The popularity of computers and the rapid development of technology have eliminated many computer peripherals; the connection methods of computer peripherals are also diverse, from the early PS2 interface that supports the keyboard and mouse and the 25-pin large parallel port transmission line of the old printer to the present HDMI video cable, with the update of the equipment, there will be more peripheral cables with different interfaces in the future; today I will lead you to review the standard cables of computer peripheral peripherals.
AV video cable; In the DVD era, this is a new generation of transmission cable upgraded from RF cable, which separates the transmission of sound and image for the first time; AV cables are still widely used by everyone. AV audio cable; mainly used to connect the computer to the power amplifier equipment, and input audio from the computer to the audio equipment.
The COM port cable (also known as R232) is mainly used to connect older computer peripherals; for example, printer R232 to USB: It is mainly used to convert some devices because they are too old to be supported by the computer. For example, old-fashioned printers, current computer motherboards do not support the COM interface, and the old device can continue to be used with this cable.
But when it comes to 5G, it seems that the public can only think of the advantage of faster speed, and there is no inevitable connection with smart homes. But in fact, 5G and smart home are closely related. It can be said that the real realization of smart home needs to be promoted and realized by 5G. So let me talk about the advantages of 5G first:
1. High speed, up to 10 Gbit/s, 100 times faster than the previous 4G LTE cellular network;
2. Ultra-low latency, 5G requires a minimum latency of about 1ms, while 4G is 30-70ms;
3. Super large network capacity, providing the connection capacity of millions of devices, meeting the communication of the Internet of Things;
4. The spectrum efficiency is more than 10 times higher than that of LTE;
5. With continuous wide-area coverage and high mobility, the user experience rate can reach 100Mbit/s, and movies can be watched at high speeds;
6. The flow density and connection number density are greatly improved;
7. The system is coordinated, and the level of intelligence is improved, showing the assistance of multiple users, multiple points, multiple antennas, and multiple captures.
In the 4G era, home security is limited by bandwidth resources, network tariffs, signal interference and other factors. HD surveillance always suffers from freezes or signal loss. With the advent of the 5G era, the network will have larger bandwidth, faster transmission speeds and more stable signals. The problems that plague home security will be solved. Home security will usher in the real-time high-definition era, realize mobile monitoring, and better protect the family. Security becomes a reality.
As more and more devices can be connected, the wireless connection between smart homes and smart communities, and wireless connection between smart communities and smart cities is also possible. Perhaps in the near future, people will be able to enjoy the convenience of smart life and smart travel.
