IT support refers to specialized services that technical entities offer to end users of particular technology products or services. In simple terms, IT support offers assistance regarding specific technical issues with either a computer system or a particular hardware product, instead of providing education, provision of modification or other service support. It may also be utilized in providing software product or system troubleshooting services, which may include the diagnosis of hardware problems and the provision of repair services. The most common IT support activities include the installation of new software and devices, updates and maintenance of networks, desktop maintenance, training users and maintaining documentation. The most common computer software used by individuals and businesses is the Microsoft Windows operating system. It is utilized in a vast number of devices, including computers, handheld devices, video game consoles and PIX (personal information interface) devices. A typical IT support specialist will have expertise in the majority of Microsoft Windows versions. Support specialists will also be familiar with hardware related technologies such as Sun Microsystems' Java and Unix platforms, Cisco's switches and routers, Microsoft Storage Area Networks (SAN) and Microsoft Windows Server. The types of expertise, an IT support specialist possesses will depend on the nature of support being provided. View for more. Computer hardware problems typically occur after the user has purchased, installed or executed a software application. When the hardware encounters a problem, it requires a different type of expertise than computer systems. For example, a PC user will need an IT professional to help them resolve issues related to a virus or other malware. On the other hand, a network administrator will be able to assist a person or company that has installed new technology devices in their network. The most common issues that the IT professional encounters when providing IT support services are the installation or maintenance of new technology devices, software and/or hardware, resolving hardware or software conflicts, upgrades, hardware or system setup problems, issues with Internet data transmission and problems related to the use of a company's data storage. As part of their job listings, IT support specialists are expected to be skilled in troubleshooting hardware problems, using the hardware itself to solve a problem, understanding the data conversion process, understanding various communication protocols, understanding how to troubleshoot a computer system, and understanding how to troubleshoot a network. It is also important for an IT support specialist to possess specific training in computer systems. IT support specialists should also be familiar with application software, billing, networking and email, web hosting, security, fax services, telephone and media access, office applications, and any other specialized knowledge that may be required. In today's IT support environment, there are two primary models of IT support: the on-site support model and the remote support model. A remote support model of IT support involves the use of phone, email, chat or video to provide IT support. The on-site support model usually involves the delivery of specialized equipment or personnel to provide on-site IT support. Remote IT support often requires the deployment of specific software or devices that are designed to handle IT support operations. The models that fall into the on-site or remote support models include support for hardware, applications, document and data recovery, upgrades, software, firewall protection, and configuration management.
