Also, could you please underline the answer?What is the process ID of the first process in a RedHat Enterprise Linux system that starts? What does this procedure go by? Also, could you kindly underline the answer?Give a programmer's perspective on why deep access is preferable to shallow access; don't focus just on performance.
- Explain in detail the fork and exec system calls with an example.Including the parent process, how many processes will execution of the following program result in? Assume that all fork() system calls succeed. #include <unistd.h> #include <stdio.h> int main(int argc, char **argv) { fork(); fork(); fork(); fork(); /* ... */ }If a command is not followed, what happens then? There are situations when a hardware-managed TLB might be slower than a software-managed one:
- Discuss 2 different approaches for detecting changes if the source application does not maintain an update timestampIf the program below calls fork() N (N > 0) times, how many processes will execution of the program result in (including the parent process)? Assume that all fork() system calls succeed. #include <unistd.h> #include <stdio.h> int main(int argc, char **argv) { fork(); fork(); fork(); fork(); /* ... */ }There are two options available for canceling processes and resolving deadlocks:
- Your company has grown significantly, and suddenly there is a significant increase in the usage of file servers. All of the file servers are in close proximity to the clients, and you're adding many more, resulting in a big group of servers. The number of namespace servers has also increased in recent years. Your original setup utilized the default options for the referral ordering mechanism and polling, which were both enabled. What modifications should you think about making?What's the main difference between a splitstream upgrade, a patch, a release, and a version in terms of system maintenance?In RedHat Enterprise Linux, what is the process ID of the first process that is launched? How would you describe this procedure? and if possible, please make the response stand out.
