Solid State Hard Drive Technology Review
Solid state technology is composed of non moving semiconductor components, as opposed to electromechanical devices such as magnetic hard drives that rely upon moving read/write heads to store and retrieve data. Solid state hard drives (SSDs) have a low access time and run quieter than existing hard drives due to the lack of moving parts; [...]
[Read More]Advantages of a Printer Hard Drive
It is becoming increasingly common for businesses and even home users to have a printer hard drive. Due to the high resolution graphics now being used in all aspects of printing it is important to know why the printer hard drive is important and what it can do for you. A printer hard drive can [...]
[Read More]How Does an Integrated Circuit Work?
Integrated circuits are in almost every appliance known to man at this point in history from wristwatches to televisions and from coffee makers to, the most obvious, computers. An integrated circuit is a collection of diodes, transistors and microprocessors in miniature scale all operating on a single piece of semiconductor, typically silicon. Each performs a [...]
[Read More]Troubleshooting LCD Dipslay Issues
In the past, CRT monitors could display lower resolution in full screen as they are not confined by the number of or pixels in general; pixels were not used in CRT monitors. This presents a different set of solutions needed to correct low quality pictures on an LCD screen. An LCD monitor has to spread [...]
[Read More]What is LED Printer Technology?
The LED printer technology developed by Casio has invaded the color printer world for businesses and home users alike. LED printers are as fast if not faster than their competitive laser cousins. First and foremost LED printers use an array of light emitting diodes to repeatedly flash light directed toward an imaging drum. There are [...]
[Read More]How to Find Parts for HP Laptops
Trying to find HP laptop parts can be overwhelming, but following the parts search form on a site can be the simplest and easiest way to find the needed part. First locate the site and choose your country if available. Next find the type of part for which you are looking; for example input or [...]
[Read More]Battery Technology Overview – Part 2
While a nickel metal hydroxide (NiMH) battery has two to three times the capacity as a nickel cadmium battery, compared to lithium ion batteries the NiMH batteries have a lower density by volume and the self discharge rate is higher. An effect called “voltage depression” can occur in NiMH batteries due to partial discharging and [...]
[Read More]Battery Technology Overview – Part 1
There are three main types of battery technologies used in laptop computer batteries; the main difference is the chemical structure in which they store the electricity which affects their charging and discharging as well as the maximum voltages able to be held. Nickel cadmium batteries have a nominal cell potential of 1.2 volts, and changes [...]
