A Fellow Student in One of Your Classes Struck Up

A fellow student in one of your classes struck up a conversation one day. "What's your major," he asked. "Accounting," you replied. "Wow I've heard accounting is a tough major. What accounting classes are you taking this term?" You started talking about your accounting information systems course, and your friend asked you the question(s) noted below. Prepare a written response for your friend.
-You tell your friend about some of the topics you'll be studying this term in AIS: information technology, financial statements, internal control, business documents and decision making. "Information technology" is mentioned specifically in the definition of an accounting information system presented in the text; information technology can also be used as a processing tool. Relate the remaining four items (financial statements, internal control, business documents and decision making) to the definition of AIS.
