it is better to learn computer when you are bored.

The basic contents of learning computer include:

Step 1: Learn to start the computer.

after connecting all parts of the computer, check whether the power cord of the host and monitor is connected properly, and then you can start the computer.

the POWER switch of the host computer is generally on the panel of the host computer, which is marked with the word power. Press it to turn on the power of the host computer, and then turn on the power switch of the monitor. After turning on the power of the host, the computer must first carry out self-test, which is referred to as self-test. At this time, you will see some English sentences on the screen of the monitor, which is the display of computer self-testing. It tells us what hardware equipment and what models the computer has, and at the same time checks whether the external equipment of the computer is faulty, whether the wiring is correct and so on. If the operating system installed on the computer is Windows1, a Windows1 startup interface will be displayed on the screen. Wait a little longer, and a welcome screen will appear on the screen. After that, the Windows1 desktop will appear on the screen, indicating that the Windows1 system has been successfully started.

the way to start the computer through the Power button is called cold start. After the computer started normally, it waited for the work order to be issued.

Step 2: Learn to use the mouse to give orders.

The mouse is one of the most popular pointer control devices at present. It is small in size, suitable for hand holding and easy to use, so that children can master it quickly. By moving the mouse, you can point to the target on the computer screen, and then press the mouse button to send commands to the computer. You can also hold down the mouse button and drag the target to the position where it should be placed on the screen, and then release the mouse button. When graphics and images are processed by computer, the dragging method is very simple and convenient.

moving the mouse on the mouse pad means that the light emitted by the light source under the mouse is reflected by the mouse pad, and then the mouse receives the movement signal and sends the information of mouse movement to the computer, so that the mouse pointer on the screen can be moved to the position corresponding to the mouse movement.

Because the mouse is very intuitive and handy to use, most software now uses the mouse for operation, including system software and application software. To make the computer run according to your will, you must first learn to use the mouse to give orders.

The correct way to lie down the mouse is to place the index finger and middle finger gently on the left and right keys of the mouse, the thumb, ring finger and little finger on both sides of the mouse, the palm of your hand naturally faces the mouse, and the wrist is lightly placed on the desktop.

Hold the mouse with your hand and gently slide it on the mouse pad. You will find that an arrow on the screen moves with it. This arrow is called the mouse pointer.

press the left mouse button quickly with your index finger, and then release it quickly, which is called clicking.

clicking the mouse or clicking usually refers to clicking the left mouse button. In fact, the right mouse button can also be clicked. The method is to press the right mouse button quickly with the middle finger and then release it quickly.

press the left mouse button quickly, and then release it twice quickly, which is called double-clicking.

move the mouse pointer to the target to be dragged, then press and hold the left mouse button to move the mouse to other positions, and finally release the mouse, and the target will move to the current position of the mouse pointer. It's called dragging.

in Word21, when the mouse pointer is displayed as the insertion point, press and hold the left mouse button to move the mouse to other positions, and finally release the mouse, and the area dragged by the mouse will become a blue background, indicating that this area has been selected. You can cut, copy and delete this area conveniently and accurately through the software.

Step 3: Learn to type with the keyboard.

in addition to the mouse, another indispensable method to control the computer is to use the keyboard to input instructions or data.

most of the computer input is text data, and the keyboard is the most common and commonly used device for inputting text data into the computer. We can input text with the help of letter keys and numeric keys on the keyboard.

using the keyboard to enter commands or data is more complicated than using the mouse. There are more than 1 keys on the keyboard, and they are not arranged alphabetically, so the positions are difficult to remember. If you enter each time, you should look down at the keyboard to find out where the key you need to press is before entering, and then look up to check whether the words you enter on the screen are correct, which is not only tiring, but also inefficient. There are some function keys with different uses on the keyboard. When operating a computer, you can press these keys to operate, and you can also press more than two keys at the same time to achieve a certain function, which is called combination keys. Such as: Shift+A, Ctrl+C, Ctrl+Alt +F1, etc.

tab key: normally, pressing this key can move the insertion point to the right by a few characters.

uppercase lock key: used to lock letters in uppercase.

shift key: in the typing keypad, there are 3 keys with two characters. When the shift key is combined with these keys, you can type the characters at the upper part of the keys.

control key: combined with other keys to form a control command.

shift key: combined with other keys to form various composite control keys.

space bar: the longest key on the keyboard, used to enter a space to move the insertion point to the right by one character.

Enter key: confirm to input the command or data into the computer. When inputting text, press Enter key to generate a new paragraph at the insertion point.

