An Overview of Software
• Software is basically categorized into two main types: Systems and
Application Software
• Systems software
• Sets of programs designed to operate, control, and extend processing capabilities of
the computer.
• It runs the computer hardware and application programs.
• Is an interface or buffer between application software and hardware
• Examples: operating system, compilers, interpreters, utility programs
• Application software
• Programs that help users solve particular computing problems
• Most application software programs are OS specific
• Examples: word processing software, payroll software, student record software,
browsers etc.

Layer 1
Types Application Software
• Proprietary
• Owned by companies or an individual who developed it.
• There are restrictions on its use and the source code is
kept a secret
• Designed to solve a unique and specific problem
• In-house
• Development of application software using the
company’s resources
• Contract
• Developed for a particular company
• Off-the-shelf
• An existing software program that can be used without

Personal Use
• The use of information system or a
software to achieve a person goal.
• Think of anything you might want to do on
a computer, and someone has probably
created application software for it.

types of applications that most users have
installed on their computer.
• Examples is using Microsoft word to
complete your final project work.

Workgroup Applications
• A workgroup is a collection of individuals working together on a task.
Many personal applications extend into workgroup applications.
• Workgroup software applications are also referred to as 'collaborative
software,' or 'groupware.'
• There are several categories of workgroup applications, including:
• Electronic communications: applications send messages, documents
and files between people on different computer systems.
• Electronic conferencing : software that makes it possible to have
meetings in real-time without being physically present in the same
location.
• Scheduling and coordination tools: facilitate scheduling meetings and
other group activities.

Enterprise Applications
• An Enterprise is an organization with a large number of employees, typically
distributed over a number of offices located at different geographic locations.
• An enterprise application is therefore a big complex business application.
