interactive pc help

It is one of the most revolutionary and powerful tools ever developed! It stands in the company of the wheel, the aircraft wing and the internal combustion engine because of the tremendous changes it has and still continues to make in our lives.
Lead Generation
Together with the its close cousins, the Internet and the web, a global, instantaneous communications network now exists in a way no one dreamed of when the first commercial PC appeared in 1981.

This Web site was developed to help non-technical people take full advantage of this powerful technology. On the surface, its workings are not at all intuitive, and probably appear somewhat mysterious. It is just the opposite! It is a very well ordered, logical machine.

Our aim is to take a some of the mystery out of it for you!

Where do we begin?

There are different ways to study any system. One is by describing each component. In Hardware each component of the PC is described to provide a basic understanding of how each one works. This type of analysis by itself doesn't provide an understanding of the how the PC functions as a unit.

In PC Basics we talk about the different functions in a PC and what they do. At the end we show you the bigger picture where they all come together to make the PC work. - world of warcraft powerleveling EU::wow powerleveling EU::wow power leveling US::world of warcraft power leveling US::

Processor - At the heart of every PC is the central processing unit, CPU for short. The CPU plugs into a motherboard which has a lot of other chips and electronics on it. The CPU and other components work together to schedule, compute and control everything that happens in the PC.

You've probably seen the 'Intel Inside' appearing in many computer sales ads. They are referring to the Intel CPU which is often a Pentium or Celeron processor.
Input - devices that allow you to direct the action of the PC. The keyboard and mouse enable you to control the computer by giving it directions (input).
Output - devices that display or produce results for you. The video display and printer are the primary ones. The speakers beep, chime etc., to let you know an action is completed and they also play your favorite MP3 files.
Memory - is temporary storage used by the CPU to store results of calculations or files brought in from the hard drive. Memory is very fast and volatile which means it loses it's information when power is removed. The memory cells are housed in Integrated Circuits (ICs), or chips as they are often called.
Storage - devices that retain information magnetically (Hard Disk Drive and Tapes) or optically (CD and DVD). They are not as fast as memory but can store much more data. They do not lose their information when power is removed.
Software - these are instructions, also known as programs or code. Software is to the CPU, what knowledge is to our human brains. The CPU and software work very closely together. Each one by itself is useless. Only when they work properly together can they direct and execute activities in the PC in a productive way.
