What is the difference between a computer keyboard and a typewriter?uhmm... i really the answer for my homework or assignment, please help me with...

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.
