Hi pupil here's your answer ::
________________________
RAM ::
● Data can be read and written on the RAM chip at any number of times.
● The operating system, application programs and the user data is stored in Ram only until the computer is powered on.
● Ram is a volatile memory that loses its contents when the computer is switched off.
● The size of RAM makes a difference in the processing, i.e. the bigger size of the RAM the greater is the speed of processing.
ROM ::
● Data can only be read from the ROM chip.
● Only system programs are stored in ROM. It can't be used to store user data and other programs.
● ROM is non volatile memory the data stored in ROM is permanent in nature.
● Size of the ROM has nothing to do with processing.

Answer and explanation :
the three control problems associated with competing process are
- MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
- DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
- STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing then low priorities process have to wait for very long time this is called starvation
