Computer Education


The world is becoming more and more fast paced. Technology has increased so much in the last few years and this trend looks like it will continue. It is so important to keep up with these emerging technologies and the skills that are required to properly use these new gadgets. As anybody can attest to, the nature of our working environments have changed drastically over the last twenty years. While every generation have different work skills that are emphasized, it’s been unprecedented how quickly computer skills have gained prominence in recent years.Think back to just thirty years ago when computers were seen as a fringe technology that were used by the top scientists. After all, computers used to be the size of an entire room. However, computers have become such a vital part of our lives and are particularly important in the workplace. For that reason, many people find that they need to take the proper Computer Education courses to properly stay on the fast track of their career path.Computer education can come in a number of forms. They can be basic courses that will show you how to use a computer or can be complex programs that will teach you a specific computer program. As businesses today move towards storing their data in computers and using computer programs to perform a number of functions, it is so important that you are computer savvy.Are you afraid that your limited computer skills are holding you back from moving forward in your career? Well, you may find that taking a computer education course is the key. After all, many different professions rely on specific computer programs and computer skills that you will need to know. So go on the offensive and learn these computer skills to increase your employability.For other people who are bored with their careers, they may find that taking a computer education course will open the doors to a new career. Many people have found that they have a hidden talent with these computer skills and have greatly improved their careers after taking a computer education class.Another great benefit of taking a computer education course is that it shows your initiative to your employer or potential employers. People respect individuals who are willing to increase their knowledge and by taking a computer education course, you are also making a testament to your personal characteristics. An additional plus with taking a computer education course is that you will be able to fully know how to use a computer.Besides seeping into work culture, computers are used in many people’s personal lives. Whether it’s online banking or writing your own blog, many people have found that the skills that they have learnt from a computer education course has many benefits that can be applied in their personal lives. So if you are looking for a way to improve yourself and to increase your knowledge, you may find that gaining a computer education is the right choice for you!window.google_render_ad();

Choosing a Sound Card: Build Computers
<



Build Computers:Choosing a Sound Card
All modern sound cards are capable of playing back CD quality audio (technically speaking, digital data stored in stereo at 16-bit/44.1KHz). However, sound cards are by no means all equal. The first important distinction is the number of audio outputs that they carry. Older sound cards have just a stereo line out - usually mini-jack socket on the spine of the card. All you need to do is connect this to the input sockets on an amplifier or amplified speakers and you're away. This is fine and dandy for playing back stereo music, but there are many more sonic avenues opened if your sound card has two stereo outputs in the form of two mini-jacks. This opens up the world of so-called 'Surround Sound'.
The idea is simple. You place two speakers in front of you, and two speakers behind. In this way, you can be 'surrounded' by sound. Audio is no longer limited to a stereo plane in front of you - sounds can now be delivered within a 360 degree horizontal plane.
The most obvious application of this is for games - just what we're interested in. If a monster is behind you, the first clue you'll get is the sound of his slavering chops emanating from the rear speakers. Turn round on screen, and the sound will pop round the 360 degree plane to appear in the front speakers.
But the ability of sound cards to enhance otherwise uncolored sound doesn't end there. Creative Labs, progenitor of the ubiquitous SoundBlaster series, has developed a new API (Application Programming Interface) called EAX (Environmental Audio eXtensions). This models the way sound changes depending on its environment: for example, a sound reverberating in a metal tube will sound different from the same noise in a cavern. EAX allows programmers to specify details about the environment that modify the audio outputted by the sound card.
SOUND IN 3DThere are a few other considerations you may need to take into account if blasting aliens is on your agenda. Modern sound cards support what is known as '3D audio'. Without going into too much technical detail, there are a number of APIs (of which the lowest common denominator DirectSound 3D is built into Microsoft's DirectX drivers) that allow programmers to work with directional sound in extremely complex ways. By measuring how the human ear 'filters' sound that comes at us in three dimensions, complex algorithms can be brought to bear in real time that imitate these subtle differences in sound. Game developers can now place sounds horizontally and vertically in full 360 degrees and the API modifies them such that our ear correctly predicts their position. This is even possible with just two speakers, particularly headphones - after all, we have only two ears - though the results are far, far better with four speaker systems.
Many sound cards now have additional outputs besides the front and rear speaker pairs, specifically one for a subwoofer signal and another for the so-called 'centre' speaker. This configuration, known as 5.1 audio (five normal channels plus one subwoofer low frequency channel) is primarily aimed at home cinema fans - with suitable software, your PC can decode full Dolby Digital soundtracks. However, you can usually configure such setups to output to just front and rear speakers, ignoring the centre channel, and additionally using the subwoofer for low frequency in game audio - listen to those explosions rumble!
