How can a company raise funds to finance their operations and projects?

Mundane asked:


If you have a case study concerning the operation of a company, assuming you specialize in the area of Finance, and you are asked to identify all possible ways of a company raising funds. What would you suggest?

Hope these questions be answered entirely. Thanks.
Please note this is not a personal finance question. This question asks any possible ways of a corporate company raises funds to finance. List them if possible. Thanks.
