Linux/Unix
Please describe the thread/process management with regards to the Linux/Unix system
Answer)
The threads are considered as the popular modern programming abstraction which helps in providing the multi-threads of the threads of execution within the same program in the shared memory address space can also share the open files as well as other resources
For Linux, it has the unique implementation of the threads where the threads are implemented as the standard process.
It is the Linux kernel which doesn't provide any of the special scheduling semantics or any of the data structures for representing the values/threads. It rather shares some of the resources with the other related processes where every thread would have the unique task_struct and also help in appearing to the kernel as a normal process

6. In POSIX systems (e.g., UNIX, Linux), we use system calls fork() and exec() for process management. Analyze the following programs using the data structures that OS kernels maintain to realize the concept of process. (a) Describe what you would observe and what would happen in the OS kernel if you run this program (the include lines are left out). int main() { fork(); printf("Hello, -CISC3320!\n"); fork(); printf("Hello,CISC3320!\n"); (b) Describe what you would observe and what would happen in the...
Scenario: Security and Memory Management Some have argued that Unix/Linux systems reuse a small number of security features in many contexts across the system, while windows systems provide a much larger number of more specifically targeted security features used in the appropriate contexts. This may be seen as a trade-off between simplicity verses lack of flexibility in the Unix/Linux approach against a better targeted but more complex and harder to correctly configure approach in Windows. question: Discuss the highlighted trade-off...
Unit 7 Discussion - UNIX / LINUX Operators 1212 unread replies.1616 replies. Topic: In Unix/Linux, Bash Shell operators are divided into various operational functions like defining, evaluating, arithmetic and relational, and redirection operations used by system administrators, for example, the ‘$’ (Dollar sign) in front of a variable is used to evaluate operators. Discuss the best operator for ‘defining’ operators and provide few working examples.

Using either a UNIX or a Linux system, write a C program that forks a child process that ultimately becomes a zombie process. Process states can be obtained from the command: ps -l The process states are shown below the S column; processes with a state of Z are zombies. The process identifier (pid) of the child process is listed in the PID column, and that of the parent is listed in the PPID column. Because you do not want...
