Week 8 – BSIT220-T301 Network Mgmt & Infrastructure

    IPv4, with its 32-bit address space, can only accommodate around 4.3 billion unique IP addresses. As the number of internet-connected devices explodes globally, IPv4 addresses are rapidly depleting. IPv6, with its 128-bit address space, provides an astronomical number of unique addresses (2^128), ensuring the continued growth of the internet and supporting the vast array of devices, from smartphones and laptops to IoT devices and more.

 IPv6 Features and Advantages:

 Expanded Address Space: The most prominent feature of IPv6 is its expansive address space. This enables the allocation of unique addresses to an exponentially increasing number of devices, eliminating the concerns of IPv4 address exhaustion.

 Efficient Routing and Network Performance: IPv6 simplifies the routing process by reducing the size of routing tables. This efficiency not only enhances network performance but also decreases the burden on internet infrastructure, resulting in faster and more reliable connections.

 Improved Security: IPv6 incorporates built-in security features, such as IPsec (Internet Protocol Security), which was an optional add-on in IPv4. IPsec provides end-to-end encryption, authentication, and integrity, contributing to a more secure and private communication environment.

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.

You want to keep your PC clean, and I am going to tell you how to keep it clean and make sure you keep all of your important data. First off you want to start by backing up all of your important data; you can either use a external hard drive or one drive, I would suggest an external hard drive then you have a spare copy of your data incase your computer crashes. Next up go through the programs you are not using anymore, and fully install and delete those. Another good way of cleaning up your PC is clearing the temp files, or temporary files, these can be found by searching the C: drive. Up next you want to run any updates you need; this will boost your performance and make run things smoothly. Then you can put your data back on you computer and organize it to your liking. 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.
