We'll also cover the basics of routing, routing . So, you might run an email program and a web browser, both client 8 bits. It is calculated by doing Cyclical Redundancy Checks achieved by polynomial divisions over the entire header contents of all the three layers mentioned above. TCP and UDP ports at the transport layer are what enables our devices to Before transmitting any of the data the web browser wants to, the networking stack needs to establish a connection. Both client applications on your PC at the same time and your email and web server might both run on the same server. This layer uses various protocols depending on the applications.For example, HTTP(Hyper Text Transfer Protocol) is used by the web-servers and the web-pages.In case of OSI model, this layer is split into Session layer , Presentation Layer and Application Layer. Even so, emails end up in your email application and web pages end up in That's because the protocol most commonly used in the fourth layer, the transport layer, is known as TCP or transmission control protocol. Choose all of the frequencies that wireless networks typically operate on. Q1.
