For example, there may be three buyers who have placed orders for buying Microsoft shares at $100, $105 and $110, and there may be four sellers who are willing to sell Microsoft shares at $110, $112, $115 and $120. The exchange (through their computer operated automated trading systems) needs to ensure that the best buy and best sell are matched, which in this case is at $110 for the given quantity of trade.
The stock market refers to the collection of markets and exchanges where regular activities of buying, selling, and issuance of shares of publicly-held companies take place. Such financial activities are conducted through institutionalized formal exchanges or over-the-counter (OTC) marketplaces which operate under a defined set of regulations. There can be multiple stock trading venues in a country or a region which allow transactions in stocks and other forms of securities.
The stock exchanges also maintain all company news, announcements, and financial reporting, which can be usually accessed on their official websites. A stock exchange also supports various other corporate-level, transaction-related activities. For instance, profitable companies may reward investors by paying dividends which usually comes from a part of the company’s earnings. The exchange maintains all such information and may support its processing to a certain extent. (For related reading, see "How Does the Stock Market Work?")
Warning 2: this is serious. If you don’t believe me, just go on Reddit (r/Cryptocurrency) and look for posts of people who ask for help. There are some devastating stories out there which are all based on greed, credulity, inexperience and/or outright stupidity. You may become rich, but you may also lose everything. People are taking loans with high repayment rates to buy at peak price and will end up ruined. Young inexperienced people have burned their relatives’ lifetime savings, others have no money to pay their university tuition. Don’t be those guys.

While both terms - stock market and stock exchange - are used interchangeably, the latter term is generally a subset of the former. If one says that she trades in the stock market, it means that she buys and sells shares/equities on one (or more) of the stock exchange(s) that are part of the overall stock market. The leading stock exchanges in the U.S. include the New York Stock Exchange (NYSE), Nasdaq, and the Chicago Board Options Exchange (CBOE). These leading national exchanges, along with several other exchanges operating in the country, form the stock market of the U.S.

The two main types of IRAs are Roth and Traditional, and the difference between them has to do with when you pay taxes. With a Roth IRA, you contribute money after taxes, so your withdrawals are tax-free in retirement. In most cases, contributions to a Traditional IRA are tax deductible, but you'll pay taxes when you withdraw money in retirement.

When you buy some cryptocurrency, the money will be withdrawn from your bank account or card and you will be credited in your exchange in a sum matching the cryptocurrency you have purchased. Each exchange may allow you to trade for one or more cryptocurrencies. Each cryptocurrency on the exchange will have its own wallet. You can store your cryptocurrency on an exchange but it’s not a recommended practice. I will cover this in a section called Wallets.

The stock market is made up of exchanges, like the New York Stock Exchange and the Nasdaq. Stocks are listed on a specific exchange, which brings buyers and sellers together and acts as a market for the shares of those stocks. The exchange tracks the supply and demand — and directly related, the price — of each stock. (Need to back up a bit? Read our explainer about stocks.)
