System Software:
System Software includes the Operating System and all the
utilities that enable the computer to function.
System software is a term referring to any computer software
which manages and controls the hardware so that application
software can perform a task.
Example:
Operating Systems, Compiler, Interpreter.

Application Software:
Application Software includes programs that do real work for
User.
Example:
Word Processor, Spreadsheet and Database Management
System, Payroll systems, Inventory Control, Manage student
database, etc.,

Operating System:
• Operating System is a software, which makes a computer to
actually work.
• It is the software the enables all the programs we use.
• The OS organizes and controls the hardware.
• OS acts as an interface between the application programs and
the machine hardware.
• Examples: DOS, Windows, Linux, Unix and Mac OS, etc.

Machine Language
The only language understood by a
computer is machine language.
Each computer had its own machine
language, which was made of
streams of 0s and 1s.

Low Level Language
Programming language which is machine
dependent(Hardware) is known as Low level
language. Their prime function is to
operate, manage and manipulate the
computing hardware and components.
Example: Machine language, Assemble
language

Programming language having
features of both High level
language and low level language
is known as Middle level
language.
Example: C, C++
Middle Level Language

Source Code and Object Code
• A program written in a Programming
language is called source code.
• The programs are translated into
machine language by interpreters or
compilers.
• The resulting machine language code is
known as object code.
