Operating Systems

1. Managing Resources

   • Memory(RAM)
     • In order to ensure there is enough memory for each program that is running, Ram is split into “pages”
   • Processing/Multi Tasking
     • Multi-tasking is where a processor appears to be doing two tasks simultaneously
     • The processor runs commands from each task separately, filling in the time when it is waiting for other components.
   • Disk De-Fragmentation
     • Involves re-arranging file fragments on a physical disk surface to improve load times.
   • Backing Stores
     • Backing stores are storage devices used to keep backups of important files

2. File Compression

   • File compression is storing data in a way that keeps the same info but uses less disk space
