In the era of strong development of science and technology like today, for students, in addition to familiar people such as fake books, rulers, etc., we also have another special friend: Microcomputers. count.
The first computer was born in 1956. Initially, the computer was very large, it was the size of an entire room and could only perform a few simple tasks. Over time, with the efforts of scientists, the size of the computer has been reduced to what it is today.
A desktop computer consists of two separate parts, the CPU
and screens. CPU is the most important part of the computer, it is processing very sophisticated information data. The CPU has a rectangular box shape, the size is usually 50 cm * 10 cm * 40 cm. The outside is made of metal with an insulating coating.
Inside are hard drives, microprocessors, electrical circuits, wires ... The front of the computer is a rectangle with dimensions of 10 cm * 40 cm. There are small parts to receive software, USB connection and machine, button control system ... The back of the CPU is a wire socket that connects the CPU to the power, monitor, keyboard and mouse pointer.
Shape calculators are typically the same size and design as a 21-inch computer. But today due to the development of technology, the computer screen only stops at 2 cm to 3 cm and is made of crystal.
In addition to the two sides, a keyboard and mouse pointer are also required to complete a computer. The keyboard is rectangular, about 16 cm * 25 cm in size, with prominent letters to help input information into the machine. The mouse pointer is small, fits in the hand, has three buttons to control the commands on the screen.
The simple computer use. For students, the main tools are creating documents, using software applications, exploiting the Internet and ... playing games!
To use the machine, before, we must be socket to the power, on the CPU and on the screen. Next, if creating a text, we double-click the left mouse button on the "W" (microsolf word) icon on the screen and use the letters, match ... enter information into the blank page on the screen. To use other program, we also open the machine and use the keyboard and mouse mouse to enter the information and create a command.
Thanks to computers, learners can exchange learning and emotional information quickly and conveniently, can view and perform experimental and chemical systems, can search for necessary information. essential for learning... Also, we can entertain ourselves by playing computer games...
Computers are extremely useful friends for learners. To protect your special someone, we need to regularly clean the keyboard, dust the server parts. In addition, we need to let the machine dry, avoid moisture. In particular, it is recommended to install a "virus" program - the author can destroy data in the machine.

Hok tốt nha ^^

Gửi bạn câu trả lời ạ!!!

bạn thêm cho mình từ "the first" vào đằng sau từ 'It" từ dưới lên nhé!

While playing games is a stress reliever for many people, playing for long periods of time can make users addicted.
