1Introduction to Computer Basics Ms. Scales5th Grade
2What Is A Computer?An electronic device that receives data, processes data, stores data, and produces a result (output).A collection of electronic circuits, which can be on or off (open or closed).These two states of the circuit are represented by two digits, 0 and 1, called a binary system.
3What is Data? Data: People: information entered into the computer to be processed, which consists of the following:Text, numbers, sounds, and imagesPeople:the users of the computers who enter the data and use the output.
4Data CommunicationsComputer technology enables computers to communicateYou can send text, numeric data, voice or video data from one machine to another.Popular examples:InternetElectronic messages ( )Text Messages (SMS)Multimedia Messages (MMS)Istant Messages (IM)FaxesElectronic or online banking
5HardwareHardware:the tangible, physical parts of the computer equipment that can be seen and touched such as:The Computer itselfMonitorKeyboardMouseCD/DVD DriveSpeakers
6Parts of the Computer Central Processing Unit (CPU): the microprocessor, the brains of the computer.Chip contains millions of switches and pathways that help your computer make important decisions.The main chip that allows computer to do millions of calculations per second and makes it possible for users to use their computer however they need.
7Computer Technology Hard Drive Network Drive Permanently storing files, programs, and other data on your computer’s hard drive, which is like computer’s “filing cabinet”Network DriveA Storage space on a network, such as school or work network.
8Computer Memory Memory: found on the motherboard; short term and long term.Random Access Memory (RAM)memory on the motherboard that is short term; where data, information, and program instructions are stored temporarily on a RAM chip or a set of RAM chips.Read-Only Memory (ROM)memory on the motherboard that is long term; where the specific instructions that are needed for the computer to operate are stored.
9Input, 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 informationSome types of technology can be both an input and an output device!!!
11Computer Input Devices KeyboardThe hardware device used to enter letters, numbers, and commands into the computerNumeric KeyboardThe portion of the keyboard, set up like a adding machine or calculator used to enter numbers and equations quickly into the computerMouseA tool used to move the cursor and pointer around the screen
12Computer Output Devices Monitor:screen that display information such as text, numbers, and pictures.softcopyPrinter:gives you information from the computer in printed form.Hardcopy
13Three Types of Printers Dot MatrixGives a printed image in a pattern (matrix) of tiny ink dots.Less expensive and not as clearInkjet PrinterBetter quality of printed documentMachine uses an ink cartridge and a printing element to print a finer image on the paper.LaserBest quality of printed documentsLaser beam and an ink toner cartridge are used to produce the images.More expensiveQuick
14Computer Output Devices VGA PortAllows you to display your Computer or Laptop on an external monitor or projector.
15Computer Output Devices Speakers:allow you to hear voice, music, and other sounds from your computer.Modem:allows you to use your computer to communicate with other computers.
16Types of Storage Devices Hard Disk Drive: used to store data inside of the computer.this holds a large amount of information in a form the computer can understand.Accessing data is fasterAmount of data that can be stored is much more than what can be stored on a floppy disk.Size of Hard drive is measured in gigabytes(GB) mainly or megabytes(MB) in older computers
17Types of Storage Devices Portable Storage DeviceAllows you to transport computer files from one location to anotherEx. Flash/Jump Drive, CD, DVD, Floppy Disk, External Hard Drive
18Software Software Two types: The Programs that give the computer instructions that allow you to accomplish certain tasks (this is what we use computers for!)such as:write lettersanalyze numberssort filesdraw picturesplay games, etc…Two types:ApplicationSystem software programs
19Operating System Operating System Software The software that allows your computer to start up, accept input, deliver output, connect to other computers, and generally execute the task on a computer.Ex. Vista, Windows XP, Mac Leopard
20Software Application Application Software Program or Software The individual programs that carry out specific tasks on your computer that exist on the computer’s hard drive, this is what we use computers for. Ex. Microsoft Word, Photoshop, SolitaireCategories:BusinessCommunicationsGraphics and MultimediaEducation and ReferenceEntertainment and LeisureIntegrated Programs
21Business Software Database Word Processing Spreadsheet Lets you set up an electronic filing systemsEnter text and numbersFind, search, and printer info in different waysUse Ex: Address book, Card CatalogWord Processingprogram that allows you to create, edit, and print text documentsUse Ex: Report, flyer, memoSpreadsheetNumbered Rows and Lettered ColumnsIntersection of rows and columns = cellsUse Ex: Grade book, financial info
22Software Communications Graphics Software Clip art Desktop Publishing Works with your modems or network hardware and allows your computer to communicate with other computers.Exchange computer files andGraphics SoftwareUses pictures or images to help communicate messages.Clip artgraphical images to be added to documentsDesktop Publishinguses both pictures and words to give you the ability to create documentsEx:Newsletters and brochures
23Presentations Digital Presentation Software Presentation software that allows you to combine and present text, graphics, photos, videos, and other multimedia features.Ex. PowerPoint (like this one!!!), Windows Movie MakerMultimedia: combines text, graphics, animation, video, and audio.
24Software Entertainment & Leisure Education & Reference Fun Games and simulationsTests your skillsinteractiveEducation & ReferenceAvailable on many topicsHelpEasierQuickerExamples: AR, Encyclopedia, etc.
25More types of Software Freeware Shareware Probeware Software written and then donated to the public, so anyone is free to copy it and share it.SharewareSoftware that can be tried before you purchase it.ProbewareComputer assisted data collection tools
26Email E-mail (electronic mail) E-mail Attachments communicating electronically on the computer user can compose a message at one terminal that can be regenerated at the recipient's terminalAttachmentsFiles attached to an message
27Proper Computer CareKeep food and drinks away from the computer and keyboard.Avoid dusty locations.Use a surge protector.Keep magnets Away.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.
28Computer Damage Virus Anti-Virus A computer program designed to damage computer filesAnti-VirusA application designed to search for viruses and repair files on a computer
29Proper Storage Device Care Do not remove from drives while drive in running or light is on.Avoid contact with magnets and electromagnetic fields.Keep storage device stored in a clean, cool and dry place with a protective cover.Always properly eject before taking it out of the USB driveUse a virus check program on a regular basis.Avoid hot and cold locations.Make a back-up copy of your programs and files.
30Proper CD ROM CareKeep CDs stored in a clean, cool and dry place with a protective cover.Avoid touching the back side of the CD; to avoid scratches.Avoid hot and cold locations.Make a back-up copy of your programs and files.Insert into CD ROM Drive properly; label facing up.Only write on CD’s with a CD Marking Pen on a label or the correct side of the CD.
31Proper Care of Printers Avoid cold, hot, and dusty locations.Always use the correct ink or toner replacement.Always have the proper printer cable connected to your computer.Never pull paper out of a printer in motion.Do not turn off the printer while printing.Read the instruction manual before operating a printer.Always use the proper type of paper in your printer.
