Banker's Safety Algorithm in Operating System

When  a  new  process enters the system, it  must  declare  the  maximum number  of instances of each resource type  that  it may need. This  number  may not  exceed the total  number  of resources  in  the system.  When  a  user  requests a set of resources, the  system  must  determine  whether  the allocation of these resources will leave the system  in  a safe state.  If  it will,  the  resources are allocated; otherwise, the process  must  wait  until  some  other  process releases enough  resources.
