Computers are all around us. They look complicated, but the basics are easy to understand.
Computers are part of our daily life. Let's look at the patterns of how computers work.
The data consists of information patterns. These patterns change from one form of force to another. As an example, in a telephone, our voice changes into patterns of electricity and then back into sound patterns. Computers work with patterns of electricity, light and magnets! Let us first focus on E-pulses of electrical patterns.
When we turn over a light switch, we turn the power on and off. Computers turn power on and off billions of times a second. Now you know a part of the mystery how computers work. Tiny pulses of on or off current, we call e-pulses, make patterns that represent data. Before a computer works, all data must be changed into on or off-e pulses.
Look at a chip. It is full of lines and logic links. There are ways and processes. The e-pulses race on thin lines like cars on a super highway. Logic is the way in which digital data flow through the chip. The microprocessor chip is referred to as CPU or Central Processing Unit. The CPU uses directions to turn on and off small switches called transistors such as traffic lights to control the flow of e-pulses of data. This guide is software. Software controls the flow of data via a computer. It makes single letters into e-mails and separate numbers into balanced checkbooks. The CPU sends E-pulses to the computer screen. The first chip had a few thousand transistors. Today, chips have over a billion transistors.
The e-pulses switch to light points that illuminate the screen. Each point of the light is called a pixel. Each pixel has a red, green and blue part. Everything we see on the screen consists of light patterns. We call them L-patterns of pixels. That is, all the colors we see on the screen are actually small patterns of three colors of dots. The screen shows us what to do with the computer. The actual data is stored in the memory of the computer.

Individual computers are connected to a network called Internet. It connects different computers from all over the world. The "Web" is the name for all texts and images that people create.
How do computers work? The e-pulses flow into chips; Lights illuminate on the screen and magnets jam memories. The various computer parts integrate together to make a computer. The individual computers connect together to make the Internet and the worldwide web. Connected computers provide open access to much of the world's knowledge. May we interweave the data into wisdom that leads to global peace and prosperity.
Integrated chips enable the modern age of computers. The lines link circuits, networks and lives. We hope that easier global communication will lead to greater understanding..thats all the basic information about computer, thank you.
