Which Of The Following Statements Are True About The Tcp Service Model

The TCP/IP model is a part of the Cyberspace Protocol Suite. This model acts as a communication protocol for computer networks and connects hosts on the Internet. It is a concise version of the OSI Model and comprises four layers in its construction.

This concept of TCP/IP is non just of import for people in the calculator or It fields but also is an essential role of the Computer Noesis syllabus, included in major competitive exams.

Before, diving deep into the different aspects of the construction, refer to the tabular array beneath and know nearly some basic and introductory features of the model:

Basics of TCP/IP Model
Full-Class	Manual Control Protocol/ Internet Protocol
Developed By	Section of Defence (DoD), United states
Developed in	During the 1970s
Year for acknowledgement every bit a standard protocol by ARPANET	1983
Function of TCP	Collecting and Reassembling Data Packets
Office of IP	Sending the Data Packets to the correct destination
Number of Layers in TCP/IP Model	4 layers

In this commodity, we shall discuss in detail the different layers of the TCP/IP model along with their functions. Also, a few sample questions based on this topic take been given further below for the reference of Government test aspirants.

History and Development of TCP/IP Model

This protocol is a result of the inquiry and evolution past the Defense Advanced Inquiry Projects Agency (DARPA) during the 1960s. Given below are a few points which had played an important office in the advocacy of the TCP/IP model:

• A two-network TCP/IP communications examination was conducted betwixt Stanford and University College London in 1975
• An important affair which resulted in promoting this model was when the Usa Department of Defense declared TCP/IP as the standard for all military machine computer networking. This was In March 1982
• In 1983, this structured protocol was adopted by ARPANET equally a standard protocol
• Later on other Computer and IT companies including IBM, Dec, etc. had also adapted the TCP/IP model as their standard communication protocol
• In 1989, the University of California has accepted the TCP/IP code for public domain

Gradually, this Net protocol suite or the TCP/IP model was accepted across the globe as a comprehensive framework for computer networking and Internet communication.

The TCP/IP model is considered to exist like to the Open Systems Interconnection Model. Still, the framework and the structuring of the two was completely different and Transmission Control Protocol/ Net Protocol was released prior to the OSI Model. For a detailed difference between the two, candidates tin visit the Divergence Between TCP/IP and OSI Model page.

Links to a few other primal topics and concepts have been given below for people to larn and empathise one of the most complex, yet essential devices, which is the Computer:

Layers of the TCP/IP Model

Dissimilar the OSI model which comprises seven layers, the TCP/IP model is structured with four different layers. These four layers are:

1. Network Access Layer
2. Net Layer
3. Host to Host Layer
4. Application Layer

Now, allow u.s. discuss each of these four layers in detail along with their functions every bit a part of the protocol architecture.

• This is the lesser-most layer of the TCP/IP model compages
• Information technology is a combination of the Data Link and Concrete Layer of the OSI model
• The physical transmission of information takes place at this layer
• Once the frames are transmitted by a network, encapsulating the IP datagram into these frames is done in this layer
• Also, the mapping of IP accost into concrete address is done here
• Mainly, the role of this layer is to transmit the data between ii devices, connected in a network

• It is the second layer of the TCP/IP model and this layer is parallel to the Network Layer of the OSI Model, in terms of the construction
• Sending the data packets to their destination network is the main part of the Cyberspace layer
• The logical transmission of data takes place at this level
• There are three dissimilar protocols used in this layer. These include:
  • IP: One of the most of import protocols as it detects the IP address of a device which is later used for internetwork connections. It is using this protocol that the path with which the data shall be transmitted is decided. There are two common IP versions which are used, To know the difference betwixt IPv4 and IPv6 , visit the linked article.
  • ARP: It stands for Address Resolution Protocol. The concrete accost from the IP address can be determined using ARP.
  • ICMP: It stands for Cyberspace Control Message Protocol and notification regarding datagram problems can be sent back to the user using this. Whatsoever issue with the network is immediately notified to the user by ICMP. Information technology can only inform the user about the errors and cannot rectify the problem

• This layer is parallel to the send layer of the OSI Model
• The error-free delivery of data is the principal office of this layer
• There are ii principal protocols nowadays in this layer:
  • TCP: Another integral part, the Transmission Control Protocol is a reliable communication protocol. Information technology manager the menstruum of data, i.e. the sequence and segmentation of the information
  • UDP: Information technology is a connection-free protocol which makes it toll-effective but less reliable.

• The topic three layers of the OSI Model: Awarding, Presentation and Sessions, when combined together, they perform like functions every bit the Awarding Layer of the TCP/IP model
• node-to-node communication based on the user-interface occurs here
• Multiple protocols are present in this layer, a few mutual ones take been mentioned below in brief:
  • HTTP: Hypertext Transfer Protocol is used to manage the advice betwixt the server and web browsers
  • NTP: Network Fourth dimension Protocol can fix ane standard time source in our computer, which enables sync between the server and the user
  • TELNET: Telecommunication Network is used to have access to files present of the Telnet network and manage them on net
  • FTP: File Transfer Protocol, every bit the proper name suggests allows easy transferring of files

Other protocols of Application layer include Network File System (NFS), Secure Crush (SSH), Simple Postal service Transfer Protocol (SMTP), Trivial File Transfer Protocol (TFTP), etc.

Sample Questions – TCP/IP Model

Since questions from this topic are asked in the Computer Awareness section of the major Government exams, candidates must be well prepared for the concept from the exam perspective as well.

Thus, to banana candidates with their grooming, given below are a few sample questions based on the TCP/IP model, in the format of the multiple-pick questions, as asked in the concluding examination.

Candidates who are looking for written report cloth and grooming strategy for the upcoming exams, they tin refer to the links given below and start their preparation now:
