USB or universal serial bus has been around since the mid-nineties. Although the technology is ubiquitous, people are still confused by some USB types and limitations. I’ll admit it can be confusing, but I’m glad I no longer have to wrestle with parallel and serial ports. I’ll explain the differences and tell you how to find out which version you’re using.
Recently, I met a friend who looked stressed. He returned home from work only to find out that someone had broken into his online accounts. Naturally, he was concerned about the data, but also the amount of time it would take to fix the problem. I told him an easy way to reduce the risk of account breaches is to use something called “two factor authentication” or 2FA. But, it has some issues if you’re not careful.
