In addition to knowledge of multiple programming languages, computer programmers must be detail-oriented. When it comes to writing and debugging code, even one misplaced character can cause a program to malfunction. Being a critical thinker is essential, as there are usually multiple ways to approach a programming problem, some more efficient or elegant than others. Programmers are also focused and patient, since they may be tasked with writing line after line of code for long periods of time or conducting several tests to properly evaluate the quality and performance of a program. Because computer programmers are often required to write code based on a client or employer's request, it's important that they be active listeners and strong communicators. Lastly, an understanding of how people typically use computers helps when designing user interfaces. Programmers can earn certifications in both languages and platforms. Most major systems vendors also offer certifications. For example, Oracle and Microsoft offer exams that benchmark programmers' abilities in specific areas.
Brain-Computer Interfaces Are Coming. Will We Be Ready? Humans controlling machines with their minds may sound like something from a sci-fi movie, but it’s becoming a reality through brain-computer interfaces. Understanding this emerging technology now can help ensure that effective policies are in place before BCI becomes a part of everyday life. Brain-computer interface technology is already in development. RAND researchers are exploring the potential risks and opportunities that BCI could bring. Three drones lift off, filling the air with their telltale buzz. They slowly sail upward as a fleet-evenly spaced and level-and then hover aloft. On the ground, the pilot isn't holding a remote control. In fact, he isn't holding anything. He's just sitting there calmly, controlling the drones with his mind. This isn't science fiction. In the clip, a mechanical engineering Ph.D. Arizona State University (ASU) sports an odd piece of headwear. It looks a bit like a swim cap, but with nearly 130 colorful sensors that detect the student's brain waves.

HDTVs and computer monitors can have very different response times. HDTVs tend to prioritize richer colors, higher contrast, and wider viewing angles-all of which lend to a longer response time. Computer monitors tend to drop some of the image processing and viewing angles for faster response times. If you use a display with a slower response time, you may see “ghosting” in fast-paced video and gaming sequences. Also pay attention to the type and number of ports. This is only one of two port areas on an LG TV. Many TVs offer ports nearer the side as well for the sake of easy access. Some HDTVs have a “game mode” setting, which cuts some of the image processing to improve both input lag and response time. If you plan to play PC games on your TV, definitely dig around in your HDTV’s options to see if it has this feature.
Video - A type of data that is represented as a series of still images, each one slightly different than the other. It’s basically like having an animation without the movement seen on television or movies. Most videos are recorded at 30 fps (frames per second), which means that you will see each frame for 1/30th of a second before it updates to show another frame. This general knowledge section has the most terms out of all the sections, but don’t let it intimidate you! I placed them here because they are basic things you need to know for troubleshooting purposes; not necessarily related to computers. You may find these definitions helpful when dealing with other types of consumer electronics besides computers as well. Desktop - This is the main area where all of your computer’s items and icons are located. Instead of starting at the desktop with a monitor, keyboard and mouse, you can also configure your environment to start with a full-screen window instead which will be explained in more detail below.
