As mentioned, there is also a public key. This causes some confusion, as some people assume that a bitcoin wallet address and the public key are the same. That is not the case, but they are mathematically related. A bitcoin wallet address is a hashed version of your public key.

Every public key is 256 bits long — sorry, this is mathematical stuff — and the final hash (your wallet address) is 160 bits long. The public key is used to ensure you are the owner of an address that can receive funds. The public key is also mathematically derived from your private key, but using reverse mathematics to derive the private key would take the world’s most powerful supercomputer many trillion years to crack.

It’s saved on a Windows machine, for example, in the C:UserYournameDocumentsAppDataRoamingBitcoinfolder. Make sure to create one or multiple backups of this wallet.dat file on other storage devices, such as a USB stick or memory card. The bitcoin wallet software will let you import a wallet.dat file in case your previous file is damaged or lost, restoring your previous settings, including any funds associated with your bitcoin wallet address.
