If you want your website to be live you need to sign up with a web hosting company. The web hosting company (server) stores your webpages and when your domain name is typed into the web browser it links it to your IP address (a number assigned to you by your internet serves provider) that points it to a specific computer. If a person surfing the internet asking for your page the hosting company goes through your stored webpages.
Websites that want to go live need a web host or server that houses a remote computer. Files and pages from multiple websites are stored on the remote computer. This is a shared server.
Disk Space and bandwidth are the two most important considerations when deciding what web hosting company you are going to use.
Disk space is the amount of storage space you have on your hard disk at the hosting company. It is used to store all your graphics, documents, animation etc. It is easy to determine how much disk space your website will need, you just have to see how much space it is taking on your local disk that is found on your personnel computer.
Bandwidth is not the same as disk space, although many people get confused with these two terms. The amount of bits/data that can be downloaded from your web site is called bandwidth. You are usually allocated a certain amount per month, when this is used up; Until the next month's allocation your webpage will not be up for viewing. This is not good for business. Bandwidth also controls the speed at which you webpages load.
A web hosting company that has the latest technology at the most competitive rate should be your first choice. Upload your files and pages to the webspace of your web hosting company, so that they can store and distribute them as needed. To do this you need to upload your website. Sending files from your local computer to the web hosting server is called uploading. You upload files with a FTP Client.
Now that you have uploaded your website, all that is left for you to do is manage the traffic it will bring and updating your website frequently by adding new and interesting content.
