Windows Vista will run on a computer with a minimum of 512 MB of RAM
RAM is the Random Access Memory. The most primary role of RAM is to copy the operating system in to itself and then load the Operating System so that you can work. Also when you install any software, it requires some minimum amount of memory, else it will deny to install.For DOS, 16 MB of RAM is sufficientFor Windows 98, Minimum RAM requirement is 32 MBFor Windows XP, Minimum RAM requirement is 64 MBFor Windows Vista, Minimum RAM requirement is 512 MB

If you're making the switch from 98 to Vista, you definitely want an entirely new machine. The requirements for Windows 98 were: * 66 MHz processor * 16 MB RAM * 500 MB hard drive space The requirements* for Windows Vista are: * 1 GHz processor * 512 MB RAM * 20 GB hard drive space * video card with 32 MB RAM on-board * Note that these "minimum requirements" will be barely able to run Vista. A system with a 3 GHz processor and at least 1 GB RAM are usually listed as minimum values by non-Microsoft parties. It is unlikely that the motherboard that came with your Windows 98 computer will be compatible with the minimum requirements for Windows Vista.
Officially, Windows Vista needs a minimum of 512 MB of RAM, and 1 GB or more is recommended. Unofficially, people have run Vista on as little as 192 MB of RAM, although this performed too poorly to be of any actual use.
