Information Technology plays a major role today in our life. IT is the backbone and most important function to run any Organization today.

Following are the major sub domains of Information Technology:

1. Infrastructure
Infrastructure is known to be the systems of hardware and software that facilitate software components to support the delivery of business systems with the help of any IT-enabled procedures.

2. Computing
Computing is a known goal-oriented activity that requires creating computer machinery. It includes studying as well as experimenting with algorithm processing with the development of both hardware and software. Computing encompasses scientific, engineering, and tons of social aspects.

3. Software
The software comprises a set of instructions, data, and programs that operate the computer and execute specific tasks. It is the opposite of hardware which primarily describes the physical aspect of the computer.

4. Networks
Computer networks primarily concern themselves with interconnecting computing devices and exchanging data and resources with one another. These networks use a comprehensive system of rules called communication protocols to transmit information over physical and other wireless technologies.

5. APIs
The full form of API is Application Programming Interface. It deals with any software with a distinctive function. The interface in this aspect can be considered a contract of service between two applications. This defines the method of communicating between the networks through requests and responses.

6. Analytics
Analytics has a catch-all term of variety in different places of business intelligence and applications that relate to these initiatives. The process of analyzing information with the help of a particular domain is known as website analytics, an important aspect of Information Technology.

7. Robotic Process Automation
This IT automation deals with the creation of software and systems to replace any repeatable procedures. This is also responsible for reducing manual intervention. This helps accelerate the delivery of Information Technology infrastructure and applications by processing manual processes automatically that previously required a human touch.

8. Artificial intelligence
This is a simulation of human intelligence that is processed by machines, especially concerning computer systems. The specific AI applications are expert systems, natural language processing, speech recognition, and machine vision.

9. Cloud computing
In layman’s terms, cloud computing is the method of delivery of computing services. This includes server storage alongside databases and networking software analytics and intelligence. This offers faster innovation and flexible resources, and economies of scale.

10. Communications
Communications play a vital role in Information Technology. It is an umbrella that includes any communication device encompassing the segments of television, cellular phones, computer and network hardware, satellite systems, and many more. It also encompasses the other services that are associated with these applications at large.

11. Cybersecurity
Cyber security protects internet-connected systems for hardware and software data from the verge of cyber threats. Individuals and other enterprises, therefore, use the practice to protect themselves against unauthorized access to data centers and other computerized systems.

12. Internet of Things
The Internet of Things or IoT is the collective network of connected devices and the technology that helps make effective communications between the devices and the cloud.

13. Machine Learning
This branch of artificial intelligence and computer science focuses on using data and other algorithms to imitate human learning, thus improving accuracy.

14. Software/Application Development
This development method helps create a computer program with a set of other programs to perform different tasks that a business might require. Starting from the calculation of monthly expenses to scheduling any sales report, application business thereby helps in automating processes and increasing any kind of efficiency.
