Here, hierarchical means that each upper-layer protocol is supported by two or more lower-level protocols. Show
Functions of TCP/IP layers:Network Access Layer
Internet Layer
Following are the protocols used in this layer are:IP Protocol: IP protocol is used in this layer, and it is the most significant part of the entire TCP/IP suite. Following are the responsibilities of this protocol:
ARP Protocol
ICMP Protocol
Transport LayerThe transport layer is responsible for the reliability, flow control, and correction of data which is being sent over the network. The two protocols used in the transport layer are User Datagram protocol and Transmission control protocol.
Application Layer
Following are the main protocols used in the application layer: HTTP: HTTP stands for Hypertext transfer protocol. This protocol allows us to access the data over the world wide web. It transfers the data in the form of plain text, audio, video. It is known as a Hypertext transfer protocol as it has the efficiency to use in a hypertext environment where there are rapid jumps from one document to another.SNMP: SNMP stands for Simple Network Management Protocol. It is a framework used for managing the devices on the internet by using the TCP/IP protocol suite.SMTP: SMTP stands for Simple mail transfer protocol. The TCP/IP protocol that supports the e-mail is known as a Simple mail transfer protocol. This protocol is used to send the data to another e-mail address.DNS: DNS stands for Domain Name System. An IP address is used to identify the connection of a host to the internet uniquely. But, people prefer to use the names instead of addresses. Therefore, the system that maps the name to the address is known as Domain Name System.TELNET: It is an abbreviation for Terminal Network. It establishes the connection between the local computer and remote computer in such a way that the local terminal appears to be a terminal at the remote system.FTP: FTP stands for File Transfer Protocol. FTP is a standard internet protocol used for transmitting the files from one computer to another computer.Which protocols are found in transport layer of TCP IP model?Transport layer protocols at this level are Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Stream Control Transmission Protocol (SCTP).
Which protocol uses TCP as its transport layer protocol?As mentioned earlier, TCP is the most common transport layer protocol. It is used by many application layer protocols like the HyperText Transfer Protocol (HTTP) and FTP. TCP was designed to provide reliable service on top of the unreliable network layer provided by IP.
Which of the following protocols are examples of TCP IP network access layer protocols?It is a framework used for managing the devices on the internet by using the TCP/IP protocol suite. SMTP: SMTP stands for Simple mail transfer protocol. The TCP/IP protocol that supports the e-mail is known as a Simple mail transfer protocol. This protocol is used to send the data to another e-mail address.
