To Improve the Efficiency of Domain Controller Server in Cyber Security
Abstract: AbstractA domain controller server responds to security authentication request a window server domain. It authenticates user, stores user account user password and user information or enforces security policy for a windows domain server. A domain control server gives access to another domain in a relationship that user logging into a domain can access resources in another domain server. If the server performing domain control role is lost, the domain control …

Evaluation of System Study in Library and Information Science
Abstract: AbstractThe word ‘system’ has become a common term, often applied to things which seem large or complex. It is so frequently encountered, that it can become quite difficult to decide what it means even within a defined context. When a manufacturer of washing powder, computer programmers, doctors, economists, astronomers and ecologists use the same word, ‘system’, in describing their interests, can anyone be sure what they mean? What is the …
