Помогите перевести текст COMPUTER OPERATIONS . TYPES OF DATA Much of the processing computers can be divided into two general types of operation. Arithmetic operations are computations with numbers such as addition, sub­traction, and other mathematical procedures. Early com­puters performed mostly arithmetic operations, which gave the false impression that only engineers and scien­tists could benefit from computers. Of equal importance is the computers ability to compare two values to deter­mine if one is larger than, smaller than, or equal to the other. This is called a logical operation. The comparison may take place between numbers, letters, sounds, or even drawings. The processing of the computer is based on the computer's ability to perform logical and arithmetic op­erations. Instructions must be given to the computer to tell it how to process the data it receives and the format needed for output and storage. The ability to follow the program sets computers apart from most tools. However, new tools ranging from typewriters to microwave ovens have em­bedded computers, or built-in computers. An embedded computer can accept data to use several options in it's program, but the program itself cannot be changed. This makes these devices flexible and convenient but not the embedded computers itself. Types of data With the advent of new computer applications and hardware, the definition of data has expanded to include many types. Numeric data consists of numbers and decimal points, as well as the plus (+) and minus (-) signs. Both arithmetic operations and logical operations are per­formed on numeric data. This means that numbers can be used for calculations as well as sorted and compared to each other. Text, or textual data, can contain any combination of letters, numbers and special characters. Sometimes tex­tual data is known as alphanumeric data. Various forms of data that we can hear and see makes up audio-visual data. The computer can produce sounds, music and even human voice. It can also accept audio-information as an input. Data can also take form of draw­ings and video sequences. Physical data is captured from the environment. For example, light, temperature and pressure are all types of physical data. In many large buildings, com­puter systems process several kinds of physical data to regulate operations. Computers can set off security alarms, control temperature and humidity, or turn lights on and off, all in response to physical data. These applications increase people's safety and save the time and money.
