What TCP IP means?
Transmission Control Protocol/Internet Protocol
TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet).
What are the 4 levels of TCP IP?
4 The TCP/IP Protocol Stack is made up of four primary layers: the Application, Transport, Network, and Link layers (Diagram 1). Each layer within the TCP/IP protocol suite has a specific function.
What are the 5 TCP IP layers?
The TCP/IP model is based on a five-layer model for networking. From bottom (the link) to top (the user application), these are the physical, data link, net- work, transport, and application layers.
How TCP IP model works?
How it works. TCP/IP is a two-layered program: the higher layer (TCP) disassembles message content into small “data packets” that are then transmitted over the Internet to be re-assembled by the receiving computer’s TCP back into the message’s original form.
What are ports in TCP?
A port is a number used to uniquely identify a transaction over a network by specifying both the host, and the service. They are necessary to differentiate between many different IP services, such as web service (HTTP), mail service (SMTP), and file transfer (FTP).
What layer is TCP at?
In terms of the OSI model, TCP is a transport-layer protocol. It provides a reliable virtual-circuit connection between applications; that is, a connection is established before data transmission begins.
What port is IP?
IP Address vs Port Number –
|IP ADDRESS||PORT NUMBER|
|Used to identify a host||Used to identify an application/services on your system|
|An IP address is the address of the layer-3 IP protocol.||A port number is a layer-4 address used by some layer-4 protocols e.g. TCP and UDP|
What is TCP port range?
Port numbers range from 0 to 65535, but only port numbers 0 to 1023 are reserved for privileged services and designated as well-known ports.
