Finishing my Computer Science Degree
Hi Everybody! I just wanted everyone to know that even though I haven’t posted a new blog post in a while or written about my online router simulator it isn’t because I’ve neglected this website or more importantly YOU my readers. I care a lot about you guys. I know that getting your CCNA is [...]

The beauty of this is that, if designed properly, redundant links can quickly be found with out the network going down or users even knowing there is an issue. [...]

While there are some new topics about it that I didn’t learn when preparing for my CCNA exam, everything that I’m [...]

And not just technology is general, but specifically computers and networking. According to the Bureau of Labor Statistics, all computer-related sales are expected to grow faster than any other job through [...]

Obviously there is still a lot of work to do, but there currently is a lot of functionality to help [...]
