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 is the difference between RJ50 and RJ45 connectors?
The main differences between RJ50 and RJ45 connectors are transmission rate, application scenarios, number of pins, line sequence, transmission distance, and anti-interference ability.
Transmission rate and application scenarios:
The transmission rate of the RJ50 interface is low, and it can usually only transmit voice and low-speed data signals. It is mainly used for telephone lines and low-speed network devices such as modems and routers.
The transmission rate of the RJ45 interface is high, and it can transmit high-speed data signals. It is mainly used for Ethernet and high-speed network devices such as computers, switches and routers.
Number of pins and line sequence:
The RJ50 interface has 4 pins, and the line sequence is 1-2-3-4.
The RJ45 interface has 8 pins, and the line sequence is 1-2-3-4-5-6-7-8.
Transmission distance and anti-interference ability:
The transmission distance of the RJ50 interface is short, and it can usually only be used within a few dozen meters. It h -
4. What is the difference between modular cable and non-modular cable?
The main difference between modular cable and non-modular cable is the detachability of the cable and the design structure of the power supply.
Modular cable, also known as modular power supply, allows the cable to be disassembled and reconfigured according to needs, providing greater flexibility and convenience. This design allows the cable to be matched according to personal needs, reducing the storage space of the cable and making the inside of the computer case neater. In addition, the cable of the modular power supply can be upgraded and replaced, further increasing the flexibility of use. However, the number of cables of the modular power supply is large and the quality is unstable, so it is necessary to purchase a good quality power supply, which increases the cost consideration.
Non-modular cables, that is, non-modular power supplies, all of whose wires and cables are fixed and cannot be removed, which may cause cross-wiring of cables, making the entire computer look messy. T
