Coming to the audience, Tim cook did not make people wait long for traditional numbers. He invited Craig Federighi, his colleague, who told the audience about OS. After that, the attention of the audience was focused on the most advanced mobile operating system (OS) — iOS. And finally, what everyone was looking forward to: iOS 8, the latest generation of the system, was introduced. Once again, the new iOS turned out to be much better than anything we had seen before. No wonder Apple has spent a whole year on its development. All expectations were fully met.

The device of the computer. What a computer consists of

Nowadays it is impossible to imagine your life without a personal computer. He's got every corner of our existence. Up to the fact that some users spend days behind it. Five years ago, and it was impossible to think what opportunities will bring into our everyday life a personal computer. Now you do not need to go to the Bank to make any payment. I think it's going to get to the point where you don't have to go to the store. All will be ordered via the Internet. I think that against this background, each user needs to know the device of his computer, so in this article I will tell you what it consists of. I will not go too deep, for an ordinary user will know the basic device. More in-depth study requires separate large articles. If you still do not know anything and do not represent what components is your PC, then this article is for you, and then for themselves decide whether you need a deeper knowledge of his device or will manage what you learn from this article. So, the first thing to say about the device of a personal computer (I think it's so everyone knows, but for the completeness of the article still need to talk about it). The first is the system unit The device of the computer. System unit And the first mistake of an inexperienced user is that it is called "Processor" (why, I don't know). Processor R12; this is quite another, and after reading the article to the end you will understand that the system unit is not a processor. Second, this monitor The device of the computer. Monitor What is the monitor, I think no need to explain it so everyone knows. Third, this mouse The device of the computer. Mouse With it, almost all the manipulations in the operating system are performed. To it even suited expression of R12; Without mouse as without hands. If anyone else does not know (which I doubt very much) mice are of two types R12; wired and wireless. Both types of mice have their advantages and disadvantages. The advantage of wireless mice is that they don't have a wire, but the disadvantage is that you often have to change the batteries very often (depending on their quality). In wired mice everything is exactly the opposite. Fourth, this is the keyboard The device of the computer. Keyboard With the keyboard everything is exactly the same as with the mouse, we can say they are inseparable friends and very well complement each other. So, these were the main components of a personal computer without which work on it would not be possible. There are also additional components, such as printers, scanners, Webcams and other pribludy which in principle are not so important for the functioning of the PC and are installed as needed. Now consider the system unit device. The basic element of the computer. To find out what is the system unit, you need to look inside him, which is often afraid to do inexperienced users. Main parts of the system unit The first thing we see by opening the side cover of the PC is the motherboard The device of the computer. Motherboard Main parts of motherboard: 1. The connector where the processor is installed with a cooler. 2. Video card slot. 3. Memory slot. 4. SATA connectors for connecting a hard drive or DVD ROM. 5. Connector for the power supply. Second, it is the side of power. Here so it approximately looks The device of the computer. Power supply It is responsible for powering all devices in the computer system unit. Third, it's a video card. Here so it approximately looks The device of the computer. Video card so look more modern video card The device of the computer. Video card The video card is responsible for displaying the image on the monitor. The more powerful your graphics card is, the faster your video performance will be, especially for computer games. Fourth, it is a hard drive The device of the computer. Hard drive The hard drive is responsible for storing information. It's kind of a stock your photos, movies, music, etc., etc.. In General, all that you have on your computer, all this is stored on your hard drive. (That was really quite clear, I will give an analogy R12; principle hard disk as for example video cassettes, recorded him something, so there it will remain until sterate) Well, the fifth is DVD-ROM The device of the computer. DVD-ROM I think there is nothing to explain. Everyone knows what a DVD-ROM is and what it is for. But so looks the system unit Assembly. 1. Here is the power supply. 2. Here is a cooler that cools the processor. Actually under it also the processor is located. 3. This is a video card 4 and 5. Here is the hard drive 6. There is usually a DVD-ROM The device of the computer. System Part Here in principle also is the main device of the personal computer which in my opinion each not moved user has to know. At least in order to have at least some idea of what he is working on.

Learning to clean your computer from dust

In this article I will tell you how to clean the computer from dust. Many do not even think that sometimes you need to do cleaning your PC. Do you know what a vacuum cleaner is and what it is for? Right, to remove dust. That's the system unit of the computer also works as a vacuum cleaner. After all, it has coolers (cooling fans, only small), which are constantly working and draw in the air in a place with dust, which settles inside the system unit. Imagine, it has 3-4 coolers and how much they will pump into the computer for months or even years of operation. As you know, the dust is a conductive material and if a very long time not to clean, the computer can simply fail, even if it is due to the banal overheating. A repair will cost you a lot of money. You do not need to specifically apply to any special services, where you have to pay incredible money. You can clean the dust from the system unit yourself. Especially because there is nothing complicated. So, what we need for this simple procedure. 1. A cross screwdriver (possibly flat) to remove the side cover of the system unit. 2. Soft brush. 3. Cotton swab 4. Hoover. That's it! The first thing we do is Unscrew the two bolts on the back panel and pulling on (as if pushing it) remove the unscrewed cover . How to clean your computer from dust Smor inside the system unit and " Oh..AEM " (sorry for expression) from two centimeter layer of dust. I haven't looked inside for three months, and this is what's inside me. How to clean your computer from dust If you have not opened the system unit for a couple of three years, you may see this picture. How to clean your computer from dust But it's okay, if the computer has not broken down you have time. In this situation, take a vacuum cleaner and not touching any parts clean the main layer of dust. Next, we produce a more thorough cleaning. Namely, those places where the largest accumulations of dust. This is the processor radiator, all coolers, hard drive locations, power supply, but the most basic is the processor radiator, which is located under the cooler. How to clean your computer from dust Next, take a cotton swab and as if we clean the dust from under the cooler (do not be afraid to shuffle the stick on the radiator, it is iron, nothing will happen to it). You can keep the hose close to the included vacuum cleaner. to immediately sucked up all the dust. It is not necessary to lick everything to Shine, remove the main layer, this is enough But it's okay if someone That's how I got from one of the CPU heatsink. In principle, this is the main place of accumulation and the most important part, because it cools the brain of the computer R12; processor, and without air cooling stops and it can simply burn from overheating. But it's okay if someone Next, clean all other surfaces. To do this, take what some soft brush. For example here such (I stole it out of my sister's handbag), But it's okay if someone and looked like dust from all surfaces, as with iron, and with the motherboard, graphics card, hard drives, chips, and generally everywhere where you can climb, thus keeping hose included cleaner next to captured up in the air dust. But it's okay if someone Once again, no need to clean everything to Shine, just remove the main layer. Pile up you can still clean the power supply. This is also very simple. At the back cover, unscrewed the four bolt and block pulled out freely (of course the system blocks are different and maybe just so he won't come out), depending on the model of the power supply, spin it on the bolt and removed the cover. Look inside, also take a vacuum cleaner with a brush and remove all the dust. In General, from my own experience, I would recommend to clean your home computer about once every three or four months (well, if you do not want to, at least once in half a year). And due to such maintenance, the service life of the system unit will be much longer.

