HW01 After carefully searching the internet and your notes for lectures, come up with your own TWITTER DEFINITION (No More Than 140 Characters, including punctuation and spaces) of an OPERATING SYSTEM. Use only abbreviations that are standard, like OS for Operating System or I/O for input and output (if you need them). After the definition, put your sources. Remember, this must be IN YOUR OWN WORDS and you should always include your name and course number at the top of the papers you turn in, even if you are sending them as email attachments.
