User Mode is used for regular task when using a CISCO router, such as to view system information, connecting to remote devices, and checking the status of the router. It also synchronizes applications on the server and client.ġ3) Differentiate User Mode from Privileged Mode The Application Layer supports the communication components of an application and provides network services to application processes that span beyond the OSI reference model specifications. Diskless workstations also use BootP in order to determine its own IP address as well as the IP address of the server PC.ġ2) What is the function of the Application Layer in networking? – DRAM stores the configuration file that is being executed.īootP is a protocol that is used to boot diskless workstations that are connected to the network. – NVRAM stores the startup configuration file. On the other hand, IGRP takes consideration many factors before it decides the best route to take, such as bandwidth, reliability, MTU and hop count.ġ0) What are the different memories used in a CISCO router?ĭifferent memories used in a CISCO router are: RIP relies on the number of hops in order to determine the best route to a network. The LLC can also provide error correction. One option is to provide flow control to the Network layer by using stop/start codes. It can provide optional services to an application developer. The LLC sublayer stands for Logical Link Control. It stores the entire frame to its buffers and performs a CRC check before deciding whether or not to forward that data frame.Ĩ ) What is the role of the LLC sublayer? What a bridge actually does is to take the large network and filter it, without changing the size of the network.ħ) Which LAN switching method is used in CISCO Catalyst 5000?ĬISCO Catalyst 5000 uses the Store-and-forward switching method.
This is especially true in big networks that do not resort to network segmentation.Ī Window refers to the number of segments that are allowed to be sent from source to destination before an acknowledgment is sent back.Ħ) Does a bridge divide a network into smaller sections? Network congestion occurs when too many users are trying to use the same bandwidth. This is a very efficient means of data transmission, instead of broadcasting it on all ports. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port. When a switch receives a signal, it creates a frame out of the bits that were from that signal. Another function of this layer is framing.ģ) What is the key advantage of using switches? The job of the Data Link layer is to check messages are sent to the right device. Routing is done by a device called routers, which are network layer devices. Routing is the process of finding a path on which data can pass from source to destination.
