What is It Industry? And Overview of It Industry

  1. IT Industry Overview:

The Information Technology (IT) industry is one of the largest industries in the world. This industry provides services and solutions to businesses around the globe. The global market size of this industry was estimated at US$ 2.8 trillion in 2016. The industry is expected to reach US$ 4.6 trillion by 2025

2. IT Industry Structure:

There are three primary segments in the IT industry: hardware, software, and services. Each segment consists of subsegments. The structure of the IT industry is shown below.

3. IT Industry Trends:

 The following trends are likely to impact the IT industry in the coming years:

 • Cloud Computing:

Cloud computing refers to using remote servers hosted on the Internet rather than local servers. The cloud server is accessed through the Internet, and data is stored remotely. The advantage of cloud computing is that users can access their files from any device connected to the Internet.

Cloud computing is a service delivery model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model enables businesses to efficiently scale their infrastructure needs depending on their application demand without investing in hardware facilities, software licenses, data center space, and IT staff.

Mobile Application Development:

Mobile apps are becoming increasingly popular, and they are expected to continue to grow exponentially in the coming years. According to Gartner, mobile app downloads will reach 1 trillion by 2017. With this increase comes the need for developers to create apps that work across multiple devices and operating systems. As a result, mobile app development is becoming a highly competitive field.

Big Data Analytics:

Big data analytics refers to the analysis of large amounts of data sets generated through various sources. The term big data was coined in 2008 by Google CEO Eric Schmidt while he was speaking at the International World Wide Web Conference. He stated that “big data” is data sets so large and complex that traditional database management tools are inadequate.

Internet of Things:

The Internet of Things is a phrase used to describe the idea of connecting every device to the Internet. It focuses on the idea of embedding computers within everyday items using sensors and actuators to collect data and control aspects of those items. The IoT market is divided into three main segments including smart home, industrial automation, and consumer electronics.

The Internet of things (IoT) is a network of physical objects—devices, vehicles, buildings, appliances, tools, medical devices, etc.—embedded with electronics, software, sensors, actuators, and connectivity to enable these objects to exchange data with the manufacturer, operator, occupant, and/or another connected device through various networks. IoT enables smart homes, smart cities, smart grid, and many other applications.

 1. Smart Home:

Smart home refers to the concept of using technology to improve the efficiency and convenience of everyday life at home. This may involve connecting the different devices in the house to the internet and allowing users to control them remotely.

 2. Smart Cities:

A smart city is a planned community that uses Information Technology (IT) to enhance the quality of life of its residents. Smart cities are linked together using the Internet of Things (IoT). They collect data from citizens, businesses, government agencies, and other organizations and share this data among themselves and with private sector partners.

 3. Smart Grid:

Smart grids are a type of electrical grid that uses advanced metering infrastructure (AMI) and communications technologies to allow consumers to manage their electricity usage and reduce energy waste. The smart grid is capable of delivering electricity where and when needed. It allows utilities to operate more efficiently and reduces costs by reducing peak demand, increasing renewable generation, and improving response time during emergencies.

IT Industry jobs and sectors:

Computer Science:

Computer science is the study of computation and its applications. This field involves the design of computer hardware and software, including microprocessors, operating systems, databases, networking equipment, web servers, and many other types of computers. Computer scientists work at all levels of the computing industry, from individual programmers writing code to large corporations developing entire computer systems.

Software Engineering:

Software engineering is the application of scientific methods to create reliable software. Software engineers apply their knowledge of mathematics, physics, statistics, psychology, artificial intelligence, human factors, project management, and various other fields to write programs. They may specialize in certain areas of programming, such as algorithms, data structures, object-oriented analysis, and design, or user interface design.


Network administrators manage networks and network devices, such as routers, switches, firewalls, gateways, and modems. A network administrator might configure network settings, troubleshoot problems, install patches, and monitor network performance. Network administrators often work for Internet service providers, telecommunications companies, government agencies, businesses, educational institutions, and individuals.

Web Development:

Web developers develop websites using HTML, CSS, JavaScript, and other technologies. Most web developers focus on client-side technologies, such as JavaScript, XML, and XHTML. However, some developers specialize in server-side technologies, such as MySQL, PHP, and ColdFusion. The most common type of web developer works for a company that provides web development services. Other web developers work independently.

Desktop Application Development:

Desktop applications are programs designed to perform specific tasks. They are usually used for business purposes. Businesses often hire professional programmers to write custom desktop applications.


The conclusion is that the IT industry is the only employment sector that is providing huge pay to its employees, it is stressful at some levels but if one like his/her own profession then nothing appears like a problem.

Nowadays IT industry has expanded a lot and brought out so many changes in society in terms of technology and many impossible things once became possible now, for example, artificial intelligence came into existence, and the metaverse is almost in the stage of its implementation so one should aware of all these things as software engineers are really needed for the research and development in the society.
