DMA allows a peripheral device to read from/write to memory without going through the CPU. DMA allows for faster processing since the processor can be working on something else while the peripheral can be populating memory.
DMA allows a peripheral device to read from/write to memory without going through the CPU. DMA allows for faster processing since the processor can be working on something else while the peripheral can be populating memory.
The advantage of DRAM is its structural simplicity: only one transistor and a capacitor are required per bit, compared to four or six transistors in SRAM. This allows DRAM to reach very high densities.
Advantages of DMA include: high transfer rates, fewer CPU cycles for each transfer.
Some disadvantages include: DMA transfer requires a DMA controller to carry out the operation, hence more expensive system; synchronization mechanisms must be provided in order to avid accessing non-updated information from RAM.
Does it helps you with your assignment? I hope so.. ^_^

It's faster. DDRAM stands for Double Data Rate Ram. The only one that is faster than DDRAM is RDRAM (Rambus Dram), but it is way more expensive and appears to be going off the scene.

Easy to access Doesnt take up computer memory
RAM or Random Access Memory is used for fast computer memory. The word "Random" is a bit of a misnomer, as there is nothing random about access to this memory. What it actually means is that you can select an address at "random", that is, any address within the capability of the memory, and read or write data to/from that address just as fast as you could read or write data to any other address. In other words, data stored anywhere in the memory can be accessed quickly. Serial memory is different in that access time depends upon where on the medium the data is stored. Examples are magnetic tape, optical disk, magnetic disk. "arbitary access" is not a term used in electronics that I can find. I think it is just another term for "random access".
random access memory
A desktop saves memory in the CPU. When one wants to access information, the random access memory, or RAM, is used. The amount of memory a computer has depends on the size of the CPU.
direct access allows you to access the needed record directly with serial access u have to go through all the others before arriving to the desired one
The advantage of contiguous memory allocation is 1. It supports fast sequential and direct access 2. It provides a good performance 3. the number of disk seek required is minimal The disadvantage of contiguous memory allocation is fragmentation.
list of typical direct memory channel
DMA, Direct Memory Access, is a method of transferring data from the computer's RAM to another part of the computer without processing it using the CPU.

The abbreviation UDMA stands for Ultra Direct Memory Access. The Ultra Direct Memory Access is a mass storage interface and is common in computers and other electronic devices.
