Off-road vehicle drivetrains. Later, during the 1990s, manufacturers started to add even more luxuries to bring those off-road vehicles on par with regular cars. This eventually evolved into what we call the SUV today. It also evolved into the newer crossover vehicle, where utility and off-road capability was sacrificed for better on-road handling and luxury. To be able to drive off the pavement, off-road vehicles need several characteristics: They need to have a low ground pressure, so as not to sink into soft ground, they need ground clearance to not get hung up on obstacles, and they need to keep their wheels
Capability-based addressing capability-based security. Two techniques are available for implementation: The designers of the System/38's descendent systems, including AS/400 and IBM i, removed capability-based addressing. The reason given for this decision is that they could find no way to revoke capabilities (although patterns for implementing revocation in capability systems had been published as early as 1974, even before the introduction of System/38). Capability-based addressing In computer science, capability-based addressing is a scheme used by some computers to control access to memory. Under a capability-based addressing scheme, pointers are replaced by protected objects (called capabilities) that can be created only through the use
