Point-to-Point Physical Connection

A point-to-point physical connection refers to a direct link between two or more computers without any intermediate network devices. In this type of connection, data is transmitted directly between the sender and the recipient without being relayed through any other device.

Switch Methods

Switching methods are used to establish communication between multiple devices in a network. The three main types of switching methods are message switching, packet switching, and circuit switching.

a) Message Switching

Message switching is a method of data transmission where the entire message is sent to the destination node in one go. In this method, the entire message is stored in the memory of each intermediate node before it is forwarded to the next node. The message is sent only when the entire message has been received and stored in the destination node.

Message switching does not create a point-to-point physical connection between two or more computers as it involves multiple intermediate nodes for message forwarding.

b) Packet Switching

Packet switching is a method of data transmission where data is divided into small packets and sent to the destination node. Each packet contains a header with routing information that is used to determine the next hop for the packet. In this method, packets are sent independently of each other and may take different routes to reach the destination node.

Packet switching does not create a point-to-point physical connection between two or more computers as packets may be relayed through multiple intermediate nodes before reaching the destination node.

c) Circuit Switching

Circuit switching is a method of data transmission where a dedicated physical connection is established between two or more computers for the duration of the communication. In this method, a circuit is established between the sender and the recipient before any data is transmitted.

Circuit switching creates a point-to-point physical connection between two or more computers as a dedicated physical connection is established for the communication.

Conclusion

The correct answer is option 'A' - Message switching does not create a point-to-point physical connection between two or more computers. Circuit switching creates a point-to-point physical connection between two or more computers.
