A. Asynchronous frequency division multiplexing
B. Asynchronous time division multiplexing
C. Asynchronous space division multiplexing
D. Asynchronous amplitude division multiplexing
Explanation: ATM uses a constant data stream consisting of transmission cells to transmit information in a fixed division of time. The packet size remains fixed.
A. 2
B. 3
C. 4
D. 5
Explanation: The three layers are physical layer, ATM layer and application adoption layer. The physical layer corresponds to the physical layer, ATM layer corresponds to the data link layer and the AAL layer corresponds to the network layer of the OSI model.
A. Local area network
B. Wide area network
C. Campus area network
D. Networks covering any range
Explanation: ATM is a connection oriented network for cell relay which can be implemented for networks covering any area. It uses Time Division Multiplexing and supports voice, video and data communications.
A. 32 bytes
B. 48 bytes
C. 64 bytes
D. 128 bytes
Explanation: An ATM field contains a header and a payload. The header is of 5 bytes and the payload is of 48 bytes. The size of the header remains fixed.
A. Virtual circuit networks
B. Datagram networks
C. Virtual private networks
D. Virtual public networks
Explanation: ATM and frame relay are transmission modes in which information is transferred through electric circuit layer as packets. ATM has fixed packet size and frame relay has variable packet size.
A. Local coverage determination
B. Loss of cell delineation
C. Logically coded decimal
D. Local change directory
Explanation: The ATM has helped bring about the merger of computer and telecommunication networks. The ATM Forum, an organization that specifies standards for ATM implementation, has also provided a framework for network management. The subject of ATM is full of acronyms. Therefore LCD in ATM networks stands for ‘Loss of Cell Delineation’.
A. It can be established by transporting packets in the sequence in which they were transmitted by the source along the same path for a given session
B. It can be established by grouping a number of virtual circuits between two switches into a virtual path
C. . when the connection is established for long periods of time and not switched between sessions, a permanent virtual circuit (pvc) is established. advertisement
D. It can be established on a per session basis or on a permanent basis between a pair of end stations that carry large volumes of traffic
Explanation: The VP- VC can be established on a per session basis or on a permanent basis between a pair of end stations that carry large volumes of traffic. In the former ease, the circuit is established as and when needed and torn down after the session is over. This is called the switched virtual circuit (SVC). When the connection is established for long periods of time and not switched between sessions, a permanent virtual circuit (PVC) is established.
A. Service provider
B. Network manager
C. Network agent
D. Customer
Explanation: There are two markets for ATM switches using ATM technology, public and private. A public network is the network that is established by the service provider. A private network is primarily a campus network.
A. True
B. False
C.
D.
Explanation: The broadband network and the narrowband Integrated Services Digital Network (ISDN) are multimedia networks that provide integrated analog and digital services over the same network. The broadband network can transport very high data rate signals.
A. LAN
B. MAN
C. WAN
D. Pan
Explanation: The broadband network can transport very high data rate signals. It is a multimedia transportation networking. The computer network uses the facilities of the telecommunication network fur transportation over WAN. Thus Broadband network management consists of managing the WAN using ATM technology.
