3. Information Systems

There are five main components to an information system: hardware, software, database, network, and people.

One of the primary purposes of information systems as one of the branches of computer science is to help organizations gather data. 

Consequently, the data available is used to make informed decisions about how best to allocate resources. 

Information technology has led to an explosion in the quantity and variety of data held by businesses both large and small. 

To successfully manage this influx, sophisticated computer processing methods must be employed. 

These include versatile software application platforms that allow for quick adaptation to changing business needs. 

Further, robust databases containing all relevant customer-collected information policies are used.


  • Information systems play a key role in modern business operations, from accounting to customer service
  • Modern information systems provide organizations with the ability to effectively manage operations and data
  • A well-designed information system can help reduce costs and improve productivity


  • Information systems failures can have significant financial consequences for organizations
  • If not implemented correctly, poorly designed or dysfunctional information systems can lead to chaos and loss of data
  • Computer viruses and other cyber threats continue to increase in severity and frequency
  • Complexity and cost of upgrading information systems

Career prospects

  • Information systems technician
  • Database administrator
  • Business analyst
  • Information systems manager
  • Information security analyst
  • Cybersecurity analyst

4. Information Technology (IT)

Computers can do amazing things, from allowing us to fly through the air in aircraft and explore new parts of our world, to creating incredible works of art. 

Information technology is a field that focuses on finding solutions to problems by using computers. It deals with how we use computers and digital technologies to create, store, share, manage and secure information. 

It encompasses everything from designing databases to developing user interfaces for computer systems. 

And it’s not just organizations who need professionals in this area, individuals are increasingly reliant on the effective use of information technology throughout their lives. 

The use range from managing finances and communication to keeping abreast of global events and navigating the Internet. 

Computers have revolutionized our lives in so many ways and information technology has been at the forefront of that change, enabling us to do things we never thought possible.

5. Software Engineering

Software engineering as one of the five branches of computer science deals with creating, testing, and maintaining software. 

The process can be divided into five steps: designing, testing, executing/operating, monitoring, and controlling. 

Each step has its own set of skills that need to be mastered to succeed as a software engineer. 

Designing software involves coming up with an idea for a program or system and then turning it Into something that users will use. 

Testing aims to detect any deficiencies during development so that they can be fixed immediately before the program is released to the public. 

Execution/operating makes sure the program functions properly under normal conditions. 

Monitoring and controlling provide feedback on performance statistics relating to how well the program performs both now and historically (to ensure trending). 

This requires strong programming skills and knowledge of design patterns, automation tools, and architecture principles, among other aspects of software development.
