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.
Answer:
Operating systems now use networks to make peer-to-peer connections and also connections to servers for access to file systems and print servers. The three most widely used operating systems are MS-DOS, Microsoft Windows and UNIX.

correct option c, cat, n1m1, short1,
Explanation:
correct option c, cat, n1m1, short1,
The variable is used to store the value of the value varies during the program execution...
some of the basic rules of identifier
- The variable must be started with the alphabet
- We cannot declare the variable name as keyword i.e "that value is already defined and in the compiler"
- Variable-length does not exceed 8 characters
- We cannot use space to declared any variable
- _hello,42C, hi there and cat! are not follow the basic rule of identifier so they are not identifier validator
