Explanation: datagram is connection-less and virtual circuits are connection oriented.
Explanation: the protocols using udp are echo, time, domain name server, network file system etc.
Explanation: some of the protocols using tcp are http, telnet, file transfer protocol, simple mail transfer protocol etc.
Explanation: g series tells about level transmission, modulation and framing.
Explanation: q series tells about signalling.
Explanation: piconet is the basic unit of a bluetooth system having a master node and upto seven active slave nodes. a collection of piconets is called scatternet and a slave node of a piconet may act as a master in a piconet that is part of the scatternet.
Explanation: the equation to find the end to end delay when no. of bits, transmission rate and no. of routers is given by (n*l)/r. the total end to end delay, that is, nodal delay is the sum of all, the processing delay, queuing delay, transmission delay and propagation delay.
Explanation: packet switching and circuit switching are two different types of switching methods used to connect the multiple communicating devices with one another.
Explanation: in circuit switching, a physical path between the sender and receiver is established. this path is maintained until the connection is needed. circuit switching is implemented in the physical layer and is used in telephonic systems.
Explanation: circuit switching is connection oriented and is always implemented in the physical layer. once a path is set, all transmission occurs through the same path. it is used since the early times in telephonic systems.
