1. 1.00 Digital Literacy Unit Objective: 1.01 Computer Basics

2. What Is A Computer? An electronic device that: Receives data Processes data Stores data, and Produces a result (output). Uses hardware and software Variety of types and sizes

3. Types of Personal Computers Desktop Computer: designed to be used on a desktop. Notebook 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.

4. Tablet computer: similar to a laptop, but equipped with a touch screen and/or handwriting recognition Netbook: similar to a laptop, but smaller, lighter, and more battery life Other Types of Personal Computers

5. Hardware The tangible, physical equipment that can be seen and touched such as: Computer Case Monitor Keyboard and Mouse Disk Drive Speakers

6. Monitor Keyboard Mouse Printer Speaker Computer Case (Processor inside) Floppy Disk Drive CD-ROM/DVD Drive PARTS OF A COMPUTER SYSTEM

7. What you don’t see… CPU (Central Processing Unit) The “brains” of the computer housed on a tiny silicon chip inside the computer case. How Stuff Works VideoVideo

8. IPOS CYCLE The Information Processing Cycle consists of: I nput Devices P rocessing Devices O utput Devices S torage Devices

9. Input Devices Joystick Mouse/Trackball Light Pen Pointing Stick Touch Pad Keyboard Touch Screen Bar Code Reader Scanner Microphone Graphics Tablet Digital Camera

10. Processing Device Central Processing Unit (CPU) – known as the “ brain ” of the computer and is responsible for processing the information that has been entered into the computer

11. Output Devices Monitor: a screen that displays information such as text and numbers. Softcopy Printer: gives you information from the computer in printed form. Hardcopy Speakers: allow you to hear voice, music, and other sounds from your computer.

12. Storage Devices Hard Disk Drive: used to store data inside of the computer. Magnetic platter that holds a large amount of information Allows the fastest access RAM (Random Access Memory) - temporary, short term ROM (Read Only Memory) - long-term

13. Storage Devices 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 : a compact disk that reads only memory. CD- RW : a device that allows you to read and write to a compact disk

14. Storage Devices (Con.) DVD Digital Video Disks: Used for Movies USB/Jump Drive/Flash Drive : A completely portable disk and disk drive. What is the only Internal Storage Device? Zip Disks: A storage option with larger capacity than a Floppy or CD.

15. Which Storage Device Holds The Most Information? FLOPPY DISKS 1.44 MB CD-ROM DISC 640 MB DVD DISC 17 GB HARD DRIVES 80 and above GB USB/Flash Drive 2, 4, 8, or 16 GB ZIP DISKS 750 MB

16. Which Storage Device Holds The Most Information? Name These Devices:

17. JUST A FEW MORE THINGS ABOUT HARDWARE!!!!!!! PERIPHERAL DEVICE A device attached to your computer that ENHANCES its ability to do more TASKS. LET’S NAME SOME……….

18. Keyboard An Input “PERIPHERAL” DEVICE Most common input device Function Keys: Execute a command Activate program commands Numeric Keypad: Key math operations and numbers Alphabetic Keys: Key letters Numeric/Symbol Keys: Key numbers and symbols only

19. Keyboard: Numeric Keypad 123 456 789, / * - + Enter 0 Num Lock Be sure NUM LOCK is activated! The home row keys are 4, 5, and 6.

20. Mouse An Input “PERIPHERAL” DEVICE Used to control the Cursor Point, Click, and Drag A tool used to OPERATE the computer.

21. The Information Cycle

22. WHAT DOES IPOS STAND FOR? I nput Enters data into the computer P rocessing Changes data into usable form O utput Sends data out of the computer S torage Saves for use later

23. What Happens During The IPOS Cycle? INPUT – when information is entered into the computer; the computer receives information. PROCESSING – when the computer processes/changes the data that has bee n entered. OUTPUT – when information leaves the computer. STORAGE – when information is stored/saved to be used later.

24. How The IPOS Cycle Works INPUT PROCESSING OUTPUT STORAGE

25. Directions: Choose an everyday activity and relate it to the IPOS cycle. Put your cycle on notebook paper or you could type it. Not a requirement, but graphics would spruce it up. IPOS Cycle Homework INPUT Gather all ingredients and place on the counter. Bread Peanut Butter Knife Plate PROCESSING Use the knife to dip into the jar of peanut butter and then spread the peanut butter onto a slice of bread. Place another slice of bread on top of the first. OUTPUT You now have the finished peanut butter sandwich on the plate. STORAGE Place the sandwich in a baggy to take to school for lunch.
