Which two protocols operate at the highest layer of the TCP/IP protocol stack? (Choose two.) Explanation: The application layer is the top layer of the TCP/IP protocol stack. Application layer protocols include HTTP, DNS, HTML, TFTP, POP, IMAP, FTP, and SMTP.
Simply so, which two protocols are TCP IP application layer protocols?
It is responsible for node-to-node communication and controls user-interface specifications. Some of the protocols present in this layer are: HTTP, HTTPS, FTP, TFTP, Telnet, SSH, SMTP, SNMP, NTP, DNS, DHCP, NFS, X Window, LPD. Have a look at Protocols in Application Layer for some information about these protocols.
Secondly, what are two services provided by the OSI network layer choose two? Routing packets toward the destination. Encapsulating PDU's from the transport layer.
Considering this, which transport layer protocols are found in the TCP IP suite?
Transport layer protocols at this level are Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Stream Control Transmission Protocol (SCTP). TCP and SCTP provide reliable, end-to-end service.
What are the concerns of a physical layer in TCP IP protocol suite?
Encoding and Signaling: The physical layer is responsible for various encoding and signaling functions that transform the data from bits that reside within a computer or other device into signals that can be sent over the network.
Similar Question and The Answer
What layer is HTTP?
application layer
What layer is FTP?
File Transfer Protocol(FTP) is an application layer protocol which moves files between local and remote file systems. It runs on the top of TCP, like HTTP. To transfer a file, 2 TCP connections are used by FTP in parallel: control connection and data connection.
Is DNS an application layer protocol?
Protocols at the Physical, Data-Link, Network, or Transport layers do not use names. Only applications need to use names, so DNS is an application-layer protocol because it allows the application to translate a name into a network address.
What is application layer in TCP IP?
In TCP/IP, the application layer contains the communications protocols and interface methods used in process-to-process communications across an Internet Protocol (IP) computer network. The OSI model defines the application layer as the user interface responsible for displaying received information to the user.
What OSI layer is TCP?
transport layer
What layer is SMTP?
application layer
Is http an application layer protocol?
HTTP is an application layer protocol used for transferring information between computers on the World Wide Web. HTTP is based on a request/response standard between a client; usually the host and a server, a web site.
Where is TCP IP used?
TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private network (an intranet or an extranet).
What are the functions of transport layer?
Transport layer is the 4th layer in TCP/IP Model that deals with logical communication between process. It is responsible for delivering messege between network host. It also accept data from application layer and prepare it for addressing at network layer.
What layer is DNS?
In OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit "below" HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.
What are the duties of transport layer?
The transport layer is the layer in the open system interconnection (OSI) model responsible for end-to-end communication over a network. It provides logical communication between application processes running on different hosts within a layered architecture of protocols and other network components.
What layer is UDP?
Transport Layer
How many layers are there in TCP IP protocol suite?
4 layers
What are the two main transport layer protocols?
Transport Layer protocols. The transport layer is represented by two protocols: TCP and UDP. The IP protocol in the network layer delivers a datagram from a source host to the destination host. Nowadays, the operating system supports multiuser and multiprocessing environments, an executing program is called a process.
