1. DIGITAL TECHNOLOGY

2. 20 Questions  Pair off with another student within your table.  Both of you are to think of your favorite in a specific category  Students will ask up to 20 yes/no questions until they are able to identify the other students favorite  Categories Animal Food Place to go

3. Communication  In order to be able to communicate most technology utilizes binary code.  Binary code is a system in which consists of two choices on/off, 1 and 0  Our alphabet utilizes 26 letters but most electronics only use the binary code.  Video: BrainPop

4. MEMORY PROCESSOR CONTROL UNIT ARITHMETIC LOGIC UNIT (ALU) INPUT DEVICES STORAGE DEVICES OUTPUT DEVICES Instructions Data Information Data Information Instructions Data Information

5. INPUT Input DevicesInput Devices:  Keyboard  Mouse  Trackball  Touchpad  Pointing stick  Touch Screen Any data or instructions entered into the memory of a computer.

6. PROCESSOR / CPU  Interprets and carries out the basic instructions that operate a computer.  Control Unit: Component of the processor that directs and coordinates most of the operations in the computer. Like a Traffic cop : It interprets each instruction issued by a program and then initiates the appropriate action to carry out the instruction

7. STORAGE  Storage Medium: Is the physical material in which a computer keeps data. Storage Medium  Floppy Disks  Zip Disks  CD’s  DVD’s  Memory Sticks  USB Flash Drives Holds data, instructions, and information for future use.

8. OUTPUT Output DevicesOutput Devices: Are hardware components that convey information to one or more people.  Monitors  Printers  Speakers  Fax Machines / Modems  Projectors  Video Card Is data that has been processed into a useful form.

9. MEMORY  RAM – Random Access Memory  Computer gets turned on programs get loaded into RAM from storage devices for use.  ROM – Read Only Memory  Refers to memory chips storing permanent data and instructions  CMOS – Complementary metal-oxide semiconductor  Retains information even when the computer is turned off, i.e. start-up Components which store instructions waiting to be executed by the processor

10. MACHINE CYCLE MEMORY PROCESSOR Student enters math problem into the memory of the computer STEP 1: The control unit fetches the math problem's instructions and data from memory. (100 x 52) STEP 2: The control unit decodes the math problem’s instructions and sends the instructions and data to the ALU. (100 x 52) STEP 3: The ALU performs \ executes calculations on the data. (100 x 52 = 5200) STEP 4: The results of the math problem are stored in memory. (5200) CONTROL UNIT ALU ARITHMETIC LOGIC UNIT 5200

11. The Internet  What is the Internet?  The internet is the largest computer network in the world, connecting millions of computers. A network is a group of two or more computer systems linked together.

12. Difference  When most people think of the internet, the first thing they think about is the World Wide Web. Nowadays, the terms "internet" and "World Wide Web" are often used interchangeably—but they're actually not the same thing.  The internet is the physical network of computers all over the world.  The World Wide Web is a virtual network of web sites connected by hyperlinks (or "links"). Web sites are stored on servers on the internet, so the World Wide Web is a part of the internet.
