Whenever someone talks about the stock market as a place where equities are exchanged between buyers and sellers, the first thing that comes to mind is either the New York Stock Exchange (NYSE) or Nasdaq, and there's no debate over why. These two exchanges account for the trading of a major portion of equities in North America and worldwide. At the same time, however, the NYSE and Nasdaq are very different in the way they operate and in the types of equities traded therein. Knowing these differences will help you better understand the function of a stock exchange and the mechanics behind the buying and selling of stocks.
Location, Location, Location
The location of an exchange refers not so much to its street address but the "place" where its transactions take place. On the NYSE, all trades occur in a physical place, on the trading floor in New York City. So, when you see those guys waving their hands on TV or ringing a bell before opening the exchange, you are seeing the people through whom stocks are transacted on the NYSE.
The Nasdaq, on the other hand, is located not on a physical trading floor but on a telecommunications network. People are not on a floor of the exchange matching buy and sell orders on behalf of investors. Instead, trading takes place directly between investors and their buyers or sellers, who are the market makers (whose role we discuss below in the next section), through an elaborate system of companies electronically connected to one another.
Dealer vs. Auction Market
The fundamental difference between the NYSE and Nasdaq is in the way securities on the exchanges are transacted between buyers and sellers. The Nasdaq is a dealer's market, wherein market participants are not buying from and selling to one another directly but through a dealer, which, in the case of the Nasdaq, is a market maker. The NYSE is an auction market, wherein individuals are typically buying and selling between one another and there is an auction occurring; that is, the highest bidding price will be matched with the lowest asking price. (For more on different types of markets, see Markets Demystified.)
Traffic Control
Each stock market has its own traffic control police officer. Yup, that's right, just as a broken traffic light needs a person to control the flow of cars, each exchange requires people who are at the "intersection" where buyers and sellers "meet", or place their orders. The traffic controllers of both exchanges deal with specific traffic problems and, in turn, make it possible for their markets to work. On the Nasdaq, the traffic controller is known as the market maker, who, we already mentioned, transacts with buyers and sellers to keep the flow of trading going. On the NYSE, the exchange traffic controller is known as the specialist, who is in charge of matching up buyers and sellers.

The definitions of the role of the market maker and that of the specialist are technically different; a market maker creates a market for a security, whereas a specialist merely facilitates it. However, the duty of both the market maker and specialist is to ensure smooth and orderly markets for clients. If too many orders get backed up, the traffic controllers of the exchanges will work to match the bidders with the askers to ensure the completion of as many orders as possible. If there is nobody willing to buy or sell, the market makers of the Nasdaq and the specialists of the NYSE will try to see if they can find buyers and sellers and even buy and sell from their own inventories.

Perception and Cost
One thing that we can't quantify but must acknowledge is the way in which the companies on each of these exchanges are generally perceived by investors. The Nasdaq is typically known as a high-tech market, attracting many of the firms dealing with the internet or electronics. Accordingly, the stocks on this exchange are considered to be more volatileand growth oriented. On the other hand, the companies on NYSE are perceived to be more well established. Its listings include many of the blue chip firms and industrials that were around before our parents, and its stocks are considered to be more stable and established.
Whether a stock trades on the Nasdaq or the NYSE is not necessarily a critical factor for investors when they are deciding on stocks to invest in. However, because both exchanges are perceived differently, the decision to list on a particular exchange is an important one for many companies. A company's decision to list on a particular exchange is affected also by the listing costs and requirements set by each individual exchange. The entry fee a company can expect to pay on the NYSE is up to $250,000 while on the Nasdaq, it is only $50,000-$75,000. Yearly listing fees are also a big factor: on the NYSE, they based on the number of shares of a listed security, and are capped at $500,000, while the Nasdaq fees come in at around $27,500. So we can understand why the growth-type stocks (companies with less initial capital) would be found on the Nasdaq exchange.

Public vs. Private
Prior to March 8, 2006, the final major difference between these two exchanges was their type of ownership: the Nasdaq exchange was listed as a publicly-traded corporation, while the NYSE was private. This all changed in March 2006 when the NYSE went public after being a not-for-proft exchange for nearly 214 years. Most of the time, we think of the Nasdaq and NYSE as markets or exchanges, but these entities are both actual businesses providing a service to earn a profit for shareholders. The shares of these exchanges, like those of any public company, can be bought and sold by investors on an exchange. (Incidentally, both the Nasdaq and the NYSE trade on themselves.) As publicly traded companies, the Nasdaq and the NYSE must follow the standard filing requirements set out by the Securities and Exchange Commission. Now that the NYSE has become a publicly traded corporation, the differences between these two exchanges are starting to decrease, but the remaining differences should not affect how they function as marketplaces for equity traders and investors.
Conclusion
Both the NYSE and the Nasdaq markets accommodate the major portion of all equities trading in North America, but these exchanges are by no means the same. Although their differences may not affect your stock picks, your understanding of how these exchanges work will give you some insight into how trades are executed and how a market works.
