    Study Notes

    Monitors

    • Most monitors have control buttons to change display settings
    • Newer monitors have LCD or LED displays, while older ones use CRT displays
    • CRT monitors are larger, heavier, and take up more desk space

    Keyboards

    • Keyboards are a main way to communicate with a computer
    • Many types of keyboards exist, but most allow for similar basic tasks

    Mice

    • There are two main types of mice: optical and mechanical
    • Optical mice use electronic eyes to detect movement and are easier to clean
    • Mechanical mice use rolling balls to detect movement and require regular cleaning

    Buttons and Ports on a Computer

    • Each computer is different, but certain buttons, ports, and sockets are common
    • Learning about these ports helps with connecting devices like printers, keyboards, and mice

    Inside a Computer

    • The motherboard is the computer's main circuit board
    • The CPU (Central Processing Unit) is located on the motherboard and carries out commands
    • CPU speed is measured in megahertz (MHz) or gigahertz (GHz)

    CPU/Processor

    • The CPU is the "brain" of the computer and performs tasks like arithmetic and logical operations
    • CPU speeds are often measured in gigahertz (GHz) or megahertz (MHz)

    RAM (Random Access Memory)

    • RAM is short-term memory that temporarily stores data for calculations
    • RAM disappears when the computer is turned off
    • RAM is measured in megabytes (MB) or gigabytes (GB)

    Memory: RAM vs ROM

    • RAM is memory available for the operating system, programs, and processes
    • ROM is pre-written memory that holds instructions for booting up the computer

    Hard Drive

    • The hard drive is long-term storage for software, documents, and files
    • Data is still saved even if the computer is turned off or unplugged

    Storage Disk: HDD vs SSD

    • SSD (Solid State Drive) is flash storage with no moving parts and is faster than HDD
    • HDD (Hard Disk Drive) is made up of magnetic tape and has mechanical parts, making it slower than SSD

    Power Supply Unit

    • The power supply unit converts power from the wall outlet to the type needed by the computer
    • It sends power through cables to the motherboard and other components

    Hardware vs Software

    • Hardware is any part of the computer with a physical structure, including internal parts
    • Software is any set of instructions that tells the hardware what to do and how to do it
