What is Software?

Software is a collection of instructions or programs that tell a computer or other electronic device what to do. Here we have shared what is software, its meaning, definition, and types.

What is Software?

Software refers to a collection of computer programs, instructions, and data that are used to perform specific tasks on a computer or other electronic devices. The software can be thought of as the “brain” of a computer, as it controls and directs the computer’s hardware to perform tasks such as processing data, displaying graphics, and communicating with other devices.

The software can be developed for a wide range of purposes, from simple applications such as text editors and web browsers to complex systems such as operating systems and enterprise resource planning (ERP) softwares.

S/W can be created using programming languages such as C++, Python, and Java, and can be designed to run on a variety of platforms including desktop computers, mobile devices, and servers.

S/W is an essential component of modern technology and has revolutionized the way we live, work, and communicate. The development and use of s/w have enabled significant advancements in fields such as medicine, science, finance, and entertainment.

Software Meaning

The term “software” is derived from the combination of two words: “soft” and “ware”. “Soft” refers to something that can be easily molded or changed, while “ware” is short for “hardware” and refers to the physical components of a computer system.

Therefore, “software” literally means something that is not a physical component of a computer system, but rather a set of instructions or programs that can be easily modified or changed to perform various tasks and functions on a computer.

Definition of Software

Here are some definitions of software by notable authors:

  • “Software is instructions (computer programs) that when executed provide desired features, function, and performance.
    • It is a data structure that enables programs to adequately manipulate information.
    • It is documents that describe the operation and use of the programs. – Pressman
  • Computer programs and associated documentation. Software products may be developed for a particular customer or may be developed for a general market. – Sommerville
  • “Software is a set of instructions that tell a computer what to do.” – William Stallings
  • “Software is the non-tangible component of a computer system, consisting of encoded computer instructions, in contrast to the physical hardware from which the system is built.” – Ian Sommerville
  • “Software is a collection of programs, data, and instructions that tell a computer how to perform specific tasks.” – John R. Levine
  • “Software is a general term for the various kinds of programs used to operate computers and related devices.” – Richard Stallman
  • “Software refers to a set of instructions that tell a computer what to do and how to do it.” – Peter Norton
  • Software Engineering is the establishment and use of sound engineering principles in order to obtain economical software that is reliable and works efficiently on real machines. – Fritz Bauer (NAU69)

SDLC stands for Software Development Life Cycle. It is a process used in S/W engineering to design, develop, and maintain S/W. The SDLC process typically includes the following phases:

  • Requirements gathering
  • Design
  • Implementation
  • Testing
  • Deployment
  • Maintenance

Requirements gathering: In this phase, the requirements for the software are gathered and analyzed to ensure that the s/w meets the needs of the users.

Design: S/W is designed based on the requirements gathered in the previous phase. The design includes the architecture, data structures, user interface, and other components of the s/w.

Implementation: In this phase, the s/w is actually built or coded using the design specifications.

Testing: In this phase, the s/w is tested for bugs, errors, and other issues to ensure that it meets the requirements and specifications.

Deployment: In this phase, the s/w is deployed to the users or clients.

Maintenance: In this phase, the s/w is monitored and updated to fix any issues that arise, and to keep it up-to-date with new requirements and technologies.

The SDLC process provides a structured approach to s/w development, ensuring that software is developed efficiently, effectively, and with high quality.

22. What is antivirus software?

Antivirus software is a program designed to prevent, detect, and remove malicious software (malware) from a computer or network. Malware includes viruses, Trojans, worms, spyware, and other malicious programs that can harm the computer or steal sensitive information.

Antivirus s/w typically works by scanning the computer’s files and memory for known patterns of malicious code. If it detects a malware, it may either remove the malware automatically or prompt the user to take action.

It may also provide other features, such as real-time protection, firewall protection, email filtering, and web protection, to help prevent malware infections.

It is important to keep antivirus s/w up-to-date with the latest virus definitions to ensure it can detect and remove the latest threats.
