Question: Discuss about the OSI and TCP/IP Models System. Answer: Introduction: OSI or Open System Interconnection model is developed as a conceptual model for the computing system. It came out as a conceptual model that does not characterises or standardises all the internal structure of a networking system (Wu et al., 2013). While, TCP/IP is the protocol that works as the blood in the body of a computer network and also the architecture of the internet is TCP/IP based. The TCP/IP model is divided in four layers. On the other hand, the OSI layer is made of seven layers. The discussion is about comparison of this two communication models to find out the layer protocols that corresponds to each other, reliability of the model and the roles of the host systems in the network (Wang et al., 2014). OSI (Open System Interconnection) TCP/IP (Transmission Control Protocol/ Internet Protocol) Its network layer provides both connectionless as well as connection oriented services Its network layer provides only connectionless services It is used as a reference or guidance around which the network model is developed It is an implementation of the OSI model It is an independent standard of the protocols that allows communication between the user and the network It is a standard protocol around which the internet is developed it allows the communication between the nodes in a network It has two different layers as Presentation and Session layer. It does not have two different layers for Presentation and Session layer. It comprises with seven layers It comprises with four layers It defines its protocols and interfaces very clearly that makes it protocol independent Its protocols are not clearly distinguishable that makes it protocol dependent Along with the technological changes OSI layer protocols are easy to replace. In TCP/IP replacing protocol is not easy. Its transport layer guarantees the delivery of the packet Its transport layer does not guarantees the delivery of the packet however it is more reliable It follow a vertical manner It follow a horizontal manner Pros and Cons of IPv4 and IPv6 IPv4 stays for Internet Protocol variation 4. It is the major development that makes it doable for us to interface our devices to the web. At whatever point a device get to the Internet, it is named a remarkable, numerical IP address, for instance, 99.48.227.227. To send data beginning with one PC then onto the following through the web, a report package must be traded over the framework containing the IP areas of the two contraptions (Richter et al., 2015). Without IP addresses, PCs would not have the ability to affect and send data to each other. It's fundamental to the structure of the web. IPv6 is the 6th adjustment to the Internet Protocol, and it is the successor to the IPv4. It follows the new numerical IP and keeps an eye out for basic for Internet-empowered contraptions to offer. Regardless, it sports one extraordinary complexity: it utilises 128-piece addresses (Kumar, Dalal Dixit, 2014). I'll clear up why this is fundamental for a moment. IPv4 uses 32 bits of data for its Internet addresses. That suggests it can reinforce 2^32 IP tends to through and through around 4.29 billion. That may seem like an incredible arrangement. In any case, each of the 4.29 billion IP addresses has now been consigned to various establishments, provoking the crisis we stand up to today (Goralski, 2017). We should come to the heart of the matter, be that as it may: we haven't missed the mark on addresses yet. A remarkable number of them are unused and in the hands of foundations like MIT and associations like Ford and IBM. More IPv4 conveys available to be doled out, and more will be traded or sold, yet they will wind up being a scarcer product all through the accompanying two years until the point that the moment that it makes the issue for the web. As effectively communicated, IPv6 utilises 128-piece Internet addresses. Subsequently, it can reinforce 2^128 IP addresses 340,282,366,920,938,000,000,000,000,000,000,000,000 of them to be ri ght. That is a significant measure of addresses, such an expansive number of, to the point that it requires a hexadecimal structure to demonstrate the addresses. Today we have to go over the distinctive upsides and drawbacks of providers changing over to IPv6. It has some stamped central focuses and some also troublesome obstacles. IPv4 had one large issue. Deficient IP conveys to track everyone in a framework. Or, on the other hand in an all the all the more interesting sense, lacking delivers to follow everyone in all frameworks. This in like manner incited coordinating bothers and software engineer issues. IPv6 attempts to select everyone postage data to help for the better after, speedier controlling and overall better execution (Czyz et al., 2014). It does what it says it does. Speedier speed is guaranteed on account of better controlling and direct data stream. The extended number of addresses makes things harder for accommodating developers. Both security and speed are staggeringly upgraded by this structure. It moreover contains no IP-level checksum decreasing information exchange limit utilise. It is in like manner incredibly easy to setup sorts out on this set as well. Finally, it gives distinctive Internet Control Message Protocols making it incredibly secure. On a mechanical level, it works better i n about every way (Alani, 2014). IPv6, nonetheless, raises security concerns. The IP provider can supply IP for each of the systems. This is useful for an arrangement of reasons including: Using someone else's relationship with get them sued or caught Tracking an individual actually Throttling information exchange limit and confining customers Providing information to the police for criminal exercises Providing information to the organisation Giving information to gigantic business for claims Various customers have voiced their stresses over this. We are thinking about how the assembly will charge cases in which someone has been encompassed. Different people are in like manner stressed over how this will be dealt with. Used as a piece of the most detectably terrible way IPv6 could transform into an Orwellian awful dream. Mechanically the system offers a universe of substantial purposes of intrigue (Bora et al., 2014). If used actually, it could incite an artificial lift in the speed of the web. In any case, if it is misused individual information, reputations or even lives could be being referred to. General society should keep an eye out for how extensive business and the organisation handle this structure. The same could be said of our present structure, which see on a broad scale is starting at now possible in. References Alani, M. M. (2014). TCP/IP model. InGuide to OSI and TCP/IP models(pp. 19-50).
