Computer MCQs for All Competitive Exams

Definition: The term Internet today refers to the global network of public computers running Internet Protocol. The Internet supports the public WWW and many special-purpose client/server software systems. Internet technology also supports many private corporate intranets and private home LANs. The term “Internet” was originally coined in the 1970s. At that time, only the very meager beginnings of a public global network were in place. Throughout the 1970s, 1980s, and 1990s, a number of smaller national networks like ARPANET, BITNET, CSNET, and NSFNET evolved, merged, or dissolved, then finally joined with non-US networks to form the global Internet.
