Characteristics of Software

Software is a set of instructions or programs that tell a computer what to do. Here are some of the main characteristics of software:

Characteristics of Software

Here are the nature and characteristics of software.

  • Intangible
  • Flexible
  • Scalable
  • Reliable
  • Portable
  • Diverse
  • Interconnected
  • Dynamic
  • Reusability
  • Testability
  • Accuracy


Software is an intangible part of the computer system. It is a non-physical entity that cannot be touched or seen. It exists in the form of code written in a programming language.

Software projects are intangible because managers cannot see progress by looking at the artifact that is being constructed. They rely on others to produce evidence that they can use to review the progress.


Software is highly flexible and can be easily modified or updated to suit changing needs. Unlike hardware, which requires physical changes to be made, software can be updated by simply changing the code.

The extent to which you can modify a system for uses or environments other than those for which it was specifically designed.

Scalable (Characteristics of Software)

The software can be designed to handle a wide range of tasks, from simple calculations to complex data processing. As the needs of the user grow, the software can be expanded to handle the increased workload.

Reliable (Characteristics of Software)

Software is designed to be reliable, providing consistent performance over time. When bugs or errors do occur, they can usually be fixed through updates or patches.

Reliability of software is the ability of a system to perform its required functions under state conditions whenever required-having a long mean time between failures.

Portable (Characteristics of Software)

Software can be easily moved from one computer to another, as long as the destination machine has the necessary software and hardware requirements.

The ease with which you can modify a system to operate in an environment different from that for which it was specifically designed.


There are many different types of software, including operating systems, applications, utilities, and programming tools. Each type of software has its own unique features and functions.


The software can be designed to work with other software, allowing users to build complex systems that perform a wide range of tasks.


Software is constantly evolving, with new updates and features being released on a regular basis. This helps to keep software relevant and up-to-date in a rapidly changing technology landscape.


Reusability of the software is the extent to which and the ease with which you can use parts of a system in other systems.


The degree to which you can unit test and system test a system is the degree to which you can verify that the system meets its requirements.


The degree to which a system, as built, is free from error, especially with respect to quantitative outputs. Accuracy differs from correctness, it is a determination of how well a system does the job it’s built for rather than whether it was built correctly.
