E.g;Microsoft Windows,Mac OS X or Linux( kinda operating system)

Application software?
consists of programs designed to make users more productive and, or assist them with personal tasks. It is widely used related to communications such as Web browser.
Web Browser allows users with an Internet connection to access and view Web Pages.

Variety uses of application software..

• to make business activity more efficient
• to assist with grapic and multimedia project
• to support home,personal and educational task
• to facilitate communications
  

Other types of application software...

• word processing software
• spreadsheet software
• database software
• presentation graphics software.

Operating system (OS) (sometimes called the platform) coordinates all activities among computer hardware resources.

Some functions of an operating system...

• start the computer
• manage programs
• provide a user interface
• administer security
• monitor performance
• manage memory
• provide file management and other utilities
• establish an internet connection
• control a network and schedule jobs and configure devices.

Three categories of operating systems..

• stand-alone
• embedded
• network.

Utility programs is a system software that performs maintenance-type tasks (also called utility).

Stand- alone utility programs consists..

• virus
• antivirus program
• spyware
• internet filters
• file compression utility,
• CD/DVD burning software
• personal computer maintenance utility.

System software contrasts with application software, which are programs that enable the end-user to perform specific, productive tasks, such as word processing or image manipulation.

Input and Output

Input
Input is any data and instructions entered into the memory of a computer.An input device is any hardware component that allows users to enter data and instruction into a computer.
E.g;mouse,keyboard,touch screen,digital pen,stylus,graphic tablet,game controller,joystick,bar code reader,magnetic stope card reader,PC video camera and digital video camera.

Other Input Devices

1.Voice Input
Is the process of entering by speaking into a microphone. Voice recognition also called speech recognition,is a computer's capability of distinguishing spoken words. The vocabulary of voice recognition programs can range from two words to millions of words.

Other Output Devices

1.Computer component that produces music, speech, or other sounds. E.g;Speakers, earphones, and earbuds are common devices

2.Voice output
Computer talks to you through speakers on computer.Internet telephony allows you to have conversationover the Internet.

3.FAX

4.Multifunction Peripheral
Is a single device that looks like a copy machine but provides the functionality of a printer,scanner,copy machine, and perhaps a fax machine.

.Data Projector

Conclusion, output and input are very important in computer system because it help to make the users more easier in order to explore the computer..
