Debit and Credit

Debit and Credit are the two alphabets of accounting (like in English ABC..). Debit and Credit represent the two aspects of a transaction and this is known as double entry system

As we know every financial transaction has two effects something always "gives" and something always "receives" we have to record the both aspects of a transaction. Double entry (Debit and Credit) simply implies that each transaction should be recorded twice in the books of accounts. 

For example a business has purchased equipments for $2500, in this case equipments (Debit) should be recorded in equipment account and cash (Credit) in cash account. Therefore, there are double aspects of that transaction
