Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of data and information. IT forms part of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users. Although humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs. The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several products or services within an economy are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce.[a] Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC — 1450 AD), mechanical (1450—1840), electromechanical (1840—1940), and electronic (1940 to present). Information technology is also a branch of computer science, which can be defined as the overall study of procedure, structure, and the processing of various types of data. As this field continues to evolve across the world, the overall priority and importance has also grown, which is where we begin to see the introduction of computer science-related courses in K-12 education.Business partnering is the development of successful, long term, strategic relationships between customers and suppliers, based on achieving best practice and sustainable competitive advantage. In the business partner model, HR professionals work closely with business leaders and line managers to achieve shared organisational objectives. In practice, the business partner model can be broadened to include members of any business function, for example, Finance, IT, HR, Legal, External Relations, who act as a connector, linking their function with business units to ensure that the technical, or functional, expertise they have to offer is placed within the real and current concerns of the business to create value.
West Yorkshire is a metropolitan and ceremonial county in England. It is an inland and, in relative terms, upland county having eastward-draining valleys while taking in the moors of the Pennines. West Yorkshire came into existence as a metropolitan county in 1974 after the passage of the Local Government Act 1972 and has a population of 2.3 million.
West Yorkshire consists of five metropolitan boroughs (City of Bradford, Calderdale, Kirklees, City of Leeds and City of Wakefield) and is bordered by the counties of Derbyshire to the south, Greater Manchester to the south-west, Lancashire to the west and north-west, North Yorkshire to the north and east, and South Yorkshire to the south and south-east.
Remnants of strong coal, wool and iron ore industries remain in the county, having attracted people over the centuries, and this can be seen in the buildings and architecture. Major railways and two major motorways traverse the county, which also contains Leeds Bradford International Airport.
West Yorkshire includes the West Yorkshire Urban Area, which is the biggest and most built-up urban area within the historic county boundaries of Yorkshire.
