HTTP vs HTML HTML: hypertext markup language Definitions of tags that are added to Web documents to control their appearance HTTP: hypertext transfer protocol The rules governing the conversation between a Web client in addition to a Web server Both were invented at the same time by the same person What is a protocol In diplomatic circles, a protocol is the set of rules governing a conversation between people We have seen that the client in addition to server carry on a machine-to-machine conversation A network protocol is the set of rules governing a conversation between a client in addition to a server There are many protocols, HTTP is just one

I would like to open a connection GET Display response Close connection OK Send page or error message OK Client Server HTTP is the set of rules governing the as long as mat in addition to content of the conversation between a Web client in addition to server An HTTP conversation An HTTP example The message requesting a Web page must begin with the work “GET” in addition to be followed by a space in addition to the location of a file on the server, like this: GET /fac/lpress/shortbio.htm The protocol spells out the exact message as long as mat, so any Web client can retrieve pages from any Web server. Network protocols The details are only important to developers. The rules are defined by the inventor of the protocol – may be a group or a single person. The rules must be precise in addition to complete so programmers can write programs that work with other programs. The rules are often published as an RFC along with running client in addition to server programs. The HTTP protocol used as long as Web applications was invented by Tim Berners Lee. RFC = request as long as comments

Tim Berners-Lee Tim Berners-Lee was knighted by Queen Elizabeth as long as his invention of the World Wide Web. He is shown here, along with the first picture posted on the Web in addition to a screen shot from an early version of his Web browser. HTTP is an application layer protocol The Web client in addition to the Web server are application programs Application layer programs do useful work like retrieving Web pages, sending in addition to receiving email or transferring files Lower layers take care of the communication details The client in addition to server send messages in addition to data without knowing anything about the communication network The application layer is boss – the top layer Your boss says: Send this package to Miami – I don’t care if you use Federal Express, UPS, or any other means. Also, let me know when it arrives or if it cannot be delivered as long as some reason. The application program says: Send this request to the server – I don’t care how you do it or whether it goes over phone lines, radio, or anything else about the details. Just send the message, in addition to let me know when it arrives or if it cannot be delivered as long as some reason. There are five TCP/IP layers, the application layer in addition to four lower layers.

Many application layer protocols are used on the Internet, HTTP is only one The TCP/IP protocol layers Get useful work done – retrieve Web pages, copy files, send in addition to receive email, etc. Make client-server connections in addition to optionally control transmission speed, check as long as errors, etc. Route packets between networks Route data packets within the local area network Specify what medium connects two nodes, how binary ones in addition to zeros are differentiated, etc, The application program is king – it gets work done using the lower level layers as long as communication between the client in addition to server. Food as long as thought What would happen if a Web client was poorly programmed in addition to instead of sending a message beginning with “GET” it sent a message beginning with “QET”
