How EUV Chipmaking Works

Silicon microprocessors are about to reach the limit to their storage capacity. But one technology may extend the life of the silicon microchip -- it's called extreme-ultraviolet lithography, and it may keep silicon useful for a few years longer.

How Graphics Cards Work

The images you see on your monitor are made of tiny dots called pixels. At most resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with every one in order to create an image. How do graphics cards change this process?

How Microprocessors Work

The microprocessor determines the processing power available for any application you run -- without it, there IS no computer. Learn all about this amazing, ever-shrinking technology that makes your computer compute.

How Semiconductors Work

Semiconductors form the heart of modern electronics. Learn about semiconductors, silicon, doping, diodes and other fascinating technologies.

Is it true that the Mac G4 processor is twice as fast as a Pentium III?

In this article we'll tell you which processor is faster and why. Learn how chip designers make use of transistors.

On a microprocessor like a Pentium or a G5 why can't they simply crank the speed up to 1000 GHz?

A microprocessor will perform without error when executed at or below the maximum indicated speed. Why can't they speed them up? There are two things that limit a chip's speed.

What is the difference between a Pentium and a Celeron processor?

When you sort things out and compare the two chips side by side, it turns out that a Celeron and a Pentium 4 chip running at the same speed are different beasts. You should choose a chip based on how you use your computer.
