what three application layer protocols are part of the tcp ip protocol suite choose three

by Rosie Kemmer Published 3 years ago Updated 2 years ago

(Choose three.) DNS, DHCP, and FTP are all application layer protocols in the TCP/IP protocol suite. ARP and PPP are network access layer protocols, and NAT is an internet layer protocol in the TCP/IP protocol suite.

Full Answer

What protocols operate at the application layer?

There are four layers to be considered:

Application layer - applications such as web browsers and email programs operate at this layer. ...
Transport layer - this breaks down the message into small chunks (packets). ...
Network layer - this adds the sender’s and recipient’s IP addresses to the packet, and packages the data to make it ready for transmission. ...

What are examples of application layer protocols?

The following list shows examples of application layer protocols:

Standard TCP/IP services such as the ftp, tftp, and telnet commands
UNIX “r” commands, such as rlogin and rsh
Name services, such as NIS and the domain name system (DNS)
Directory services (LDAP)
File services, such as the NFS service
Simple Network Management Protocol (SNMP), which enables network management

What are Layer 2 and Layer 3 protocols?

Zachary Williamson is a co-founder of Aztec Network, the first private ZK roll-up on ethereum.
He breaks down why ethereum layer-2 solutions will become a bigger deal in the year ahead.
He shares why developers have stuck with ethereum despite the rise of other layer-one protocols.

What is the principal protocol used to stream data across an IP network?

Principal protocol used to stream data across an IP network. The Transmission Control Protocol ( TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP.

What is a TCP segment?

The TCP segment is then encapsulated into an Internet Protocol (IP) datagram, and exchanged with peers.

How does TCP work?

TCP uses a number of mechanisms to achieve high performance and avoid congestion collapse, where network performance can fall by several orders of magnitude. These mechanisms control the rate of data entering the network, keeping the data flow below a rate that would trigger collapse.

Why does TCP use flow control?

TCP uses an end-to-end flow control protocol to avoid having the sender send data too fast for the TCP receiver to receive and process it reliably. Having a mechanism for flow control is essential in an environment where machines of diverse network speeds communicate. For example, if a PC sends data to a smartphone that is slowly processing received data, the smartphone must regulate the data flow so as not to be overwhelmed.

What is cumulative acknowledgment protocol?

In a pure cumulative acknowledgment protocol, the receiver can only send a cumulative ACK value of 2,000 (the sequence number immediately following the last sequence number of the received data) and cannot say that it received bytes 3,000 to 10,999 successfully. Thus the sender may then have to resend all data starting with sequence number 2,000.

What is the maximum segment size?

The maximum segment size (MSS) is the largest amount of data, specified in bytes, that TCP is willing to receive in a single segment. For best performance, the MSS should be set small enough to avoid IP fragmentation, which can lead to packet loss and excessive retransmissions. To try to accomplish this, typically the MSS is announced by each side using the MSS option when the TCP connection is established, in which case it is derived from the maximum transmission unit (MTU) size of the data link layer of the networks to which the sender and receiver are directly attached. Furthermore, TCP senders can use path MTU discovery to infer the minimum MTU along the network path between the sender and receiver, and use this to dynamically adjust the MSS to avoid IP fragmentation within the network.

How does TCP sequence work?

TCP uses a sequence number to identify each byte of data. The sequence number identifies the order of the bytes sent from each computer so that the data can be reconstructed in order , regardless of any packet reordering, or packet loss that may occur during transmission. The sequence number of the first byte is chosen by the transmitter for the first packet, which is flagged SYN. This number can be arbitrary, and should, in fact, be unpredictable to defend against TCP sequence prediction attacks .
