2.5GB is a likely measurement of RAM or memory for a modern computer. A hard drive or you C drive is different than your Ram and can be 400GB for example. In that case your computer can store 400GB but can only work with 2.5GB at a time. It uses processor and bus speeds eg 2Ghz to quantify how fast it can take data out of storage and into memory and viceversa. RAM may also have i/o speed limitations which would probably also be measured in Ghz or Mhz but the standard way to characterize RAM is by its size in GB (GigaBytes).
Megahertz or MHz is not a measurement of the amount of ram. Ram is usually measured in megabytes or more likely gigabytes. Although, the frequency that the ram operates at is measured in megahertz. For example a stick of ddr3 ram can have 2 gigabytes capacity and operate at 1333 megahertz
Most likely the metric system of measurement is used. I would assume millimetres would be the most likely measurement between letters.
RAM's are rated in a measurement of bits. Depending on how much RAM your computer uses the RAM can be rated in either Megabits or Gigabytes.
Meter.... or more likely millimeters
liquids= ml. solids= mg.
Not likely. It would mainly cause a poor running engine.
What are the likely maximum and minimum values for this measurement 20.4+_0.1cm
It would most likely not be in the base model.
feet or meters
Centimeters or millimeters.
The type of RAM that is used in laptops would be the smallest RAM which would be SD-RAM.
Most likely you are timing out from a lack of Ram or Faulty ram. Or perhaps a poor internet connection. However it is more likely that a ram stick is the solution to your problem.
