I have been told that if I increase my RAM (e.g.from 128 MB to 256 MB), this should not have any effect on the level of system resources. However, how does one explain the following: opening several browser windows, one after another, leads to a decrease (percentage) in system resources until eventually the level goes so low that the system does not respond! But, increased RAM is designed to facilitate the opening of several programs simultaneously. There seems to be a contradiction here. Can anyone explain? Thanks.
