Answer 1

There are two main types of software: systems software and application software.
Systems software includes the programs that are dedicated to managing the computer itself, such as the operating system, file management utilities, and disk operating system (or DOS).
Application software, or simply applications.

front end ,back end and full stack developers are called so bcoz of their knowledge in respective field.
