any multimedia distribution mechanism, is considered part of the IT domain. IT provides
businesses with four sets of core services to help execute the business strategy: business
process automation, providing information, connecting with customers, and productivity
tools IT professionals perform a variety of functions that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as management and administration of entire systems.
