Decentralized switching prevents creating a processing bottleneck at a single point within the router. Before data can be sent out over the network interface, it must have a standard format, size, and addressing scheme. All the multiple choice question and answer mcqs have been compiled from the books of data communication and networking by the well known author behrouz a forouzan. A network refers to two or more connected computers that can share resources such as data, a printer, an internet connection, applications, or a combination of these resources. This data communication and networking network layer.
The application layer is also called as the layer 7 of the osi model. Layer 3 the network layer layer 3, the network layer of the osi model, provides an endtoend logical addressing system so that a packet of data can be routed across several layer 2 networks ethernet,token ring, frame relay, etc. Layer 2 in the darpa model is the internet layer, which maps to the network layer of the osi model. The network layer is the third level of the open systems interconnection model osi model and the layer that provides data routing paths for network communication. Doing so creates a better understanding of the network data flow. Here are the basic functionalities of the application layer. Internet protocol multiple choice questions and answers mcq pdf covers the below lists of topics.
Input port has an associated line card nic which implements physical and datalink layer functions, as well as certain network layer functions. Internet layer the internet layer is in charge of addresses, d irecting capacities. Demultiplexing was also a tcpudp feature versus application layer done by using full socket address 8 bits. Indeed, as we shall see, the protocols have been designed to operate over a large number of layer 2 protocols. Network layer internet protocol multiple choice questions. Note that network layer addresses can also be referred to as logical addresses. Application layer supports application, apps, and enduser. The center con ventions of the internet layer are ip, arp, icmp, and igmp. The internet layer is responsible for packaging, addressing, and routing the data. Data is transferred in the form of packets via logical network paths in an ordered format controlled by the network layer.
