Introduction

In today's digital era, network products have become an indispensable part of our daily lives and work. Among network products, network card technology plays a pivotal role. Whether it's in home, school, or corporate network connections, network cards are the key to information transfer and interaction. This article aims to comprehensively analyze the network card technology in network products so that we can better understand its importance. II. Overview of Network Card Technology A network card, also known as a network interface card, is a bridge between a computer and a network. It is responsible for converting computer data into a format that can be transmitted on the network and receiving data transmitted on the network. Network card technology mainly involves hardware and software aspects, including physical layer, data link layer, and network layer. III. Hardware Composition of Network Card Technology The hardware part of the network card mainly consists of the following parts: interface, main processor, memory, MAC address chip, and related network drivers. The interface is responsible for connecting the computer to other network devices; the main processor is the "brain" of the network card, responsible for processing operations such as data transmission and reception; memory is used to store temporary data and instructions; and the MAC address chip is used to store the unique identifier code of the device for network device recognition. IV. Software Implementation of Network Card Technology In addition to the hardware part, network card technology requires software cooperation to achieve its functions. These software include drivers, network protocol stacks, etc. The driver is a bridge connecting hardware and software, which enables the operating system to recognize and control the network card; while the network protocol stack is responsible for handling operations such as network data transmission and reception. V. Types of Network Card Technology According to different classification standards, network cards can be divided into wired network cards and wireless network cards. Wired network cards are mainly used for wired network connections, with advantages such as high transmission speed and stability; while wireless network cards provide more flexible network connection methods that can achieve network connectivity without the need for wiring. Additionally, according to their functions and performance, they can be divided into ordinary network cards and high-speed network cards. VI. Application and Development of Network Card Technology With the popularity of the Internet and the continuous development of technology, network card technology is also continuously progressing. From the initial Ethernet to the current 5G network, there have been significant improvements in transmission speed
