  1. Storage & Connectivity Devices Storage & Connectivity

  2. Also known as hard disks • Internal drive stores the operating system software, application software and the user’s documents • External drives come in various sizes and is connected via a USB cable and has an external power source • Prices vary depending on size • Is portable Internal / External Hard Drive Storage & Connectivity

  3. A high-performance plug-and-play storage device that contains no moving parts • SSD components include either DRAM or EEPROM memory boards, a memory bus board, a CPU, and a battery card • Because they contain their own CPUs to manage data storage, they are a lot than conventional hard disks Solid State Drive Storage & Connectivity

  4. Use as external drive for storing large amounts of data on a magnetized medium • Typically used by organisations for backing up vast amounts of data • Can be set up to do this automatically • Sturdy and durable for long term use • Slow to retrieve and search for data Magnetic Tape Storage & Connectivity

  5. Read and written to by laser • CDs holds 650-800MB of data • DVDs holds up 17GB of data. Comes in different forms: • DVD-ROM: Read only • DVD-R: Record • DVD-RW: Re-writable • Blue-ray disks holds up to 25GB of data (single layer) or 50GB (dual layer) • Used mainly for large and high quality content Optical Storage Device Storage & Connectivity

  6. Used for storing and transferring files • Connected via USB • Small, lightweight to carry around and cheap • Large storage capacity for their size • Easy to lose / damage • Now can get encrypted so more secure Memory Sticks and Cards Storage & Connectivity

  7. Storage capacity accessed through the internet or a wide area network (WAN) connection • Purchased on an as-needed basis • Users can expand capacity almost without limit Cloud Storage Storage & Connectivity

  8. Connectivity Devices Storage & Connectivity

  9. Allow user to connect to networks via Ethernet cable or Wi-Fi • Nowadays integrally fitted into the motherboard • Most modern computers will include wireless network facility in addition to the cabled connection Network Interface Card (NIC) Storage & Connectivity

  10. Enables a computer to transmit data over, for example, telephone or cable lines • Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analogue waves • A modem converts between these two forms Modem Storage & Connectivity

  11. Typically small, box-like pieces of equipment that multiple computers can connect to • Joins together multiple local area networks (LANs) with a wide area network (WAN or the Internet) Routers Storage & Connectivity

  12. Hubs connects multiple computers together in a network • Allows each device to talk to the others • Anything that comes into one port is sent to all the others (computers) • Switches are more efficient than hubs sometimes called (intelligent hubs” • Only sends data to where it should go rather than all ports Hubs and Switches Storage & Connectivity
