Typewriters, invented in the nineteenth century, are mechanical devices. I will be discussing typewriters in their classic form. As stated above, they print a letter with ink physically on a piece a paper when a user hits a key. When a user is done typing, he has a physical document. A computer, in contrast, is an electronic device. Underneath each key is a switch that engages a contact that sends a signal to the computer to store the letter typed in memory. One does not get a physical copy of the document created. Instead, what is typed is stored on a computer chip. It can be retrieved and printed, but getting a physical copy is a secondary step.

Because a computer keyboard stores the information you have typed into a chip, you can always access it, whereas you could lose your sheet of paper. (Of course, if you take good care of the paper, you will not lose it, and you can photocopy it.) The great advantage of a computer keyboard is the ability to make corrections very easily while typing. On a typewritten sheet, this is much more difficult: it involves a liquid called white-out, backspacing, and actual physical maneuvering.

While a computer keyboard and a typewriter keyboard look very similar, they work in very different ways.  A computer keyboard generally allows a user to type letters into a computer and these letters are then displayed on the screen.  Of course, the computer can usually print these letters onto a paper, but the keyboard itself does not print the letters in actual ink.  Keys on the computer keyboard rely on electronic circuits which are translated by the computer into letters.  A typewriter keyboard is far more direct.  This type of keyboard does not complete a circuit but rather moves mechanical parts (of course, some newer typewriters do use an electronic circuit, but that circuit still moves a mechanical part rather than sending a signal to a computer).  A typewriter keyboard generally allows the user to print ink letters directly onto a piece of paper.  The keys usually activate a hammer or turn a circular device covered in letters.  Then, the key causes the mechanism to be pressed against an ink strip which presses the corresponding letter onto a page.  Both keyboards fulfill the same function, to allow the user to type out letters.
