While a computer keyboard and a typewriter keyboard look similar, the underlying technology that controls how they work is completely different. The classic typewriter is a mechanic device. Pressing a key lifts a little hammer that hits a physical piece of paper, leaving the impression of whatever letter you have chosen on the paper. A computer keyboard is an electronic device connected to a silicon chip that is loaded with coded information. At its most basic, pressing the key sends a line of code to the computer telling it to display whatever letter is chosen on a computer screen. At this point, no physical object (beyond what you see on the screen) has been created and doesn't have to be. To obtain a physical print out, you would need to connect the computer to a printer, put paper in the printer and print whatever is one the screen out, a second step.

While getting a printed document entails a second step on a computer because the keyboard only produces an image on the screen, the electronic nature of the keyboard offers a range of options not available on a typewriter. For instance, fixing an error on a typewriter is a laborious physical process that involves painstakingly painting over the mistake with white-out and then retyping the letter in question. As we know, simple back-spacing on the computer keyboard allows you to start all over. You can also save documents in a computer's memory, a feature not allowed on a classic typewriter, format them in different ways, and change fonts and spacing, just for starters.

A typewriter for English language use had the same "qwerty" arrangement of letters in three rows, based on the frequency with which those letters were used in the English language. Above the rows of letters would have been a row of numerals 1-0 with alternate punctuation marks that could be typed when the key and SHIFT were pressed at the same time. Typewriters had a TAB key to indent paragraphs, a CAPS LOCK, SHIFT keys, and a RETURN key or lever which moved the typewriter head from the right to the left margin of the paper and advanced the paper down for the next line of type. Typewriters did have a BACKSPACE key for use in making corrections. Typewriters did not have CONTROL or OPTION keys, non-electronic typewriters did not have a separate number pad, they did not have arrows to move a cursor back, forward, up or down arrows, and there were no function keys, DELETE keys, PAGE UP or PAGE DOWN keys, no HOME or END keys, no ESCAPE key.
