2. Lesson 5 Information and the computer Computer Software Presented by Andrey Koptelov Fonville Middle School Technology Applications Class

3. CPU inside case Input and Output InputCPUOutput The CPU The CPU processes information Enter information with mouse or keyboard Output The result is shown as You can show input and output with a flowchart

4. How Does the Hardware Know What to Do With Input? SOFTWARE.When you put information, a computer runs a program, or SOFTWARE. SoftwareSoftware is a set of instructions that tells a computer what to do. When software is running, it tells the CPU how to process the information.

5. Hardware and Software Hardware can be seen or touched. Software at work is invisible. The “instructions” the computer receives are electronic. Hardware will not work without software. Software cannot do it job without hardware.

6. There are Four Main Types of Software Operating systems or system software. 1. Operating systems or system software. Windows XP, Windows 98, Macintosh OS Applications software. 2. Applications software. MS Paint, Internet Explorer, Ultra Key, Games Utilities software. 3. Utilities software. Norton Utilities, McAfee Antivirus, Zip Magic Programming languages. 4. Programming languages. C++, Java, Visual Basic, HTML

7. Give some samples. What operating systems do you know? What application do you know? What kind of utilities do you know? What programming languages do you know?

8. Operating systems operating system isa program thatBetween the hardware and the application software lies the operating system. The operating system is a program that conducts the communication between the various pieces of hardware like the video card, sound card, printer, the motherboard and the applications.

9. Applications Software Applications software lets you do a particular job with your input. Some job include drawing a pictures, writing a report and finding information. Examples: Examples: MS Paint, Ultra Key, MS Word, Internet Explorer etc.

10. Utilities Software Utilities software helps you keep a hard drive in order and a computer running smoothly. For example it can help you find a virus.

11. Programming Languages computer program is a set of detailed directions telling the computer exactly what to do, one step at a time. Programming language is a special language which can be used for describing these detailed directions telling the computer what to do.

12. Lesson Review Write down your answers for the following questions operation system 1.What does operation system do? applications software 2.What does applications software do? utilities software 3.What does utilities software do? programming languages 4.What is a reason you would use a programming languages for? CRITICAL THINKING How is input different from output?
