Consider the interaction between a student and a professor during an office hour session, in which the professor waits for a question from a student and then answers it, while the student waits for the professor, asks a question, and then waits for the answer. Once answered, the student asks another question... and the interaction continues in the same way. Write the code for the student and professor processes to synchronize their interaction during this office hour according to the scheme described above. Your code must use the necessary number of semaphores, where all semaphores are initialized to 0; make sure you use the wait() and signal() operations. Name your semaphores according to what they are guarding. Your code does not need to follow a particular programming language: Use pseudocode instead, like we did in class.

Malware, not sure what else would fit that description.

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.
