Which of the following recently developed technologies has not greatly increased the speed of information dissemination?
a.
smartphones
b.
e-mail
c.
typewriter
d.
teleconferencing

The option which has not greatly increased the speed of information dissemination is C. a typewriter. Smartphones, emails, and teleconferencing all need the Internet in order to function, and as you already know, the Internet is the fastest way to disseminate information and spread it all over the world. A typewriter obviously has no Internet access and is not really practical when compared to these other options.
