Network nodes are divided into the following main categories based on their functions and purposes: Client nodes obtain resources and services Server nodes provide resources and services Router nodes forward packets Switch nodes forward packets Gateway nodes connect different networks Firewall nodes monitor and Filtering Packets Load Balancer Node Optimization Performance

Classification of Network Nodes

Network nodes are those connected to the network devices that play a vital role in network communications. Network nodes can be divided into the following main categories based on their functions and purposes:

1. Client nodes

• Communicate with the server to obtain resources and services .
• Typical examples: PC, laptop, smartphone.

2. Server node

• Provides resources and services to client nodes, such as file storage, application access, and database management.
• Typical examples: file server, database server, Web server.

3. Router node

• forwards data packets between different networks.
• Helps packets find the most efficient path from the source node to the destination node.
• Typical examples: home routers, enterprise routers.

4. The switch node

• forwards data packets within the same network.
• Allows network devices to communicate with each other without having to be relayed through a router.
• Typical examples: Ethernet switches, fiber optic switches.

5. Gateway nodes

• Connect different types of networks, such as local area networks (LAN) and wide area networks (WAN).
• Translate and forward packets to ensure communication between different networks.
• Typical examples: network access point, modem.

6. Firewall node

• Monitors and filters data packets in and out of the network.
• Block unauthorized access and malware attacks.
• Typical examples: hardware firewall, software firewall.

7. Load Balancer Nodes

• Optimize the performance of websites and applications by spreading out incoming traffic.
• Prevent single server from being overloaded and improve system availability and responsiveness.
• Typical examples: hardware load balancer, software load balancer.
