Employment is a contract between two parties, one being the employer and the other being the employee. An employee may be defined as: "A person in the service of another under any contract of hire, express or implied, oral or written, where the employer has the power or right to control and direct the employee in the material details of how the work is to be performed." Black's Law Dictionary page 471 (5th ed. 1979).
In a commercial setting, the employer conceives of a productive activity, generally with the intention of generating a profit, and the employee contributes labor to the enterprise, usually in return for payment of wages. Employment also exists in the public, non-profit and household sectors. To the extent that employment or the economic equivalent is not universal, unemployment exists.
An employer is a person or institution that hires employees or workers. Employers offer hourly wages or a salary in exchange for the worker's labor power, depending upon whether the employee is paid by the hour or a set rate per pay period. A salaried employee is typically not paid more for more hours worked than the minimum, whereas wages are paid for all hours worked, including overtime.
Employers include everything from individuals hiring a babysitter to governments and businesses which may hire many thousands of employees. In most western societies, governments are the largest single employers but most of the work force is employed in small and medium businesses in the private sector.

River Water
A river is a natural stream of water, usually freshwater, flowing toward an ocean, a lake, or another stream. In some cases a river flows into the ground or dries up completely before reaching another body of water. Usually larger streams are called rivers while smaller streams are called creeks, brooks, rivulets, rills, and many other terms, but there is no general rule that defines what can be called a river. Sometimes a river is said to be larger than a creek, but this is not always the case.
A river is a component of the hydrological cycle. The water within a river is generally collected from precipitation through surface runoff, groundwater recharge (as seen at baseflow conditions / during periods of lack of precipitation) and release of stored water in natural reservoirs, such as a glacier.
The water in a river is usually confined to a channel, made up of a stream bed between banks. In larger rivers there is also a wider floodplain shaped by flood-waters over-topping the channel. Flood plains may be very wide in relation to the size of the river channel. This distinction between river channel and floodplain can be blurred especially in urban areas where the floodplain of a river channel can become greatly developed by housing and industry.

Video Technology
Video technology was first developed for cathode ray tube television systems, but several new technologies for video display devices have since been invented. Standards for television sets and computer monitors have tended to evolve independently, but advances in computer performance and digital television broadcasting and recording are producing some convergence.
Computers can now display television and film-style video clips and streaming media, encouraged by increased processor speed, storage capacity, and broadband access to the Internet. General-purpose computing hardware can now be used to capture, store, edit, and transmit television and movie content, as opposed to older dedicated analog technologies.
The term video (from Latin: "I see") commonly refers to several storage formats for moving eye pictures: digital video formats, including DVD, QuickTime, and MPEG-4; and analog videotapes, including VHS and Betamax. Video can be recorded and transmitted in various physical media: in magnetic tape when recorded as PAL or NTSC electric signals by video cameras, or in MPEG-4 or DV digital media when recorded by digital cameras.

Mobile Portable Devices
A mobile device (also known as cellphone device, handheld device, handheld computer, "Palmtop" or simply handheld) is a pocket-sized computing device, typically having a display screen with touch input or a miniature keyboard. In the case of the personal digital assistant (PDA) the input and output are combined into a touch-screen interface.
Smartphones and PDAs are popular amongst those who require the assistance and convenience of a conventional computer, in environments where carrying one would not be practical. Enterprise digital assistants can further extend the available functionality for the business user by offering integrated data capture devices like Bar Code, RFID and Smart Card readers.
Mobile devices have wireless capability to connect to the Internet and office/home computer systems. However wireless capability poses a number of security risks. Managing the risks to mobile assets requires knowledge of the threats posed to mobile devices and the vulnerabilities that may allow those threats to be realized.
The Mobile Device Vulnerability Database (MDVD) is an online database for collecting vulnerability and countermeasure information on mobile computing devices and their technologies (Smart phone, personal digital assistant (PDA), Wi-Fi, Bluetooth, WiMAX, VOIP, etc.) with references to all vulnerability and countermeasure information. View all information in the database as well as add vulnerability and countermeasure information on mobile computing hardware and software technologies.

3D Computer Graphics
3D computer graphics (in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.
Despite these differences, 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire-frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, the distinction between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and primarily 3D may use 2D rendering techniques. 3D computer graphics are often referred to as 3D models.
Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences. A 3D model is the mathematical representation of any three-dimensional object (either inanimate or living). A model is not technically a graphic until it is visually displayed. Due to 3D printing, 3D models are not confined to virtual space. A model can be displayed visually as a two-dimensional image through a process called 3D rendering, or used in non-graphical computer simulations and calculations.

Networking process Forum
The Network Processing Forum (NPF) was organized to facilitate and accelerate the development of next-generation networking and telecommunications products based on network processing technologies. The NPF was merged into the Optical Internetworking Forum in June 2006. The NPF produces Hardware, Software, and Benchmark Interoperability Agreements. These agreements enable equipment manufacturers to lower their time to market and development cost by enabling a robust, multi-vendor ecosystem.
It also lowers the total cost of ownership of systems based on their interoperability agreements by enabling investments in test and verification infrastructure as well as enabling competition. The organization was formed to build on the efforts of two former industry groups, the Common Programming Interface Forum (CPIX) and the Common Switch Interface Consortium (CSIX).
Chuck Sannipoli then of IBM was the first chairman of the NPF. Misha Nossik then of Solidum Systems, later acquired by Integrated Device Technology was the second chairman of the NPF. Many of the original meetings were held in the Drake H

Notepad
A laptop (also known as a notebook) is a personal computer designed for mobile use small enough to sit on one's lap. A laptop includes most of the typical components of a typical desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, or a pointing stick) as well as a battery, into a single small and light unit. The rechargeable battery required is charged from an AC/DC adapter (ie, a wll wart) and typically stores enough energy to run the laptop for several hours.
Laptops are usually shaped like a large notebook with thicknesses between 0.7–1.5 inches (18–38 mm) and dimensions ranging from 10x8 inches (27x22cm, 13" display) to 15x11 inches (39x28cm, 17" display) and up. Modern laptops weigh 3 to 12 pounds (1.4 to 5.4 kg); older laptops were usually heavier. Most laptops are designed in the flip form factor to protect the screen and the keyboard when closed. Modern 'tablet' laptops have a complex joint between the keyboard housing and the display, permitting the display panel to twist and then lay flat on the keyboard housing. They usually have a touchscreen display and some include handwriting recognition or graphics drawing capability.
Laptops were originally considered to be "a small niche market" and were thought suitable mostly for "specialized field applications" such as "the military, the Internal Revenue Service, accountants and sales representatives"
