22. Computers and technology has advanced so much in the past 20 years. Not only has
computers improved our Business skills as well as our personal communication skills.
Technology has grown and continues to grow, we have incorporated computer technology in to
our daily lives. From the moment we receive a text message on our smart phone to signing in
to our social networking sites. We strive to have the latest and greatest technology, every year
we are progressing with newer more innovated technology.
Computerization has improved our way of creating and storing information . Technology
is becoming more faster more efficient and in a more confined size. We can access the Internet
not only from our home computers by also from our smart phone on the go. Hands free devices
is also becoming more popular with many devices as well as Voice command and then The
business industry as adapted to the use of computer technology so much that for some jobs it is
a requirement to be able to use this technology. Many educational institutes are investing into
educational courses that teach students how to operate computer programs and software.
From basic processors such as Microsoft office, to advanced design programs such as
AutoCAD.
