4. ImportanceWhy is it important to learn how to use a computer?Importance
5. What is a Computer?An electronic device that:accepts data (input),manipulates the data (process),provides output (output) andstores the results (storage).What is a Computer?
6. Input DevicesThe user must provide the data through an input device such as:Input Devices
7. Processing DataOnce the user provides the computer with data, he/she must tell the computer what to do with the data. The central processing unitperforms the tasks theuser tells it to do.Processing Data
8. Many people use the terms memory and storage interchangeably. However, they are not the same thing.Data in MemoryData in Memory
9. Data in MemoryMemory is a temporary holding space for data while it is being used by the user. Data in Memory
10. Data in MemoryExample: This presentation has been saved to “storage,” but we are viewing it through the computer’s memory. If I make a change to it and do not save it to “storage” again, the changes will be lost.Data in Memory
11. The computer user can store data so that he or she may access it again.Storing DataStoring Data
12. Storing DataPrimary storage consists of the hard drive which is located inside of the desktop or laptop computer.AdvantagesDisadvantagesStoring Data
13. Storing DataSecondary storage consists of any storage medium located outside of the desktop or laptop computer.AdvantagesDisadvantagesStoring Data

18. Computer ProgramsA computer program is a collection of step-by-step instructions that tell the computer how to perform a particular task or group of related tasks.Computer Programs
19. SoftwareThere are two general types of software.System softwareApplication softwareSoftware
20. System SoftwareSystem software generally comes preinstalled on your computer and you will, quite often, not even realize that you are interacting with it.Operating SystemsDevice DriversSystem Software
21. Operating SystemsThe two operating systems most users encounter are Microsoft Windows and Mac OS X. Operating systems contain the instructions that allow the parts of a computer to work together by performing most, if not all, of the “behind the scenes” tasks such as transferring data from memory to storage devices.Operating Systems
22. Device DriversDevice drivers contain the instructions which tell the computer how to interact with that particular device.Many device drivers come preinstalled on the operating system but devices such as printers and scanners come with a device driver to install on the computer if necessary.Device Drivers
23. Application SoftwareSoftware the computer uses to carry out a specific task as specified by the user.Application Software
24. Word ProcessingSoftware that enables the user to enter, edit, format and print documents containing primarily, but not limited to, text.Word Processing
25. SpreadsheetsSoftware that enables the user to enter, edit, format, print, sort and calculate primarily numeric data.Spreadsheets
26. Web BrowsersSoftware that enables the user to access, retrieve and view documents and other resources on the Internet.ChromeWeb Browsers
27. EmailSoftware that enables the user to send and receive electronic mail, commonly known as email over the internet.Email
