Read and translate the text in writing. Storing information
Computers can store information in two types of locations during the computing process – the memory and file storage devices. Memory, which is built into the computer, holds instructions and data during processing. File storage devices provide long-term storage of large amounts of information.
Memory, also called the internal memory or main memory, stores information and programs inside the computer. The memory receives data and instructions from an input device or a file storage device. It also receives information from the processor. The memory stores only the information that is currently needed by the processor. After the processor has finished with it, the information is transferred to file storage devices form permanent storage of sent directly to an output device for immediate use.
File storage devices, also called auxiliary storage units, can store huge amounts of information for long periods of time. Such units are slower than the memory that is built into the computer. But they can hold much more information, and they are less expensive. For this reason, file storage devices are commonly used to store large quantities of data, programs, and processed information.
The most important file storage devices are magnetic disks and magnetic tapes. To read information from a disk or tape, the drive unit and sends them to the memory. Magnetic disks are said to be random-access devices because any part of the information on them can be inspected or replaced with ease.
Some other types of file storage devices contain read-only memory (ROM) – information that the computer cannot change. ROM units may consist of a compact disc, a cartridge, or a silicon chip. They are used to store large databases and programs for computer games.

The bus enables the components in a computer, such as the CPU and the memory circuits, to communicate as program instructions are being carried out. The bus is usually a flat cable with numerous parallel wires. Each wire can carry one bit, so the bus can transmit many bits along the cable at the same time. For example, a 16-bit bus, with 16 parallel wires, allows the simultaneous transmission of 16 bits (2 bytes) of information from one component to another. Early computer designs utilized a single or very few buses. Modern designs typically use many buses; some of them specialized to carry particular forms of data, such as graphics.
Input devices, such as a keyboard or mouse, permit the computer user to communicate with the computer. Other input devices include a joystick often used by people who play computer games; a scanner, which converts images such as photographs into digital images that the computer can manipulate; a touch panel, which senses the placement of a user’s finger and can be used to execute commands or access files; and a microphone, used to input sounds such as the human voice which can activate computer commands in conjunction with voice recognition software. “Tablet” computers are being developed that will allow users to interact with their screens using a penlike device.
Information from an input device or from the computer’s memory is communicated via the bus to the central processing unit (CPU), which is the part of the computer that translates commands and runs programs. The CPU is a microprocessor chip—that is, a single piece of silicon containing millions of tiny, microscopically wired electrical components. Information is stored in a CPU memory location called a register. Registers can be thought of as the CPU’s tiny scratchpad, temporarily storing instructions or data. When a program is running, one special register called the program counter keeps track of which program instruction comes next by maintaining the memory location of the next program instruction to be executed. The CPU’s control unit coordinates and times the CPU’s functions, and it uses the program counter to locate and retrieve the next instruction from memory.
