1. What is the purpose of modular jacks?
The purpose of modular jacks is to connect devices to the network. Modular jacks are designed to provide a flexible and scalable solution to adapt to changing and diverse network needs. They usually have multiple free slots, allowing users to choose modules of different numbers, speeds and interface types to install according to specific needs, thus achieving a high degree of customizability and scalability.

2. What is a jack connector?
A jack connector is an electronic device that provides a hole or other connection method that allows a compatible plug to be connected to the jack. In the computer field, jacks are usually used to describe audio jacks, which are used to connect audio devices such as headphones or microphones. Jack connectors are used with plugs to connect and disconnect circuits through their engagement and separation. This connection method is very common in electronic devices because it provides a simple and reliable way to connect and disconnect wires or cables, thereby connecting or disconnecting circuits between electronic devices.

3. What are the different types of RJ45 modular jacks?
There are two main types of RJ45 modular jacks, namely DTE (data terminal equipment) type and DCE (digital communication equipment) type.
The difference between these two types lies in the way they are connected to different devices.
The DTE type is mainly used in Ethernet network cards, routers and other devices. When two DTE type devices use RJ45 interface connection for communication, they must be connected using a crossover cable. This is because the data sending and receiving pins of the DTE type interface cannot perform normal data communication if they are not cross-connected.
The DCE type is usually used in devices such as switches. When connected to a DTE type device, the DCE type device can automatically negotiate with the other party. At this time, a straight-through line or a parallel line can be used for connection, depending on the automatic negotiation capability of the device. -
4. What is the correct term for RJ45 modular plug?
The correct term for RJ45 modular plug is RJ45 plug.
RJ45 plug, also known as crystal head, is a commonly used connector in network cabling system. It consists of 8 contacts and is divided into two types: shielded and unshielded.
