Basic knowledge of computers for beginners, basic knowledge of computers for novices

What are the basic knowledge of computers.

People often distinguish between real computers according to their functions, so the main components of a computer are divided into five parts: controllers, combinators, memory, and input and output devices. If you only distinguish it from the appearance of the computer, the computer is just a host and a monitor and a keyboard and mouse.

When people use the input device of the computer, they can choose their favorite and skilled way, generally there are full spelling methods, five strokes and so on can be selected, but pay attention to the posture of the hand when typing, so as to be able to better use the computer.

Generally, the configuration of a computer refers to some basic hardware information of the computer, such as the model of the CPU, the size of the hard disk, and the size of the monitor. Users can search in the computer's properties, and if you click on the performance settings or advanced in the advanced section, you can see the options for visual effects and virtual memory and other devices, which are some basic daily operation methods and common sense.

Generally, we will see C, D, E, F disks in the computer, these disks refer to the partition of the hard disk, we all know that the computer generally has only one hard disk, but in order to better model operation, so the hard disk is divided into several areas, and in daily use, people use more C disk and D disk. These partitions were previously independent of each other, working without affecting the other partitions, and they have their own role. For example, the C disk is a system disk, which is generally used to install the operating system when it is used; The D disk is used to store software and some more important information; The E and F disks are used to store some more data or videos.

In addition to the computer can bring convenience to people, provide learning opportunities and work platforms, colleagues themselves also have a very rich operating knowledge and some basic knowledge that people need to learn, if people master these common sense, on the basis of enhancing their own understanding of the computer, they can also be more proficient in operating the computer, so as to deal with various situations when using the computer.

In the first step, place your finger on the keyboard. Eight fingers are placed on the eight basic keys, and two female fingers are lightly placed on the space bar.

The second step is to practice keystrokes. Lift your left hand about two centimeters away from the keyboard, and flick a key down with your middle finger while pressing down, and flick your other fingers slightly upwards at the same time, so that you can hear the sound of the key.

Step 3: Practice familiarizing yourself with the positions of the eight basic keys (please keep the correct keystrokes in step 2).

The fourth step is to practice the playing of non-basic keys. Lift the left hand about two centimeters away from the keyboard, the whole left hand slightly forward, while using the middle finger to flick down a key, at the same time the other fingers bounce up slightly, after the key four fingers quickly return to the position as shown in the figure above, pay attention to the right hand do not move, other keys similar to the way to play.

Correct posture: 1. The screen and keyboard should be directly in front of you, and the neck and wrist should not be in an oblique state.

2. The center of the screen should be lower than the level of your eyes The screen should be at least an arm's length away from your eyes.

3. Sit upright if you want to sit Don't sit half-sit and half-lie down, and don't let your body sit in an unorthogonal position.

4. The thighs should be kept parallel to the forearms as much as possible.

5. Hands, wrists and elbows should be kept in a straight line.

6. Put your feet on the floor or mat easily and steadily.

7. The height of the chair seat should be adjusted to your elbows with nearly 90 degrees of bending so that your fingers can naturally rest directly above the keyboard.

8. The lower back is attached to the back of the chair, and the bevel angle of the back is kept at about 10-30 degrees.

Basic knowledge: Generally, the computer we see is composed of three parts: the host (the main part), the output device (the monitor), and the input device (the keyboard hole and the mouse).

The host is the main body of the computer, and there are hardware such as motherboard, CPU, memory, power supply, graphics card, sound card, network card, hard disk, floppy drive, optical drive and other hardware in the main chassis.

Hardware is generally divided into a host computer and external devices, and the host is the core component of a computer, usually placed in a chassis. External devices include input devices (e.g., keyboards, mice) and output devices (e.g., monitors, printers), etc. Software is generally divided into system software and application software.

The type of CPU and clock frequency are the most important performance indicators of a computer, which determines the most basic performance of a computer. In the past, we used to say that we were called by the model of the CPU. The speed of a computer is mainly determined by the speed of the CPU and memory.

Clock frequency is a measurement method for a computer to work according to a fixed beat, also known as the main frequency, the higher the clock frequency, the shorter the clock cycle, the shorter the time it takes to execute the instruction, and the faster the operation speed.

The unit of memory is MB, usually people always say how much MB my memory refers to this, such as 32MB, 64MB, 128MB, 256MB, etc., a computer, the larger its memory capacity, the more complex the tasks that the computer can handle, and the faster the speed will be.

Novices can start from the following aspects: the first stage: familiar with the operation of the mouse and keyboard; Phase 2:

learning the basics of operating systems; The third stage: learn system tools and simple application software; Learn and become proficient in some software that is closely related to your work.

Specifically:1The main actions of the mouse are: move, drag, click, double-click and right-click. Mastering the operation of the keyboard can be done by typing exercises.

2.System knowledge is first of all the learning of Windows 98. Find a relevant book or a related learning CD-ROM to study systematically. And be sure to learn and operate at the same time.

It's best to learn word systematically. Once you've mastered Word, you'll have a sense of being able to learn other applications. You'll find that apps have a lot in common.
