What are the 3 levels of software

Level 1: Runtime. The runtime level deals with specific values and a specific environment from a single execution of the program. … Level 2: Concrete Implementation/Code. … Level 3: Design/Logic: At the level of logic, we consider the abstract specification of each unit of a program.

What do you know about software?

Software is a set of instructions, data or programs used to operate computers and execute specific tasks. It is the opposite of hardware, which describes the physical aspects of a computer. Software is a generic term used to refer to applications, scripts and programs that run on a device.
