Address
From CryptoWiki
All cryptocurrencies require addresses, or public identifiers, to send and receive funds. A wallet is an interface for users to access their address and it's funds.
A bitcoin address looks like 1DSrfJdB2AnWaFNgSbv3MZC2m74996JafV. It consists of a string of letters and numbers starting with a "1" (number one). Just like you ask others to send an email to your email address, you would ask others to send you bitcoin to your bitcoin address.
