IT support for business is the term for a comprehensive package of services that covers all needs and requirements a modern business may have in relation to information technology. These services may include IT infrastructure support and maintenance, data safety and computer security services, email server administration, proprietary software development and application maintenance, electronic data exchange and documentation processing support, webmastering, computer training services for the staff, and other types of IT assistance. In fact, it would be difficult to imagine a modern business not using any kind of IT support in its operation.
15-20 years ago even small businesses used to have on the team an IT computer support specialist who was typically a jack of all trades. Nowadays, fewer and fewer corporations still have an IT department, whereas most companies opt to get more versatile and all-inclusive 24/7 IT support from specialized business IT support providers. This makes perfect sense: a dedicated computer firm working on an IT support contract simply has more resources and knowledge than an in-house team, and often costs less.
