Review- 5Q Who created the first user-friendly computer? Steve Jobs & Steve Wozniak What term describes a computer design made available to other manufacturers? Compatible or clone What company was responsible for allowing compatible computers to happen? IBM What computer took up the size of a city block back in the 40’s & 50’s? ENIAC What four function does every computer perform? Input data, process data, output data, store data

What is a Computer? Receives data (INPUT), processes data, stores data, produces a result (OUTPUT) Computer includes: Hardware Software Peripherals In this lesson, you will begin to broaden your vision of the word computer to include many things that process and store information, including people. In fact, the word computer, in older dictionaries, is defined as a person who makes calculations. Bottom Picture: Identify HARDWARE, SOFTWARE, INPUT, OUTPUT

Information Processing Cycle Scan an item (Receives data INPUT), processes data (INTERNALLY), outputs information (ON MONITOR/RECEIPT), stores data (HD)

Where Are Computers Used? Students should name and write on the slide where they see computers used. What makes them convenient to be used everywhere?

Desktop Computer Personal computer- PC or MAC Individual user Come in case/monitor or all-in-one Case is also known as a tower. Desktop remains stationary. Easy to open & upgrade. Typical price is around $400-$1200. All-in-ones with a touchscreen can be around $800.
