Inputs are devices that are used to input information into the computer. They allow the user to communicate and perform actions. The most common inputs are keyboards and mice, but other inputs such as webcams are also available.

USB - Often referred to as a "thumb drive" or "jump drive," a USB drive is a removable storage device that plugs into a computer's USB port.
Memory - Computer hard disk drives are slow, so computers use RAM or Random Access Memory to temporarily store programs so that they can be accessed faster, thereby allowing you to run programs without having to wait a long time. The more memory or RAM that a computer has, the more programs it can store and run at the same time without slowing the computer down.
Disk Space -
Disk space is the amount of space on your hard drive that you have available to store files and programs. Disk space is typically measured in megabytes, gigabytes, and terabytes.
Units (MB, GB, TB)
MB or Megabyte stands for roughly one million bytes.
GB or Gigabyte stands for roughly one billion bytes.
TB or Terabyte stands for apporiximately one trillion bytes. Hard drives today have a disk space of multiple Terabytes.
