["account", "accounts", "wallet", "wallets"]
The Basics
Those familiar with Monero's predecessors will be more familiar with the term *wallet* to describe this. In Monero we call this an account, and it is a private account owned and operated by a Monero user.
Your account contains all of the Monero @transactions you have sent and received. Your account balance is a sum of all the Monero you've received, less the Monero you've sent. When using Monero you may notice that your account has two balances, a locked and an unlocked balance. The unlocked balance contains funds that can be spent immediately, and the locked balance contains funds that you can't spend right now. You may receive a transaction that has an @unlock-time set, or you may have sent some Monero and are waiting for the @change to come back to your wallet, both situations that could lead to those funds being locked for a time.
A key difference between traditional electronic currency and Monero is that your account resides only under your control, normally on your computer, and cannot be accessed by anyone else if you [practice good security](#practicing-good-security).
Multiple Accounts
There are no costs attached to creating a Monero account, and there are no fees charged except for individual @transaction fees that go to @miners.
This means that individuals can easily create a Monero account for themselves as well as a joint account to share with their partner, and individual accounts for their children. Similarly, a business could create separate accounts for each division or group. Since Monero's @transaction fees are quite low, moving funds between accounts is not an expensive exercise.
Cryptographic Keys
Monero relies heavily on a cryptography principle known as *public/private key cryptography* or *asymmetric cryptography*, which is thoroughly detailed in [this Wikipedia article](https://en.wikipedia.org/wiki/Public-key_cryptography).
