Understanding Your Own Computer 3 KEY CONCEPTS ◦Purpose of A Computer  Turn data into information  Data: the raw facts and figures  Information: data that has been summarized and manipulated for use in decision making ◦Hardware vs. Software  Hardware is the machinery and equipment in the computer  Software is the electronic instructions that tell the computer how to perform a task

Understanding Your Own Computer ◦The Basic Operations  Input: What goes in to the computer system  Processing: The manipulation a computer does to transform data into information  Storage: ◦ Temporary storage: Memory is primary storage ◦ Permanent storage: Disks and media such as DVDs and CDs are secondary storage  Output: What comes out ◦ Numbers or pictures on the screen, printouts, sounds  Communications: Sending and receiving data

TWO PARTS OF ICT Computer technology -Computer: a programmable, multiuse machine that accepts raw data and processes it into information we can use -Purpose: speed up problem solving and increase productivity Communications technology -Consists of electromagnetic devices and systems for communicating over long distances
