Which device is not intelligent as it sends data to all computers on a network which causes a reduction in network speed?
A
Switch
B
Router
C
Hub
D
Network Interface Card (NIC)
Explanation: 

Detailed explanation-1: -A Hub is a simple and cheap networking device that works under the physical layer of the OSI model and connects a bunch of computers in a Local Area Network(LAN). It is considered less intelligent because it does not filter data and does not know where the data is to be sent.

Detailed explanation-2: -Device Type: The hub is the least intelligent device as it simply passes a received data packet to all the devices connected to it.

Detailed explanation-3: -Essentially, a switch is a more efficient, more intelligent version of a hub. Perhaps the biggest difference between a hub and a switch is the way that it delivers data packets. Rather than blindly passing along data to all devices in a network, a switch records the addresses of the connected devices.

Detailed explanation-4: -Explanation. The correct answer is a switch. The switch is an intelligent hub that uses a MAC address to route traffic.

Detailed explanation-5: -A bridge is a programmable intelligent device that connects physically separate LAN segments into one logical LAN segment. There are four categories of bridge: transparent, source routing, encapsulating, and translating.
