SSD is the commonly used abbreviation that stands for solid state drive . Solid state drives are used for data storage just like a traditional computer hard drive (which are commonly referred to as HDDs – you can find more info on that in the next section just below). Even if you\’re not familiar with the terminology, you are probably well familiar with how SSD is used, in things like thumb drives or USB memory sticks. These are just miniature versions of solid state drives. Solid state technology doesn’t use any moving mechanical parts, but instead relies on flash technology. That means no spinning disks and no humming or whirring sounds when an SSD is doing its thing. And it also means dramatically lower latency times. In other words, a solid state drive can load data lightning fast. The Pros and Cons of SSD ·          SSD is faster. Much faster.

Blue light has a dark side

5G Is Real Verizon Wireless has won the race to 5G—sort of. On October 1, Verizon launched its "5G" home service in Houston, Indianapolis, Los Angeles  and  Sacramento, establishing equivocal bragging rights and setting off a domino run of 5G network launches that will continue through next spring. That first network isn't actually the real, global mobile standard for 5G. The first one of those will likely be AT&T's network, coming by the end of the year. (Verizon plans to switch to the global standard next year, swapping out equipment at no cost to existing customers.) This all means you're about to see the marketing for 5G get ramped up quite a lot, and so it's good to know what everyone's actually talking about. 5G stands for fifth-generation cellular wireless, and the initial standards for it were set at the end of 2017. But a standard doesn't mean that all 5G will work the same—or that we even know what applications 5G will e...

The History of Mobile Phones From 1973 To 2008: The Handsets That Made It ALL Happen All the mobile phones that mattered from the first Nokia handset right up to the iPhone 3G A LOT can happen in 40 years. But when it comes to technology, 40-years is like going back to the days of Moses or the Roman Empire. Case in point: the mobile phone –– and, more recently, the rise of mobile internet communications, social networks and super-fast internet. But what were the phones that made it happen; who were the pioneering brands that made today's handsets possible; and which phone, out of the thousands launched since the 1980s, was the most important? Answer: quite a few. But first: a history lesson.  The world’s first mobile phone call was made on April 3, 1973, when Martin Cooper, a senior engineer at Motorola, called a rival telecommunications company and informed them he was speaking via a mobile phone. The phone Cooper used, if you cou...
