Computer Networking A 4 KHz noiseless channel with one sample every 125 per sec, is used to transmit digital signals. Find the bit rate (bits per second) that are sent, if CCITT 2.048 Mbps encoding is used. 64 Kbps 500 Kbps None of these 8 Kbps 32 Kbps 64 Kbps 500 Kbps None of these 8 Kbps 32 Kbps ANSWER DOWNLOAD EXAMIANS APP
Computer Networking The Token-Ring architecture was developed for a more efficient way to determine who should be transmitting at any one time. With Ethernet, collisions may take place, causing the transmitting computers to have to retransmit their data. The use of token guarantees that only one computer can transmit at a time. What happens as the network increases in size? Choose the best answer The network becomes more efficient The network becomes less efficient The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device An additional token is added for every 1,000 nodes The network becomes more efficient The network becomes less efficient The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device An additional token is added for every 1,000 nodes ANSWER DOWNLOAD EXAMIANS APP

Computer Networking Which of the following is true when describing a multicast address? Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address. Packets addressed to a unicast address are delivered to a single interface. Identifies multiple interfaces and is only delivered to one address. This address can also be called one-to-one-of-many. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
