How does HTTP and TCP work?

When HTTP wants to transmit a message, it streams the contents of the message data, in order, through an open TCP connection. TCP takes the stream of data, chops up the data stream into chunks called segments, and transports the segments across the Internet inside envelopes called IP packets (see Figure 4-4).

Is HTTP a TCP protocol?

Designed in the early 1990s, HTTP is an extensible protocol which has evolved over time. It is an application layer protocol that is sent over TCP, or over a TLS-encrypted TCP connection, though any reliable transport protocol could theoretically be used.

When should you use HTTP vs TCP?

HTTP is a protocol used mostly for browsing the internet (IE, Firefox, etc). It rides on top of TCP which provides a reliable link between two computers (if packet get lost – it is re-transmitted). TCP itself rides on top of IP, which provides unified addressing to communicate between computers.

Does HTTP use TCP protocol?

HTTP and connections Among the two most common transport protocols on the Internet, TCP is reliable and UDP isn’t. HTTP therefore relies on the TCP standard, which is connection-based.

What protocol uses both TCP and UDP?

Both TCP and UDP use ports and port numbers to identify application protocols. For example, Web services (HTTP) use port 80, FTP uses port 21, and Gopher uses port 70. A typical session involves sending packets from a source IP address and port to a destination IP address and port.

Is UDP protocol the same thing as TCP?

TCP and UDP are two protocols that are part of the transport layer in a TCP/IP model of data transmission. Both share the same core function – transmitting data packets from the client to the server and vice versa. But it is the difference between TCP and UDP protocols which make them appropriate for specialized requirements.

What is standard TCP port?

TCP port 443 is the standard TCP port that is used for website which use SSL . When you go to a website which uses the https at the beginning you are connecting to port 443.

What does TCP IP mean?

TCP/IP stands for Transmission Control Protocol/Internet Protocol, which is a set of networking protocols that allows two or more computers to communicate.
