A student is uploading files from a phone to a server on another network. which layer of the tcp/ip model is responsible for providing an addressing scheme to transmit the data between the devices?

By • Transworld Data • Senior Managing Editor • Editorial Director What is TCP/IP? TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in a private computer network (an The entire IP suite -- a set of rules and procedures -- is commonly referred to as TCP/IP. . The TCP/IP protocol suite functions as an abstraction layer between internet applications and the routing and switching fabric. TCP/IP specifies how data is exchanged over the internet by providing end-to-end communications that identify how it should be broken into The two main protocols in the IP suite serve specific functions. TCP defines how applications can create channels of communication across a network. It also manages how a message is assembled into smaller packets before they are then transmitted over the internet and reassembled in the right order at the destination address. IP defines how to address and route each packet to make sure it reaches the right destination. Each gateway computer on the network A subnet mask tells a computer, or other network device, what portion of the Network address translation (NAT) is the virtualization of IP addresses. NAT helps improve security and decrease the number of IP addresses an organization needs. Common TCP/IP protocols include the following: • Hypertext Transfer Protocol (HTTP) handles the communication ...

Computer Networks are a beautiful, amazing topic. Networks involve so much knowledge from different fields, from physics to algorithms. When dealing with Computer Networks, there is one framework that puts everything into place – and that is the layers model. In this post you'll learn why we need layers, as well as what the five layers model is. You will also understand the role of each layer in this model. Why Layers? Imagine you are given the task to design and implement the Internet! Where do you start? What do we actually want from a network, and an important one such as the Internet? Well, we actually want quite a lot of things. To name a few: • We want it to be fast – that is, allow fast communication. We don’t want to wait long for a message to get from one host to another. • It should also be reliable – when sending a message, we want the receiver to actually receive it. • The network should be extendable – that is, allow more devices to join. We wouldn’t want to start with two computers, and then not bee able to add a third one. • The network should support different devices and connections – it should be able to connect a wired PC, wireless laptop, and a cellphone, for example. And this is just a partial list. So, how do we go about implementing the internet when we want to achieve so many different things? Computer Networks are complex (Source: In order to simplify things and make networks flexible, the communication is divided into layers. Each layer has its ow...

Whenever you connect two devices either on the same or different networks, a question may arise in your mind regarding the connectivity of the devices. The two devices may have different architecture and implement different Actually, they need a standardized model that can be implemented by both to establish a connection between them. There are also some standardized protocols that they can implement to connect. So, In this blog, we will learn about a widely accepted standardized model, i.e., the OSI(Open System Interconnection) model. We will also learn the mechanism, how two devices are connected using this model. We'll also focus on the different layers of this model along with their functionalities. OSI Model OSI model is a layered framework that allows communication between all types of the computer system. It has seven layers. OSI model is introduced by ISO(International Organization for Standardization) in 1984. Each layer has its own functionalities and calls upon the services of the layer just below it. These layers are a package of In other words, the OSI model defines and is used to understand how two computers connect with each other in a computer network. The seven layers of the OSI model, are as follows: • Physical Layer • Data-Link Layer • Network Layer • Transport Layer • Session Layer • Presentation Layer • Application Layer We will learn about these layers and their functionalities one by one. 1. Physical Layer The Physical Layer is the lowest layer of th...
