The majority of people use the internet to make purchases and research information, so it is important that we know what the protocols used when accessing websites are:

• Hypertext Transfer Protocol (HTTP): Used to access websites, no matter whether you are using Internet Explorer, Chrome, Firefox, or Microsoft Edge.
• Hypertext Transfer Protocol Secure (HTTPS): When you are using HTTP and adding items to your shopping cart, you will then be diverted to a secure server that uses HTTPS so that your session is secure and you can then enter your credit or debit card details.
• Transport Layer Security (TLS): An upgraded version of SSL that is used to encrypt communications on the internet and transfer data securely, such as email or internet faxing. HTTPS is a common instance of it.
