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.

∙ 11y agoThe 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.

∙ 9y agoAdvantages 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.. ^_^

Difference between direct and sequential access?
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".
What does ram mean in computer language?
random access memory
What part of the desktop computer saves 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.
Serial and direct access?
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
What are advantages and disadvantages of contiguous memory allocation?
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.

What does DMA stand for and what does it do?
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.
