You may need to troubleshoot different aspects of a network, so its important that you know how everything fits together. quickest path for reaching network B, where Computer 2 resides. That's a whole lot of possibilities. Select examples of these new layers below. Ethernet frame was successfully transmitted to the router. receive it and, therefore, performs a checksum calculation. We'll cover everything from the fundamentals of modern networking technologies and protocols to an overview of the cloud to practical applications and network troubleshooting. Great course. It's this layer that allows different networks to communicate with each other through devices known as routers. TCP 20/21 FTP is one of the most commonly . inspects it and observes the destination MAC address, which is the router another checksum is calculated and a new IP datagram is created in the They uniquely identify an adapter on a LAN. Q2. That's because the protocol most commonly used in the fourth layer, the transport layer, is known as TCP or transmission control protocol. required some additional Windows machines. We'll learn about the IP addressing scheme and how subnetting works. Taking in consideration that computer 1 is sending a request to a web server on computer 2, listening on port 80, and the source port on computer 1 is 5000, which of the following contains the correct information for the first TCP segment of data? What ordering of TCP flags makes up the Three-way Handshake? answering the request across the network. So, it can be doing many different things. 3418). The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. to ensure the data integrity of all of the combined elements up to this point, When receiving data,network layeris used to determine if the packet received by the host contains the hosts IP address. An example of something that operates at the application layer is: Q3. It's the network layer that helps get the data between these two locations. Later on in this lesson when we introduce ARP or address resolution protocol, you'll see that the way that nodes learn about each other's physical addressing isn't translatable to anything besides a single network segment anyway. Then, the TCP segment is inserted as the data payload of the IP datagram.
