TRANSCRIPT

  • Computers -The Journey Insidecontinues

  • Bit by bit 8 bits =

    1 byte about 1,000 (one thousand) bytesabout 1,000,000 (one million) bytesabout 1,000,000,000 (one billion) bytes kilobyte = gigabyte = megabyte =

    1 KB =

    1 MB =1 GB =

    And, each byte holds 8 bits capable of forming 256 combinations of 1/0 - WOW!

  • Bit by bit What does the number that comes before one of these abbreviations KB, MB, & GB represent?Yes, the computer's memory capacity.

    For example, What does it mean if a computer has 64MB of RAM?The computer can handle 64,000,000 (64 million) bytes of random access memory (that's 64,000,000 microscopic 8-bit panels). Hard disk space is also measured in bytes. So, explain what a 15GB hard drive means?Hard drive has 15,000,000,000 (15 billion) bytes for storing memory.

  • Computers use a variety of devices to store informationSTORAGE MEDIA:Hard Drives (80 GB)DVD (17 GB)Thumb drives (16 MB - 4 GB)CD ROM (640 MB)Floppy Disks (1.44 MB)

  • Floppy Disk

  • CD-ROM

  • DVD

    Digital Video Disk

  • Hard Drive

  • Storage device, also known as:Pen DriveThumb DriveUSB Key

    1 to 4 gigabytes of information

    What is a USB Flash Drive?
