yes, some ppl handle too many differnt things at work, those
super busy type, they tend to forget things easily, cos they dont
have enough RAM.
actually RAM is like short term memory. (Things like boss ask you
to finish a document by friday, but u forgot about it cos you have
too many other things in hand. Or maybe you have 7 girlfrens, you
tend to forget you promised to meet who on weekend.)
Hard disk space is like long term memory. (Things like you still
remember some of the maths formula you learnt in school, thngs like
your parents/close frens birthdate, the scene of your favourite
movies. )
How fast you can understand things or do some task is like the
speed of the CPU.
