Can you tell me the differences between a letter and a memorandum, Miss Thong?
Certainly. A letter must be sent out of the company and must be mailed or posted. A memorandum is a communication within an organization.
Should we use the layout we use for a letter when we write a memorandum?
No, not necessary. Usually we have a set form which is printed. We just fill in the printed forms and send it to the person or the offices concerned in the company.
