Answer:

"is-a" relationship is used to indicate that a derived class belongs to the family of base class.

Explanation:

IS-A relationship based on Inheritance, which can be of two types Class Inheritance or Interface Inheritance.

"is-a" relationship is used to indicate that a derived class belongs to the family of base class. For example vehicle is a class which belongs to car base class.

Any derived class that extends base class have " is-a " relation ship with base class

Any class that implement an interface also has  " is-a " relation ship" with the interface

Answer: star topology.

Explanation:

The layout of the way how the computers in a netword are interconnected is called network tipology.

Some types of network topologies are:

1) Point-to-point tipology: all the computers are connected to each other directly (computer-to-computer, in pairs, this is a direct link between each two computers).

2) Bus topology: all the nodes (computers or server) are connectect to a maing cable.

3) Star topology: all the computers are connected to a central computer or server which is called central hub. This is the layout described in the question.

4) Ring topology: the computers are connectec in a circular path; each computer is connected to the next computer.

5) Mesh: every computer is connected to every other computer.

A switch that is configured to use the Spanning Tree Protocol will place a port in ____________ mode if sending traffic to it ma
Rashid [163]

Answer:

Blocking Mode    

Explanation:

Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called loops.

When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.

This affects the performance of the network as the result of broadcast packets flooding.

STP puts one port of the switch to forwarding mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to blocking mode and the one port that is left after this is placed in forward mode.

Spanning Tree Algorithm is used by STP to determine the optimal path  of switch to the network.

Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.

This information helps STP to eliminate the redundant paths.

So this is how STP allows only one active path to the destination while blocking all other paths to avoid switching loop.

The angles of a quadrilateral are in the ratio 1:2:3:4 what is the largest angle​
zheka24 [161]

Answer:

144°

Explanation:

The sum of the measures of interior angles of a quadrilateral is 360°

The ratio of angle measures is 1:2:3:4

Total ratio = 1+2+3+4=10

The angles will be :

1/10 * 360°= 36°

2/10*360°=72°

3/10*360°=108°

4/10*360°=144°

The largest angle is 144°
