• The availability of the website shows the reliability of the website and it is measured by the usability and accessibility of the user in a year.
• This measures the availability that tells about the reachable sources to the website in a given period of time.
• The availability can be measured by using the following formula:
• Total time = 365 days per year * 24 hours per day * 60 minutes per hour = 525,600 minutes per year
• Uptime is a method that is used to refer to a system that is already having online presence and there is some event occurring on the network.

Uptime is the percentage of time that a web site is working. For example, if some host has an uptime average of 99.86%, this means that your site will be down for a total about 1 hour each month.

• CGI scripts allow the communication to be done between the client and the server side and it acts as a gateway between them.
