No. All RAM has to run at the same speed. The USB bus is much slower than the memory bus inside.
Virtual memory is a way of allocated extra space from your hard drive as RAM space. For instance, if you are running a program which is memory intensive such as Photoshop and you don't have enough RAM to handle all the temporary memory requirements, but you have a few extra gigs of space on your hard drive, you can set your Virtual Memory to 2 or 3 GB's to help balance the load.
The instructions for the addition of extra memory to a Mac will depend upon the particular model of Mac. Most will have a flap that opens so that a memory module can be pushed into place. (See links below for example)
If you are running Windows 7, then Microsoft offers a free antivirus program that is probably the best you can get. If you are running an earlier Windows system, then AVG is your best best. If you are running a Mac or Linux laptop, then no antivirus software is needed. dorothy.wilson8081@yahoo.com
memory card what kinda memory card where can I puchas one
No.
Brunel designed it to be 7 ft exactly, but possible problems with friction on curves meant an extra ¼ inch was added to allow for smoother running.
Yes you can.
Usually, just one, but I don't think you should have more than one. I think it is possible to have Windows and Linux on one hard drive. well it also depends if you want to have more the 1 partition. The way to do that is to format the disk or at the start of installation process you change the amount of memory you want in your C drive and with the extra memory the can make a new partition. But if you have to many partitions you can really mess up how your computer boots up.
You can expect to pay about $15 for an extra 8 GB micro SD memory card.
The memory of music.
yes
Either buy a new harddrive or buy a memory card.
