What is a 4 TB External Hard Drive?

External Hard Drives are hard drives designed to be plugged or installed outside of the computer case. They simply sit beside the computer and plugged to the computer using a short length of interface cable. They are generally installed by using a USB (Universal Serial Bus) or a firewire interface cable.

Just for comparison, there are hard drives that are called Internal Hard Drives, because they need to be installed inside the computer case, necessitating the opening of the computer case in order for them to be installed.

External hard drives can either be a Desktop or a Portable drive. Portable types are designed to be smaller than the Desktop ones, and they are meant to be carried around from one place to another.

Hard drive disk space capacities, which is a measure of how much information a certain hard drive can store, is expressed in MB (Mega Byte), GB (Giga Byte), and TB (Tera Bytes). A Megabyte is equal to 1 milllion bytes, while a Gigabyte is equal to 1 billion bytes, and a Terabyte is 1 trillion bytes. Also, 1000MB is equal to 1GB and 1000GB is 1TB.
