Following are the major sub domains of Information Technology:

1. 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.

2. 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.

3. Platforms
The platform is a hybrid of both hardware and software architecture. It is a foundation based on other applications, processes, and technologies developed. This is the place where software applications are primarily run.

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. Data
Data is a piece of information that has been translated as an efficient form of movement or processing. Considering today’s translation media, data plays a significant role to be converted into a binary digital form. Data can be accepted as both singulars as well as plural subjects.

7. Databases
A database is an organized collection of structured data or information stored electronically in a computer system. It is looked after by the Database Management System (DBMS).

8. Data Synchronization
Data synchronization is a form of embedded middleware that allows the application to update data on two systems simultaneously. This helps the data set to be identical. These services could be run on a variety of transportation methods that will only typically require some application-specific knowledge or notion of the data to be synchronized.

9. Data Storage
This consists of retaining information by using technologically specific developed forms of Information Technology and making it accessible if it deems fit. Data storage refers to recording media and retaining the data using a computer or other devices.

10. 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.

11. Content Delivery
Content delivery is a branch of content distribution, delivery, and content caching. It is a service of copying the pages to a website and geographically dispersed over the server when the page is requested, thus dynamically identifying the serving page content from the closest server.

12. Content Management
Content management comprises templates, procedures, and standard software format that enables marketers and their proxies. These proxies help produce and manage text, graphics, pictures, and audio alongside the video for web landing pages, blogs, and document repositories.

13. Monitoring
It is the process to gather metrics regarding the IT operations with environment hardware and software that will ensure every function is done as expected to support applications and other services.

14. Event Processing
These are computations that perform operations on events when they are being reported in systems that observe or listen to environment-based events. Reading, creating, and transforming are fine examples of event processing.

15. 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.

16. Transaction Processing
Transaction processing is a known processing style typically performed by a large server of computers that supports interactive applications. In transaction processing, work is divided into individual, indivisible operations and other transaction methods.

17. 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.

18. 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.

19. 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.

20. 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.

21. 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.

22. 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.

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

24. Maintenance and Repair
This ensures the product sustainability of a particular function and ensures that it lasts throughout its operational life cycle. This helps the IT professional to handle the products with utmost care and ensure their security.

25. Robotics
This function is made by a bunch of combinations of programming and algorithms that manipulators and actuators remotely control with the help of a control system that facilitates action, processing, and perception with the help of real-time sensors. The goal of robotics is to design machines and make the lives of humans easier.

26. 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.
