RISC (reduced instruction set computer)

In the mid-1980s to early-1990s, a crop of new high-performance RISC microprocessors appeared, which were initially used in special purpose machines and UNIX workstations, but have since become almost universal in all roles except the Intel-standard desktop.

The first commercial design was released by MIPS Technologies, the 32-bit R2000. The R3000 made the design truly practical, and the R4000 introduced the world's first 64-bit design. Opposing projects would result in the IBM POWER and Sun SPARC systems, respectively. Soon every major vendor was releasing a RISC design, including the AT&T CRISP, AMD 29000, Intel i860 and Intel i960, Motorola 88000, DEC Alpha and the HP-PA.

Market forces have "weeded out" many of these designs, leaving the PowerPC as the main desktop RISC processor, with the SPARC being used in Sun designs only. MIPS continue to supply some SGI systems, but are first and foremost used as an embedded design, notably in Cisco routers. The rest of the original crop of designs have either disappeared, or are about to. Other companies have attacked niches in the market, notably ARM, originally intended for home computer use but since focused at the embedded processor market. Today RISC designs based on the MIPS, ARM or PowerPC core are the vast majority of computing devices.

Canoe

A canoe is a small narrow boat, classically human-powered, but also commonly sailed. Canoes usually are pointed at both bow and stern and are normally open on top, but can be covered.
In its human-powered form, the canoe is propelled by the use of paddles, with the number of paddlers depending on the size of the canoe. Paddlers face in the direction of travel, either seated on supports in the hull, or kneeling directly upon the hull. In this way paddling a canoe can be contrasted with rowing, where the rowers face away from the direction of travel. Paddles may be single-bladed or double-bladed.
Sailing canoes are propelled by means of a variety of sailing rigs. Common classes of modern sailing canoes include the 5m² and the International 10m² Sailing canoes. The latter is otherwise known as the International Canoe, and is one of the fastest and oldest competitively sailed boat classes in the western world. The log canoe of the Chesapeake Bay is in the modern sense not a canoe at all, though it evolved through the enlargement of dugout canoes.

Sandwich

A sandwich is a food item typically consisting of two pieces of leavened bread between which are laid one or more layers of meat, vegetable, cheese or jam, together with optional or traditionally provided condiments, sauces, and other accompaniments. The bread can be used as is, lightly buttered, or covered in a flavored oil to enhance flavor and texture. It is named after the 4th Earl of Sandwich.
Sandwiches are commonly carried to work or school in lunchboxes or brown paper bags to be eaten as the midday meal, taken on picnics, hiking trips, or other outings. In some parts of the world, they are also served in many restaurants as entrées, and are sometimes eaten at home, either as a quick meal or as part of a larger meal. When eaten as part of a full meal sandwiches are traditionally accompanied with such side dishes as a serving of soup (soup-and-sandwich), a salad (salad-and-sandwich), french fries/chips, potato chips/crisps and a pickle or coleslaw. A new trend appearing is making sandwiches into wraps, in which a tortilla is substituted for the bread. According to a recent court ruling in the United States, a sandwich must have two slices of bread and not one tortilla.

Tourism

Tourism is travel for predominantly leisure or relaxation purposes, and also refers to the prerequisite of services in support of this act. Tourists are people who ,travel to and stay in places outside their common environment for not more than one consecutive year for leisure, business and other purposes not related to work out of an activity remunerated from within the place visited.
Tourism has become an enormously popular, global activity. As a service industry, tourism has frequent tangible and intangible elements. Major tangible elements include transportation, accommodation, and other apparatus of a hospitality industry. Major intangible elements relate to the purpose or inspiration for becoming a tourist, such as rest, relaxation, the opportunity to meet new people and experience other cultures, or simply to do something different and have an adventure.
Tourism is crucial for many countries, due to the income generated by the expenditure of goods and services by tourists, the taxes levied on businesses in the tourism industry, and the prospect for employment and economic advancement by working in the industry.

HyperTransport

HyperTransport, formerly known as Lightning Data Transport, is a bidirectional serial/parallel high-bandwidth, low-latency point to point link that was introduced on April 2, 2001.The HyperTransport Consortium is in charge of promoting and developing HyperTransport technology. The technology is used by AMD and Transmeta in x86 processors, PMC-Sierra, Broadcom, and Raza Microelectronics in MIPS microprocessors, AMD, NVIDIA, VIA, SiS, and HP in PC chipsets, HP, Sun Microsystems, IBM, and IWill in servers, Cray, Newisys, and QLogic in high performance computing, Microsoft in its Xbox game console, and Cisco Systems in routers. Notably missing from this list is semiconductor giant Intel, which continues to use a shared bus architecture.
