Computer Functions Mrs. Bertella Career Prep

Computer Functions Computers perform the same four basic functions: ▫Input ▫Process ▫Output ▫Storage

Input Getting data into the computer Processed data is information Devices used for input include: ▫Keyboards ▫Mice ▫Voice (Microphones or Headsets with Microphones) ▫Web Cameras and Digital Cameras ▫Joysticks/Gamepads ▫Touch screens ▫Pens/Styluses (or Styli) ▫Scanner

Process To perform an operation The Central Processing Unit (CPU) is the brain of the computer; also called microprocessor or computer chip Two of the most popular companies that manufacture processors are ▫Intel ▫AMD

Output An output device is any piece of computer hardware equipment used to communicate the results of data processing Devices include ▫Monitors ▫Printers (laser, inket, color laser) ▫Headphones/Speakers ▫Projectors

Storage Storage refers to computer components, devices, and recording media that retain digital data used for computing over a period of time Storage devices include: ▫Hard drives ▫Flash memory ▫Floppy disks ▫CDs/DVDs ▫Memory cards
