From NICs to switches, modern networks are comprised of many devices. As it’s important for IT pros to know a router from a gateway, I put together a quick pop quiz on basic network devices.
Note: Unfortunately, our poll tool, which I use to create each pop quiz, doesn’t let me indicate a correct answer after each question. To keep from giving away the answers before everyone has a chance to test his/her knowledge, and ruining all the fun, I’ve published the answers on the second page of this blog post. I encourage everyone to answer all the questions before looking at the second page or using your favorite search engine to find the answers.
