CIRCUIT SWITCHING AND PACKET SWITCHING 

A dynamic IP address is a different randomly allocated IP address you get every time join a server.

A static IP address is the same IP address you get every time you join a server. 

What kind of methods are data packets going to be used to be sent from one node to another? 

• circuit switching
• packet switching

What is the difference between circuit switching and packet switching?  

Circuit Switching:

• In circuit switching, each data unit is aware of the entire path address, which is provided by the source.
• This method involves the data packets following one after another along the same route to the destination.
• However, this can lead to congestion and delays due to the time taken for each packet to follow the same path.

Packet Switching:

• Conversely, in packet switching, each data unit only knows the final destination address. The intermediate path is determined by routers.
• Here, data is processed at all intermediate nodes, including the source system.
• Individual packets may travel through different routes to reach the same destination.
• This method reduces congestion and minimizes crosstalk, although data can become corrupted during transmission.

Packet Header Contents in Packet Switching:

• The header of each packet includes:
  • The Internet Protocol (IP) address it is heading to.
  • The IP address it has come from.
  • The sequence number of the packet.
  • The total number of packets involved in the communication.
