In some countries, notably the United States, SUVs are "not" classified as cars, but as "light trucks". SUVs overtook lower medium segment cars to become the world's largest automotive segment in 2015,
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
