Explain Fiber-Optics cable.
A cable with central glass tube covered with protective shield which transmit data using photons is fiber optics cable. These cables transmit data through concentrated bursts of laser beams which are carried by bundles of hair thin glass fibers. They have benefits over electronic cables in transmission speed and volume. This technology has revolutionized telecommunication applications which used electronic cables. Fiber optics cables as free from electro-magnetic interference as well as wire tapping.
In a network that contains two servers and twenty workstations, where is the best place to install an Anti-virus program? An anti-virus program must be installed on all servers
Name the factors that affect the performance of the network? a. Number of Users b. Type of transmission medium c. Hardware d. Software
It's a Hybrid device that joins the features of both bridges and routers.
Describe the main factors of switching delay No. The speed of propagation is 200,000 km/sec or 200 meters/µsec. In 10 µsec signal travels 2 km. Therefore, each switch adds equi
what is credential prompt?
Describe unbound transmission media. Unbound transmission media are the media of transmitting data without using any cables. These are not bounded by any physical geography. Ex
can we solve the problem using bounded buffer space if the propagation delay is arbitrarily large ?
A logic gate drives a load, which has a resistance of 1 kÙ and a capacitance of 20 pF. The printed circuit track connecting the gate to its load has an 40 pF capacitance to ground.
It is possible for a datagram to generate ICMP errors after it has been fragmented. For example, suppose that each of two fragments cannot be delivered. Seemingly, this would mean
