1. Introduction

Introduction:
A Bank is a financial institution and a financial intermediaries that accepts deposit and channels those deposits into lending activities, either directly by loaning or indirectly through capital markets. A bank is the connection between customers that have capital deficits and customers with capital surpluses.
Due to their influence within a financial system and an economy, banks are generally highly regulated in most countries. Most banks operate under a system known as fractional reserve banking where they hold only a small reserve of the funds deposited and lend out the rest for profit. They are generally subject to minimum capital requirements which are based on an international set of capital standards, known as the Basel Accord.

Banking
Banking in the modern sense of the word can be traced to medieval and early Renaissance Italy, to the rich cities in the north like Florence Lucca, Siena, Venice and Genoa. The Bardi and Peruzzi families dominated banking in 14th century Florence, establishing branches in many other parts of Europe. One of the most famous Italian banks was the Medici Bank, set up by Giovanni di Bicci de' Medici in 1397. The earliest known state deposit bank, Banco di San Giorgio (Bank of St. George), was founded in 1407 at Genoa, Italy.

Origin of the word “bank”
The word bank was borrowed in Middle English from Middle French banque, from Old Italian banca, from Old High German banc, bank "bench, counter". Benches were used as desks or exchange counters during the Renaissance by Florentine bankers, who used to make their transactions atop desks covered by green tablecloths.[12]
One of the oldest items found showing money-changing activity is a silver Greek drachm coin from ancient Hellenic colony Trapezus on the Black Sea, modernTrabzon, c. 350–325 BC, presented in the British Museum in London.
