  Ever since the creation of computers people have been fascinated by how small and powerful these devices can become.   The first mobile station with an 8” screen and weighing 40lbs to the mobile devices we have now that can run multiple simultaneous tasks at all times once, we are seeing devices with fewer drawbacks. Even while being more practical there are still some smaller issues that modern devices face. Much like in the older days powering devices is an issue, most devices can run a few hours before needing a charge, also the use of storage is limited in a small form factor. Even with the first two items working the issue of heat is also another element to balance, devices are not as simple as most think. Finally, the ability to drop or break these tiny devices is much more predominant than in typical laptops or even desktop computers. Sakshi.

Within networks there are many devices to connect a simple phone to Wi-Fi or connecting a hardline gaming computer. With most internet arriving to the house with coaxial connection it makes it easier to terminate and connect to a modulator/demodulator or “modem” for short. The connection then is typically routed via a Cat 5 or newer cable utilizing either SFP or in most homes the use of a RJ45 connector. Then it will go to the router, basically the brains of the internet, most home routers include a basic DHCP and DNS server that will point to a uplink DNS server. The following device may be integrated with the router, the Wi-Fi or access point. Access points will transmit a connection using the 802.11A,B,N,G,AC,AX connections. Melnick, J. (2019, January 8).

Hypervisors are devices that enable other devices or applications to run, imagine a opensource old game that cannot run on any modern OS, one will need to purchase a older device that the software and hardware to run that single game. Now imagine having a system that only has the parts needed for that game to run and put it all in a box, this is the power of virtualization. Virtualization also relies on already running software and hardware depending on the version. If a system is created to function as a purely virtual machines type 1 would be the best. Type 1 hypervisor runs directly on the hardware whereas the type 2 run on top of an already installed OS. It is all about what it will be used for. Server admins like using virtualization due to how efficient the hardware can be. Imagine managing 20 servers and all the equipment and time needed to manage them, now imagine that it is all in one or two servers still functioning as well as it did when separated. This will reduce cost and ...

  Within the article is shares to backup all data, although this is a good idea if a device is slow, it is wise to figure out why it is slow first prior to removing everything and adding it back. Let’s say that there is malware on the current device, by backing everything up the malware may be backed up. Instead of creating a local backup maybe uploading to a cloud provider such as OneDrive that will scan and keep all the files safe while removing any unwanted malware may be a good idea, additionally to re-install and remove all files will clear old log files and old cache files that are likely not helping things.     Peers, N.

When I built my first computer I had some issues with low frame counts on a computer that had all the right things to handle games, one of my first things that I came across when looking for a solution was to enable “gamer mode” by installing the “Unlimited Performance” option in control panel. After configuring the settings, I saw a noticeable improvement as well as a higher clock speed, and louder fans. This was my first interaction with how settings can affect performance. In the following weeks I learned to tinker with both computer policies and registry edits that will disable useless items and remove graphical add-ins that eat away at my sweet, sweet frames. Although this is still around Windows 11 will adapt the workload to what is needed and can offer much higher speeds while balancing a battery when in a laptop.

  Within my few years of supporting operating systems, I have came across one issue more than any else, DRIVERS! Yes, the software or firmware that is installed that tells the computer on how to interact with the hardware is often the leading cause to PC issues for HP and Dell computer based off my experience. I mostly work with Windows products, so it is easy for this issue to be resolved by rolling back drivers or by looking for new ones, however on Linux many times it is not as easy. Just today the audio refused to work with one of my client computers and after some diagnosing a simple reset of the device or re-installing the audio drivers fixed it, this is common for Wi-Fi drivers as well. Based off of the Wikipedia link in for week 4, I came across how the drivers are developed. There is many terms that I have never needed to know prior to learning about the development stages, and frankly I am glad that is not what I do.
