NiCad stands for nickel-cadmium, the materials used in the battery packs for many notebook computers. NiCad batteries can provide considerable power, but they need to be recharged every three or four hours. Full recharging can take as much as twelve hours, although newer batteries can be recharged in just a few hours.
Older NiCad batteries suffer from a phenomenon known as the memory effect. If they were only partially drained and then recharged, they lost their capacity to be fully charged. This is not such a problem with modern NiCad batteries.
Even with full drainage (called deep discharging), all batteries have a limit to the number of times they can be recharged. The maximum for most NiCad batteries is about one thousand recharges.
- NiMH battery pack
NiMH stands for Nickel-Metal Hydride, the materials used in some battery packs. Unlike NiCad batteries, NiMH batteries do not use heavy metals that may have toxic effects. In addition, they can store up to 50% more power than NiCad batteries and do not suffer from memory effects.
- Nimrod Routing Architecture
An internetwork routing architecture that can be applied to routing both within a single routing domain and among multiple routing domains. Nimrod works by separating the identification of communicating entities, called endpoints, from any topological information. It uses Endpoint Identifiers (EIDs) to specify and identify entities connected to the network. The subsystems which are covered […]
In Northbridge/Southbridge chipset architecture designs, the Northbridge is the chip or chips that connect a CPU to memory, the PCI bus, Level 2 cache and AGP activities. The Northbridge chips communicate with the CPU through the FSB. The Northbridge chip is one of two chips that control the functions of the chipset. The other is […]
A prominentnetwork software company. Its flagship product, Netware, has been a corporate standard for building local-area networks (LANs) for more than a decade. Novell was founded in 1983.
The expansion bus for versions of the Macintosh computers starting with the Macintosh II and ending with the Performa. Current Macs use the PCI bus.
