Information technology is the study of electronic equipment, particularly computers in the collection and storing, and calling information. Over the years, information technology has expanded its area of application. Nowadays we can see the use of IT in each and every field possible.
We use our phones, laptops, and computers, most of the time being unaware of the fact that we are using almost all possible uses of IT. a few years ago, no one would have imagined that IT will take such a leap in the following years.
But, it happened and today, as the computer scientists and software experts say, we are living in an era of information technology where even the smallest of atoms work on the principles of IT. Learn more about definition and examples of information technology from the link.
Importance and Benefits of IT
It's been claimed that data is what drives the world's industries. That may be a stretch, but few organizations, big or small, can stay competitive without the ability to collect data and transform it into actionable information. IT enables the development, processing, analysis, interchange, storage, and security of data.
The following are the few business practices that use IT and data processing, showing how important it is:
Product creation and design
Marketing and market research
Sales and invoicing,
Customer development and retention,
Accounting and taxes,
Human resources and payroll,
Regulatory compliance and testing
Computing has pervaded virtually every aspect of business, as well as much of our personal life. Another reason for IT's importance is the computer's ubiquity, often known as pervasive computing. Personal computers (PCs) and servers are no longer the only computing equipment available.
Phones, tablets, computers, gaming consoles, and even doorbells, thermostats, vacuums, and numerous household appliances are all used by most companies and individuals nowadays. Almost all of these gadgets are connected to the internet of things (IoT), connected to the internet which connects billions of devices across the world.

Benefits of IT
With the progress of technology, one may now access the company's system from any location. The authority does not have to be confined to the office. They can even submit their work from the comfort of their own homes. Without the individual being physically present in the workplace, easy access to the system has undoubtedly boosted productivity.
IT specialists are in high demand in a variety of sectors. The demand creates a huge opportunity for IT experts to learn more about the subject and demonstrate their abilities. Computer programming, system analysis, testing, software and hardware development, web application design, and other IT jobs are available.
Teachers and educational institutions are employing cutting-edge technology to educate their students. Students benefit from having access to a computer with an internet connection since it allows them to learn new things and grasp themes more readily.

Major Applications of IT
IT is a term that refers to the use of computers and telecommunications equipment to analyze, save, retrieve, send, and alter data or information in the context of a business or other enterprise.
People utilize computers in innovative ways every day. Computers and other electronic gadgets have become cheaper in recent years. They continue to become increasingly powerful and user-friendly as information-processing tools.
Humans are growing increasingly reliant on IT-enabled gadgets to do simple activities such as memorizing phone numbers to sophisticated duties such as operating a combat plane. Information technology is used in nearly every area of our lives. The following are a few of the most important:
Science and Engineering
Computers and other microprocessor-controlled technologies are nearly completely responsible for scientific development in disciplines like biotechnology. (Read about Nanotechnology applications in Biology)
Meteorologists use supercomputers to forecast future weather by combining observations of meteorological conditions from a variety of sources, a mathematical description of atmospheric dynamics, and geographic data.
In several sectors, computer-aided design (CAD) and computer-aided manufacturing (CAM) systems have resulted in better products, particularly if designs are highly precise. Engineers may use computer algorithms to assess plans for large buildings like power plants and space stations.
E-government refers to the use of computers to manage transactions and governmental services offered to individuals in the state rather than conventional techniques such as paper or traveling from one department to another.
The computerization of government activities makes it simpler to monitor and audit government operations, as well as making the administration more responsive to societal requirements. It also helps to bridge the gap between the government and the general public.
Touch-screen kiosks, for example, assist in distributing information on property records, picture identification cards, outstanding bills, and other topics, allowing even illiterate individuals to make better judgments. India is the world leader in the efficient use of information technology in elections.
Providing learners with electronic content via the most accessible channels and via the use of current electronic devices such as computers. In most elementary schools across the world, computer education is a required study.
Students are increasingly dependent on electronic sources of knowledge rather than physical libraries as more material is digitized every day and made available to anybody in the world via the internet.
The use of graphics, animations, videos, presentations, and e-learning to supplement conventional approaches has also changed instructional practices.

E-commerce is an information technology application that benefits businesses by increasing profits and gaining access to new markets on a big scale, while also benefiting consumers by increasing access to services and commodities.
Most major corporations store all of their employees' employment records in huge databases that are controlled by computer systems. Billing clients, monitoring payments received and payments to be made, and tracking supplies needed and products manufactured, stored, transported, and sold all employ similar programs and databases.
In reality, almost all of the information that businesses require is obtained via the use of computers and information technology. Almost the majority of the world's financial transactions are conducted electronically. Newer technologies in different areas, such as e-commerce startups, have made it possible for nearly anybody to do ordinary financial transactions while on the go.
Moreover, Many companies have replaced cash registers with point-of-sale (POS) terminals on a smaller scale. When each item is sold, these POS terminals not only generate a sales receipt for the consumer, but also send information to a computer database to keep track of what's in stock and what needs to be bought. In today's factories, computers have also become increasingly crucial.
Hot, heavy, or hazardous activities are now performed by computer-controlled robots. Boredom or weariness can contribute to low-quality labor when robots are utilized to do routine, repetitive activities.
By giving expert sites in many fields of medicine, medical consultations without having to visit a doctor's office, and illness information.
A scanner, for example, uses computerized axial tomography (CAT) or magnetic resonance imaging to acquire a sequence of images of the body (MRI). The images are then stitched together by a computer to create detailed three-dimensional images of the body's organs.
Furthermore, the MRI generates pictures that depict changes in body chemistry and blood flow. The majority of essential life support equipment is programmed to react in split seconds to changes in the patient's state, decreasing reaction time and the danger of human mistakes. Robotic surgery, for example, is a new concept that allows surgeons to operate from afar.

Most people's lifestyles have altered as a result of technology. Games, streaming music and video, digital television broadcasts, satellite radio, animated movies, and other forms of entertainment have emerged as a result of the convergence of various technologies.
These can be accessed via mobile phones, PDAs, notebook computers, or on television via cable or wirelessly using newer-generation WiFi, CDMA, or GPRS technologies.
