When is a wired connection preferred to a wireless connection by an end-user device?

a. When the end-user device is within range of a wireless signal

b. When the end-user device will run an application that requires a dedicated connection to the network

c. When the end-user device only has a WLAN NIC

d. When the end-user device will run an application that is delay tolerant

Option (b) When the end-user device will run an application that requires a dedicated connection to the network

Explanation:

Option (b) is the correct option. When the user device requires a highly dedicated network environment to itself to run a web application that requires large download and upload speeds, bandwidth requirements then it prefers a wired connection than a wireless connection. If the wireless signal is within the reach, then it advisable to go for a wireless connection than a wired connection. A wired connection requires other hardware equipments like a internet connection cable etc. which is not required in case of wireless connection. So, option (a) is wrong option. WLAN NIC is a wireless interface network controller that connects to a wireless radio based network than a wired network. So, option (c) is wrong option. Delay torrent network is designed to operate where continuous network connectivity is not available like extreme terrestrial spaces, space communications, inter planetary communications etc. So, option (d) is wrong option.
