This is accomplished by the LLC Service Access Points for the services residing on network computers. Bandwidth is the measure of the capacity of a network medium to carry data. It is the amount of data that can move between two points on the network over a specific period of time, typically one second. SC-SC patch cords are used with multimode fiber cables. C. The logical topology is always the same as the physical topology. It accepts Layer 3 packets and decides the path by which to forward a frame to a host on a remote network.
They must be changed when an Ethernet device is added or moved within the network. They increase the speed at which the data can travel. From year to year, Cisco has updated many versions with difference questions. We recommend you to go thought all version if you are not clear. While you take online test with netacad.com, You may get random questions from all version. Each version have 1 to 10 different questions or more.
An encoding technique converts a stream of data bits in a predefined code that can be recognized by both the transmitter and the receiver. Using predefined patterns helps to differentiate data bits from control bits and provide better media error detection. Physical topologies are concerned with how a network transfers frames.
Which logical address is used for delivery of data to a remote network? The destination IP address is used for end-to-end delivery of data to a remote network. The destination MAC address is used for delivery on a local network.
The trailer in a data-link frame contains error detection information that is pertinent to the frame included in the FCS field. End devices connect to a central intermediate device, which in turn connects to other central intermediate devices. The three areas of concern for wireless networks focus on the size of the coverage area, any nearby interference, jeenyus snowboarding and providing network security. Extensive cabling is not a concern for wireless networks, as a wireless network will require minimal cabling for providing wireless access to hosts. Mobility options are not a component of the areas of concern for wireless networks. Copper cabling is usually cheaper and easier to install than fiber optic cabling.
