Hi,
Does anyone know which of these uses the most memory. Is it the cache?
Thankyou Tim that was a great answer.
So am i right in thinking my 16 Gb iPad has as follows:
16Gb of main memory (solid state). Containg music, video, etc?
256Mb system memory (is this equivalent to the RAM memoery in a PC?) For the cache
And 'X' amount of flash memoory for cookies and history?
PS
What size is the flash memory and is it RAM?
Just trying to learn.........
Thankyou again.
So if the cache is stored in the RAM memory. Is the cache cleared when you power off?
But it's not cleared if you just put it to sleep?
I'm wouldn't put any credence to what I say, it's bound to be wrong!
I understand what you mean about sometimes web pages not being stored in the cache. This morning I was typing a message into a website contact form, but halfway through had to check an address in the contacts book. When returning to the webpage, it had to reload and I'd lost what I'd typed.
Tim SPRACKLEN said:Safari's History and Bookmarks are stored in flash memory, while the cache is in system RAM. Because the iPad1 has relatively little system memory (256 MB) the cache can often 'overflow' the available system RAM - particularly (a) if you try to load multiple pages that are graphics intensive or (b) you switch to another app that requires system memory. As a result, when you return to a page that you've previously left, Safari may need to reload the original page - which can be annoying. I've read reports that this is now better on the iPad2 because it has 512 MB RAM. I find it annoying when you are, for example, typing iPad Forum posts into the iPad Forum website 'Message' box and need to swap to another page to get some information for your post. When you return, it may be the case that Safari has to reload the original iPad Forum page but, because the message text had not been saved but only cached, it is lost and you have to enter it again.
History, Bookmarks etc are stored in the iPad's Flash filing system and consume negligible Flash storage.
The ability to clear the cache and history in the iPad 'Settings' app is more for security - so that, if you've been doing some online banking and want to loan your iPad to a co-worker, you can clear all that personal information out of the iPad.
