We live in a hurry-up world.
There's the person behind you in traffic who leans on the horn if your brake lights don't go dark during the nanosecond that the traffic light is transitioning from red to green. There's the one behind you in the self-checkout lane who does the heavy sigh and eye roll bit because you must take the time to dislodge your rewards card from your wallet so you can start scanning your groceries (you knew you should have installed that rewards card app on your smart phone). Oh, and then there's the person who blows past you at the speed of light on a single-lane stretch of highway only to find you puttering up behind them at the next clogged intersection. You no doubt chuckle quietly to yourself as you await the go signal on such an occasion because you know that you've covered the same amount of distance and arrived at a simultaneous point with the speed demon, but at a lower fuel cost.

Deciphering the Alphabet Soup of the 802.11 Standards

Let's see. If you overlay the 802.11a standard with 802.11b standard and subtract the 5-gigahertz (GHz) band, you get an approximate 802.11g standard. Then add back the 5-GHz band, add four multiple-input and multiple-output (MIMO) streams to get the 802.11n standard. Subtract the 2.4-GHz band, multiply the available MIMO streams by 2, and you get the 802.11ac standard.
The TSHOOT Tree

I've taken dozens of certification exams over the past 15 years, and I've created practice exams for most of them. But if I had to choose the one that was the most interesting to take and to create, I would have to choose Cisco's 642-832 TSHOOT exam, part of the Cisco Certified Network Professional (CCNP) Routing and Switching track.
What makes a solid-state drive faster?

What makes a solid-state drive faster?
Immobility.
Yep, it’s really as simple as that.
I don’t mean that in a portability sort of way; solid-state drives (SSDs) are quite portable! An SSD doesn’t move on the inside, and this lack of movement is what helps it perform so much faster than other storage devices. Having said that, it really wouldn’t be much of a blog post if I didn’t attempt to paint you some sort of similitude packed with a sampling of picturesque details that will assist you in a greater depth of understanding of just how this all works…right?
