Computer science is the study of computers and computational systems. It encompasses the theory, design, development, and application of the software and hardware components that make up these systems.
Computer scientists tackle a wide range of topics, such as algorithms (the step-by-step instructions to solve problems), programming languages (the tools used to write code), artificial intelligence (teaching machines to learn and think like humans), data structures (organizing and storing large amounts of information), and much
ARPANET (Advanced Research Projects Agency Network) was the first computer network that used packet switching to connect geographically dispersed computers and laid the foundation for the development of the internet. It was developed by the United States Department of Defense’s Advanced Research Projects Agency (ARPA) in the late 1960s and early 1970s to connect computers and researchers at various universities and research institutions. The U.S. government funded ARPANET to create
Active Directory (AD) is a directory service that connects users with the network resources they need to accomplish their tasks. It is Microsoft’s proprietary entity that runs on Windows Server and allows administrators to manage access permissions across networks. AD first emerged in the Windows 2000 system, intending to provide directory services to complex IT environments.
The directory stores information about objects, wherein an object may refer to network elements such as a user, group, device, or application. AD is responsible for categorizing these objects based on name
