Information technology is the application of computers to make, process, store, retrieve and share all forms of information and data. Information technology has become a significant part of all industries and professions, ranging from business to health information technology. It covers a broad spectrum, with different areas such as business applications, computer engineering, health care informatics, and social networks. IT is most commonly used in the context of enterprise architecture rather than individual or entertainment technology.
The dawn of information technology can be traced back to the year 1960. This marked the introduction of the mainframe computer, the mainframe being an integrated circuit containing multiple transistors and capacitors. The first microprocessor was based on the instruction-order scheduling (OAS) architecture. The mainframe and its systems became very efficient, thanks to the parallel processing capability provided by the microprocessor. After this, the development of mainframe computers and related hardware was accelerated through the development of personal computers.
From the early years of information technology, three widely accepted definitions have been used, each with their own unique definition of what the term information technology actually implies. These are: computer networks, computer software, and hardware. While the computer network refers to how a computer system is networked, a software program refers to the set of instructions that operate a specific piece of hardware. In other words, computer software is used to specify how a computer will perform a particular task.
Computer systems have developed vastly since the early days of information technology, reaching all aspects of society, including government agencies and businesses. Today, computers are included in most every aspect of daily life, from office automation to automobile fleets to healthcare practices. With the rapid growth of computer systems, networks have also developed to support these developments. Businesses have found that they can save thousands of dollars per year by using existing computer systems, and even more by installing state-of-the-art networks for their entire business.
The typical information technology support specialist job involves managing a company’s computer systems, hardware, networking, and data storage needs. An information technology support specialist, like a hardware or software engineer, is responsible for designing, building, and maintaining a company’s computer systems. They typically handle the upgrade or replacement of outdated hardware and for helping companies plan and implement new technologies.\
As the demand for information technology continues to grow, there will be a growing need for IT professionals. As employers try to cut costs, an information technology support specialist position is often seen as a logical choice to meet these labor demands. Many of these professionals begin their work for IT companies by working as a general technician to provide basic computer support to a smaller team of technicians who design and develop the technology used in large-scale companies. As positions of information technology support specialist and information systems manager become more common in the job market, more IT professionals will be required to fill available positions.
