The use of the word back would normally be used to discuss a direction or a part of the body. But the word back is quite versatile; in other words, there are a lot of ways to use it. Let’s take a look at some examples:

• In the sentence “I have not heard back from them.”, back means return or reply to something I sent them.
• In the sentence “This problem is going to come back to haunt us.” back also means return in the sense that it happened once before. This is different than if you say “This problem is going to come to haunt us.” which refers only to the future problem not the current situation.

front end refers to the visual parts of an application. This is also known as the graphical user interface or GUI which is pronounced GOOEY. back end refers to the operations that occur behind the front end such as saving data, or doing calculations or connecting to other computers to retrieve information. Examples of the back end include databases, applications such as running Power Point or a word processor on the server.

So what is a server? This is basically any computer that allows other computers to connect to it. Often you will hear the word server used in the following:

• print server - which only handles printing of documents.
• application server - which only runs applications like a word processor or some other program that could be custom developed.
• database server - which runs a database like mySQL or Oracle or SQL Server or PostGreSQL.

Now what about the financial world? Don’t we use these words too? Yes. Mutual funds use these words to describe payments made to the fund when a customer purchases shares of the fund. These are specifically called front end and back end loads. A front end load is like commissions paid to a stock broker to purchase shares of stock on the stock market. A back end load is the fee paid to sell your shares of the mutual fund.
