This process is known as analyzing options. When Raul looks over different options and/or technologies that will help him do his job, he is going over the different options and seeing which option is best for him. When deciding which is best for him, he will need to consider: what Raul needs it to complete, how each technology option compares to the next, the price point and all of the functions the technology can do. After he figures out what it can do compared to what purpose he needs it to serve, he can determine the best option for himself.
You must spread your risks out like don’t put all your eggs in one basket... don’t rely on on thing because is it goes downhill you have no backup
Let's assume a condition where ram is 256 MB and the program size is more than 256 MB
in that case, CPU has to wait for I/O to load the remaining part of the program..in this case
CPU utilization is much poorer.
So adding gives benefit only when your CPU is fast enough to take advantage like if a process waiting for I/O
it can put the current process in the run queue and take another process from the ready queue.
This way a better CPU utilization can be achieved.
So by adding ram we can load more programs while waiting for I/O . CPU utilisation will be better.
here by adding 2GB ram we can load 2048/256 = 8 new process into ram at the same time.
2. if cpu have to execute the cpu bound process that wait for I/O cpu will be idle most of the time while
waiting for I/O to be done..this way CPU utilization will be poorer as compare to earlier.
