Network Admission Control (NAC) refers to Cisco's version of network access control, which restricts access to the network based on identity or security posture.When a network device (switch, router, wireless access point, DHCP server, etc.) is configured for NAC, it can force user or machine authentication prior to granting access to the network.
In computing, a shared resource, or network share, is a computer resource made available from one host to other hosts on a computer network. [ 1 ] [ 2 ] It is a device or piece of information on a computer that can be remotely accessed from another computer transparently as if it were a resource in the local machine.
Any computer with an Internet connection or on a local area network can be remotely administered. For non-malicious administration, the user must install or enable server software on the host system in order to be viewed. Then the user/client can access the host system from another computer using the installed software.
