You then need only replace the modem card which is held in place by a single screw. I have often expressed a preference for external modems, but the fact that the proper chip is part of the new modem card is a big plus where older computers are involved. My main objection is that when a communication problem occurs, you cannot see the modem status lights. Also there is no way to shut off the modem, other than powering down the entire computer. Bookmarks You often refer to bookmarks when writing about the Internet.
Bookmarks are a way to enter complex addresses into a list.
To do this, you assign a short name to that site and let the computer associate it with its address. As an example, note the Internet address at the bottom of this article where these columns can be found. By the way, this code is called a URL, Universal Resources Locator. Many Internet addresses are far more complex and might be more than one line long. By using a short description, there is no need to remember the long address or risk typing errors when entering it into the computer.
