Web hosting is the service of storing data that keeps websites up and running for users. Every single website that is online has a host server, and almost all use a web host to manage that storage. Not all web hosts provide the same level of quality, though. Uptime, and data speed and quantity of transfer are the best measures of a host’s success. You can often pay more to get data transferred in higher quantities, faster. Most web hosts offer unlimited bandwidth and disk space at a speed that is perfectly fine for small-to-moderate sized businesses or individuals. For companies with burdensome websites, they may need to seek out a more advanced web host.
