A website is a service that runs on the web.
For this service to reach users, it needs both an 'address' and a 'space'.

Understanding by analogy

• Domain · Like the address of a house (e.g., www.nineonelabs.co.kr)
• Web hosting · Like the space of a house — where the website actually runs and resides

Just as you lease an office or factory to use space for business, a website leases a dedicated space where its separately coded output can run. That space is web hosting.

Types of hosting

There are several kinds of hosting depending on purpose.

• Web hosting · General hosting for running a website
• Server hosting · Leasing by dedicated server unit
• Mail hosting · Dedicated to email send/receive
• Image hosting · Dedicated to static assets

Hosting for a website refers to 'web hosting' among these.
