Expert Solution

1) User Datagram Protocol (UDP) is a communication protocol that facilitates the exchange of messages between computing devices in a network. It is an alternative to the transmission control protocol (TCP). In a network that uses the Internet Protocol (IP), it is sometimes referred to as UDP/IP. It speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party.

Source port number

This field identifies the sender's port.

Destination port number

This field identifies the receiver's port and is required.

Length

This field specifies the length in bytes of the UDP header and UDP data.

Checksum

The checksum field may be used for error-checking of the header and data.

2) The RS-232 standard a logic high ('1') is represented by a negative voltage – anywhere from -3 to -25V – while a logic low ('0') transmits a positive voltage that can be anywhere from +3 to +25V..
