Since fractional parts of thing may be written either as common actions or as decimal fractions, we should be able to change a decimal 'action to a common fraction.

To change a decimal fraction to a common fraction take out the decimal point and write the decimal numbers as the numerator of the •action. For the denominator write the number as shown by the name of le last decimal place. Reduce the common fraction to lowest terms.

Дроби, знаменателями которых являются числа, выраженные единицей с последующими нулями (одним или несколькими), называются десятичными. Из двух десятичных дробей та больше, у которой число целых больше; при равенстве целых та дробь больше, у которой число десятых больше. Перенесение запятой на один знак вправо увеличивает число в десять раз. Чтобы увеличить его в сто раз, нужно перенести запятую на два знака вправо и т. д.

Computers what is a computer?

The term computer is used to describe a device made up of a combination of electronic and electromechanical (part electronic and part mechanical) components. Computer has no intelligence by itself and is referred to as hardware. A computer system is a combination of five elements:

• Hardware

• Software

• People

• Procedures

• Data/information

When one computer system is set up to communicate with another computer system, connectivity becomes the sixth system element. In other words, the manner in which the various individual systems are connected - for example, by phone lines, microwave transmission, or satellite - is an element of the total computer system.

Software is the term used to describe the instructions that tell the hardware how to perform a task. Without software instructions, the hardware doesn't know what to do. People, however, are the most important component of the computer system: they create the computer software instructions and respond to the procedures that those instructions present.

The basic job of computer is processing information. Computers accept information in the form of instruction called a programme and characters called data to perform mathematical and logical operations, and then give the results. The data is raw material while information is organized, processed, refined and useful for decision making. Computer is used to convert data into information.
