Why Do I Need Hosting?
You might be asking yourself: “If hosting really just consists of a computer that serves a website, then why do I need a hosting service? Can’t I just have my home computer host my website?”

Yes, you could, but that would be a really bad idea — I mean*****really*****bad. There are many reasons web hosts exist and their low cost and high performance make them affordable for everyone, not to mention headache-free.
Web Hosts to the Rescue
a) Redundant Power Supplies*****– The power supplies at most web hosts are almost always backed up by on-site generators that keep sites live even in extreme power outages.
b) Ultra-Fast, Stable Connections*****– Web hosts have extremely fast upload speeds and can serve hundreds, thousands, or tens of thousands of concurrent visitors easily.
c) Static IP Address*****– With a web host, you can have a dedicated IP that will never change. This means your address always stays the same and people can always find your site.
d) Expert Team Maintaining Hardware*****– The experts at these web hosts constantly maintain the hardware and have replacement parts on hand. They also have redundant hardware and back up your files for you.

Now, in this Growing world it becomes very important to show your Presence in the industry
Hence hosting is very Important
