Cyber security is the practice of ensuring the integrity, confidentiality and availability of information. It represents the ability to defend against and recover from accidents like hard drive failures or power outages, and from attacks by adversaries. The latter includes everyone from script kiddies to hackers and criminal groups capable of executing advanced persistent threats, and they pose serious threats to the enterprise. Security should be top of mind across the enterprise, and come come with a mandate from senior management. The fragility of the information world we now live in also demands strong cyber security standards and that employees are properly trained. All code, for example, has bugs, and some of those bugs are security flaws. Develops are only human, after all. All companies will experience some kind of cyber attack, even if strong controls are in place. An attacker will always exploit the weakest link, and many attacks are easily preventable by performing basic security tasks, sometimes referred to as "cyber hygiene." A surgeon would never eneter an operating room without washing their hands first. Likewise, an enterprise has a duty to perform the basic elements of cyber security care such as maintaining strong authentication practices and not storing sensitive data where it is openly accesible.
Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men - meaning, no banks! Bitcoin can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. But much of the hype is about getting rich by traading it. The price of bitcoin skyrocketed into the thousands in 2017. Bitcoins can be used to buy merchandise anonymously. In addition, international payments are easy and cheap because bitcoins are not tied to any country or subject to regulation. Small businesses may like them because there are no credit card fees. Some people just buy bitcoins as an investment, hoping they'll go up in value. Many marketplaces called "bitcoin exchanges" allow people to buy or sell bitcoins using different currencies. Coinbase is a leading exchange, along with Bitstamp and Bitfinex. But security can be a concern: bicoins worth tens of millions of dollars were stolen from Bitfinex when it was hacked in 2016.
The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with everyone in order to create an image. To do this, it needs a translator -- something to take binary data from CPU and turn it into a picture you can see. Unless a computer has graphics capability built into the motherboard, that translation takes place on the graphics card. A graphics card's job is complex, but its principles and components are easy to understand. In this article, we will look at the basic parts of a video card and what they do. We'll also examine the factors that work together to make a fast, efficient graphics card. Think of a computer as a company with its own art department. When people in the company want a piece of artwork, they send a request to the art department. The art department decides how to create the image and then puts it on paper. The end result is that someone's idea becomes an actual, viewable picture. Similarily, a graphics card works along the same principles. The CPU, working in conjunction with software applications, sends information about the image to the graphics card. The graphics card decides how to use the pixels on the screen to create the image. It then sends that information to the monitor through cable.
