Choosing Speaker Audio For Computer

Choosing Speaker Audio For Computer

What computer speakers pick up? - a question that a lot of us, when it comes to audio system. After all, a computer that is devoid of sound - it is a defective computer . He can not listen to music, watch movies, normally play computer games, and more.

Sets the speakers to the computer - a very serious matter, which should be taken seriously. And the ones who disobey - will gain cheap speakers , the sound quality that they will produce will be so substandard that the columns will not name - only certain beeper.

Therefore recommend that you follow these guidelines when choosing speakers for your computer , make sure that your choice was correct and did not have to be sorry after:

First of all you need to decide for what purpose the required column . This is a very important aspect, because for one type of music suitable speakers for computer games - the other, and to see the third film.
If the speaker needs to listen to music, the best place to buy an active type speakers (amplified sound) of the 2.0 (two columns). These columns will be possible to accurately reproduce the sounds of both the low, mid and high tones.

If the speakers are needed, preferably for games , then your choice is to stop on the 2.1 system (one subwoofer and two satellite speakers-) - subwoofer will be responsible for the sounds of low tones, and satellite speakers, respectively - the medium and high. The sum will experience the reality of a sound range of a game.

In the case of video display (as HD) you need speakers scheme 5.1 or 7.1 , which will consist of a single speaker subwoofer and 5-7 satellites. As a result, you'll get the most out of the movies and you have the feeling that you are in a movie theater (unless, of course, and the picture is even better.)

Also pay attention to the material from which made ??the column. If they are made ??from cheap plastic, the sound of them will be poor. The best option would be a column of wood (MDF, particle board), just make sure that their structure is tight .

If you do not particularly need a good sound - speakers will be used only for signals of different programs, you can stop and on the cheap version.

How many columns are for the computer? unlikely that this question can give a definite answer, because depending on the quality, size and characteristics of the speakers their price will vary, where in some cases substantially.

Thus, the plastic tweeter speakers will cost you up to $ 10 , while the high quality speakers such as 2.0, 2.1, 5.1 and 7.1 will cost $ 30-150. But their price is fair, and in return for the money spent on them, you get high-quality sound, that will please your ears!

One should not buy a webcam with high resolution, when it is we do not need (to take a reserve). After all, in low light web camera with high resolution will shoot the video for order of magnitude worse than analog with a resolution of 640x480 (the higher the resolution - the higher the sensitivity to light).

A microphone in the webcam

For shooting video casts the figure should be higher, respectively.

Ergonomics and design of the web camera

Also, when choosing a web camera is worth considering the possibility of fixing it.

Solve Problems With The Printer

Solve Problems With The Printer

Solve problems with the printer itself

The printer is one of the most important complementary devices, especially in areas that are closely related to the documentation (offices, educational institutions).

And sometimes with printers , as well as computers with the very problems of various kinds, which are detrimental to the outcome. Typically, in each office or facility has a system administrator (sysadmin), which is engaged in setting up computer equipment and ensures that she was constantly running.

But what if problems arise with computers at home? - Of course, as an option, you can have a personal system administrator, or call it when needed for a fee. But you will agree that this option will be to take away from us, not only money, but also time. After all, we have to wait when it comes sysadmin and everything will work out.

But still, each user simply must solve issues related to the computer , the low and medium complexity - so it can not only save time and money, but will keep control of the situation in their own hands, that is much better than to depend on others people.

One common problem is not recognized by the computer (or laptop) printer connected to it - of course, that in this situation we can not print anything. What can we do to find out s the situation?

As with all of the problems related to computers, made in two parts: hardware and software, so needless and here. So let's look at each aspect in turn.

Hardware component

First of all, you need to check whether normally includes printers , does not issue whether it with some uncharacteristic sounds, etc.?

Next, verify that the power with which the printer is connected to a computer, is safe and has no mechanical damage.

Check also to see if everything is okay with the slots, which are inserted into the plug at the end of the cord (which may be different damage).

Software component

After checking the printer, cables, connectors, turn off the printer . Next, connect a special shielded cable (cable) computer and printer (printer is still off).

Next, insert a CD ( DVD ) ROM driver disk that came with your printer into the box , and then run it and follow the instructions.

If the drive does not, you can download the driver on the manufacturer's website (this pickup to these sites , choose the technique of "printers").

After installing the driver reboot.

Next, go to Start -> Devices and Printers , where you should have just installed the printer among other devices.

If not, then you need to remove the installed driver (so go to the Device Manager , where our printer with USB icon, then click on the right mouse button and the pop-up window, select Delete), and then restart your computer and re-install the driver .

At the second attempt must exactly turn out!

Why do I need a Uninterruptible Power Supply (UPS)?

Do I need a UPS?

Every computer owner, probably at least once in their lives with the problem stykalsya emergency shutdown to an unexpected power outage (such breaks often occur in small towns, especially during storms or high winds).

Me too, there was this kind of situation. When I was still at university, like all, he wrote a thesis on the 5th course. One evening, I was obsessed with this task, sat down for a whole night. We are almost in the morning thesis was almost ready. But then came the worst - was switched off (literally 10 minutes). Naturally computer blacked out, with none of the work I have done has been preserved.

I was just desperate. And I decided that the problem should be solved. And I solved it - went to the store and bought a UPS . After I finished the same thesis, which have "excellent."

Since then, UPS is a very important attribute of my PC. He not only to hedge against a power failure (usually after the loss of light may be another 20-25 minutes to work on the computer, then turn it in normal mode), but also protects your computer from surges in voltage, which often happens - and this is allow your iron friend live a much longer life than those without UPS.

The huge advantage of the UPS is also an opportunity for those who use the Internet via a telephone line, to insure against power surges in a telephone cable to connect it directly to the UPS. Thus you will allow your modem to last you as long as possible.

It should be noted that the cost of uninterruptible power supply is not that great. On average it is about $ 100. Although you can find cheaper options, and - within the 50-60 dollars. But it's not worth saving on this package to the PC, because the role and importance of it - just hard to overestimate.

If you still do not have an uninterruptible power supply , then it is mandatory to buy. If you are, of course, appreciate the safety of their work on the computer and want to use it as long as possible.
