  • 1. Computer Tech 101 You will Need: 1)Something to Write With; Colored Pencils 2)Organizational Folder 3)Computer Parts and Peripherals – Bookshelf- staple 4)Pick up your Assigned Computer – Log on to LearningPoint and Open Up this PowerPoint
  • 2. Conferencing Make sure all assignments that have been given are completed by Friday. 1) All Papers signed – Brochure, AUP, Permission Form 2) All accounts created – Google, Power My Learning, Woogi and Prezi 3) What is your Tech IQ 4) Wordle 5) Tag-Team Scavenger Hunt 6) Computer Parts and Peripherals 7) 20 things I Learned on the Web – Power My Learning
  • 3. Two Assignments Added This Week 1. Tuesday: Computer Parts and Peripherals – Access this PowerPoint on Learning Point to complete 2. Wednesday:20 Things I Learned on the Web – Must have a Power My Learning Account to complete.
  • 4. Typing Tutor • 1) Go to Learning Point • 2) Log on and select MORI CLASSROOM • 3) Select Computer Tech 101 • 4) Go to this week “Jan. 27th – Jan. 31st • 5) Scroll to the bottom of the week and select “Typing Tutor” LOG ON • Username = ID Number • Password = Last name, first letter capitalized • Remember: This site will automatically track your progress
  • 5. Computer Parts and Peripherals • Peripherals- External devices attached to CPU that communicate with the outside world There are three categories: 1) Mass storage devices 2) Input devices 3) Output devices Use the words listed on your worksheet to fill in and identify each picture.
  • 6. Background Use colo red penc ils or highlight ers to un derline key poin ts. • During the late 1960’s, the integrated circuit was developed. Hundreds of transistors, diodes and resistors could be put onto a single chip. This resulted in higher operating speeds, increased capacity, better reliability AND lower cost. This also allowed designers to build computer systems using “off the shelf” components and help standardize the design of modern computer systems.
  • 7. Inside Memory A typical computer system consists of three basic sections: 1) A Processor 2) Some Memory (RAM and ROM) 3) Peripherals (input/output devices) •In bullet format record some of the differences between Random Access Memory and Read-Only Memory
  • 8. Random Access Memory or RAM • Processor is able to read and write to this type of memory • Used for changing information or for loading programs from a disk • Does not keep or preserve its contents when powered off
  • 9. Read-Only Memory or ROM • Processor can not change this memory • Built into the computer at the factory • Retains power even when the power is turned off • Useful for tasks such as starting up a computer and powering down • Also known as “firmware”
  • 10. Central Processing Unit or CPU Jobs: •Carries out the instructions of a computer program •Performs basic math, logic and input/output operations •Accepts instructions from the memory and executes those instructions •Often referred to as the “brain” of the computer •Speed of CPU is measured in “Hertz” (GHz = gigahertz)
  • 11. Central Processing Unit • Most instructions tell the processor to take a bit of data from the memory or a peripheral device and either change that data or write it either to memory or a peripheral device…(e.g. print it)
  • 12. Processing, RAM or ROM Complete the chart: 1) Circle the correct computer section responsible for the task 2) Give evidence to prove your choice is correct.
  • 13. Homework Make sure all assignments that have been given are completed by Friday. 1) All Papers signed – Brochure, AUP, Permission Form 2) All accounts created – Google, Power My Learning, Woogi and Prezi 3) What is your Tech IQ 4) Wordle 5) Tag-Team Scavenger Hunt 6) Computer Parts and Peripherals 7) 20 things I Learned on the Web – Power My Learning
