Data Memory

Both server memory and normal PC memory are memory (RAM), and there is no obvious difference in appearance and structure, but the price is higher than normal memory. Server memory is also memory, it and we usually see in the computer city in the ordinary PC there is no obvious difference in appearance and structure, it is mainly in the memory of the introduction of some new technology, ordinary PC memory on the server is generally unavailable server can not recognize, This means that the server memory can not be arbitrarily for cheap with ordinary PC memory to replace the reason. Some people put some kind of technology inside ...

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

The development of the computer today, all kinds of hardware products of the homogeneity of the phenomenon more and more serious, not only include the product of the work of materials, and even product packaging can fully achieve the "You have me I have you" realm. Take the video card radiator, highlighting their non-public version of the characteristics of the manufacturers have been playing the acme of excellence, different shapes of the graphics card radiator in succession. All kinds of strange graphics card radiator appearance also verified that the phrase "only can not think of do not" myth! But deep down, the graphics radiator will be less attractive to consumers. 　　Cottage better? ...

With the development of the Times, computer memory more and more, from the original 1M, 2M, 4M and other development to the present 128M, 256M, 512M, or even greater. Therefore, the rational allocation and use of memory is very important to avoid unnecessary waste. Moreover, memory and general external storage devices, such as the disk commonly used (including hard disk, CD-ROM, etc.), have many advantages, such as the speed of memory is very fast, usually dozens of times times faster than the latter; the capacity of the disk is limited, especially the floppy disk, The size of a floppy disk is generally 1.44M, so the startup disk often ...

I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address. What is the use of virtual address? Virtual address is how to translate into physical memory address? This chapter will give a brief account of this. 1.1 Linux Memory Addressing Overview Modern operating systems are in 32-bit protected mode. Each process can generally address 4G of physical space. But our physical memory is generally hundreds of M, the process can get 4 ...

Absrtact: With the rapid popularization of mobile phone, digital camera, tablet computer and vehicle navigation equipment, users ' demand for high speed and large capacity memory card is more and more, and Toshiba company, as the founder of Flash World, has been leading the development of storage industry. With the rapid popularization of mobile phones, digital cameras, tablet computers and vehicle navigation devices, the demand for high speed and high-capacity memory cards is increasing, and Toshiba, the creator of Flash memory, has been leading the development of storage industry.

It's written in the front. With regard to the practical guide to interactive design, we have recently received feedback from many friends, supported and criticized, and thanks for your attention, we can go further. "Interactive Design Practical Guide" is actually collecting and summarizing some of the problems of interactive design, there must be a lot of old things, is not a cliché is not a problem, "the problem is that these old things have not been accumulated, has not been inherited, has not been structured." "(Qingyun) the interactive Design Practical Guide has a readership that covers many industries, and even interactions ...

Oracle is planning to release a series of memory-based applications that will keep Oracle in the forefront of competition with SAP. Oracle announced in Tuesday that it will launch more than 10 memory applications, and its spokesman said the first three will be launched in May, including JD Edwards EnterpriseOne as Sales Advisor JD Edwards EnterpriseOne Memory Sales Advisor), JD Edwards enterpriseone in-me ...

"Three times a year upgrade memory, still can not meet the high requirements of antivirus software." Each upgrade product model, the computer's system resource occupancy rate is soaring, anxious to maintain the highest configuration of the year to become! Now, at the same time get efficient security and smooth network operation, unexpectedly became a kind of extravagant hope! "Mr. Zhang, the IT director of an enterprise, and many of the enterprise's IT executives, is hard to choose between efficient anti-virus products and optimizing network resources." Based on the customer's dual demand for security effects and minimum hardware configuration, trend technology pioneered cloud security technology in July this year, surpassing traditional code ...

Absrtact: In 1971, physicist Leon Chua proposed the concept of a fourth integrated circuit basic component element. He believed that, due to the symmetry, the new components would be created and added to the existing three kinds of element resistors, capacitors and sensors. When 1971, physicist Leon Chua presented the concept of a fourth integrated circuit basic component element. He believes that because of symmetry, new components will be created and added to the existing three constituent elements-resistors, capacitors and sensors. At that time, he for this ...
