- 2. Definition of networking devices Network devices, or networking hardware, are physical devices that are required for communication and interaction between hardware on a computer network.
- 3. Types of networking devices Here is the common network device list: 1. Hub 2. Repeater 3. Bridge 4. Switch 5. Access-Point 6. Router 7. Network Interface Card 8. Multi-layer switch 9. Firewall 10. Intrusion Detection System 11. Intrusion Prevention System 12. server
- 4. 1. Hub Properties of Hub devices : hub is the simplest in the family of network connecting devices because it connects LAN Hub operate physical layer in OSI. Hub have one collision domain Hub have one broadcast domain Hubs do not perform packet filtering or addressing functions There are two types of hubs: simple and multiple port
- 5. 2. Repeater Properties of repeater A repeater is an electronic device that amplifies the signal it receives. When the received signal
- 6. 3. bridge Properties of bridge: . The basic role of bridges in network architecture is storing and forwarding frames between the different segments that the bridge connects. Bridge operate in data-link layer in OSI.
- 7. 4. Switch Properties of switch Switches generally have a more intelligent role than hubs. Switch operate data-link layer in OSI. Switch more than interfaces than hub device Switch has many collision domains (each port have one collision domain ). Switch has one broadcast domain. Switch perform frame filtering using mac-address table. There are two types of switch: normal switch and layer 3 switch
- 8. 5. Access-Point Properties of access-Point AP generally connected wireless LAN. AP operate data-link layer in OSI model. To connect to a wireless AP, you need a service set identifier (SSID) name.
- 9. 6. Router Properties of router Router generally connect two or more networks . Router operate network layer in OSI. Routers are your first line of defense. Router perform packet filtering using IP routing table
- 10. 7. Network Interface Card Properties of NIC A network interface controller is a computer hardware component that connects a computer to a computer network.
- 11. 8. Multi layer switch Properties Of multi layer switch: A multilayer switch is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers (layer three like router).
- 12. 9. firewall Properties of firewall : In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet.
- 13. 10. Intrusion Detection System Properties of IDS : An intrusion detection system is a device or software application that monitors a network or systems for malicious activity or policy violations.
- 14. 11. Intrusion prevention System Properties of IPS : An Intrusion Prevention System is a device or software application that monitors and control a network or systems for malicious activity or policy violations.
