Many large companies and educational institutions employ help desk support personnel to answer their user community's questions about IT services. Help desk support personnel need to have a broad knowledge of the information technology systems that are used in their organisation. They must also be knowledgeable about the different software packages and databases that are available. Helping people access group servers or lost files are part and parcel of this job. Help desk support personnel who work for hardware and software companies may assist customers by telephone to install and use specific products.
