Which protocol is used to transfer Web pages from a server to a client device?

Hypertext Transfer Protocol (HTTP)

Which protocol operate at the application layer of the OSI model Choose 2?

Explanation: FTP, DHCP, and POP3 are application layer protocols. TCP and UDP are transport layer protocols.

What application layer protocol is commonly used to support for file transfers?

HyperText Transfer Protocol (HTTP) 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.

What are the 2 forms of application layer software?

Application Layer Software Within the application layer, there are two forms of software programs or processes that provide access to the network: applications and services.

What protocols are used in IoT?

Overview of IoT protocols

Message Queuing Telemetry Transport (MQTT)
ZigBee.
Bluetooth.
Extensible Messaging and Presence Protocol (XMPP)
Data-Distribution Service (DDS)
Advanced Message Queuing Protocol (AMQP)
Lightweight M2M (LwM2M)

What is Application Layer example?

A few examples of application layer protocols are the Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Post Office Protocol (POP), Simple Mail Transfer Protocol (SMTP), and Domain Name System (DNS). The presentation layer prepares data for the application layer.

What happens in application layer?

Application layer interface directly interacts with the application and provides common web application services. The application layer also makes a request to the presentation layer. Application layer is the highest level of open systems, providing services directly for the application process.

What is application layer message?

Application layer message: HTTP, SMTP, and FTP protocols are used in application layer. it is used to send data over multiple end systems. Transport layer segment: Transfer the content between two endpoints mainly. TCP and UDP protocols are used in transport layer.

Does Netflix use UDP?

Netflix, Hulu, Youtube, etc. video streaming all use TCP and simply buffer a few seconds of content, instead of using UDP since the delay is not crucial and TCP transfers can be easily accomplished over HTTP and web browsers without the need for additional plugins and software.

Which one of the following is a version of UDP with?

7. Which one of the following is a version of UDP with congestion control? Explanation: The datagram congestion control is a transport layer protocol which deals with reliable connection setup, teardown, congestion control, explicit congestion notification, and feature negotiation.

Is TCP more secure than UDP?

TCP isn’t more secure than UDP, it is more “reliable” as it is stateful and requires acknowledgment of each segment. UDP is stateless and just sends segments without knowing of the client gets them or not.

What is the difference between TCP and UDP why would you use one over the other?

KEY DIFFERENCES: TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. TCP does error checking and also makes error recovery, on the other hand, UDP performs error checking, but it discards erroneous packets.

Why UDP is not secure?

The big security problem with UDP is that you are susceptible to spoofing and DOS attacks. It’s not possible to spoof an address across the internet using TCP since the handshake will never complete. OTOH with UDP there is no implicit handshake – any session maintenance must be done by your code (processing overhead).