Backspace key: press the Backspace key once, and the insertion point on the screen will return to the existing position by one space, and the content of the returned space will be deleted.

forward slash: enter command parameters.

backslash: enter the directory path.

Windows key: open the start menu and select the required menu command.

application key: equivalent to clicking the right mouse button to open the shortcut menu of the currently selected object.

Cancel key: cancel an operation, exit the current environment or return to the original menu.

screen print key: copy the contents of the current screen to the clipboard,

scroll lock key: in the spreadsheet software, click and lock the cursor movement key to drive the whole spreadsheet to move, and the screen stops scrolling.

insert key: switches between insert and rewrite status.

delete key: delete the characters at the current insertion point, and all the characters to the right of the insertion point will be moved to the left by one character.

first key: the insertion point moves to the upper left corner of the screen.

tail key: the insertion point moves to the right of the last character of the current line.

page turn key: moves the insertion point to the previous page or the next page.

cursor movement key: moves the insertion point up, down, left and right by one character.

number lock key: press it once, the number lock indicator will light up, and the keypad area can be used to enter numbers.

Correct typing posture is very important, otherwise you will get tired easily, which will affect your typing speed, and over time, you will form bad habits and affect your health. Secondly, we must master efficient typing methods, that is, blind typing.

The correct typing posture is to face the computer and sit upright. ? When sitting in a chair, your waist should be straight, your upper body should lean forward slightly, your feet should be flat naturally, and you must not hunch over. In addition, you should pay attention to the height of the computer desk and chair, otherwise it will be very uncomfortable.

Secondly, when you hit a key, you should keep your fingers bent and arch up slightly. The first joint behind your fingertips is slightly curved and placed in the center of the eight benchmark keys.

Third, when you hit a key, you should hit the key vertically with your fingers, don't press the key, and don't let your fingers lie on the key. When you hit a key, the hard part is mainly your knuckles, not your wrists, which means you have to rely on your fingers to bend and stretch to complete the keystroke.

Fourth, you should be flexible when you hit a key. When you hit a key, you should press it vertically to the keyboard with your fingertips and immediately bounce back. Don't let your fingers stay on the key for too long.

a, s, d, f, j, k, l,; Eight keys are the most basic key positions for key input. The index finger and little finger of the left and right hands are placed on these eight basic key positions respectively, and the two thumbs are placed on the space bar. Then the typing keys on the keyboard are divided into several parts, and each finger is responsible for one or more of them. For example, the index finger of the left hand is divided into eight key positions: 4, 5, R, T, F, G, V and B, while the index finger of the right hand is divided into eight key positions: 6, 7, Y, U, H, J, N and M. The middle finger, ring finger and little finger of the left and right hands are generally only responsible for the four keys arranged obliquely from top to bottom.

There are also some function keys, such as shift key, control key, tabulation key, Windows key, etc. According to the left and right positions, the two little fingers of the left hand and the right hand are responsible respectively, and the longest space bar in the bottom row is the thumb of the left hand and the right hand.

Because the key positions in the keypad area and the function key area span greatly, the hand must leave the key position when pressing the key, so no special requirements are made. Learning to type should start from eight basic keys, and every time you hit any key, your fingers should return to the eight basic keys. These eight basic keys are the base of typing.

step 4: turn off the computer now.

After learning how to start the computer and how to operate the computer through the mouse, keyboard and other devices, learn the last step of controlling the computer-turning off the computer.

The operation process of turning off a computer is obviously different from that of turning off a TV set. Windows S1 needs to save some current status, latest settings and other information to the hard disk when shutting down the system. Directly turning off the power supply will not be able to save these information, which may affect the next startup. Incorrect shutdown method may not only lose your hard-earned work or some important information, but also cause such serious consequences as damaging the computer. Now this era is inseparable from computers. Without computers, we can't work efficiently. In 25, a computer user was anxious to get angry because his computer was broken. His temperature was 4 degrees and he didn't get well for several days. Therefore, we should not treat such a simple matter as turning off the phone just for convenience and rashly.

Under the Windows S1 operating system, the correct shutdown procedure is as follows:

Click ("click the mouse" or "click", generally referring to clicking the left mouse button) the start button in the lower left corner of the desktop, and a menu will pop up on the screen above this button, and the power options can be found at the bottom of this menu.

point to the power option at the bottom of the menu, and then click the left mouse button.

A sub-menu will appear. In this sub-menu, click the power off option with the mouse, wait a little while, and the power indicator light on the new computer host will go out automatically.

In computer operation, don't turn it off and turn it on immediately. This move is almost the same as the consequences caused by sudden power failure and sudden call, and it is easy to destroy the disk, motherboard and CPU.
