Answer:

Message

Explanation:

  • The Application layer creates a message. The Application layer passes the message to the Presentation layer.
  • The Presentation layer encapsulates the message by adding information to it. Information is usually added only at the beginning of the message (called a header); however, some layers also add material at the end of the message (called a footer)
  • The process of passing the message down and adding layer-specific information continues until the message reaches the Physical layer.
  • At the Physical layer, the message is converted into electrical impulses that represent bits and is transmitted over the physical connection.  
  • The receiving computer captures the bits from the physical connection and re-creates the message in the Physical layer.  
  • The Physical layer converts the message from bits into a Data Link frame and sends the message up to the Data Link layer.
  • The Data Link layer strips its information and sends the message up to the Network layer.
  • This process of deencapsulation is performed until the message reaches the Application layer.
  • When the message reaches the Application layer, the data in the message is sent to the intended software recipient.

Two communicating devices are using a single-bit even parity check for error detection. The transmitter sends the byte 10101010
icang [17]

Answer:

The receiver will not detect the error.

Explanation:

The byte sent by transmitter: 10101010

The byte received by receiver due to channel noise: 10011010

If you see the bold part of the both sent and received bytes you can see that the number of bits changed is 2.

The two communicating devices are using a single-bit even parity check. Here there are two changed bits so this error will not be detected as this single bit even parity check scheme has a limit and it detects the error when the value of changed bit is odd but here it is even.

This parity scheme basically works well with the odd number of bit errors.
