Types:

• System Software

     System Software Provides Core Functions such as Operating Systems , Disk Management , Utilities , Hardware Management and Other Operational Necessities.
  

• Programming Software

     Programming Software to Give Programmers Tools such as Text Editors , Compilers , Linkers , Debuggers and Other Code Creation Tools.

• Application Software

     Application Software ( Application or App ) Help Users Perform Tasks. Office Productivity Suites , Data Management Software , Media Players and Security Programs are Examples. Applications Also Refers to Web And Mobile Applications Like Those Used to Shop on Amazon.com , Socialize with Facebook or Post Pictures to Instagram.
  A possible Fourth Type is Embedded Software. Embedded Systems Software is Used to Control Machines And Devices Not Typically Considered Computers — Telecommunications Networks , Cars , Industrial Robots and More. These Devices , and Their Software , can be Connected as Part of The Internet of Things ( IoT ). Software Development is Primarily Conducted By Programmers , Software Engineers and Software Developers. These Roles Interact and Overlap , and The Dynamics Between Them Vary Greatly Across Development Departments and Communities.

• Programmers or Coders

    Programmers or Coders , Write Source Code to Program Computers for Specific Tasks like Merging DataBases , Processing Online Orders , Routing Communications , Conducting Searches Or Displaying Text and Graphics. Programmers Typically Interpret Instructions from Software Developers and Engineers and Use Programming Languages like Python or Scala to Carry Them Out.

• Software Engineers

    Software Engineers Apply Engineering Principles to Build Software and Systems to Solve Problems. They Use Modeling Language and Other Tools to Devise Solutions that can Often be Applied to Problems in a General Way , as Opposed to Merely Solving For a Specific Instance or Client. Software Engineering Solutions Adhere to The Scientific Method And Must Work in The Real World. Their Responsibility Has Grown As Products have Become Increasingly more Intelligent with The Addition Of Microprocessors , Sensors and Software. Not Only Are More Products Relying on Software For Market Differentiation , But their Software Development Must Be Coordinated With The Product's Mechanical And Electrical Development Also.

• Software Developers

    Software Developers have a Less Formal Role Than Engineers and Can be Closely Involved with Specific Project Areas - Including Writing Code. At the Same Time , They Drive the Overall Software Development Lifecycle - Including Working Across Functional Teams To Transform Requirements Into Features , Managing Development Teams And Processes , And Conducting Software Testing And Maintenance.
