What is DDR, SDRAM, SSD, HDD, DRAM, DDR2, DDR3, DDR4 ?
Ans. The post what is DDR, SDRAM, SSD, HDD, DRAM, DDR2, DDR3, DDR4, DDR5 for its description. Also this post is for best information. So, read under description about DDR, SDRAM, SSD, HDD, DRAM, DDR2, DDR3, DDR4, DDR5.
DDR | Double Date Rate | For Data Transfer |
DRAM | Dynamic Random Access Memory | Dynamic |
SDRAM | Synchronous Dynamic Random Access Memory | RAM Access Dynamic System |
HDD | Hard Disk Drive | Computer Drive |
SSD | Solid State Drive | Special Type Hard Disk |
Data Transfer Rate Chart :
RAM Type | Introduced year | Associated (RAM) Clock Rates | Approximate Transfer Rates | Word Per Clock Cycle for Date Transferring Amount | Voltage for Operate |
SDRAM | 1993 |
| 100 to 166 (MT/S) | 1 | 3.3 Volt |
DDR SDRAM | 2000 | 100 to 200 Mega Hartz | 200 to 400 (MT/S) | 2 | 2.6 Volt and 2.5 Volt |
DDR2 SDRAM | 2003 | 200 to 400 Mega Hartz | 400 to 1066 (MT/S) | 4 | 1.8 & 1.55 Volt |
DDR3 | 2007 | 400 to 1066 MHz | 800 – 2133 MT/S | 8 | 1.5 Volt, 1.35 Volt |
DDR4 | 2014 | 1066 – 1600 (MHz) | 1600 – 3200 MT (Per Second) | 8 | 1.2 Volt |
These systems actually for motherboards are built to support only one type of memory. You cannot use the same type motherboard without combo mother board. The DDR, SDRAM, SSD, HDD, DRAM, DDR2, DDR3, DDR4 motherboard not mixable. And they will not even fit in the same sockets, and function. It is represent further improvements in memory function technology.
If any person cannot identify the exact model of computer he can use System Scanner Tool. He can get his computer hardware information automatically and its system information.
Conclusion: I hope the simple post will be helpful in short word for full information. It has short description but it is enough for brought description for you. So, thanks a lot for read this content.
