Description for PC
The PC (Personal Computer) consists of a central unit, referred to as the computer has various components (a part which combines with other parts to form something bigger such as the motherboard, CPU, RAM). The computer is a box which contains most of the working electronics connected with cables to the components. There is easy way to think about the computer. If one thinks a computer as a human body, the components will be the parts of the human body such as a heart, a brain, a lung, a stomach. If one does not have any one of them, one may have a ring on one's head and knock on death's door. The computer is the same as a body structure; therefore, the computer will not work correctly, if one of components is not work. There are many components in the computer; however, the silvery small square box, the CPU, is certainly the most important PC component. Without the CPU, there would be no PC on the earth. The CPU has hundreds of needles at the bottom; moreover, the size is the same as a biscuit that can be taken in a bite. The CPU stands for Central (the center of PC data processing) Processing (the processing, moves and calculates, data) Unit (a chip, which contains millions of transistors). One can
The power supplier cannot do anything unless the invisible power, electricity, gives the delicious foods, the energy. The computer's development will never stop; therefore I hope people in our world can handle their friend, the PC, expertly. If the sons and the daughters follow their mother's rules well, the work will be no problem (error or break down in computer system). The motherboard is like mother and all of the other components, including the cooling fan, the CPU, and the RAM, are like sons and daughters. There are more components in a computer, such as a sound card (For listening to music through the speaker), a modem (For internet use), a CD-Rom (T run a CD), a CD-R Rom (For burning a CD), a DVD-Rom (To run a DVD disk), and a Floppy disk (To run small capacity disk). The drives (the devices for storing computer information) do this job, typically the silvery lunch box called a hard drive. Instead of a shower or a rest, the CPU has the smallest square shaped fan called a cooling fan (cooling device) that protects the CPU from melting down. However, if the brain does not have the memory that it calculated, the work will come to nothing; therefore, the brain needs to memorize what it calculated. The smallest and the cleverest brain can calculate the total amount of a hundred and one coins. The computer's heart is very different from the human heart. If electricity disappears, the computer might never run again. Finally, the brain can do memorize thousands of coins; however, it will forget the amount after 5 months if the brain will not take a note somewhere. Furthermore, the data note (hard drive files) will never erase unless you burn it (break down) or a goat eats it (a virus infection). There is an easy way to think about the motherboard.
