Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (vertical takeoff and landing) aircraft cannot perform.
The word helicopter is adapted from the French language hélicoptère, coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix (ἕλιξ) "helix, spiral, whirl, convolution" and pteron (πτερόν) "wing". English-language nicknames for helicopter include "chopper", "copter", "helo", "heli", and "whirlybird".
Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936. Some helicopters reached limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it is the single main rotor with anti-torque tail rotor configuration that has become the most common helicopter configuration. Tandem rotor helicopters are also in widespread use due to their greater payload capacity. Coaxial helicopters, tiltrotor aircraft, and compound helicopters are all flying today. Quadcopter helicopters pioneered as early as 1907 in France, and other types of multicopter have been developed for specialized applications such as unmanned drones.

Senior management
Senior management, executive management, or management team is generally a team of individuals at the highest level of organizational management who have the day-to-day responsibilities of managing a company or corporation. They hold specific executive powers conferred onto them with and by authority of the board of directors and/or the shareholders. There are most often higher levels of responsibility, such as a board of directors and those who own the company (shareholders), but they focus on managing the senior or executive management instead of the day-to-day activities of the business. The executive management typically consists of the heads of the firm's product and/or geographic units and of functional executives such as the chief financial officer, the chief operating officer, and the chief strategy officer. In Project Management, senior management is responsible for authorising the funding of projects.
They are sometimes referred to, within corporations, as executive management, top management, upper management, higher management, or simply seniors.
Commodore SX-64
The Commodore SX-64, also known as the Executive 64, or VIP-64 in Europe, is a portable, briefcase/suitcase-size "luggable" version of the popular Commodore 64 home computer and holds the distinction of being the first full-color portable computer.
The SX-64 features a built-in five-inch composite monitor and a built-in 1541 floppy drive. It weighs 10.5 kg (23lb). The machine is carried by its sturdy handle, which doubles as an adjustable stand. It was announced in January 1983 and released a year later, at US$ 995 (about $2,250 in 2014).
Description
Aside from its built-in features and different form factor, there are several other differences between the SX-64 and the regular C64. The default screen color is changed to blue text on a white background for improved readability on the smaller screen. This can cause compatibility problems with programs that assume the C64's default blue background. The default device for load and save operations is changed to the floppy drive.

Service (economics)
In economics, a service is an intangible commodity. That is, services are an example of intangible economic goods.
Service provision is often an economic activity where the buyer does not generally, except by exclusive contract, obtain exclusive ownership of the thing purchased. The benefits of such a service, if priced, are held to be self-evident in the buyer's willingness to pay for it. Public services are those, that society (nation state, fiscal union, regional) as a whole pays for, through taxes and other means.
By composing and orchestrating the appropriate level of resources, skill, ingenuity, and experience for effecting specific benefits for service consumers, service providers participate in an economy without the restrictions of carrying inventory (stock) or the need to concern themselves with bulky raw materials. On the other hand, their investment in expertise does require consistent service marketing and upgrading in the face of competition.
