Just because your laptop is sluggish doesn’t always mean it must be replaced. Your office desktop may slow down just because you looked up the weather report while editing a PDF.
When a computer needs space to ‘spread out’ and work, it requires memory – or RAM – to process your requests. With so many applications requesting memory, your computer sometimes compensates for a memory shortage by using disk space — which works much slower than RAM.
Sometimes we confuse the two – memory and disk space. One has nothing to do with the other – except when memory runs low and disk space is used as a slow substitute.
