4. SOFTWARE
• Software is a collection of computer programs and related data that provide the instruction
for telling a computer what to do and how to do it. A software is an interface between user
and computer. It is a set of instructions, programs that are used to give command to
hardware. It is responsible for controlling, integrating and managing the hardware
components of a computer system and for accomplishing specific tasks.
6. SYSTEM SOFTWARE
• System software consists of several programs, which are directly responsible for controlling,
integrating and managing the individual hardware components of a computer system.
• It also provides the interface between the user and component of the computer.
• The purpose of system software is to insulate the applications programmer as much as possible
from the detail of the particular complex computer being used.
• Depending on the functionality, the system software can be further divided into two major
categories; system management program and developing software.
7. APPLICATION SOFTWARE
• Application software is a program or group of programs designed for end
users. These programs are divided into two classes: system software and
application software. While system software consists of low-level programs
that interact with computers at a basic level, application software resides
above system software and includes applications such as database programs,
word processors and spreadsheets. Application software may be bundled
with system software or published alone
