CHAPTER 4 : PROGRAMS AND APP

Objectives Overview :

· Identify the general categories of programs and apps

· Describe how an operating system interacts with applications and hardware

· Differentiate among the ways you can acquire program and apps

· Identify key features of productivity applications

· Identify the key features of graphics and multimedia applications

Programs, Software and Apps :

· Program – A set of instructions telling a computer what to do

· Software – The programs and other operating information used by a computer. Software can be made up of more than one program. All-encompassing term that is often used in contrast to hardware

· Application – A program or group of programs that is designed for the end user. Application software cannot run on itself but is dependent on system software to execute

v All applications are program, but a program is not necessarily an application. For example, there are always lots of programs running on the background of an operating system, but since they weren’t developed for the end-user, they are not applications.

Operating System :

An operating system is a set of programs that coordinates all the activities among computer or mobile device hardware : -

 Windows

 Linux

 Redhat

 Mac OS

 

Productivity Applications :

With productivity applications, users often : -

ü Create a project

· The difference between Spreadsheet and Database : -

Spreadsheet	Database
Tabulate data and create graphs based on the data	Stored data so that can be retrieved by users
Hold a less amount of data	Hold a large amount of data
Too much data is simply impractical in a single spreadsheet as it becomes more difficult for a person to edit it	Not edited directly by people as there are other applications that are meant to enter new data or modify the contents
