Software
Software basically is the distinct image or representation of physical or material position that constitute configuration to or functional identity of a machine, usually a computer. As a substance of memory, software in principle can be changed without the alteration to the static paradigm of the hardware thus without the remanufacturing thereof. Generally software is of an algorithmic form which translates into being to a progression of machine instructions. Some software, however, is relational forms which translate into being the map of a recognition network.
Software is a program that enables a computer to achieve a specific task, as contrasting to the physical components of the system. This include application software such as a word processor, which enables a user to achieve a task, and system software such as an operating system, which enables other software to run suitably, by interfacing with hardware and with other software.

Hummingbird
Hummingbirds are small birds in the family Trochilidae, inhabitant only to the Americas. They are known for their aptitude to hover in mid-air by quickly flapping their wings, 15–80 times per second (depending on the species). The Giant Hummingbird's wings beat 8–10 beats per second, the wings of medium sized hummingbirds beat about 20–25 beats for each second and the smallest beat 70 beats per second. Capable of continued hovering, the hummingbird has the ability to fly intentionally backwards (this is the only group of birds able to do so or vertically, and to maintain position while drinking from flower blossoms. They are named for the feature hum made by their wings.
Hummingbirds are involved to many flowering plants—shrimp plants, Bee Balm, Helicon, Butterfly Bush, Hibiscus, bromeliads, cannas, verbenas, honeysuckles, salvias, pentas, fuchsias, many penstemons. It is frequently stated that they are especially attracted to red and yellow flowers.

Robotics
It is the science and technology of robots, their plan, manufacture, and application.Robotics requires functioning information of electronics, mechanics, and software. A person functioning in the field is a roboticist. The word robotics was first used in issue by Isaac Asimov, in his science fiction short story "Runaround" (1941).
Although the outside and capabilities of robots vary extremely, all robots share the features of a mechanical, movable structure under some form of control. The chain is misshapen of links, actuators and joints which can allow one or more degrees of freedom. Most modern robots use open sequential chains in which each link connects the one before to the one after it. These robots are called serial robots and often look like the human arm. A few robots, such as the Stewart platform, use closed parallel kinematic chains. Other structures, such as those that imitate the mechanical structure of humans, diverse animals and insects, are relatively rare. However, the development and use of such structures in robots is a dynamic area of research. Robots used as manipulators have a finish effector mount on the last link. This end effector can be something from a welding mechanism to a mechanical provide used to manipulate the environment.

Hardware and software design
Supercomputers using custom CPUs traditionally gained their speed over conventional computers through the use of innovative designs that allow them to carry out many tasks in parallel, as well as complex feature engineering. They tend to be expert for certain types of computation, usually numerical calculations, and perform poorly at more general computing tasks. Their memory hierarchy is very cautiously designed to ensure the processor is kept fed with data and commands at all times—in fact, much of the performance difference between slower computers and supercomputers is due to the memory hierarchy. Their I/O systems tend to be planned to support high bandwidth, with latency less of an issue, because supercomputers are not used for transaction processing.
As with all highly parallel systems, Amdahl's law applies, and supercomputer designs devote great effort to eliminate software serialization, and using hardware to speed up the remaining bottlenecks.

Waka
In the Maori language, waka are Maori watercraft, generally canoes. Similar craft are encountered in
Waka range is from small, lightweight canoes, such as waka tiwai used for fishing individuals, during very large waka taua, manned by up to eighty paddlers and up to fourty mtrs in length, large double-hulled canoes for oceanic voyaging.
Many waka are single-hulled vessels set from hollowed tree trunks. Small waka consist of an only piece while large waka usually consist of some pieces jointed and lashed together. Some waka, mainly in the
Ocean waka, Paddled could be in any size, but were generally propelled by sail. Waka taua are paddled to express their mana.
Small utilitarian waka are generally plain and unornamented. Superior canoes waka taua in particular, are highly carved. Waka taua are no longer used in warfare but mostly for ceremonial purposes.

Punt
A punt is a flat-bottomed boat with a square-cut bow, planned for use in small rivers or other shallow water. Punting refers to boating in a punt; the punter normally propels the punt by pushing beside the river bed with a pole.
Punts were initially built as cargo boats or platforms for fowling and angling but in modern times their use is almost wholly confined to pleasure trips on the rivers in the university towns of Oxford and Cambridge in England and races at a few summer regattas on the Thames.
A customary river punt differs from many other types of wooden boat in that it has no keel, stem or sternpost. In its place it is built rather like a ladder with the main structure being two side panels connected by a series of 4 in (10 cm) cross planks, known as "treads", spaced about 1 foot (30 cm) apart.
The first punts are traditionally linked with the River Thames in England and were built as small cargo boats or platforms for fishermen. Pleasure punts — particularly built for recreation — became popular on the Thames between 1840 and 1860. Some other boats have a similar shape to a traditional punt — for example the Optimist training dinghy or the air boats used in the Everglades — but they are normally built with a box construction instead of the open ladder-like design of a traditional Thames pleasure punt.

