Information and communication technology spending in 2005 Information technology (IT) is "the study, design, development, application, implementation, support or management of computer-based information systems, particularly software applications and computer hardware", according to the Information Technology Association of America (ITAA).[1] IT deals with the use of electronic computers and computer software to securely convert, store, protect, process, transmit, input, output, and retrieve information. General information As it pertains to technology, IT spans a wide variety of areas that include but are not limited to things such as Processes, Computer Software, Computer Hardware, Programming Languages, and Data Constructs. In short, anything that renders data, information or perceived knowledge in any visual format whatsoever, via any multimedia distribution mechanism, is considered part of the domain space known as Information Technology (IT). As it pertains to organizations within enterprises, IT represents an operational group that helps solve such problems as those related to data, information and knowledge capture, persistence, processing, brokering, discovery and rendering. Such organizations can be as small as one or two people that can be shared between multiple small business and as large as multi-billion dollar structures that are common in all Fortune 500 enterprises. Today, the term information has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. IT professionals perform a variety of functions (IT Disciplines/Competencies) that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as management and administration of entire systems. Information technology is starting to spread farther than the conventional personal computer and network technology, and more into integrations of other technologies such as the use of cell phones, televisions, automobiles, and more, which is increasing the demand for such jobs. In the recent past, ABET and the ACM have collaborated to form accreditation and curriculum standards[2] for degrees in Information Technology as a distinct field of study separate from both Computer Science and Information Systems. SIGITE[3] is the ACM working group for defining these standards. The Worldwide IT services revenue totaled $763 billion in 2009.[4] It is important to consider the overall value chain in technology development projects, as the challenge for the value creation is increasing with the growing competitiveness between organizations. The concept of value creation through technology is heavily dependent upon the alignment of technology and business strategies. While the value creation for an organization is a network of relationships between internal and external environments, technology plays a role in improving the overall value chain of an organization. However, this increase requires business and technology management to work as a creative, synergistic, and collaborative team instead of a purely mechanistic span of control. Technology can help an organization improve its competitive advantage within the industry in which it resides and generate superior performance at a greater value.

Unix was originally released by Bell Labs to various government and educational institutions. This popularity led to the adaptation of Unix by many start up companies; as a result, Unix helped fuel the growth of the internet in the 1990s. Overview of Linux Linux is a Unix-like computer Operating System (or OS) that uses the Linux kernel. Linux started out as a personal computer system used by individuals, and has since gained the support of several large corporations, such as Sun Microsystems, HP and IBM. It is now used mostly as a server operating system, with some large organizations using an enterprise version for desktops. Linux is a prime example of open-source development, which means that the source code is available freely for anyone to use. The Information Technology Infrastructure Library (ITIL) is a set of concepts and techniques for managing information technology (IT) infrastructure, development, and operations. ITIL® is the most widely accepted approach to IT service management in the world. ITIL provides a cohesive set of best practice, drawn from the public and private sectors internationally. A whole ITIL philosophy has evolved from the guidance contained within the ITIL books and the ITIL professional qualification scheme. Benefits of ITIL: By providing a systematic approach to the management of IT service, ITIL can help an enterprise in the following ways: * reduced costs * improved IT services through the use of proven best practice processes * improved customer satisfaction through a more professional approach to service delivery * standards and guidance * improved productivity * improved use of skills and experience * improved delivery of third party services through the specification of ITIL or ISO 20000 as the standard for service delivery in services procurements. Definition: Business Intelligence (BI) is the ways in which we store and use business information. It encompasses the technologies, applications, and means for collecting, integrating, analyzing, and presentating bsuienss data. Using data that has been stored in a data warehouse, software applications are able to use this data to report past business information as well as predict future business information, including trends, threats, opportunities and patterns. Project Manager Overview A Project Manager is responsible for managing the resources of large projects. For Tech Careers, can mean managing large Software Development projects, Networking projects, IT installations or conversions, or any other function where business and technology needs have to be managed and resources have to be coordinated. The Project Manager is responsible for making sure a project is completed within a certain set of restraints. These restraints usually involve time, money, people and materials. The project must then be completed to a certain level of quality. Project Managers usually use Project Management Software to help keep track of resources and project deliverables (or outputs). This software helps document the project objectives, status, time lines and expected outcomes. Current popular project management software products include: * Microsoft Project * 24Seven Office * OmniPlan * AtTask * * Definition: * IT Governance, or Information Technology Governance, is a subset of Corporate Governance focused on information technology (IT) systems performance and risk management. There is a continual interest in IT governance as a result of compliance initiatives and the knowledge that IT projects can easily get out of control and have a serious effect on the performance of a company. * Definition: * Information security refers to protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. The goals of information security include protecting the confidentiality, integrity and availability of information. Computer Networking Information: Computer Networking Computer Networking is a focus within engineering that deals with communication between computer systems or devices. Computer networking is often considered a sub-discipline of a few areas: telecommunications, computer science, information technology and/or computer engineering.
