With the increasing use of technology in modern times, there is a growing requirement to provide technical support. Many organizations locate their technical support departments or call centers in countries with lower costs. There has also been a growth in companies specializing in providing technical support to other organizations.

Technical support centers can be certified to help ensure a particular business is maintaining a high level of information technology service and support standards.

Technical support may be delivered by different technologies depending on the situation. For example, direct questions can be addressed using SMS, email or fax; basic software problems can be addressed over the telephone or using remote support; while more complicated problems with equipment may need to be dealt with in person.
