Statistics shows that an average personal computer is used for only four hours a day and left idle for about 5.5 hours. This shows that computers are not always in use majority of time they are kept on. However, computer systems usually increase the electricity expenses hence there is a need to use a set of features that diminish power consumption by computers known as computer power management.

32TYPES OF COMPUTER POWER MANAGEMENT.Most of the computers when purchased have energy saving features installed but they have to be turn on so as to function as intended. There are different types of these power management and they include;
1. System standby or sleep. This is a technique commonly applied when the computer is not in use for one hour or even more. It helps to slow down the clock rate of the CPU and also spin down the hard disk.
2. Turning off or dimming the monitor. When you are not using the computer for about 30-60 minutes, it is advisable to always turn off the monitor because this will diminish the beam control power thereby assists in saving energy.
3. System shut down or power off. For example; at the end of work day, it is not good to leave the computer on until the next work day or even during weekends. It is good to turn off these computers so as to cut on costs.
4. Turning off hard disks. This will help save energy though in little amount.

DOES POWER MANAGEMENT AFFECT COMPUTERS NEGATIVELY?There are some common myths that turning on and off a computer will end up reducing its life span. Moreover, it is said that turning on a computer requires a lot of extra energy. This is not true. Surprisingly, turning off the computer will even help increase its life span because heat is always produced from the central processing unit(CPU) hence shutting down will help it to cool down and will also give time for the moving parts like cooling fans and spinning hard disks to rest.

IS THERE ANY DRAWBACK ASSOCIATED WITH POWER MANAGEMENT?It is well known time is money, hence fully turned off computers will always take a lot of time to bring it back to its normal operational status. Therefore, it is advisable to turn off the PC when you are away for a long period of time like at the end of work day. Also, using sleeping mode is suitable when the PC is idle for thirty to sixty minutes.
Apply these methods today and save money spent on electricity expenses.

All about sound quality

31Sound quality is a difficult thing to find, especially when dealing with computers, and that is only if you can even recognize it when you hear it. Issues of sound quality are very subjective, and delivering a comprehensive answer to the question of best sound quality is all but impossible, not when you take into account the diversity of answers that are bound to emerge.

For a few years now, the debate of sound has often devolved into an onboard sound VS Sound cards argument. It is because both options bring so much to the table that choosing one over the other is so difficult. Speaking strictly about sound quality though, sound cards have an advantage over integrated sound from the computer.

However this advantage begins to fade when you consider the additional costs you have to incur to acquire the sound card, especially when it is so difficult to determine if the availed quality is worth the additional cost.

For most people, this argument tends to come down to individual preferences and interests; though it can be argued that there is so much more to acquiring proper sound quality than merely investing in a dedicated sound device.

Computes that boast the best sound quality more often than not have to compliment the right sound card with headphones or speakers of noteworthy quality. And the format of the audio being listened to also matters; there is a noticeable difference between the quality of compressed audio files and uncompressed audio files.

This is where the issue of need comes into play; if you do not watch movies or play video games or really listen to high quality sound files (which haven’t been compressed), then you should be able to get the best out of your computer depending on just the onboard sound.

In fact there is little point in spending several hundred dollars buying a sound card for the sake of listening to MP3 audio files with a relatively cheap set of ear buds. In such cases, you are never going to even notice the difference between onboard sound and sound card quality.

However if you intend to listen to clean audio files that haven’t been tampered with, then a decent sound card and a set of speakers or headphones worth a few hundred dollars will make for quite the stark difference in the quality of your computer’s sound.

In other words, there is no one answer or solution capable of satisfying every individual’s need for quality sound on their computer, not when taking into account individual tastes and financial issues.
