**What is a partition? **
Partitioning is the operation done to your hard drive and turns hard drive into multiple sectors. Hard drive is just like a library which has different areas to store different types of books, such as one section for science, one for history, and another for literature, etc. Thus partition is just a way to manage physical space on storage devices. A single physical disk can be partitioned into multiple drives, and you can see these divided parts in Windows.
What does partition mean.
Partitions are necessary as we can't store data to a blank drive. There are two methods to partition storage device: single partition and multiple partitions. Many devices come with a single partition such as USB drives, SD card; usually there are two or more partitions on computer, for example, we have C drive which installs operating system and applications, and we may also have "D:", "E:" or "F:" to store personal data. After a partition is created, it is formatted with a type of file system such as NTFS for local drive, FAT32 or exFAT for removable disks, HFS+ for Mac computer.

Benefits of partitioning a hard drive
Most PC comes from factory with a single partition on hard drive which means there is only one C drive in File Explorer. And you have to keep your own data, Windows system, programs in the same partition. However, that is not reasonable considering safety issue, for instance, you won't be able to access data if computer fails to boot, or even lose all files after system restore. Therefore, you need to create more than one partition for your computer and you can get following benefits:

• It is troublesome to handle everything if there is only one partition on your PC. If you have multiple partitions, you can store different types of files such as documents, backup, photos in separated drives. Besides, when system partition only stores system files and applications, it'll be extremely easy for you to backup or restore OS.
• It has been proved that hard drive works better on smaller chunks of data rather than a big partition. That means computer can get a small improvement in performance if hard drive has more than one partition.
• If you want to install multiple operating systems on same PC, you'll have to create more than one partition. You might think there is no need to do that, but there are many people want to "dual boot".
