A record data type represents a data type for that row in a database table. It lets u define your own records and not your own fields.

- Infinite file consists of random bits of code that is stored in /dev/random file used to generate the cryptographic keys. 

- Infinite file consists of the source of infinite data that can be used to provide the response in easy manner. 

- Web server consists of the file that is received by the server in this format GET //dev/random HTTP/1.0. 

- Web server provides the continuous data that can be read from /dev/random/ before the web server can run out of the memory. 

- The server crashes out in case it runs out of the memory due to the infinite file type and it is very essential in case of the web security.

- The traffic can be measured using the size of the files that are transferred from one place to another (server-client). 

- It can also be measured by the size of the file that is being requested by the client from the server. 

- The number of visitors arriving on the website also involve in the measurement of the traffic using the web hosting platform. 

- The advertisements of the sites take more bandwidth to allow more number of users to be on the website. 

- More number of users provides higher traffic on the website thus it requires more bandwidth on the web hosting sites.
