TermsTalking about our eld , when we are referring to the term computer connectivity we have a complex of computer hardware , software and physical appliance, and we mean the way and how computers can communicate and allot common sources with the use of an intelligent or common network .With the term Data Communication we mean the exchange of information under the form of data between Data Terminal Equipment .
