For the last 80 years, basically, all computers have worked based on the same principle. They feature components that have series of electrical circuits consisting of many transistors. The values of these transistors and circuits can be whether 1 or 0 – it can be on or off. You can imagine it like a light bulb being lit and not lit. Now imagine that you can dim this light bulb however you want. Now imagine that you can dim this light bulb darker and brighter, even more, it can be lit and not lit at the same time. Welcome to quantum computing! Quantum mechanics has an enormous potential, offering millions of times faster performance than convention computing. Can we harness this potential and use quantum computers in our homes, game and work on them? Most likely it’s too early to speak about the massive commercial use of quantum computers. However, the good news is – we can build them, now we just need to make them run. A brief look into quantum mechanics Quantum … [Read more...] about Quantum computing, is it the future for desktop PCs?
Things can go wrong, even if you’re using the best external hard drive on the planet. One of the most common problems that can happen is when your external HDD won’t appear on your list of devices. That can be a nightmare for some – especially if your hard drive contains a lot of important information and you need it right away. What Could Have Gone Wrong?

Another rare original Apple computer is hitting the auction block and while its hardware isn't a marvel of speed by today's standards, it's still expected to fetch about as much as the going price for a snazzy new supercar. Steve Jobs and Steve Wozniak produced about 200 Apple-1 computers in the mid-1970s and around 60 of those are known to still exist today. Every so often one pops up at auction and manages to sell for a price that could easily purchase a home in most locations. RR Auctions is preparing to take bids on a functioning, late "Byte Shop"-style Apple-1 model, with the expectation that it will go for more than $300,000 (about £233,553, AU$409.500). That's about the same you can expect to pay for the speedy and sexy 2019 Aston Martin DBS Superleggera, among many, many other awesome things.The Byte Shop Apple-1 comes from a batch of 50 computers made by Jobs and Wozniak specifically for the Byte Shop in Mountain View, California, one of the first personal computer … [Read more...] about Working Apple-1 computer could sell for price of a supercar
How to backup computer to external hard drive – three simple steps Most people never think about the importance of backing up their data until they lose an important file, and by then it’s too late. There is no reason for this to happen to you, considering that it is very easy to back up your files to a portable hard drive. There are two types of external hard drives: desktop drives that need to be placed near the computer to be backed up and require a power adapter, and portable drives that are small enough to be placed in a shirt pocket and generally connect to your computer using USB 2.0/3.0 ports or Firewire for Mac users. Desktop drives mostly have capacities of up to 6TB although some manufacturers may put two drives in a chassis to greatly increase storage capacity (i.e. two 4TB drives for a total 8TB), while notebook-style drives are commonly offered with capacities of 500GB to 1TB. No matter which type you opt for, get one that has twice the … [Read more...] about How to backup computer to external hard drive
