Before we begin the discussion on how IT behaves in small businesses, let's look at the definition of IT. Computing, short for "information technology", is a term that includes all forms of technology used to create, store, exchange and use information in its various forms such as business data, voice conversations, still images, movies, multimedia presentations, and other forms, including those not yet designed. It is a convenient term to include both telephony and computer technology in the same word (Applegate). Technology has become the most powerful tool in recent times, driving the “information revolution”. The Internet, which is an important part of information technology, can be dated to July 1961, when Leonard Kleinrock of MIT published the first paper on the theory of packet switching and the first book on the subject in 1964. In 1966, Roberts joined DARPA to develop the computer network concept and quickly developed his plan for "ARPANET", which he published in 1967. Next, APRANET expanded into the Internet (Opfer). Today, the Internet is mainly used in communication, research, education and financial transactions. Information technology has emerged in several fields, such as science, architecture, security, etc. Information technology can help solve complex problems: computing for business, medicine, science and other fields. Information technology also provides more jobs for people. Computer support specialists are a job that involves providing help and advice to people and organizations using computer software or equipment. Database administrators use specialized software to store and organize data, such as financial information and customer shipping records. Software developers are the creative minds behind computer products...... middle of paper ......history of the Internet itself: a summary of online Internet histories available at the turn of the century.
