Network Protocols and Error Detection Quiz

What is the simplest method of error detection mentioned in the text?

• Checksum

• Echo checks

• Parity bits

• Automatic repeat requests

In an even parity system, what should be the total number of 1-bits in each packet?

• Odd

• Even

• Prime

• Zero

What is a network protocol?

• A method to encrypt data

• A set of standards and rules for communication over a network

• A type of error detection

• A way to compress data

What does a packet number indicate?

• The size of the packet

• The position of the packet in the sequence of data being transmitted

• The type of data in the packet

• The speed of data transmission

What is a parity bit?

• A bit used to store data

• A bit used to detect errors in data transmission

• A bit used to increase data speed

• A bit used to compress data

In an even parity system, what indicates a successful data transmission?

• Total number of 1-bits is odd

• Total number of 1-bits is even

• Total number of 0-bits is odd

• Total number of 0-bits is even

In an odd parity system, what indicates a corrupted data transmission?

• Total number of 1-bits is odd

• Total number of 1-bits is even

• Total number of 0-bits is odd

• Total number of 0-bits is even

What is a checksum used for in data transmission?

• To encrypt data

• To determine the integrity of transmitted data

• To compress data

• To increase data speed

How is a simple checksum calculated for data?

• By multiplying all the bytes in the data

• By subtracting all the bytes in the data

• By summing all the bytes in the data and calculating the result modulus 256

• By dividing all the bytes in the data

What happens if the checksum value of the received data matches the sent checksum value?

• An error has occurred

• The data was transmitted correctly

• The data needs to be sent again

• The data is corrupted
