Plug and Play Resource Allocation
Early PCs used a bus called Industry Standard Architecture (ISA). ISA devices cannot share resources, each ISA device must have its own IRQ. In 1993, Microsoft and Intel developed Plug and Play (PnP) to solve this problem. More ...
Rambus DRAM (RDRAM)
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 ...

Hard Drives - ATA versus SATA
with data rates hitting the 133MB / sec mark the parallel ATA standard is maxing out, thus industry leaders got together and came up with a new standard known as Serial ATA (SATA). More ...
How to Build a Computer
Branded computers can offer both value and performance, yet parts are often short-spec in one place or another. Sadly you'll often get a performance "bottleneck" such as a slow graphics card, only a basic amount of memory, or a slimline motherboard with too few upgrade slots. Luckily, computers are surprisingly easy to build. 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 ...
