How to learn computer

How to learn computers: first understand the basic components of the computer; then understand the wiring of the computer. The wiring here refers to the wiring outside the host chassis and the wiring inside the chassis; then master the basic operations of the computer, such as turning on and off the computer. , the use of mouse and keyboard; and finally master the basic operations of the operating system.

So for those who are new to computers, how should they learn computers? What do you need to learn? Today, Grasshopper is here to tell you what computer beginners need to know and where to start. I hope it will be helpful to you who are just getting started!

1. Understand the basic components of computers

Computers are also called microcomputers. Computers are composed of software and hardware. We can see it with the naked eye. What comes first is the hardware. For beginners, we need to first understand the basic components of a computer.

A desktop computer is mainly composed of a host chassis, a monitor, a mouse and keyboard, and external audio equipment. You can clearly see these devices in the picture above. There are also: power supply, motherboard, CPU, memory module, and graphics card inside the host chassis. , hard disk, optical drive (optional), network card, sound card (usually integrated on the motherboard), heat sink and other components. Beginners can open the computer case and identify all the components one by one to deepen their impression. In addition, you can also go online to learn about the functions, specifications and parameter meanings of each component.

2. Computer wiring

The wiring mentioned here refers to the wiring outside the host chassis. The wiring inside the chassis does not require beginners to master it. The external wiring is The most basic thing, otherwise I worry that many people won’t know how to wire it once they pull out the plug! Grasshopper I was playing computer games at my brother's house. He unplugged all the external cables because of lightning protection. Then I struggled for a long time before turning on the computer, but I never got access to the Internet. It wasn't until he came home that I realized that I still had the computer. One cord is not plugged in. Hey, I was so ignorant back then!

In order for the computer to be used normally and able to access the Internet, the following lines need to be connected correctly:

1. Wiring between the monitor and the host

The display data line is mainly divided into There are several interfaces such as VGA, DVI, HDMI, etc. No matter which interface is used, just plug one end into the monitor and the other end into the interface on the back of the host computer. The computer interface has an error-proof mechanism, and the wrong interface cannot be plugged in. The following is a schematic diagram of the socket:

In the above picture, the sockets of the integrated graphics card and independent graphics card are used to plug in the display data cable. Use our common VGA interface display data cable, plug one end into the host, and the other end into On the monitor

2. Host power cord, monitor power cord

The host power cord and monitor power cord have the same sockets. It is not a big problem to use them alternately during use. Just plug in one end. row, plug one end into the socket of the host and the monitor

3. Network cable

Network cable, we need a two-way network cable with a crystal head. If there is a router, connect one end to the router and the other end. The network cable socket of the host computer does not have a router. If you use a modem (modem) to dial up the Internet, one end is connected to the network cable port of the modem and the other end is connected to the network cable socket of the host computer.

3. Basic computer operations

1. Turn on and off

Beginners, the first thing they need to learn is the correct power on and off. It is not recommended. Use the hibernation function.

Turning on is very simple, just press the power button of the host. The monitor does not need to be turned off. If it is turned off, just press the switch of the monitor. However, after turning it off, don't forget to turn it on next time you turn on the computer. Otherwise, the monitor will be black and unresponsive because the monitor is not turned on. You may even think that the computer is broken and scare yourself.

The focus here is on shutting down the computer. I have met many people who do not understand computers. After using the computer, they directly unplug the power supply of the host, directly turn off the power strip switch, or press the power button to shut down. I have a friend whose wife unplugged the computer directly after using it. Later, the computer wouldn't turn on, so she came to ask me what happened. He said he had told his wife many times, but she turned off the phone cruelly as always! The correct way to shut down is (win7 system as an example): click "Start" in the lower left corner of the computer desktop, and then click to shut down the computer. If there is no mouse, you can also press the win key and left arrow key of the keyboard in sequence. Press the Enter key ('win -> Enter') to shut down.

2. How to use the mouse

The use of the mouse is the most basic operation of the computer. If you don't know how to use the mouse, it is equivalent to not knowing how to use your own hands.

Left button: Use the left button of the mouse. Click (click once) to select. Press and hold to drag the file. Double-click (click twice in succession) to open the file or software.

Right click: The function of the right mouse button is very simple, which is some functional attributes. Move the mouse cursor to the shortcut of a certain file, right click the mouse, and you can see many operations, including: copy, paste, and repeat. A series of operations such as naming, deletion, compression, sending, attributes, etc.

Pulley: The most common use of pulleys is to turn pages. After opening a web page, we can use the pulley to slide forward and backward to turn the page up and down. We can also use the pulley to turn pages when opening a word document.

3. How to use the keyboard

The keyboard has many keys, so I won’t introduce them one by one here. When using the keyboard, beginners must first learn how to type and switch input methods. , when Grasshopper first started typing, he just didn’t know how to switch the input method and couldn’t type Chinese. Find someone who knows how to do these operations and teach them!

4. Basic operations of the operating system

For computer beginners, I think some operations that must be mastered are:

a. Folder creation , move, rename, delete, copy (copy), paste;

b, file creation, move, rename, delete, copy, paste, open (double-click to open);

c. Typing, you can use Pinyin, Wubi, handwriting, voice input, etc. There is always a method that suits you;

d. Download and install the software;

e. How to use a browser to access the Internet ;

f, use QQ to type and chat;

g, use U disk to move files;
