The importance of seminars is the wealth of knowledge presented and gained during them. A seminar is a presentation, set on a particular topic or group of topics, put forth by an expert in the field.
Seminars are important and beneficial for those who have difficulty learning in a typical classroom setting where reading and writing are required. There is often a sense of friendship associated with seminar attendance, because everyone is attending with a like interest in learning about a subject important to them. A seminar is usually designed for at least 10 attendees and up, though there are no concrete standards dictating size requirements. They are held in a myriad of places from hotels to office conference rooms, fluctuating based upon the number of people attending.
