   • Advantages (Hard Disc Drive, HDD)
     • Relatively cheap per unit of storage.
     • Fast access and retrieval times compared to other storage devices.
   • Disadvantages (Hard Disc Drive, HDD)
     • Can be easily damaged, will slow down and eventually break over time.
     • Slower access than Solid State Drives.

5. What is a wireless connection?

   • Allows devices to stay connected to the network but roam without any wires.
   • Advantages
     • Improved data communications, easier and cheaper to install, flexibility, new opportunities.
   • Disadvantages
     • Transmission speeds (slow), installation problems, security.
   • Wireless networking, often known as Wi-Fi is a way of getting broadband internet without wires.

6. Buffer in computer

   • A buffer may be used when moving data between processes within a computer.
   • A data buffer is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another.
