What is a Computer Operating System

In computing, an operating system (OS) is an interface between hardware and the user.  The operating system is responsible for the management and coordination of activities and the sharing of the resources of a computer, that acts as a host for computing applications run on the machine.

One of the primary purposes of an operating system is to handle the resource allocation and access protection of the hardware. This relieves the application programmers from having to manage these details.

Technical Support Resources

Application Support or Technical support (also called tech support, or IT support) is a range of services providing assistance with technology products such as mobile phones, televisions, computers, software products or other electronic or mechanical goods.  Examples of different types of technical support are:

  • Computer or PC
  • Server
  • Mobile phone
  • Electronic device

Technical support companies attempt to help users solve specific problems with a product.  Though most people associate tech support with computers, technical support may be necessary for almost any product, especially electronics. Most companies offer technical support for the products they sell, either freely available or for a fee.  These types of support services are usually referred to as a “help desk”. Help may be delivered via the telephone or online by e-mail or a website or a tool where users can log a call or incident. Larger organizations frequently have internal technical support available to their staff for computer related problems.

The internet is also a good source for freely available tech assistance, where experienced users may provide advice with problems.
