A computer object in AD is used to model a real computer in an organizational network environment.
Say for example, I bought a new computer machine -01 in my organization, and want to allow people to access various organizational resources through this computer. All I have to do to achieve this is create a computer object in the Active Directory users and computers console and assign permissions to the computer object representing machine – 01. And depending on the permissions I assign to the computer object the users’ access over resources through this computer might be granted, restricted or denied.
