Evaluate the roles of hardware devices 2 . Printer Web Cam Memory Stick L/A: To identify common hardware components in a computer system and how they function Motherboard • Circuit board • Connects internal components • Slots for RAM, ROM, CPU, GPU My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . CPU L/A: To identify common hardware components in a computer system and how they function • Central processing unit • Interprets and executes commands from • software • hardware • The “brains” of the computer? • This My is Learning the case, not the Objectives 1 Identify different internal and external hardware devices CPU! . Evaluate the roles of hardware devices 2 . L/A: To identify common hardware components in a computer system and how they function Random Access Memory (RAM) • Where data is temporarily stored • Stores running applications, files and operating system • Volatile • Erased when the power is off My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . L/A: To identify common hardware components in a computer system and how they function Read-only memory (ROM) • Stores permanent information • Non-volatile • Stores the BIOS, the start-up instructions for the computer • Not erased when the power is off My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . L/A: To identify common hardware components in a computer system and how they function Video card / GPU • Outputs graphical information… • To a monitor, projector etc • Has: • A processor • Memory (RAM) • Cooling • Output ports My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . L/A: To identify common hardware components in a computer system and how they function Sound card • Outputs sound through… • Speakers • Headphones • Inputs recorded sound through a… • Microphone My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . L/A: To identify common hardware components in a computer system and how they function HDD / SSD • Main internal storage • Permanent storage • Stores data, files, application and systems software My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . L/A: To identify common hardware components in a computer system and how they function RAM, ROM and BIOS RAM Random access memory Internal chip Where data is stored when running applications Erased when the computer is turned off Volatile Can be read and written to ROM Read only memory Internal chip Stores start up information (e.g. BIOS) Permanent storage, will not be erased Non-volatile Read only My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . BIOS L/A: To identify common hardware components in a computer system and how they function • Basic input/output system • Stored on ROM • When the computer is turned on it… • Checks hardware and starts the operating system My Learning Objectives 1 Identify different internal and external hardware devices . Evaluate the roles of hardware devices 2 . Plenary – What am I? I am the physical components of a computer system HARDWARE I am the main internal computer storage INTERNAL HDD/SSD CPU I am the programs or instructions that control the computer system SOFTWARE I am an internal chip where data is temporarily stored RAM I am used to store the configuration data of the computer ROM system I am the ‘brains’ of the computer system
