A MB of RAM is one Megabyte of Random Access Memory .Basically a computer only understands bits and bytes so a computer uses GB, MB, TB, and KB, as forms of measurements and it is associated with an amount of data.
There are 1024 MB in a gigabyte.
32mb sd ram or 64 mb sd ram
It is exactly what it is - 128 MB of RAM.
1gb ram
256 MB of RAM.
1280
256 MB of RAM.
It depends on what type of RAM
Actually it is quite the opposite. The more RAM you have the more speed at which data can be transferred to the RAM. An example is if you have 512 Mb of RAM then 512 Mb of data will be transferred to the RAM at a time, but if you upgrade it to 1 GB of RAM then 1 GB of data will be transferred to the RAM at a time verses the 512 Mb. So the speed at which the RAM stores data will increase if the size of the RAM is increased. I hope this answers your question.
64 MB of RAM is the lowest possible.
261500 KB = 255.3 MB = 1.9 GB
1GB = 1024 MB So, 32 MB is the difference
