What are Bitcoins?

Bitcoin is a digital peer-to-peer currency system that provides a decentralized method for performing transactions.

Bitcoins (BTC) are also the name of the unit of currency. The Bitcoin protocol is based off a paper by Satoshi Nakamoto called “Bitcoin: A Peer-to-Peer Electronic Cash System” that is designed to allow monetary transactions between users without a central authority like a bank or services like PayPal.

Avoiding a central authority allows you to be anonymous, can lower the cost of transactions, prevents your account from being frozen, and lowers the entry barrier for new users. Of course, without a central authority, that leaves nobody to make sure users are not counterfeiting or double-spending their money, right? The Bitcoin protocol protects against this using its peer-to-peer technology to verify each transaction and make sure only the authorized users are transferring their own bitcoins.

“…When you make a transaction, it is announced to everyone on the network, so everyone knows your wallet made a transaction to another wallet to prevent double-spending.”

4 Technology Trends That Could Affect You

Technology not only continues to be a driving force in our everyday lives, but since we’ve become so dependent on it, we should be mindful of the trends that could directly impact how we live, attend classes and do business.

The following trends address the continuous evolution of digital technology and how you can adapt and benefit (by saving money!) from knowing what technology can help (or not help) you.

Computing Horsepower

It’s safe to say that computers built in the last 5-6 years still have relatively enough horsepower to help people plow through everyday tasks like email, MS Word/Excel, Facebook and iTunes. However, one trend that could help consumers who are looking to buy a new rig is the advent of integrating the graphics card and the CPU into one single package. Intel already has this technology, called Sandy Bridge, in which the graphics card is inside their CPU. (Intel Core i3- i5-i7 processors)

Unfortunately, Intel’s flavor (HD 3000 series) leaves much to be desired. A cheaper alternative, AMD’s Fusion APU (Accelerated Processing Unit) has better built-in graphics (Radeon 6000 series). What this means for consumers is that if you’re looking to build a new system and your multimedia needs are moderate, opting for an Intel Sandy Bridge or AMD APU can save you from spending extra on a physical graphics card. It also provides a smaller computer chassis to save space.

In this week’s Tech Tip, we’ll show you some practical techie things that’s will help your student get on the right “techie” footing when they hit the classroom!

The Computer
While it’s always a good idea to check the syllabus for the school or class with their recommendations for the students’ needs, every student undoubtedly needs a good computer! The good news is that you can pick up a very cheap laptop for the price of what you would pay for a decent desktop just a few years ago. Really, for about $350 to $500 dollars you can find a decent machine that will last the whole school year.
