Actually I don't think that's the best analogy given the differences in the memory architecture. Computers use volatile random access memory. Turn the power off and everything that wasn't saved to your hard drive goes bye bye. BB's use flash memory. Turn off the power or do a battery pull and everything is there when the power returns. PDA's like older Palms, Visors, Clie's etc. have volatile memory as well.
What's really happening with memory leaks results from using flash memory. On a computer, memory is used and freed dynamically. Thus when you start MS word and write a letter, the program grabs available memory to run and then releases it when you close the program. The PC OS and hardware is such that this can happen so fast that even if you didn't reboot your PC for a long time and your RAM got very fragmented, you wouldn't lose any available memory and wouldn't notice any performance degradation.
Note this applies only to real RAM, and not virtual memory which pages data to a hard drive. You get huge performance loss (I speak from experience) on older PC's with a small amount of RAM that requires lots of virtual memory paging.
When you do a battery pull on your BB, the OS and apps are loaded in sequence which maximizes your free memory. As you add data (emails, texts, browser data), run apps, and generally use your BB, bits and eventually chuncks of free memory get lost resulting in lower file free memory. The problem is exacerbated by poorly designed apps that probably don't properly allocate and release memory. When file free drops down around the magical 12MB, your BB starts to get sluggish, because the OS is constantly swapping in and out of a small amount of memory. Time for a battery pull.
12MB is the general limit where performance drops and data such as emails and texts automatically get deleted.
To the OP, the real reason you don't a memory leak is you get 1's and 0's all over the place.

I think I recognize the user name. I have had the MemoryUp Pro since I first got my Curve and it is a sweet program, I use it all the time.
Glad to see that you made it over here
This is where the action really is
~Jazzi~
PM me if ya still don't know who I am
Yep, definitely know you. Glad to see people I know here.
I'm itching to wait for my t-mobile contract to end so I can upgrade this summer. New BB means more memory, functionality and addiction levels.02-26-09 04:06 PM - lol.. thanks for the technical explanation. i will refer back to it if i ever see questions similar to the one in this thread.Technical Answer Alert
