From
Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encryption and secure identification of the server. HTTPS connections are often used for payment transactions on the World Wide Web and for sensitive transactions in corporate information systems.
Do i need https?
This entirely depends on the type of site that you are using. If you have sensitive data then use https.
How can i install it?
You have to get SSL certificates from a Cettificate Provide like Thawte, Verisign etc and have to install the certificate in your application.

A:
HTTPS is representative of a secure connection, typically used when your dealing with shopping carts, credit card numbers, etc. To get set up, you'll need an SSL Certificate. You should speak with your host about this matter.

To generalise, any transaction of sensitive data should use this secure method of communication. :)

A:
HTTPS is a protocol for securing the information sent from the people using your website to your web server.
You only need it if you have them enter sensitive information such as credit cards, social security numbers, etc.
If you are not dealing with this type of information, you do not need it.
If you do need https because you have sensitive information being entered in your website, your web hosting company can help you set it up. There is generally an additional cost involved.

FYI Ryan you probably got the downvote because you just reference something else without adding any additional insight (it wasn't me though... just trying to help for your next answer).

https is the secure (meaning encrypted transfer of content both ways) version of html.
your application needs it, if you must be certain no one reads what is being send/received.
most web server support https, and your application might, depending on the libraries you used to communicate.

A:
HTTPS is HTTP over SSL (encrypted connection).
SSL certificates are free, getting them signed by a known Certificate Authority isn't free, nor cheap. Getting them signed means that the browser won't complain when a user will visit your site. Unsigned ones are as safe as the signed ones tho.
And you do need them if you ask for sensitive information from your users or if you give them sensitive info.
