Essential Network Accessories for Home Network Upgrade: Purchasing Skills for Network Components With the development of technology, home networks have become an essential part of our daily lives. To ensure a stable, high-speed, and secure home network, the selection of network components has become crucial. This article will introduce the essential network components for home network upgrades and their purchasing skills. First, network cables are the foundation of network connections, crucial for home network upgrades. When purchasing network cables, consider the following aspects:

1. Type: Common types of network cables include Cat5e, Cat6, and Cat7 cables. If high-speed data transmission is required, it is recommended to choose Cat6 or higher.

2. Quality: Select high-quality network cables to ensure stable and long-lasting signal transmission. 3. Length: Choose an appropriate length of network cable based on actual needs, avoiding过长 or 过短 (excessive or insufficient length). Second, routers are core devices in a home network, responsible for distributing network signals to various terminals. When purchasing a router, pay attention to the following points: 1. Signal coverage: Choose a router with a wide signal coverage and strong wall penetration ability to meet the network needs in every corner of the home. 2. Wireless standard: The mainstream wireless standards on the market currently include 802.11n, 802.11ac, and 802.11ax, etc. Choose an appropriate wireless standard based on your needs. 3. Performance: Pay attention to the performance parameters such as the processor and memory of the router to ensure high-speed and stable network transmission. Third, switches are used to expand network interfaces, allowing multiple devices to access the network simultaneously. When purchasing a switch, consider the following points: 1. Number of interfaces: Choose a switch with an appropriate number of interfaces based on actual needs. 2. Transmission rate: Select a switch with a high transmission rate to meet the demand for high-speed data transmission. 3. Brand and quality: Choose a well-known brand and high-quality switch to ensure network stability and reliability. In addition to the above three main network components, it is also necessary to pay attention to the selection of other accessories such as network sockets and RJ45 connectors for network cables, as their quality and installation method can also affect network stability and transmission speed.
