1. 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.

2. 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 -
3. 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 -
4. What is the difference between plugs and connector jacks?
Plugs, connectors, jacks and ports are different concepts, each of which has its own specific functions and uses in electronic equipment and electrical systems.
A plug is a physical or logical part used to plug into a jack or port, a connector is a broader connection solution that includes plugs and jacks, while a jack is the part that provides an interface, and a port is a specific area on a device for receiving a plug.
A plug generally refers to a physical connection part that can be inserted into a socket or other port for connecting power or transmitting data. Plugs are designed to fit with specific jacks or ports so that current or data can be transmitted through them. For example, a power plug is used to connect to a power socket, while a network plug is used to connect to a network port.
Connectors are a broader concept that includes plugs, jacks, and the connecting parts between them. Connectors are used to transfer current or signals between two active devices. They can b
