Bitcoin is a PoW Proof of work system, the block creation process is based on software using powerful mining hardware. In PoS the block creation process is also software based but there is no need for expensive mining hardware.
Staking is the process by which the next block creator is chosen. A block creator is the one in charge to validate a batch of transactions. In return, the block creator earns the block reward. Block creators are chosen based on the specifics of the coin algorithm, for example, this could be the number of coins held (the stake) and/or the amount of time the coins have been staked.
To stake, a PoS coin, the staker needs to stake coins in a wallet and then leave that wallet connected to the internet. Staking requires the lock in a number of coins. The stake ensures that the staker has a stake in the network so he does not have an incentive to attack the network with his stake.
To mine PoW cryptocurrency (such as Bitcoin) only the mining hardware is needed. When staking a certain amount of coins will be locked, if all of them are used the staking process stops. Learn more on how to make a passive income from staking crypto currencies.
