Week 5 BSIT220-T301 Network Mgmt & Infrastructure

            Traceroute is a command-line tool designed to trace the route that packets of data take from a source to a destination. This information helps identify network issues, pinpoint delays, and understand the topology of the internet between the two points. The command is available on most operating systems, including Linux, macOS, and Windows. Traceroute operates by sending a series of packets toward the target destination with each packet containing a Time-to-Live (TTL) value. The TTL value represents the number of hops (routers or nodes) the packet is allowed to traverse before being discarded. As the packet reaches each hop, the TTL is decremented, and the hop sends back an ICMP Time Exceeded message when the TTL reaches zero. This process repeats, with the TTL incrementing for each subsequent batch of packets until the destination is reached. By analyzing the sequence of hops and their round-trip times (RTT), traceroute generates a comprehensive map of the network path taken by the data.

Week 3 Posting - RAM Making Your Everyday Tasks Easier

          Random Access Memory is your computer’s short-term memory, unlike the long-term memory with a hard drive or SSD, RAM stores date temporality while your computer is running. When you open an application or a file, your computer loads it into RAM for quick access. This allows your computer to do tasks faster because accessing data from the RAM is much quicker than fetching it from storage. The more RAM you have the more applications and data your computer can handle without slowing down. RAM is good for multitasking, gaming, video editing, and resource-intensive tasks. In conclusion, RAM is kind of the unsung hero of your computer, enabling it to handle tasks swiftly and efficiently. Understanding its significance can help you make informed decisions about upgrading your system’s memory for a better computer experience.

There are many ways to clean up your PC this is just a process I run...

Week 1 - BSIT220-T301 Network Mgmt & Infrastructure

                  This is my 2 nd blog I have done, and my 13 th blog post I have ever done, did one a week in my previous class here at Bellevue. I would say I have some knowledge about the Network+ and Network models from my previous college. At Southeast Tech we got to work on all sorts of network equipment and troubleshoot it as well. We worked on servers, routers, switches, access points, and more. We got to build networks on server racks and ping and use all sorts of commands, so I have a nice background with information, and I am excited to learn more about that as well as the Network+ certification and what it takes to get that.
