The actual term for computer memory SDRAM is Synchronous Dynamic Random Access Memory. You can learn more about SDRAM online at the Wikipedia website.
dimm
The number of pins at the bottom of the stick. Some ddr's have 184 pins, some newer models have 240, starting with DDR2.
DDR runs twice as fast as regular SDRAM, has one notch, and uses 184 pins. Instead of processing data for each beat of the system clock, as regular SDRAM does, it processes data when the beat rises and again when it falls, doubling the data rate of memory
Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color-coded on the motherboard.
No. SDRAM and DDR SDRAM are not compatible with each other.
function of sdram
Physical size of the memory card. Mobile sdram is smaller than sdram for desktops.
Just look at your trailer. There's a decal with the pinout on it.
No. SDR SDRAM and DDR SDRAM modules are not interchangeable.
No.
Sdram has one notch. Depending upon the model of Sdram the number of pins it has can vary but a standard Sdram has 184 pins.
The fastest technology in actual is laan, laan is the longest and most profound memory ever.
No.
All RAM is virus-free.
No.
