[bcab] Re: Available memory.

Thank you Gulp! trying to understand. I asked as when I had Lunar put on my computer to enable JFW to work in Monochrome because Lunar will invert the screen. Tony a Rnib Volunteer, now recently gone to live in France said Lunar seems to use a lot of Ram, so I increased from 512 to 1 MBor Meg. Tony also said Messenger gobbles memory and Windows Messenger don't bother with them. Recently when I upgrade to the latest Version of Kurzweil. I listened to the tape instructions and realised these voices will need a good bit of memory. They are Powerful. Jaws also has some powerful voices now. I think Tony said Kurzweil your OCr will not use available Ram, I don't understand as I am moving in and out of both Jaws and Kurzweil frequently but are both using Available Ram or not? Sorry to be so dense. However how can I tell by looking at my computer the amount of Available Ram I am using and the memory I have left. I do not store music files and am using my computer simply have a good few Photos people have sent me not that I can see them well but I like to have them Do they take up memory or just Hardrive space.

I'll have a go. The processor works with memory, also known as RAM or
random-access memory. Memory comes on chips and is installed in the
computer. It is mesaured in bytes, kilobytes, megabytes and even gigabytes. 
When you switch off the computer the memory looses its information.
Hard drives are storage devices. The processor cannot work directly with the 
hard drive, it can only execute instructions in memory, so programmes and
data get loaded from the hard drive in order to be processed. Besides, RAM
is much quicker than drives. Thus, you need an amount of physical memory in 
your computer for it to function. If you don't have enough RAM you will
either find that some aspects of programmes won't work at all or that the
computer slows down significantly because it is using space on the hard
drive to swap memory back and forward.

The main confusion comes about because hard drives are also measured in
megabytes, gigabytes and even terabytes.

Cheers,
Steve

Can anyone explain about  Available memory  for example  some of the new
voices are quite powerful and I imagine in both JFW and Kurzweil would need plenty of what you call Ram, I have never really understood how to find out 
the difference between available and other. does available mean left over?
If so how do do I find out what is left.

I seem to recall something about Available being different however, would
Jaws 8 and K11 be using 'available Ram' and if one is and other not can you explain just what is using what.sorry the question is not set out 
well, it was just that  these new powerful voices must use more of
something? Dorothy
