Information technology is the practical application of machines to collect, manage, transmit, and analyze data or information within a network environment. It typically is used in the context of organizational business processes instead of pure entertainment or personal technologies. IT is currently considered a subset of communication and information technology. The three main branches of IT are computer science, information technology, and telecommunications engineering.
Computer science deals with the design, development, and implementation of computers, their components, operating systems, peripherals, and network infrastructures. Areas for computer science include software engineering, virtualization, networking, software applications, and desktop technology. Information technology deals mainly with the transfer of information such as documents, images, data, and voice through networks. Areas for information technology include computer systems, office automation, internetworking, multimedia, mobile devices, multimedia systems, and networking.
Computer systems provide how users access stored data and operate programs. Networks are how various computers communicate with one another and with the operating system. Enterprise systems are those networks and servers used by larger companies and organizations. An enterprise system can consist of servers, desktops, storage appliances, routers, virtualization equipment, application software, network hardware, operating systems, memory, and software applications.
Decision-making refers to the process of formulating an action based on information or facts. It can involve several steps such as developing a product concept, collecting data and information, formulating a business case, analyzing the results, determining priorities and issues, implementing the process, monitoring and controlling the process, reviewing the results, and finally accepting the results and acting accordingly. Organizations must undertake this activity at least once a week. On the other hand, manufacturing and industrial processes entail the production of physical items such as products, raw materials, finished goods, and services. It involves activities such as making, creating, and delivering goods and services. Manufacturing information technology also includes production management, material handling, production control, production optimization, quality assurance, packaging, inventory, distribution, customer service, financial and accounting systems, and human resources.
Information technology includes computer networks, desktop and laptop machines, personal computers, document readers, personal digital assistants (PDAs), wireless computers, webcams, video display equipment, networking equipment, software applications, desktop and laptop computers, digital imaging devices, digital signature, desktop and laptop backup, network vulnerability assessment, application security, network connectivity, computer systems support, computer systems manufacture, computer software, networking hardware, and information technology training. Organizations use information technology to transfer, receive, distribute, and make available data, audio, visual, and speech information of various types to their employees, customers, and customers. They also use it for interactive learning, employee self-service, development of new applications, maintenance, support, business strategy, and business effectiveness. Organizations rely on information technology for developing, deploying, managing, protecting, and supporting information networks.
One of the major activities of IT is data storage, processing, and transmission. It deals with the management of large amounts of data, either within a network or between computers. Data can be stored in computers, external hard drives, external laptop drives, thumb drives, USB pens, compact discs, or any other media. Data transmission converts the information into actual words, pictures, or other forms of presentation. The data storage, processing, and transmission are done through networks and can be either active or passive.
