The fast results of SQL queries is a result of b-tree indexes used by a SQL Server. A single B-tree consists of number of index nodes, root nodes, branch nodes, and leaf nodes that enable you to systematically store your data. Corruption in any of the nodes (specially index nodes) can result into inaccessibility of records stored in the database. In most of these situations, you encounter an error message stating the exact cause. To surpass the above database inaccessibility circumstances, you will need to use restore the data stored from an updated backup. However, in absence of an updated backup or backup falls short to restore the required data, then you will need to search for advanced third-party sql repair application.

B-tree chain linkage mismatch. P_ID1->next = P_ID2, but P_ID2->Prev =P_ID...

If you do not have a computer at home, you are most likely still living in the ice ages! Since the information age, the amount of information that the average person has to process has increased tremendously. Right now, if you go to an office, I believe that it would be impossible not to see any computers. Previously computers were confined as mainframes or super computers which were hugh and required loads of space to fit and tons of electricity to operate. Due to the improvements in technology, the computers shrunk and could be compressed into the size of a desk top. Now things have gone even a step further as computers now are only the size of palm tops or what they all call it net books. Then there was the invention of the internet which greatly expanded the influence of computers. Originally intended to be an internal network or intranet, the internet eventually became something that expanded throughout the whole world. In my opinion, the creation of the internet further spurred g...

The invention and the history of the Dell computer is quite interesting. First of all, it was in 1984 when Michael Dell, a student at the University of Texas at Austin, created the company PC's Limited. He only had a starting capital of $1,000. So what he did was he started working out of his dorm room to build personal computers made from stock components. These computers were to be IBM compatible because that was the standard at that time. If a computer were to function with various pieces of hardware, it needed to be IMB compatible since hardware and software programs were being designed to be IBM compatible. It is when Michael Dell figured that selling computers directly to customers to determine customer need that he dropped out of college. His family then extended him the $300,000 in expansion capital that he needed to make his business take off. A success It was in 1985 that the Turbo PC was developed and it sold for less than $800. It contained an Intel 8088 processor that ...

Many employers would like to know what activities are going on with their employees on the office computer, when they are not being supervised. In other situations a wife may suspect a husband of cheating with someone they speak to online or their children may be speaking to an adult that could lure them into giving them valuable information or that could hurt them or worse.

For quite some time now, computer systems have been used to aid the learning process of students in the United States. From primary all the way to the university level, computers have become an integral part of the educational process itself. In a way, the American educational system has indeed progressed in leaps and bounds. It has moved away significantly from the 18th century model of public education that had begun in Western Europe just a few centuries before the birth of the Internet. The use of computers has also spawned a collaborative and yet competitive environment for learning. The competitive nature stems for the actual competition among students for higher marks and better learning results. According to David Williamson Shaffer, a researcher and critic for the Journal of Interactive Learning Research: "Interviews with students suggest that the processes of collaborative learning in this competitive environment were fundamentally similar to collaborative learning proce...

A new computer in pristine condition, right from the box, will run at the full speed it was built for. Exactly how fast it runs depends on the speed of the computer chip,the amount of software you have installed and the amount of ram memory you have amongst other things.Obviously it also depends on the type of internet service you have. A dial up service is slow no matter what kind of computer you have. A broadband high speed internet service is fast and some extreme high speed services are available which are even faster.

"Lapping" a CPU involves removing the IHS (integrated heat sink) from the processor. Due to manufacturing variations, the IHS on processors may be slightly concave or convex. This results in an uneven contact with the heat sink which degrades cooling by a moderate margin. If you're an enthusiast who loves to overclock, lapping your processor is a very good idea. Not only is it the cheapest cooling upgrade you can perform, it is also the most beneficial when looking at the price/performance ratio. The extra cooling may even allow you to overclock your processor further because of the increased cooling. In this guide, I lapped an Intel Q6600 G0. Before lapping, I was only able to overclock the processor to 3.2Ghz maximum temperature under load was 70°C for Core 0 and 69°C for Core 1. Ideally, you want to keep the CPU temperature below 70°C. After lapping, the maximum temperature under load dropped to 62°C for Core 0 and 57°C for Core 1, a maximum decrease of 12°C - quite a ...
