IT support services refer to the various activities and tasks that are carried out in order to maintain and support information technology (IT) infrastructure in companies. This can include activities such as systems administration, network monitoring and management, help desk operations, software installation and updates, as well as security management. IT support services can be provided in-house or outsourced to a third-party provider. Many businesses choose to outsource their IT support needs in order to take advantage of the expertise and experience of a specialist provider. Outsourcing also enables businesses to focus on their core business activities rather than dealing with routine IT problems and issues.
