Careers in Information Technology

By Shyamala Elango


The study of computation and computers is a broad and rapidly changing discipline. In this technological era, almost everybody’s life is affected by computers and technology in some way.
Information Technology (IT) is the application of computers and telecommunications equipment to store, retrieve, transmit and manipulate data, often in the context of a business or other enterprise. It is humanly impossible to learn everything about computers and computing, so it is better to concentrate on any particular aspect of your interest.

Factors Differentiating Various Computing Degrees

  • Professional accreditations
  • Department specialisations
  • Balance between theory and practical in course study.

Educational Requirements

A Bachelor of Information Technology (BIT, B.Tech or BE) is an undergraduate academic degree that generally requires three to five years of study. A degree in computer science differs from IT in a way that computer science degree can be expected to concentrate on the scientific aspects of computing, while a degree in information technology can be expected to concentrate on the business and communication applications of computing. A strong background in the technical fundamentals of computer science and programming languages like Java, Microsoft.NET, and C++ are obviously important for success in the field. But a creative brain and an ambition to stay updated on the newest advances in the field are also key, according to recruiters and IT employees.

Career Prospects in Information Technology

Information Technology (IT) is a broad field that encompasses many careers, including computer programming, technical support and systems analysis. While educational requirements vary according to career objectives, most jobs in Information Technology require at least a bachelor’s degree.

Applications developer

Applications developer translates software requirements into workable programming code and maintains and develops programmes for use in business. Most will specialise in a specific development field – such as mobile phone applications, accounting software, office suites or graphics software – and will have in-depth knowledge of at least one computer language. The principal function of an applications developer is to make computers perform specific tasks, based on the client’s specifications.

IT consultant

An IT consultant works in partnership with clients, advising them how to use information technology in order to meet their business objectives or overcome problems. They work to improve the structure and efficiency of IT systems in various organisations. IT consultants may be used to provide strategic guidance to clients with regard to technology, IT infrastructures and enabling major business processes through enhancements to IT.

Database administrator

A database administrator (DBA) is responsible for the performance, integrity and security of a database. They will also be involved in the planning and development of the database as well as troubleshooting any issues on behalf of the users. DBA roles vary depending on the type of database, the processes they administer and the capabilities of the database management system (DBMS) in use.

Network engineer

Network engineers are responsible for implementing, maintaining, supporting, developing and, in some cases designing communication networks within an organisation or between organisations. They will ensure the integrity of high availability network infrastructure in order to provide maximum performance for their users.

Systems analyst

A systems analyst uses computers and related systems to design new IT solutions, modify, enhance or adapt existing systems and integrate new features or improvements, all with the aim of improving business efficiency and productivity. They must possess a high level of technical expertise and clear insights into current business practices.

Web designer

Web designers plan, create and code web pages, using both non-technical and technical skills to produce websites that fit the customer’s requirements. Web designers might also be responsible for the maintenance of an existing site. Web developing is sometimes confused with web designing. Web developing is a more specialist role, focusing on the back-end development of a website and will incorporate, among other things, the creation of highly complex search functions.

Systems developer

Systems developers maintain, audit and improve organisational support systems by working on the internal operations of computers, using existing systems or incorporating new technologies to meet particular needs, often as advised by a systems analyst or architect. They test both hard and software systems, and diagnose and resolve system faults.

The work done in the computer systems design and related services industry is varied and often on the cutting edge of technology. Overall, employment in this industry has grown rapidly in recent years and is projected to continue to do so. As technology continues to evolve with each passing day, the nature of the Information Technology industry continues to change as well, with new types of career paths constantly emerging.
