Switches, Routers, Bridges, and Hubs

Question 1

A node that broadcasts data to every computer or Ethernet based device connected to it. This Node is less sophisticated than a switch and best suited for small local area networks (LAN)
This is also a layer 1 device that connects multiple network devices and workstations

Answer 1

Hub

Question 2

This transmits data from one device to another in form of frames
Connects multiple clients to a network, more scalable, and practical
This is a layer 2 device
This sends traffic to ports based on their MAC addresses and is a network device used to connect devices

Answer 2

Switch

Question 3

This transmits data from one network to another in the form of packets
This is a layer 3 device that connects multiple networks and makes forwarding decisions based on logical network information
This helps connect to the Internet and other people’s networks and routes traffic based on destination IP addresses
A network device that connects multiple network segments together into a single network. Does not pass broadcast traffic and uses ACLs

Answer 3

Router

Question 4

Connects two LANS (local area networks)
Here packets are processed on MAC addresses (hardware address) inside the incoming packet
Analyzes MAC addresses and makes intelligent forwarding decisions based on the destination MAC in the frames.

Answer 4

Bridge

Question 5

This type of hub repeats signals with no amplification

Answer 5

Passive Hub

Question 6

This type of Hub repeats signals with amplification

Answer 6

Active Hub

Question 7

This type of hub is an active hub with enhanced features like SNMP (simple network management protocol, which allows you to actively control the hub and configure it from a distance)

Answer 7

Smart Hubs
