In a paragraph, comment about how logging into the library system while in the library (Part a) is different from logging on remotely. (Hint: Consider different aspects of security as well as users who would like to use a browser other than the one used in the library.) c.

The form should ask for name, date and time of visit, general purpose for computer use (i.e., word processing, Web surfing, examining real estate documents on line), and the time they have logged off. Label the seven sections of a form that you included.
