What is a PC Adapter 15 and what is a PC Adapter

Adapter. Any hardware device that can communicate between physically disparate systems. The term often refers to a peripheral card inserted into a computer that provides an interface from the computer bus to another medium, such as a hard disk or network.

- The dividing line of all evils ---

The following is purely a personal opinion (see Comments).

Let's look at something

I think PC adapter is just a general term for a variety of devices that serve different purposes but serve computers.

understand？

It's okay if you don't understand.

I don't understand it myself ...

Go on... Things like Bluetooth, infrared, power supply, and network adapter (and so on) should all fall under the category of PC adapters

You should understand that.

Then talk about what they're used for.

In fact, we can tell from their names that they are pulling

For example, a Bluetooth adapter means that a Bluetooth device is installed in the computer (of course, you have to get a driver), and then you can receive and send data from to a device (such as a mobile phone) that also has Bluetooth function

The infrared, network adapter and Bluetooth are similar.

A network adapter is actually a network card, so you may know better! Then I won't explain much about Ra

Finally, let's talk about the power adapter, its function ms is different from the various adapters I mentioned above for transmitting data, it is said to convert xx electricity to xx electricity? And then there is the one that protects the machine (it feels like a transformer =. =）

- The dividing line of all evils ---

That's all for my personal opinion

But as you can see, I used a lot of roughly pulling, ms-pulling, like pulling, that is, it's all my own understanding, but I think the adapter "should" be like that

Of course, I'm not authoritative, you can experience it yourself, and if you understand, choose my answer as the best If you don't understand, you can also listen to other people's opinions -

The adapter is just a name, there can be many kinds, such as a power adapter for a notebook, a mini memory card also has a conversion adapter, etc., which one are you asking?

The computer adapter is the power source of the computer's work, and it is a high-quality switching power supply.

Power adapter, also known as external power supply, is a power supply voltage conversion device for portable electronic devices and electronic appliances.

Its function is to convert the 220 volt high voltage at home into a stable low voltage of about 5 volts to 20 volts that these electronic products can work, so that they can work normally, generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components, and its working principle is converted from AC input to DC output; According to the connection method, it can be divided into wall adapter and desktop adapter.

According to its output type, it can be divided into AC output type and DC output type; According to the connection method, it can be divided into wall type and desktop type.

Precautions when using a computer adapter

1. When using the laptop in a high temperature environment, the power adapter should be placed in a ventilated place away from direct sunlight; Do not place the power adapter near the heat vent of the laptop, otherwise not only will the heat of the power adapter not be dissipated, but also some of the heat will be absorbed.

2. In the hot summer, we can put the adapter on the side to increase the contact area between the adapter and the air, so that the heat of the adapter can be better dissipated. For better heat dissipation, we can also insert a narrow block of plastic or lead or metal between the adapter and the table to increase the air convection speed around the adapter and speed up the heat dissipation of the adapter.

3. When the power adapter emits large working noise or even smoke, it is often damaged or faulty, and it should be stopped immediately, and it can be put into use again after overhaul by a professional engineer.