Pirogue
A pirogue is a small, flat-botomed boat of a design associated mainly with West African fishermen and the Cajuns of the Louisiana marsh. These boats are not typically intended for over-night travel but are light and small sufficient to be easily taken onto land. The design also allows the pirogue to move through very shallow water and be simply turned over to drain any water that may get into the boat. The pirogue's motion comes from paddles that contain one blade (as opposed to a kayak paddle, which has two). It can also be punted with a pole in low water.
There is not one pirogue plan, are several. Besides small pirogues as seen on the picture, there are also pirogues that can hold up to ten men with paddles and also characteristic a main sail. These are not planned (and should not be used) for open waters. They are only (and best) used close to shore.

Lifeboat
A lifeboat is a rigid or inflatable boat planned to save the lives of people in trouble at sea. The term has somewhat special meanings in British and American usage. The British usage emphasizes particular vessels kept in harbor or near a harbor, often manned by volunteers, considered to quickly reach a ship in trouble. The term "lifeboat" in American usage normally refers to rigid or inflatable vessels accepted by larger ships to allow passengers and crew to escape in an emergency.
The first boat expert as a lifeboat was tested on the River Tyne on January 29, 1790. William would have and Lionel Lufkin both claim to be the inventor of the first lifeboat. One example of an early lifeboat was the Land guard Fort Lifeboat of 1821, considered by Richard Hall Gower.
In U.S. waters, rescue-at-sea is part of the duty of the United States Coast Guard, which employs its multipurpose ships and aircraft in this role. The Coast Guard is also responsible for making sure that the proper type and number of lifeboats (American usage) is available and kept in good repair on any large ship. "Lifeboat drills" are a division of a cruise experience.

Houseboat
A houseboat is a boat that has been planned or modified to be used primarily as a human dwelling. Some houseboats are not powered, because they are frequently moored, kept stationary at a fixed point.
Houseboats are common as everlasting dwellings in Southeast Asia; in some other areas, they may serve more regularly as secondary or vacation homes or for tourism.
Australia
In Australia, especially on the Murray River and the sunny coastline of Queensland, there are many motorized, pontoon-based houseboats with two or more bedrooms; some of these houseboats have levels or storey. Some are privately own as either a primary house or a holiday shack. Many are also available for hire (rent) as self-driven holiday purpose with accommodation for four to perhaps a dozen persons. Many males enjoy meeting together to fish and drink alcohol in the safe passages of the Coomera River and The Great Sandy Straits near the World's largest sand island - Fraser Island. A famous cruise destination for Queensland house boaters is the Isle of Barry - a unique, peaceful location sought by many, but only found by a dedicated few.
Europe
In Europe, some of the supreme and costliest examples of houseboats can be seen along the canals of Amsterdam (in the Netherlands), which even has houseboat hotels. Houseboats are very luxurious nowadays in Amsterdam because of the limited number of moorings; this expense has reduced the likelihood that the about 2,400 families that live on the inner waters of Amsterdam will find themselves confronted by new neighbor boats.
India
In India, houseboats are frequent on the backwaters of Kerala; see below, and on the Dal Lake near Srinagar in Jammu and Kashmir.

Fireboat
A fireboat is a paying attention watercraft, often similar to a tugboat, with pumps and nozzles planned for fighting shoreline and shipboard fires. They are mostly useful for fighting fires on docks and shore side warehouses as they can directly attack fires in the supporting underpinnings of these structures. They also have an countless supply of water available, pumping straight from the harbor and can be used to assist shore based firefighters when other water is in low supply or is unavailable, for example, due to earthquake breakage of water mains, as happened in San Francisco due to the 1989 Loma Pieta earthquake.
Modern fireboats are competent of pumping tens of thousands of gallons of water per minute. The most technically advanced of these is Fire Boat #2 of the Los Angeles Fire Department, the Warner Lawrence, with the capability to pump up to 38,000 US gallons per minute (2 m³/s) and up to 400 feet (120 m) in the air.
Fireboats are most frequently seen by the public when welcoming a fleet or historical ships with a display of their water moving capabilities, throwing large arcs of water in every direction.
