DD- demand draft... its the word you'll get to heat in banks.... and DD is for the transfer of money to the others account....... for applying govt jobs / some other jobs, they ask you send DD of some amount and all........ i hope its correct...... thank you.......

The full form of DDR is Double Data Rate. It gives two data transfer per cycle,
the new version DDR2 which gives 4 data per cycle, ans latest DDR3 which gives 8 data per cycle. It has frequecy differece also. DDR3 has highest mbps
DDR3 can be used in latest motherbord because only latest motherboard that
is compatible with DDR3 , DDR2 can not be used in that motherboards.

Double Data Rate..it offers greater bandwidth,high speed,and lower power consumption..
Computer uses Memory installed on DIMM Slots on Motherboards.Nowadays different versions of DDR RAMs are used (DDR1, DDR2 & DDR3).Laptops use similar memories (DDR1, DDR2 & DDR3) but in small form of DIMM Sockets called Small Outline Dual Inline Memory Modules (SO-DIMM) memories.
ddr3
depending on the laptop, it could be DDR, DDR2 or DDR3. But the form factor is all the same. Its all SO-DIMM memory
It is a form, speed and type of memory.
DDR or DDR2
It depends on what you call a memory card. There are memory sticks (SDRAM, DDR, DDR2 DDR3) you can use to install and upgrade the memory. In the old days, memory came in the form of peripheral cards that you could use once you used up all the sockets on the motherboard. Little did most know that there was a simple motherboard modification that allowed you to use larger denominations of DRAM chips. Still, in those days, you could only have 640K.
There are a number of different names. They are usually in the form of SIMMs (Single Inline Memory Modules), and people often call them just memory modules. Some also call them memory cards or memory sticks. They may go by other names based on the exact chips and how they are wired, such as DDR, DDR2, DDR3, and so on.They are sometimes called MultiChip Modules. When their sole function is RAM they can be called Memory Modules.Sometimes they are identified by the type of connector: SIMM, DIMM, UDIMM, SODIMM, etc.Memory Modules (memory card)
The ATX form factor is an ancient one. Modules can range all the way from 72-pin DIMMS to DDR3.
Secondary memory (or secondary storage) is the slowest and cheapest form of memory. It cannot be processed directly by the CPU. It must first be copied into primary storage (also known as RAM ).

Rambus Dynamic Random Access Memory is the full form of RDRAM.
full form of SD-RAM is static disk random access memory..............................
