How to install computer hardware

1. Classification of computer hardware

As people's demand for computer functions increases, users often replace and add computer hardware connections. There are a wide variety of hardware devices, but the installation process is similar, mainly in two cases: Plug and Play hardware device installation and non-Plug and Play hardware device installation.

2 installation of Plug-and-Play devices

Plug-and-play equipment refers to the device only connected to the computer, such devices are mainly removable storage (such as USB flash drive, mobile hard disk), keyboard and mouse, a few plug-and-play devices need to be in the case of computer power failure to connect, starting the computer can be used.

Here's how to install a plug-and-Play device with a USB drive. The USB drive is plugged into the computer, and the new hardware is automatically detected and prompted in the taskbar. Then the system automatically installs the driver of the USB drive, and when it is finished, it prompts the new hardware to be installed and ready to use.

Non-Plug and Play devices not only connect the device to the computer correctly, but also install the appropriate driver on the computer to use, such as printers, scanners, cameras and other devices are non-Plug and Play devices. The following is an example of installing a printer to explain its installation process.

The newly purchased printer cannot be used alone, must be connected to the computer, and the appropriate driver is installed so that the computer can correctly identify the printer model to print. Printers are generally divided into two types of port and USB, different printer driver installation methods are different, but the overall similarity. Because the parallel port belongs to the elimination of the interface, so most printers use USB interface, but also some printers both support the USB interface, and support the concurrent interface. Of course, a lot of people are still using old-fashioned printers that only support parallel ports. Although the interface is different, the connection method is similar to the method used.

　Connection of 3.USB Port printer

USB port printer Connection is relatively simple, and because the USB interface to support hot plug, in the computer running can also plug and the data line will not be damaged, easy to use.

Resolution Interface

A USB connection has two ports, the narrow and flat end of which is used to connect the computer, which is now set to B, a wider and shorter end to connect to the printer, now set it as a end.

Connection interface

Plug a end of the USB connection into the USB connector on the chassis. Plug the b end of the USB connection into the USB connector on the printer, and plug the power cord that came with the printer into the printer's power jack. Plug the other end of the power cord into the power outlet. This way, the printer is connected to the computer. If you can't even look at it, turn off the USB connector.

4-Port Printer connection

Parallel port printer connection and USB port printer connection method is similar, only the port used when the connection is different. The parallel interface of the computer is generally located behind the chassis and is a trapezoidal slot with a 15 pinhole. The printer's port is generally located behind the printer, when connecting to your computer, plug the parallel port printer data cable with 15 pins at one end of the rear of the chassis, while inserting the position of the trapezoidal port to coincide, and then inserting the other end of the data line into the parallel port of the printer. The way to connect to the printer power is the same as the USB power cable. After connecting to the printer's connection, you need to reinstall the printer's driver to use the printer parallel connector slot on the chassis. But this type of interface is now used.
