  • IP has only the mission of routing the datagram without checking the integrity of the information it contains.

TPC / IP PROTOCOL

  • Consent of basic communication protocols, networks, and the transmission of information achieve in computer networks.
  • This protocol is the one that provides the basis for the most used services such as file transfer, email, and remote login.
  • TCP / IP provides the basis for many valuable services, including email, file transfer, and remote login.
  • It also can provide security checks controlling transfers.
  • And also, It leaves the responsibility for a reliable transmission to exploit .
  • It allows an exchange of datagrams between applications and can choose those that do not demand many datagrams to operate optimally.

TCP PROTOCOL (TRANSMISSION CONTROL PROTOCOL)

  • It is geared towards communications and offers reliable data transmission.
  • TCP is in charge of assembling data from the upper layers to standard packets, ensuring that the data transfer carries out correctly.

ARP PROTOCOL (ADDRESS RESOLUTION PROTOCOL)

  • It aims to associate an IP device with a network device, which at the physical level has a network address.

  •  It achieves by eliminating sending unencrypts passwords by encrypting all information that is transmitted.
  • The SSH eliminates the sending of those passwords that are not encrypted and encrypting all the transferred information.
  • In addition to these specific functional protocols, it  identifies as standard or proprietary.
  • And also, It is free to use and consists of the systems most commonly used in the industry .
  • Developed by organizations that aim for the free use and continued development of the Internet for the benefit of the entire world,
