Working with the information, a person enjoys not only the noesis that remembers, but likewise books, reference books, and other external sources. The reckoner besides has 2 kinds of memory: (internal) and long term (external) memory. Structurally, these parts can exist combined in a single housing size book or each part may consist of several quite bulky devices. The circuit device of the computer: Working with the data, a person enjoys not only the knowledge that remembers, but as well books, reference books, and other external sources.

Although the computer is like a man on the basis of your device, only you can not identify the "computer intelligence" with the heed of human being. An important departure is that the computer piece of work is strictly subject to the pledged in his programme, but human being himself governs their actions. The programme - a reference to the sequence of actions (verbs) to be performed by a figurer to solve the problem of data processing. Thus, the PC software principle consists in that the estimator performs an activeness on a predetermined program. This principle provides the versatility of using a computer: a certain time solves the problem of the selected program, respectively. The data processed on a computer is called data. During execution of the program is stored in the internal memory. Although the estimator is like a man on the footing of your device, only you can not identify the "estimator intelligence" with the heed of man. An important deviation is that the estimator piece of work is strictly subject to the pledged in his plan, but man himself governs their actions. The program - a reference to the sequence of actions (verbs) to be performed by a figurer to solve the trouble of information processing. Thus, the PC software principle consists in that the computer performs an activeness on a predetermined programme. This principle provides the versatility of using a calculator: a certain time solves the problem of the selected program, respectively. The information processed on a computer is called data. During execution of the program is stored in the internal memory.

A computer is a collection of devices and programs that command the operation of these devices. Hardware - a system of interrelated technical devices that perform input, storage, processing and output of information. Software - a set of programs that are stored on your computer. Personal computer - a computer designed for personal utilise. Equally a dominion, a copy of a personal computer used by only i, or, in extreme cases, multiple users (for example, in the family). According to its characteristics it tin can be different from the mainframe, but functionally able to perform similar operations. According to the method of operation are distinguished desktop, laptop and pocket PC models. In the future, we will consider the desktop models and techniques for working with them. In today's marketplace a variety of reckoner equipment modifications and variations of computers is enormous, but even the most unusual set always includes the same kinds of devices. A figurer is a collection of devices and programs that control the operation of these devices. Hardware - a arrangement of interrelated technical devices that perform input, storage, processing and output of information. Software - a set of programs that are stored on your figurer. Personal computer - a computer designed for personal employ. As a rule, a copy of a personal reckoner used by only i, or, in extreme cases, multiple users (for example, in the family unit). According to its characteristics it tin be different from the mainframe, but functionally able to perform similar operations. According to the method of operation are distinguished desktop, laptop and pocket PC models. In the hereafter, we will consider the desktop models and techniques for working with them. In today's market place a variety of calculator equipment modifications and variations of computers is enormous, just even the most unusual set up always includes the same kinds of devices.

Monitor - a device for reproducing the visual grapheme and graphic data. It serves equally an output device. They vaguely resemble household televisions. The desktop computers are typically used to monitor cathode-ray tube (CRT) or flat-panel monitors, liquid crystal display (LCD). Monitors can have dissimilar screen size. Screen diagonal size is measured in inches (1 inch = ii.54 cm), and typically 17, 19, 21 or more inches. Monitor - a device for reproducing the visual character and graphic information.

Mouse - a device "graphical" command.Currently widespread optical mouse in which no mechanical parts. The light source placed within the mouse illuminates the surface, and the reflected low-cal is recorded by a photodetector and converted into movement of the cursor on the screen. Electric current models of the mouse may be wireless, ie, is connected to the computer without using a cablevision.

CPU. The microprocessor - the chief bit PC. All calculations are washed in it. The processor hardware is implemented on a large integrated circuit (LSI). Most of the integrated circuit is actually not large in size and is, on the contrary, a small flat semiconductor plate almost the size of 20x20 mm, enclosed in a flat case with rows of metal pins (contacts). BIS is the largest in number of elements. The use of mod high-engineering science allows y'all to put on the LSI processor huge number of functional elements, a size of merely about 0.13 microns (1 micron = 10-6 m). For instance, in a processor Intel Core ii Duo processor with four MB cache of about 291 million. CPU. The microprocessor - the master scrap PC. All calculations are done in it. The processor hardware is implemented on a large integrated circuit (LSI). Most of the integrated circuit is really not large in size and is, on the reverse, a pocket-size flat semiconductor plate about the size of 20x20 mm, enclosed in a flat example with rows of metal pins (contacts). BIS is the largest in number of elements. The apply of modern high-technology allows you to put on the LSI processor huge number of functional elements, a size of only about 0.13 microns (1 micron = ten-half-dozen 1000). For case, in a processor Intel Core ii Duo processor with 4 MB cache of well-nigh 291 million.

Advice Ports. For advice with other devices such equally a printer, scanner, keyboard, mouse, and so on. N., A computer equipped with a and then-called ports. Port - this is not just a connector for external equipment, although the port and the connector ends. Port - a more sophisticated device than a connector, which has its own chips and command software. Examples of ports: COM (serial port) LTP (parallel port) USB (consequent with high productivity) PS / 2 (generic mouse and keyboard) Communication Ports.
