My topic is MicrosoftThese are the three main things you need to do:First, you need to find references to answer these questions (1 source for each question) Marketing/ Sales describe how social media is being used? what technologies are being utilized? how business processes work ? how effective they are?Second, you give me the link of each source and also summarize each sourceThird, you answer one question in the paragraph, so it means you need to write four-paragraph to answer 4 questions.
