1.1 Electricity
It is impossible to imagine our civilization without electricity: economic and social progress will be turned to the past and our daily lives completely transformed.
Electrical power has become universal. Thousand of applications of electricity such as lighting, electrochemistry and electrometallurgy are longstanding and unquestionable.
With the appearance of the electrical motor, power cables replaced transmission shafts, gear wheels, belts and pulleys in the 19-th century workshops. And in the home a whole range of various time and labour saving appliances have become a part of our everyday lives.
Other devices are based on specific properties of electricity: electrostatics in the case of photocopying machine and electromagnetism in the case of radar and television. These applications have made electricity most widely used.
The first industrial application was in the silver workshop in Paris. The generator – a new compact source of electricity – was also developed there. The generator replaced the batteries and other devices that had been used before.
Electric lighting came into wide use at the end of the last century with the development of the electric lamp by Thomas Edison. Then the transformer was invented, the first electric lines and networks were set up, dynamos and induction motors were designed.
Since the beginning of the 20th century the successful development of electricity has begun throughout the industrial world. The consumption of electricity doubles every ten years.
Today consumption of electricity per capita is an indicator of the state of development and economic health of nation. Electricity has replaced other sources of energy as it has been realized that it offers improved service at reduced cost.
One of the greatest advantages of electricity is that it is clean, easily-regulated and generates no by-products. Applications of electricity now cover all fields of human activity from house washing machines to the latest laser devices. Electricity is the efficient source of some of the most recent technological advances such as the laser and electron beams. Truly electricity provides mankind with the energy of the future.
1.2 The monitor
We interact with computers by entering instructions and data into them. After the information has been processed, we can see the results (i.e. the output) on the visual display unit or the monitor. In this interactive process with the computer, the screen plays an important part.
The pictures and the characters we see on the screen are made up of picture elements which are also called pixels. The total number of pixels the display is divided in (both horizontally and vertically) is known as resolution. When the number of pixels is very large, we obtain a high resolution display and therefore a sharp image. If the number of pixels is small, a low resolution is obtained. Thus, pixel density or resolution affects the quality of the image: a larger number of pixels gives a much clearer image.
The cathode ray tube of the monitor is very similar to that of a TV set. Inside the tube there is an electron beam which scans the screen and turns on or off the pixels that make up the image. The beam appears in the top left corner, and scans the screen from left to right in a continuous sequence, similar to the movement of our eyes when we read, but much faster. This sequence is repeated 50, 60 or 75 times per second, depending on the system.
In a colour monitor, the screen surface is coated with substances called phosphors. Three different phosphor materials are used – one each for red, green and blue. A beam of electrons causes phosphor materials to give coloured light from which the picture is formed. Colour monitors are capable to display many different colours at the same time.
Portable computers use a flat liquid-crystal display (LCD) instead of a picture tube.
