IT infrastructure is the combination of hardware, software, network and human resources that allow an organization to deliver information technology services to people within an organization. The most obvious is hardware. Without any hardware, it’s impossible to have any IT services at all. An organization needs desktop computers, servers, routers, switches and other equipment. Hardware is useless without software. Software is just as important to IT infrastructure as hardware. Typical software in an organization includes productivity applications, enterprise resource planning (ERP) and customer relationship management (CRM). Some of these applications might be bought off the shelf and others might be developed by the IT department, depending on the needs of the organization. The internet is essential to conducting modern business. That’s why network connectivity has become essential, since employees depend on email, web access, even their phone service through VoIP. A network connection is an absolute must. Plus, think of how many other machines have to be connected together. That means running wires and setting up networking hubs, switches and routers.
