1 1.00 Describe the purpose, components, and use of a computer system. Unit Objectives:
2 What Is A Computer?An electronic device that receives data, processes data, stores data, and produces a result (output).
3 The Parts of A Computer Computer Case CPU (Central Processing Unit) The “brains” of the computer house on a tiny silicon chip inside the computer case.Disk DriveCD ROM DriveMonitorKeyboardMouseSpeakersPrinterScanner
4 Types of Personal Computers Desktop computer: designed to be used on a desktop.Notebook/Tablet computer: designed to be used on a desktop but still small enough to be portable.Laptop computer: designed to be small enough and light enough to be used on your lap.
5 Proper Computer CareKeep food and drinks away from the computer and keyboard.Avoid dusty locations.Use a surge protector.Keep away from magnets.Do not block vents on the CPU.Avoid bright sunny locations.Do not move the computer while it is in use.Always exit programs properly.Use a virus check program on a regular basis.
6 Proper Diskette CareDo not remove from drives while drive is running or light is on.Avoid contact with magnets and electromagnetic fields.Keep disks stored in a clean, cool and dry place with a protective cover.Keep protective metal slider in place.Use a virus check program on a regular basis.Avoid hot and cold locations.Make a back-up copy of your programs and files.
7 HardwareThe tangible, physical equipment that can be seen and touched such as:Computer CaseMonitorKeyboard and MouseDisk DriveSpeakers
8 SoftwareThe intangible set of instructions that tells the computer what to do; known as programs or software programs.
9 Types of Software Operating System Software Application Software Sets the rules for how computer hardware and application software work together, controls the operation of the computer.Example: WindowsApplication SoftwareLets you accomplish specific tasks based on your needs.Examples: MS Word, Excel, Access, MS Works
10 Operating System Software Tasks Boots (starts up) the computerFormats disksCreates foldersSaves and retrieves filesMoves and copies filesEvery Computer Has Operating System Software!
11 Types of Application Software Word ProcessingProgram that allows you to create, edit, and print text documentsReport, flyer, memoSpreadsheetNumbered Rows and Lettered ColumnsIntersection of a row and column is a cellGrade book, financial infoDatabaseLets you set up an electronic filing systemEnter text and numbersFind, search, and print info in different waysAddress book, Card Catalog
12 Input, Output, & Storage Devices Input device: hardware that allows you to communicate with your computer.Output device: hardware that allows your computer to communicate with the userStorage device: allows you to store or retrieve information
14 Computer Output Devices Monitor: screen that displays information such as text, numbers, and pictures.SoftcopyPrinter: gives you information from the computer in printed form.HardcopySpeakers: allow you to hear voice, music, and other sounds from your computer.
15 Computer Storage Devices Hard Disk Drive: used to store data inside of the computer.Magnetic platter that holds a large amount of information in a form the computer can understand.Floppy Disk: flat circles of iron oxide-coated plastic enclosed in a hard plastic case.Most are 3 ½ inches and have a capacity to hold 1.44 MB or more of data.CD ROM Drive: a compact disk that reads only memory.CD-RW: a device that allows you to read and write to a compact disk
