Which of the following best describes "interference" in the context of data transmission?
When a device sends data faster than usual
When something disrupts or affects the signal traveling between devices
When data is stored in a secure location
When a device is turned off during transmission
Which of the following is an example of interference affecting wireless signals?
Using a wired mouse with a computer
Hearing static while listening to music on Bluetooth headphones when other devices are transmitting signals
Charging your phone overnight
Downloading files from the internet
How can physical barriers, such as walls and large objects, affect Wi-Fi signals?
They can speed up the signal
They can block the Wi-Fi signal between your phone and the router
They can make the signal more secure
They can increase the data transmission rate
What is the main purpose of acknowledgments (ACKs) in data transmission protocols?
To encrypt the data being sent
To signal that the packets have been received successfully and correctly
To increase the speed of data transfer
To compress the data before sending
What happens if the source does not receive the needed ACK within a set time?
The source deletes the packet
The source retransmits the packet, assuming it was lost or corrupted
The source ignores the missing packet
The source sends a warning message to the user
Retransmissions are important in data communication because:
They help ensure that lost or corrupted data packets are sent again, increasing the reliability of data transmission.
They are only used for wireless networks.
They are used to encrypt data.
They make the network slower on purpose.
A student is experiencing slow internet because their Wi-Fi signal is weak in their room. Based on your understanding, what could be a possible reason for this?
The internet provider is down
Physical barriers like walls are blocking the Wi-Fi signal
The computer is too old
The website is not working
If a data packet is lost during transmission and no ACK is received, what is the protocol’s next step?
Ignore the lost packet
Retransmit the packet
Send a virus alert
Change the data format
