to effective network management and troubleshooting.

  Hello! My name is Mike, and I’m excited to share a bit about myself as I embark on this journey. After spending time in the world of audio production, I’m making the transition to a degree in Information Technology, and I’m eager to dive into all the new opportunities this field has to offer. In today’s digital age, IT plays an integral role in nearly every industry, and it’s a field that’s constantly evolving. From software development to cybersecurity and everything in between, the world of IT is constantly changing and opening new opportunities. I’m fascinated by the idea of working behind the scenes to ensure that systems are running smoothly, data is secure, and people have the tools they need to succeed in an increasingly connected world. As I begin my studies in Information Technology, I’m already excited to dive deep into areas like networking, AI, and digital forensics. Whether it’s building solutions to everyday problems or working on the cutting-edge technologies that ...
