In the digital age, network technology is constantly evolving, and to meet the increasing demand for data transmission, various network devices and technologies have emerged as critical. Among them, network cards and hubs, as important components of the network infrastructure, provide indispensable help for improving network speed through their unique performance and functions. **Network Card**: The network card, also known as a network adapter or network interface card (NIC), is one of the core devices connecting a computer to the network. Its main function is to connect the computer to the network and transmit and receive data packets through data link layer and network layer protocols. 1. Performance Improvement: The performance of the network card directly affects the entire network's transmission speed. High-bandwidth network cards can handle more data traffic and reduce data transmission delay. 2. Compatibility: The compatibility of the network card is also a key factor in improving network speed. Good compatibility with network devices ensures stable and efficient data transmission. 3. Anti-interference Capability: The anti-interference capability of the network card is also an important manifestation of its performance. Excellent anti-interference design can ensure the accuracy of data transmission and reduce transmission errors caused by electromagnetic interference. **Hub**: The hub is a network device used to connect multiple devices. It can receive signals from one device and replicate them to all other connected devices. Hubs play an important role in improving network connectivity and speed.

1. Expandability: Hubs can easily connect multiple devices, thereby expanding the coverage and capacity of the network. Multi-port hubs can connect more devices and improve network connectivity. 2. Signal Enhancement: Hubs can enhance signal strength, ensuring the stability and reliability of data transmission. This is particularly important for long-distance transmission, reducing transmission errors caused by signal attenuation. 3. Data Shunting: Hubs achieve parallel processing of data by shunting data to multiple ports, thereby improving overall network speed. In practical applications, the combined use of network cards and hubs can further improve network speed. By connecting computers to the network through high-performance network cards and connecting multiple devices together through hubs, an efficient and stable network system can be formed, which not only improves data transmission speed but also ensures network connectivity and stability.