Does the laptop stand help?

In short: the stand for a laptop does not save the laptop from overheating, but rather helps the laptop to die faster. Detailed: If the laptop is new, it is not heated. But after two or three years(who has earlier, who has later), overheating of the laptop is already a problem. When the laptop overheats, it slows down, buggy and can even permanently break. In this case, you need to carry a laptop specialist for cleaning, replacing the thermal paste on the processor and thermal rubbers on chipsets. After cleaning, the laptop works well again. But many owners are too lazy to give the laptop to be cleaned(don't know what it should; no time; don't see the point) and they'll buy a cooling stand, considering something like this: "Here is my laptop really hot, and buy me under his special stand, the stand has fans, and they blow on the body of the laptop and the laptop will be cool." That's what I thought one of my old client-the happy owner of a laptop Hewlett Packard Pavilion dv5 (about my attitude to the company HP can be read here). And, I must say, by the time the 5-year - old laptop literally basked like a stove-hostess in the winter at work on his hands warmed. She bought a stand for a laptop, like a laptop has ceased to be so hot, but still worked bad. In the end, still gave the laptop to me to understand. I turned on the laptop and looked at the temperature of its CPU through Aida64. Just started the processor T5900 had a temperature of 65 * C. Wow! Such a temperature it should have except for a long load.   Speaking of load, I ran a stress test in the same Aida64 and the CPU temperature quickly went up. When a couple of minutes later the temperature of the processor exceeded 90*, I turned off the laptop away from sin. Everything is clear-the laptop is experiencing a wild overheating of the processor and chipsets.   After cleaning and replacing the thermal interfaces, the temperature of the just started processor became 35 * C, and after a few hours of stress test-65*C. in this mode, the laptop stopped braking and overheating without any supports.   While cleaning the laptop was slow and buggy even with the stand. But why, after all, stand fans improve cooling of the notebook? The fact is that the stand for a laptop is not cooling the processor and chipsets of the laptop, but only the laptop case. CPU overheating is equally regardless of the ratio of the under body or not. Why is a laptop stand-evil With normal heat exchange, heat from the processor and chipsets is removed from the laptop through a metal radiator and fan.   When the laptop is clogged with dust, and thermal paste on the processor dries up, the correct way of heat removal is blocked and the excess heat is removed incorrectly: through the system Board and plastic of the case. That is, the processor heats up and heats up the system Board, which in turn transmits heat to the laptop case.   Hence, there are two unpleasant moment: 1. The CPU is cooled poorly and is located in an extremely heated state. This leads to brakes and glitches at work. The processor may be stupid to burn out. 2. The system Board is overheating. This leads to micro cracks in it and the breakdown of the chipsets (the"pile bridge"), then the laptop stops working. This is where we go back to the treachery of the stand. Seeing that the laptop is very warm, the user buys a special stand for it, which really cools the laptop case. Body, body only! The user calms down and rapes the laptop further. But overheating of the processor and incorrect heat exchange through the system Board has not gone away, and therefore sooner or later "fall off" chipsets or "burn" percent. And in both cases, the laptop stops working and repair it will be expensive. Conclusion The laptop stand does not help cooling the processor and chipsets of the laptop, because it does not eliminate the causes of heat exchange. The stand for a laptop contributes to the damage of the laptop, because it gives the owner of the laptop false illusion of security and the owner may not have time to give your laptop to clean. Every 2-3 years, the laptop should be given to clean the dust, replace the thermal paste on the processor and thermal rubber on chipsets.

Master data management best practices

According to Experian research, which involved 1,400 organizations from eight countries, companies are increasingly aware of the economic potential of information: 79% of respondents believe that by the end of the decade, customer data will determine most sales decisions. However, almost all respondents - 90% - still believe that they lack a constructive approach to effective data management.

On average, almost 25% of customer data contain inaccuracies. Among the most common errors:

incomplete or missing data outdated information duplication of data conflicting information According to research by Experian, the company believes that could increase sales by nearly 29% in the presence of accurate client data.

It is estimated that in 2012, an impressive amount of data – 5.5 quintillion bytes-was generated each day, at a time when mobile communications were estimated to reach 61% of the world's population. If we assume that by 2017 this figure will increase to 70%, it becomes obvious that the volume of data in the coming years will grow exponentially.
