The world does not revolve around the PC.  Nor did it then.
Inexpensive video terminals, first at 1200 baud then at the
unheard of 9600 baud, and dot matrix printing terminals had
essentially replaced the ASR/KSR-33, -35, and -37 (which had
lower case letters) by the middle of the 1970s.

The KSR was keyboard send/receive.  What did ASR mean?

110 baud is correct; 11 CPS is incorrect.  Each character
was 11 bits (1 start bit, 7 data bits, a parity bit, and
2 stop bits).  110 baud / 11 bits/char = 10 char/second.

Correct.

answer to above quiz:

ASR was automatic send/receive.  A paper tape reader/punch was
attached on the left side.  If a prepunched paper tape was
loaded, an inquiry from the host computer would start it going.

Your could use the keyboard and paper tape punch to make tapes
without being connected to a computer.  Vice-versa, you could
print tapes to the printer while off-line.

That's also why DEL has character value 0x7F in ASCII.  It's
all holes punched in the paper tape.  Literally a strike-out
character when you made a mistake in punching a tape off-line.
(Lots of DEL characters was a great way to make paper tape)
