Match the following network topologies with their behavior in case of connection failure:

<p>Mesh = If one connection fails, the other connections will still be working. Star = The other devices will still be able to send data through the hub; there will be no access to the device which has the failed connection to the hub. Bus = All transmission stops if the failure is in the bus. If the drop-line fails, only the corresponding device cannot operate. Ring = The failed connection may disable the whole network unless it is a dual ring or there is a by-pass mechanism.</p>

Match the following types of transmission with their characteristics:

<p>Half-duplex = Only one entity can send at a time. Full-duplex = Both entities can send at the same time. Multipoint = Multiple entities can send at the same time. Point-to-point = Only two entities can send at the same time.</p>

Match the following formulas with their corresponding definitions:

<p>T = 1/f = Period (T) is the reciprocal of frequency (f). f = 1/T = Frequency (f) is the reciprocal of period (T). λ = v/f = Wavelength (λ) is the product of propagation speed (v) and frequency (f). Mesh: n (n – 1) / 2 = The formula to calculate the number of cables in a mesh network.</p>
