A web server is basically a battery of storage spaces that cater to a number of needs of the cyber space. In layman’s lingo, it’s a cluster of our very own hard disks which permanently remain connected to the internet. All the information that we see on the internet remains stored on these remote devices. These are large setups kept earmarked for specific tasks. The jobs that they do may be different depending on the requirements with many of them doing simultaneous functions at a time.
Ideally, web servers are mostly accessed when an entity requires hosting portal(s). The humble hard disk of a laptop or PC can also function as a server. Having said this, it is never advisable to do so for when it comes to providing services and resources to a plethora of computers and other devices such as smart phones, which is the basic job of a web server, the probability of a crash or data loss is inexplicably high.
Therefore, not getting into any risks it is always better to buy out a particular portion of a web server, most of the times at a certain amount of annual payment and let the whole process take a professional route. In the age of neck break competition, the payments have got a lot more cheaper with organizations offering different packages of web servers.
