Sccm2012r2 identifies the computers and user resources that can be managed using Configuration Manager. It can also find the network infrastructure in the environment. Discovery creates a discovery data record (DDR) for each detected object and stores this information in the Configuration Manager database. After a successful resource discovery, the information about the resource will be stored in a file, which is called the discovery data record (

ROM and RAM are both semiconductor Memory, ROM is short for Read Only Memory, and RAM is short for Random Access Memory. ROM can still maintain data when the system stops power supply, while RAM usually loses data after power loss. A typical RAM is the computer memory.RAM has two categories: Static RAM (Static RAM/SRAM). The speed of SRAM is very fast. It is the fastest storage device for reading and writing, but it is also very expensive, therefore, it can only be used in demanding scenarios, s

Http://bbs.xiyuit.com/thread-4143-1-1.htmlplease stay tuned for matching the CPU bandwidth and memory bandwidth! Don't let the memory slow down the CPU. Intel's CPU has certain requirements on memory bandwidth since P4. Why did Intel have to push Rambus to match P4? This is because both SDRAM and ddr ram are insufficient to meet P4's needs. For details, FSB is P4 of 533 (external frequency: 133), and the data bandwidth requirement is 4.3 Gb/s (Yes In

clock resources for FPGA internal logical resources IO Local clock network that provides high performance and low jitter clock resources for selectiio logical resources Bufgmux can be reused between two global clock resources. It can also be used as a normal bufg clock buffer. This buffer can only directly drive global clock cabling resources and only drive clock input; of course, the clock input of the FPGA internal logic trigger can also come from those common wiring resources, but those co

1. How environment variables participate in program operation(1) There are 2 environmental variables, one in Flash and the other in DDR. Uboot Read all environment variables from flash to DDR as initialization values for environment variables at boot time, and then use this part in DDR, the user can use the saveenv instruction to re-write environment variables in

module). Quite similar to Simms, unlike the two ends of the DIMM's Goldfinger, which are not interoperable like Simms, they transmit signals independently. Therefore, more data signal transmission needs can be satisfied. The same Dimm,sdram interface with the DDR memory interface is slightly different, SDRAMDIMM 168PinDIMM structure, the golden finger on each side of 84Pin, Gold finger has two card mouth, used to avoid inserting slots, errors will be

Its multiplication coefficient is 2. DDR2 s

1. Denx's uboot detection process for DDR memory From the above figure, you can see that there are 3 stages to be passed: (1) test data cable If the data cable is disconnected, then all tests are not discussed, so test data lines first. Data lines can have 2 types of errors: (1.1) Disconnect If it is a two data cable, simply write and read a pattern=0b01 (0b at the beginning of the binary number) to determine whether they are shorted or disconnected.

, so the CPU has become the core part of determining the computer performance. At present, the mainstream model has reached 3GHZ.Memory: Memory is also called internal memory or random memory (RAM), divided into DDR memory and SDRAM memory, (but SDRAM due to low capacity, slow storage speed, poor stability, has been DDR eliminated) memory is an electronic storage device, it is composed of circuit boards and

GDDR is the abbreviation for graphics Double Data rate, a kind of video memory, GDDR is designed for high-end graphics design of high-performance DDR memory specifications, which have exclusive operating frequency, clock frequency, voltage, so with the market standard DDR memory is different, is different from normal DDR memory and cannot be shared. In general, i
