Computer Software Class 8 Computer Lesson.pptx
- 1.
- 2. Today’s Agenda • Introduction •System Software • Operating System • Language Translator • Utility Software • Application Software • Packaged Software • Tailored Software
- 3. • A setof instructions written to instruct the computer to solve a particular problem is called program . • A collection of programs is called Software. • In a computer system, the software is basically a set of instructions or commands that tell a computer what to do. Introduction
- 4.
- 5. 1.System Software • Systemsoftware is software that directly operates the computer hardware and provides the basic functionality to the users as well as to the other software to operate smoothly. • System software basically controls a computer’s internal functioning and also controls hardware devices such as monitors, printers, and storage devices, etc. • Write the functions of system software from book.
- 6. a)Operating System • Itis the main program of a computer system. When the computer system ON it is the first software that loads into the computer's memory. • OS is an integrated set of programs that controls/manages the hardware and software resources. • OS provides an interface to the user, which helps the user to interact with the computer system. • For Example: MS-DOS, WINDOWS, LINUX, MacOS • Write Functions of OS from your book
- 7. Make a tableof 5/5 rows and column
- 8. • On thebasis of the user supported by OS: 1.Single-User Operating System: An operating system that allows a single user to perform just one task at time is called single user operating system. For Example: MS-DOS 2.Multi-User Operating System: An operating system that allows multiple users to use programs that are simultaneously running on a single network server For Example: UNIX, Linux, Windows Types of Operating System
- 9. • On thebasis of interface provided by OS: 1.Character user interface operating system: An operating system that provides user interface that use only alphanumeric characters for input-output operations. For example: MS-DOS 2. Graphical user interface operating system: An Operating System that allows users to give commands using icons, menus and buttons through mouse and keyboard. For example: Linux, Windows, MacOS
- 10. Difference Between CUIand GUI
- 11. Assessment Questions: 1) Whatis Software? 2) List the types of software. 3) What is OS? Give two example. 4) Write 2/2 difference between CUI AND GUI.
- 12. b) Program Translator •Program translators are system software, which converts the instructions prepared by programmers in a programming language into the form of 0s and 1s, which can be interpreted and executed by the computer system. • Program translators are classified into three types: 1.Assembler 2.Interpreter
- 13. 1.Assembler: An assembler isa language translator which is used to translate the program written in Assembly language into machine code.
- 14. 2.Interpreter: An interpreter isa type of system software which translates a program written in a high level language to its equivalent machine level language one instruction at a time. For example: Python, PHP etc.
- 15. 3.Compiler: The language processorthat reads the complete source program written in high-level language as a whole in one go and translates it into machine language is called a Compiler. Example: C, C++, C#.
- 16. Assignment Questions: 1) Whatis Program Translators? 2)Write 2/2 difference between assembler and compiler. 3)Write 2/2 difference between interpreter and compiler.
- 17. 2.Utility Software Utility softwareis a set of programs or software that helps users in system maintenance tasks. So basically , it is designed to provide services to a computer. For example: Antivirus, scanning disk and disk cleaners etc.
- 18. 3. Application Software •An application software is a set of one or more programs, designed to solve a specific problem or do a specific task. For example: Microsoft Word, Microsoft PowerPoint etc • There are two types of Application Software, they are: a) Packaged Software b) Tailored Software
- 19. a) Packaged Software PackagedSoftware is a generalized set of programs designed to meet wide variety of users for a particular type of work. For Example: MS-Word, MS- Excel,Photoshop etc.
- 20. b) Tailored Software Tailoredsoftware is a kind of software designed to meet the requirement of a specific problem of an individual or organization. For example: Result processing software, Bill producing software of a department Store.
- 21. Assessment Questions: 1) Whatis Utility Software? 2) Write 2/2 difference between Packaged and Tailored software.
