Solid State Drive (SSD) Basics
Why is a hard disk drive so slow compared to a solid state drive and why don't they just get rid of the hard disk drive, and store everything in solid state memory? Since 2006 computer manufacturers have been producing Solid State drive based PCs. More ...

Hardware Resources Explained
Hardware devices, such as modems, network circuits, sound circuits, and so on, require system resources such as Interrupt Request (IRQ) lines, Input/Output Port (I/O) addresses, Direct Memory Access Channels (DMA), and a range of Memory Addresses for storing code and data. Each device needs its own set of resources. If two devices attempt to use the same resource, your system may lock up or crash. More ...

Rambus DRAM (RDRAM) is a proprietary memory technology, designed by the Rambus Corporation, that is found in some Pentium III and Pentium 4 systems built between 2000 and 2002. When it was introduced it run at faster speed than conventional SDRAM. When DDR SDRAM was released, RDRAM became obsolete. More ...
PC Sound Circuitry
Actual physical sound is an analog phenomenon while the computer is digital. To output a sound stored on a computer disk to a speaker the sound circuit uses a digital-to-analog converter. Sound input to the computer for recording uses an analog-to-digital converter. So PC sound circuitry is primarily an AD/DA-converter or a "coder/decoder", usually shortened to "codec". More ...
