Match the LIST-I with LIST-II

	LIST-I (Network Devices)		LIST-II (Functions)
A.	Bridge	l.	Device that can receive the data, analyse it and transmit it to other networks
B.	Router	ll.	Set of rules that decides how computers and other devices connect with each other through cables in a LAN
C.	Gateway	lll.	Serves as the entry and exit point of a network
D.	Ethernet	lV.	Device that connects one LAN to another LAN that uses the same protocol

Choose the correct answer from the options given below:

The correct answer is - A - IV, B - I, C - III, D - II

Key Points

• Bridge - IV
  • A Bridge is a device that connects one LAN to another LAN that uses the same protocol.
  • It operates at the Data Link Layer (Layer 2) of the OSI model.
• Router - I
  • A Router is a device that can receive the data, analyze it, and transmit it to other networks.
  • It operates at the Network Layer (Layer 3) of the OSI model.
• Gateway - III
  • A Gateway serves as the entry and exit point of a network.
  • It can operate at any layer of the OSI model, often at multiple layers simultaneously.
• Ethernet - II
  • Ethernet refers to a set of rules that decides how computers and other devices connect with each other through cables in a LAN.
  • It is a widely used standard in local area networks (LANs).

Additional Information

• Network Devices
  • Switch
    • A network switch operates at the Data Link Layer (Layer 2) and sometimes at the Network Layer (Layer 3).
    • It is used to connect devices within a network, using MAC addresses to forward data to the correct destination.
  • Modem
    • A Modem (Modulator-Demodulator) is a device that converts digital data from a computer into analog signals for transmission over telephone lines and vice versa.
    • It enables internet connectivity through ISP services.
  • Access Point
    • An Access Point is a device that allows wireless devices to connect to a wired network using Wi-Fi.
    • It acts as a bridge between wireless and wired networks.
