title: Difference Between a Direct-Mapped Cache and Fully Associative Cache
body: <p>I can't quite understand the main differences between the two caches and I was wondering if someone could help me out?</p>
  
  <p>I know that with a fully associative cache an address can be stored on any line in the tag array and a direct-mapped cache can have only one address on one line.</p>
  
  <p>But that's about all I know.</p>
