Answer:

Mail bomb is the correct answer.

Explanation:

In the following statement, A mail bomb is the type of attack on e-mail of the particular person by which the attacker transfers large quantities of e-mail to the target computer in the expectation of flooding the target with so much meaningless e-mail that legitimate e-mail is not accessible. So, that's why the following answer is correct.

Sudden changes in _____ especially in high humidity conditions may cause condensation inside the camera and spoil it

Diano4ka-milaya [45]

Sudden changes in temperature especially in high humidity conditions may cause condensation inside the camera and spoil it.

<u>Explanation:</u>

When the temperature changes suddenly, it will affect the camera lens through condensation. Condensation when it is caused only for few rounds, the camera will not be damages. But, when the process of condensation continues top exists it will definitely ruin and damage the camera.

Condensation affects the internal functionalities of a camera. When a camera is brought from an environments where it is cold and dry, it will be affected by condensation during the period of summer. This is because it will be hot and this causes sudden change ion the temperature. Thus, it the changes in the environment temperature that causes damages to camera.

How does the CSMA/CD protocol resolve when two network adapters on the same network transmit at the same time?

KengaRu [80]

Answer:

If two network adapters on the same network transmit at the same time, one of the adapters would stop transmitting until the second adapter has finished transmitting before retransmission

Explanation:

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol used to prevent data collision. CSMA/CD detects collisions by sensing transmissions from other nodes. If a collision is detected, the node stops transmitting, sends a jam signal, and then waits for some time until the channel is idle before retransmission.

If two nodes on the network start transmitting at the same time, the nodes will detect the collision and take the appropriate action.

If two network adapters on the same network transmit at the same time, one of the adapters would stop transmitting until the second adapter has finished transmitting before retransmission

Explain how chord works. To increasing the fault tolerance in chord, each node maintains a successor list (finger table) instead

andrew11 [14]

Answer:

Chord is a set of rules for a peer-to-peer distributed hash table it collects key-value sets by allotting keys to several computers (known as "nodes"); a node will collect the values for all the keys for which that is reliable. Chord defines how keys are allocated to the nodes, and how a node can determine the value for a distributed key by first locating the node liable for such key.

Explanation:

A chord is a peer-to-peer lookup service. It Resolves the difficulty of establishing a data item in a combination of shared nodes, considering various node arrivals and removals The most crucial operation in most peer-to-peer method is the efficient position of data objects.

It is able of supporting only one operation i.e. given a key, it maps the key on a link.

Algorithm:

Algorithm shows working of the chord:

// x is a node used to find successor of id

x.find_successor(id)

if (id (x; successor])

return successor;

else

// query is being delivered around the circle

entrance successor.find_successor(id);
