An optical mouse uses a light-emitting diode and photodiodes to detect movement relative to the underlying surface, unlike wheeled mice which use a set of one rolling ball and two chopper wheels for motion detection. Early optical Mice Early optical mice, first demonstrated by two independent inventors in 1980, came in two different varieties: Some, [...]

CPU Speed
May 20th, 2010 · No Comments · CPU, Processors
CPU speed is not a reliable indicator of CPU performance. Many factors inside and outside of the CPU exert a significant impact on CPU performance, and on overall system performance. The CPU CPU speed is measure in megahertz. A 1MHz CPU can accomplish one million CPU cycles in one second. Does this mean that a [...]

What are the Components of a CPU?
May 18th, 2010 · No Comments · CPU, Introductions
At the “heart” of every computer lies the CPU, or central processing unit, which is responsible for carrying out arithmetic and logic functions as well as executing instructions to other components. The components of a CPU work together, and depending on how they are made, determine exactly how fast these operations can be carried out [...]

Processor Cooling Basics
March 14th, 2010 · No Comments · Cooling, CPU, Introductions, Processors
It’s important to know a few basic facts about processor cooling. All desktop processors available today are pretty easy to handle, as the actual processor die is protected by a large metal plate covering the entire upper part of a processor. This metal plate is called the heat spreader, as it provides a larger footprint [...]
