Part of the Diencephalon that secretes melatonin that helps regulate the circadian rhythm.

Part of the neuron that transmits the impulse to another cell.

Which of the following is considered the principal visual center of the brain?

The following are functions of the dendrites, except:

The following snippet of pseudo code for the producer consumer problem using semaphores has a logical error. Identify the location of the error, explain what can go wrong, and suggest a fix to eliminate the error. (Hint: you can assume that all down and up calls would be successful and not return an error code). semaphore m(1) // initialize counter to 1 semaphore s(0); // initialize counter to 0 Producer ============= sem_wait(&m) while (buffer full) {     sem_post(&m);     sem_wait(&s); }  // insert item into the buffer sem_post(&s); sem_post(&m);   Consumer ==============    sem_wait(&m); while (buffer empty) {      sem_post(&m);      sem_wait(&s); } // remove an item from the buffer sem_post(&s); sem_post(&m);

Write pseudocode that creates a child process, switches its standard output (1) and standard error (2), and lets the child process execute a program whose name is provided as a command line argument.  As an example, assume that helloworld binary’s main function is implemented as follows: int main(int argc, char **argv) {     write(1,”HELLO”,6);     write(2,”WORLD”,6);     return 0; } Let’s assume that the binary of the code you will implement is called changingWorlds would be called as  $ ./changingWorlds helloworld and after this the child process that will execute helloworld writes “HELLO” to file that was accessible through descriptor 2 in the parent process and writes “WORLD” to the file accessible through descriptor 1 in the parent process.
