Define what is memorandum

A memorandum (commonly referred to as a memo) is a written document that is used in business and other professional settings to communicate important information, policies, or decisions within an organization.

Memos are often used to provide updates, instructions, or reminders to employees, or to share information between different departments or levels of an organization. They are usually written in a more formal tone and can be distributed in either printed or digital formats. Memos generally include a heading, date, recipient, sender, subject, and body, and may also include attachments or references for further information.
