Every time a visitor opens your website, the web browser sends a request to the hosting server, which in turn executes it and gives the desired data as a response. A basic HTML website uses minimum resources as it's static, but database-driven platforms are more demanding and use a lot more processing time. Every page that's served creates 2 kinds of load - CPU load, that depends on the length of time the hosting server spends executing a certain script; and MySQL load, which depends on the number of database queries created by the script while the end user browses the website. Greater load shall be produced if a whole lot of people surf a particular site at the same time or if numerous database calls are made simultaneously. 2 illustrations are a discussion board with a large number of users or an online store where a visitor enters a term inside a search box and tens of thousands of items are searched.
