Topology
Topology defines the structure of the network of how all the
components are interconnected to each other.
Physical topology is the geometric representation of all the
nodes in a network.

Network Topology
Difference between Switch and Router
Switch:
1. Switch is a networking device.
2. Switch is a data link layer device.
3. Switch works in LAN (Local Area Network)
4. Switch works in same network.
5. Switch is an intra-network device
6. Switch use MAC (Media Access Control) address
7. Switch is an intelligent device
8. Data use as a frame format in switch.
9. Switch use CAM (Content Accessable Memory) table
10. Switch usally used in 8/16/24/48 ports
11. Switch is a multiport device.
12. Switch is a full duplex device
13. No collision occurs in switch.
14. In switch every port has its collision table.
15. Switch support advanced features like VLAN, STP, RSTP etc.
16. Switch is faster than router.
17. Switch support 10 Mbps to 1 Gbps speed.
Router:
1. Router is a networking device.
2. Router is a Network Layer device.
3. Router works for WAN (Wide Area Network)
4. Router works for communication between different network.
5. Router is an inter network device.
6. Router use IP address
7. Data use as a packet in Router.
8. Router perform routing operation
9. Router use routing table.
10. Router usally support 2/4/8 etc ports
11. Router is slower than switch.
12. Router support 10 Mbps to 100 Mbps speed
Difference between Hub and Switch
HUB:
1. Hub is a network device
2. Hub is a Physical Layer device.
3. Hub is a multiport device.
4. Signal travel in the form of bits in Hub.
5. Hub support electric signal
6. Hub is a half duplex device
7. Hub is an unintelligent device
8. Hub does not learn or store MAC address
9. Collision occurs commonly in Hub
10. Hub support only single collision dimension
11. Hub does not support Advanced features like VLAN, STP, RSTP etc.
Switch:
1. Switch is a networking device.
2. Switch is a data link layer device.
3. Switch works in LAN (Local Area Network)
4. Switch works in same network.
5. Switch is an intra-network device
6. Switch use MAC (Media Access Control) address
7. Switch is an intelligent device
8. Data use as a frame format in switch.
9. Switch use CAM (Content Accessable Memory) table
10. Switch usally used in 8/16/24/48 ports
11. Switch is a multiport device.
12. Switch is a full duplex device
13. No collision occurs in switch.
14. In switch every port has its collision table.
15. Switch support advanced features like VLAN, STP, RSTP etc.
16. Switch is faster than router.
17. Switch support 10 Mbps to 1 Gbps speed.
Network Devices
Hardware devices that are used to connect computers, printers, fax machines and other electronic devices to a network are called network devices. These devices transfer data in a fast, secure and correct way over same or different networks. Network devices may be inter-network or intra-network. Some devices are installed on the device, like NIC card or RJ45 connector, whereas some are part of the network, like router, switch, etc.
Types of network devices
· Hub
· Switch
· Router
· Bridge
· Gateway
· Modem
· Repeater
· NIC Card
