 When it comes to networks, it becomes pretty scary to see or hear that a network is down. Checking to make sure the physical side of the network is an important step in troubleshooting network issues. Are there issues with the network interface cards (NIC)? Is it a software problem over hardware? If one application is having difficulties connecting to the network but everything else is connecting to it fine, that is a sure sign that it is a software problem and not a hardware problem. Are there only certain computers unable to connect to the network while all the others can connect? That is normally a sign of hardware issues. It could be that the NIC card in these workstations have gone out, or it could be an issue with cabling. Using network cable testers in your telecommunications room can help you determine if there are any issues with the cabling. If you are able to find faulty cabling, you then know where to start looking for the area of cabling that needs to be replaced.

 Quad-level cell SSD’s or QLC SSD store four bits of data per cell. The previous predecessors are single-level, multi-level, and triple-level cells which offer one, two, and three bits per cell respectively. Is QLC SSD a better choice than the previous models? The only advantages I am seeing for QLC SSD is a lower total cost of ownership, reduced data center footprint, and increase in capacity. There are however a lot of downsides to them that I am not sure I would be comfortable with. That have less durability than previous models and makes them less reliable. Since QLC SSD have to check double the amount of threshold voltages compared to the TLC SSD they also write slower than the previous models. All in all, I feel like the QLC SSD is not going to be the best option for someone who constantly needs to rewrite over old data constantly.   References: What is QLC SSD: Pure Storage .

 In our day to day lives ethernet has become a staple to all users and can be found across most homes. Not only is it used for connecting computers in a local area network (LAN), but it is also used to connect devices to the internet which is considered to be the largest Wide Area Network (WAN). I never realized until I started taking networking classes that ethernet cables have been around for a very long time. Today you can get ethernet cables to deliver speeds of up to 40 GB/s. I always assumed that ethernet cables were used to strictly connect devices to the internet and never thought about how they are used in a network setting.   With that in mind, I was surprised at first when I found out that there were ethernet cables that could allow up to 40 GB/s speeds because the internet doesn’t go that fast. It makes total sense now though that businesses, especially data centers, could benefit from extremely high speed of data transfer inside their networks.

 When choosing memory for your computer, whether you are building a new one or upgrading an old one, it is hard to determine which is the best route to go. Is DDR4 still a viable option or should you work on making your PC DDR5 compatible. New and emerging technologies are very exciting but are they worth the initial cost of getting the newest in technological advancements? DDR4 is still a very reliable and great RAM for the majority of users. DDR5 RAM leaves DDR4 RAM eating its dust when it comes to speed in data transfer. DDR5’s transfer speed can get up to 38.4 GB/s while DDR4 is topped out at 25.6 GB/s. The latency is worse in DDR5 over DDR4. While DDR5 can transfer data faster than DDR4, DDR4 RAM can access the information quicker. DDR5 compatible components also cost way more than DDR4 compatible components. As it currently stands, you are better off with using DDR4 RAM until DDR5 becomes more mainstream and the price of it lowers. Once it becomes more mainstreams the lat...

       When I was a lot younger, I never realized there was a difference in ethernet cables. One day I remember sitting there talking to a friend of mine when I mentioned that even though I paid for good internet, I was not seeing the speeds that I should be seeing. He mentioned to me that there are different types of ethernet cables and that I could have an old, outdated cable which could be bottlenecking my speeds.                 Currently, the best ethernet cable available is Cat 8 ethernet. This is best used in data centers where the speed of the data transfer matters the most. There is no reason to not upgrade to Cat 8 ethernet if you are using old ethernet cables as it allows for more data to be transferred quickly.

 Windows has had some ups and downs in the past when it comes to launching new Operating Systems. In October of 2021, Windows launched their latest operating system, Windows 11. They haven’t really promoted the new operating system that much because I spend a lot of time on my computer and am just now hearing about it. A lot of people would have to go out and get new PC’s or upgrade their current ones in order to run Windows 11. Personally, one of the coolest new features offered in Windows 11 is what they are calling Snap Layouts. It allows you to quickly set a layout for how apps appear on your screen. These layouts are saved on the app taskbar and do not have to be re-created each time. Some of their default apps are getting major overhauls and even gaining some abilities that paid apps do not offer. Microsoft is pushing their Teams app by having it installed and available on the taskbar as they are wanting to reach out to everyone and not just be focused on workplace uses. ...
