Important Things to Keep in Mind when Designing Networks Don’t skip the actual design phase: When you’re initially at network planning and design you might think it’s simple to link all your devices together. That might be true if you only have a handful of things to connect, but everything that is added to or removed from the network will affect your network’s performance, so as you have more devices it becomes more complex and more important that you get things right. Plan: Key part of network planning and design is selecting systems that will grow with your business. Embed security in your design: Network security is no longer something that can be considered as a bolt-on or afterthought. It is instead something that needs to be embedded at the very heart of your network design.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
