What is a typewriter?
Before personal computers
became popular in the 1980s, virtually
every office on the planet (and many homes) had one of these mechanical
letter-writing machines. It's called a typewriter because it lets you
write on the page with pieces of
type: slugs
of metal,
with raised letters on them, that make neat, printed marks on the
paper. The raised letters are molded in reverse so they print correctly
on the page.
