The intranet is essentially a small-scale version of the internet, operating with similar functionality, but existing solely within the firm. Like the internet, the intranet uses network technologies such as Transmission Control Protocol/Internet Protocol (TCP/IP). It allows for the creation of internal networks with common internet applications that can allow them to communicate with different operating systems (Newell et al 2000).
Although it need not be, the intranet is usually linked to the internet, where broader searches are implemented. However, outsiders are excluded through security measures such as firewalls.Details
