A Content Delivery Network (CDN) is a group of geographically distributed servers that deliver the web content closer to the user's location. It stores a temporary cached version of the website content in multiple geographical locations across the globe. We call these points of presence (PoPs). They deliver the content close to the user's location, enable high-speed web content hosting, and enhance uptime.  Suppose you're searching for a London-based website sitting in the United States. Your request will travel across the Atlantic Ocean to obtain the information. Because your request travels, your website loads slowly. A CDN distributes and stores all website information to various local servers that can bring the information to you faster.
