IV. Translate the following text into your native language:
Once the data and instructions are input, the computer must be able to store them internally and then process the data based on instructions. This storage and processing, which occurs in the processing/internal memory unit, can involve many different types of operations, including arithmetic operations (addition, subtraction, and so on) on numbers, operations on letter of the alphabet, and operations that result in the pictures (known as graphics). The processing/internal memory unit is comparable to the human brain, which also stores and operates on data. For example, the PC processes the weather data to check them for reasonableness and prepare them for further processing by the mainframe.
Because the internal memory of a computer does not have an unlimited capacity, a storage area is needed outside of the computer to hold the data and information, which can be brought back into the internal memory as needed. This external storage unit is called secondary storage. Another reason for having secondary storage is that computer’s internal is erased when the power to the computer is turned off. Anything in internal memory that must be saved before the power is turned off should be transferred to secondary storage. The file cabinets we use to save large amounts of data and information are analogous to computer’s secondary storage.
Finally, because the proceeded information is of no use unless it is provided to the user, the computer has a process called output. We humans output the results of our brains’ operations in the form of speech, writing, pictures, or body movements.
