Test: Types and Methods of Data Transmission - Question 7
How does a recipient system handle data packets that arrive out of sequence?
Detailed Solution for Test: Types and Methods of Data Transmission - Question 7
The recipient system reorganizes the packets based on their unique identifiers (packet numbers) to reconstruct the original message accurately.
Test: Types and Methods of Data Transmission - Question 8
Which error checking mechanism involves using a parity bit?
Detailed Solution for Test: Types and Methods of Data Transmission - Question 8
A parity bit is used as an error checking mechanism to verify that bits have not been inadvertently altered during transmission.
Test: Types and Methods of Data Transmission - Question 9
What happens when a USB device is connected to a computer for the first time?
Detailed Solution for Test: Types and Methods of Data Transmission - Question 9
When a USB device is connected to a computer for the first time, the computer searches for and loads a compatible driver to enable communication between the device and the system.
Test: Types and Methods of Data Transmission - Question 10
Which term describes the process of breaking down data into small pieces for transmission over the internet?
Detailed Solution for Test: Types and Methods of Data Transmission - Question 10
