http,https, hypertext transfer protocol and secured
- 2. Lesson objectives Today we will learn http and https Purpose of http and https 2
- 3. Http and its purpose HTTP stands for HyperText Transfer Protocol. It is invented by Tim Berner. HyperText is the type of text which is specially coded with the help of some standard coding language called HyperText Markup Language (HTML). HTTP provides a standard between a web browser and a web server to establish communication. It is a set of rules for transferring data from one computer to another. 3
- 4. Http continued Data such as text, images, and other multimedia files are shared on the World Wide Web. Whenever a web user opens their web browser, the user indirectly uses HTTP. It is an application protocol that is used for distributed, collaborative, hypermedia information systems. 4
- 5. Http characteristics HTTP is IP based communication protocol that is used to deliver data from server to client or vice-versa. Any type of content can be exchanged as long as the server and client are compatible with it. It is a request and response protocol based on client and server requirements. 5
- 6. HTTPS HTTPS stands for Hyper Text Transfer Protocol Secure. HTTP Secure (HTTPS), could be a combination of the Hypertext Transfer Protocol with the SSL/TLS convention to supply encrypted communication and secure distinguishing proof of an arranged web server. HTTPS is more secure than HTTP because HTTPS is certified by the SSL(Secure Socket Layer). website you are visiting on the internet, if its URL is HTTP, then that website is not secure. 6
- 7. Characteristics of HTTPS HTTPS encrypts all message substance, including the HTTP headers and the request/response data. The verification perspective of HTTPS requires a trusted third party to sign server-side digital certificates. HTTPS is presently utilized more frequently by web clients than the first non-secure HTTP, fundamentally to ensure page genuineness on all sorts of websites, secure accounts and to keep client communications. 7
