Answer:
A method in python is somewhat similarto a function, except it is associated with object/classes. Methods in python are very similar to functions except for two major differences. The method is implicitly used for an object for which it is called. The method is accessible to data that is contained within the class.
Answer:
It's also called the modulo operator.
Answer:
It will not necessary that bob will provide chunks to Alice.
Explanation:
Alice has four neighbors of Bob so he will send message to her, but this might not occur if Alice provides chunks to Bob.
Overlay is the network that build at the top of other network.It is a telecommunication network that supported by its own infrastructure.
It encapsulates one packet inside an other packet.
It is a method of creating layers of network that can be used to run multiple virtualized layers on the top pf other network.
It provides new security benefits.
Does Overlay include Routers
Overlay is a file sharing system in which nodes participating and create logical links between them.So overlay network does not include routers.
Edge in overlay
It is a logical network in which nodes are connected using virtual or logical links.
Answer:
Transport layer:
- data packets are segment to smaller chunks.
- gives sequence number to segment.
- identifies the source and destination port number.
- initiates data transmission between nodes.
- rearrange and identifies the application, the transmitted data is meant for.
Explanation:
The transport layer is the fourth layer in the OSI network model. Protocols like TCP and UDP are found in this layer. It segment data packets and for a connection oriented protocol like TCP, it creates an established session between source and destination host (the session layer can also do this, but it is more defined in the transport layer).
The network and data-link layer can also transmit data packets.
